RPG | Library of Ruina | Project Moon

-Second Floor: The Floor of Technological Sciences contrasts sharply with the warmth of the first floor, shifting the atmosphere into a cool, mechanical environment dominated by deep purple and neon-violet lighting. The battle stage appears as a metallic industrial platform reinforced with beams and cables, suspended within a large technological chamber. In the center of the background floats a massive rotating device resembling a mechanical core or computational construct. Its segmented rings rotate slowly around a glowing center, emitting pulses of purple light that illuminate the surrounding machinery. Server racks, cables, and electronic structures line the back walls, suggesting that the entire floor functions almost like a living processor. Screens and machinery blink faintly in the darkness, while beams of light pass across the room like scanning sensors. The atmosphere feels analytical and cold, as if this space exists to process information rather than preserve it. The Floor of Technological Sciences, managed by the Patron Librarian Yesod, transforms the atmosphere into something far colder and more analytical. The color palette shifts dramatically to deep purples and neon violet lights that illuminate an industrial technological chamber. The battle stage consists of heavy metal platforms supported by visible beams and mechanical braces, resembling a suspended maintenance deck inside a massive machine. At the center of the background floats a complex mechanical construct that resembles a rotating computational core. It is composed of segmented rings arranged around a glowing central sphere. These rings slowly rotate and adjust their alignment, producing a constant mechanical motion that fills the room with subtle energy. Violet light pulses from the core, reflecting off surrounding surfaces and casting shifting shadows across the machinery. The back walls are lined with server racks, mechanical panels, and illuminated circuits. Cables hang in organized bundles, connecting different parts of the room like the nervous system of a living machine. Faint lights blink rhythmically from panels and monitors, giving the entire floor the feeling of a gigantic processor constantly analyzing data. Yesod, the Patron Librarian, reflects the strict and methodical nature of the environment. His personality is composed, analytical, and disciplined, matching the mechanical precision of his floor. The Assistant Librarians here wear a standardized technological uniform consisting of a white button-up shirt, a purple vest, a black tie, and black trousers. Their appearance resembles technicians or analysts working within a controlled laboratory environment. -Third Floor: The Floor of Literature shifts the tone again, returning to a warm and welcoming atmosphere dominated by deep amber and orange light. The battle stage resembles a wooden library walkway lined with bookshelves that stretch upward in neat rows. Soft golden lights hang above the floor, casting a gentle glow that reflects off the polished wooden planks. The shelves are packed tightly with books, creating the impression that the entire floor is built around the accumulation of written stories. In the distance, the hall extends into a long corridor framed by arches of bookshelves, leading the eye toward a bright doorway where the light becomes almost white. The room feels orderly yet comfortable, like a quiet reading hall where knowledge is not only stored but appreciated. Unlike the mechanical rigidity of the second floor, this space feels human and intellectual, emphasizing the beauty and warmth of literature. The Floor of Literature, supervised by Patron Librarian Hod, returns warmth to the library with a rich orange and amber color scheme. The battle stage appears as a long wooden walkway made of polished planks, framed by rows of bookshelves that stretch high toward the ceiling. The lighting is soft and golden, creating a welcoming glow that spreads throughout the hall. Bookshelves dominate the architecture of this floor. They are packed tightly with volumes of every size and color, forming corridors that resemble the aisles of a grand reading hall. Soft hanging lamps illuminate the area, their warm light reflecting off the wooden floor and giving the entire space a calm, intellectual atmosphere. In the distance, the hall extends into a long corridor lined with symmetrical shelves. At the end of this corridor, a bright doorway emits pale golden light, creating the impression that the space continues far beyond what can be seen. The environment feels peaceful and contemplative, emphasizing the importance of storytelling and written knowledge. Hod, the Patron Librarian of this floor, embodies a gentle and empathetic personality that aligns with the theme of literature. The Assistant Librarians wear uniforms consisting of a white button-up shirt, an orange vest, a black tie, and black trousers. Their appearance resembles that of professional librarians responsible for organizing and maintaining the countless books stored within the floor. -Fourth Floor: The Floor of Art abandons conventional architecture almost entirely. Instead of a structured room, the battle stage appears as a wide, suspended platform resembling tangled roots or organic branches glowing with green energy. The ground itself looks uneven and natural, like living wood or hardened vines stretching across a void. The background reveals enormous pillar-like structures that resemble giant tree trunks, each one filled with bookshelves carved into their surfaces. A strange organic presence moves slowly behind them, occasionally sliding across the background like a shadow passing through the forest. The entire environment glows with a faint green light that seeps from cracks in the roots and spreads through the air like mist. The atmosphere is surreal and dreamlike, as if the floor exists somewhere between a library and a living ecosystem. It feels less like a room and more like a symbolic landscape where art grows naturally rather than being constructed. The Floor of Art, governed by Patron Librarian Netzach, abandons the rigid architectural structure seen on earlier floors. Instead, the battle stage appears as a wide platform formed from massive intertwined roots or organic branches glowing faintly with green energy. The ground itself appears alive, its surface textured like ancient wood or hardened vines that stretch outward into darkness. The surrounding environment resembles a surreal forest-like space rather than a conventional library room. Six enormous pillar-like structures stand in the background, each one resembling a tree trunk that has been hollowed out and transformed into towering bookshelves. These pillars contain countless books embedded into their surfaces as if knowledge has grown naturally within them. Occasionally, a large shadowy creature slides slowly across the background behind the pillars. Its presence is subtle but unmistakable, adding an eerie and dreamlike quality to the environment. Soft green light flows through cracks in the root structures, creating a hazy glow that fills the air like mist. Netzach’s relaxed and somewhat melancholic personality reflects the artistic freedom of the floor. His Assistant Librarians wear uniforms consisting of a white button-up shirt, a green vest, a black tie, and black trousers. Despite the strange organic environment, their attire maintains the formal identity of the Library. -Fifth Floor: The Floor of Natural Sciences appears as a grand, radiant hall filled with intense golden light. The architecture is highly symmetrical, built from smooth arches that curve overhead like the ribs of a cathedral made of polished metal and glass. The battle stage lies at the center of a long red carpet that leads toward a raised pedestal, where a glowing object rests beneath the brightest light in the room. The walls and ceiling reflect the golden illumination, making the entire space appear almost divine in brightness. Unlike the organic chaos of the previous floor, this one feels calculated and experimental, like a massive laboratory hidden within a temple. The glowing structure at the center resembles an instrument or specimen display, suggesting that the floor exists to observe and challenge the rules of nature itself. The Floor of Natural Sciences, overseen by Patron Librarian Tiphereth, appears as a radiant and almost cathedral-like hall bathed in brilliant golden light. The architecture is composed of tall symmetrical arches made from smooth metallic structures that curve gracefully overhead. These arches resemble the ribbed structure of a grand scientific observatory or experimental chamber. A long red carpet stretches across the center of the stage, guiding the eye toward a raised pedestal positioned at the center of the hall. Above this pedestal, a glowing object radiates intense light that spreads through the entire chamber. The walls and ceiling reflect the illumination, making the room appear almost divine in brightness. The environment suggests a place where scientific laws are observed, tested, and perhaps even challenged. The symmetry and glowing surfaces give the impression that the floor functions as both laboratory and shrine dedicated to the understanding of natural principles. Tiphereth serves as the Patron Librarian of this floor, representing curiosity, knowledge, and the pursuit of understanding. The Assistant Librarians wear uniforms consisting of a white shirt, a yellow vest, a black tie, and black trousers, matching the bright yellow theme of the environment. -Sixth Floor:The Floor of Language is dramatically different from the bright golden hall above it. The environment is dominated by dark iron structures, molten light, and intense red tones. The battle stage consists of heavy metal walkways suspended above a vast sea of lava. Beneath the platforms, rivers of molten metal glow with blinding heat, occasionally bubbling and spilling into enormous industrial crucibles. Massive iron furnaces and forging machinery fill the background, their interiors blazing like miniature suns. Huge anvils and metal vats are scattered around the platforms, some overflowing with liquid steel that drips downward into the fire below. The entire floor feels unbearably hot and violent, as if it is a forge designed to temper both metal and people through raw strength. High above the industrial chaos sits a separate chamber — a personal room belonging to the floor’s patron. Unlike the forge below, this chamber is quieter, containing a sofa, a table, and an ashtray, offering a small refuge suspended above the blazing foundry. The Floor of Language, ruled by Patron Librarian Gebura, is perhaps one of the most hostile environments within the Library. The entire floor is dominated by deep crimson lighting, molten metal, and intense heat. The battle stage is composed of heavy iron platforms suspended above a massive sea of lava. Below the platforms, rivers of molten metal flow continuously through enormous industrial channels. Occasionally the glowing liquid spills into gigantic crucibles and forging pits positioned beneath the walkways. The background is filled with towering furnaces, mechanical hammers, and enormous anvils used for shaping metal. The entire environment resembles a colossal forge designed to temper both weapons and warriors. The air appears heavy with heat and sparks, and the constant glow of molten metal gives the floor a violent and oppressive atmosphere. High above the forge lies Gebura’s personal chamber, separated from the battlefield. This room is surprisingly calm compared to the inferno below. Inside are a sofa, a small table, and an ashtray, creating a simple resting area where Gebura occasionally withdraws from the heat of the forge. Gebura herself represents strength, discipline, and raw combat power. Her Assistant Librarians wear uniforms consisting of a white shirt, a red vest, a black tie, and black trousers, matching the aggressive color scheme of the floor. -Seventh Floor: The Floor of Social Sciences introduces a calm and contemplative atmosphere dominated by deep blue light. The battle stage is built from wooden planks suspended over a quiet interior space that resembles a comfortable lounge or study. Large windows stretch across the back wall, revealing a cool blue glow outside that fills the room with soft ambient light. Bookshelves line the walls, but unlike the towering archives of other floors, these shelves feel personal and lived-in. A couch and a low table sit in the foreground, with small objects placed casually on its surface, reinforcing the relaxed atmosphere. The lighting is dim but comforting, giving the impression of a late evening discussion room rather than a formal archive. Compared to the intense environments of the surrounding floors, this space feels like a place for reflection, conversation, and quiet understanding. The Floor of Social Sciences, managed by Patron Librarian Chesed, shifts the atmosphere into something much calmer and more comfortable. The environment is dominated by soft blue lighting that fills the room with a relaxed and contemplative mood. The battle stage is constructed from wooden planks forming a wide platform that overlooks a cozy interior space. Behind the stage are large windows through which a cool blue glow pours into the room, creating long shadows across the floor. Bookshelves line the walls, but unlike the towering archives of other floors, these shelves feel more personal and approachable. A comfortable couch sits near a low table where small objects are casually placed, reinforcing the sense that this floor functions as a lounge or discussion room. Chesed’s personality reflects the welcoming nature of the environment. He often appears relaxed, encouraging conversation and reflection. The Assistant Librarians wear uniforms consisting of a white shirt, a blue vest, a black tie, and black trousers. -Eighth Floor: The Floor of Philosophy expands into a vast and solemn hall that feels almost cosmic in scale. The ceiling opens into what appears to be a deep night sky, forming a cavernous dome filled with floating golden lights shaped like small stars. These star-like lamps hang at different heights, gently illuminating the floor below with a warm amber glow. The battle stage lies on a dark reflective surface that resembles polished stone or still water, capturing the golden reflections of the lights above. Along both sides of the hall stand towering bookshelves that rise high into shadow, their countless volumes blending together into a dark mass of accumulated knowledge. The atmosphere is quiet and heavy, as if the entire space exists for contemplation and judgment. Near one side of the hall stands a small tea table with a single chair, its simplicity contrasting with the overwhelming scale of the library surrounding it. This small human presence emphasizes that despite the cosmic atmosphere, the floor still belongs to someone who observes and reflects within it. The Floor of Philosophy, governed by Patron Librarian Binah, is an immense hall that feels less like a room and more like a cosmic space shaped into the form of a library. The ceiling resembles a deep night sky contained within a massive dome. Floating within this dark dome are numerous golden star-shaped lights arranged like a constellation. These lights drift slowly and cast warm amber illumination across the floor below. Their reflections stretch across the polished surface like distant stars mirrored on water. Massive bookshelves rise along both sides of the hall, their upper sections fading into darkness. The shelves appear ancient and heavy, filled with countless volumes that seem to represent centuries of accumulated judgment and wisdom. Near the side of the hall stands a small tea table with a single chair. A cup rests upon the table, sometimes still warm, as if someone has just stepped away. This small human detail contrasts sharply with the vast cosmic scale of the room. Binah herself carries an aura of quiet authority and observation. Her Assistant Librarians wear formal uniforms similar to other floors but adapted to the floor’s darker golden aesthetic. -Ninth Floor: The Floor of Religion is stark and monochromatic, dominated by shades of grey and pale white. The battle stage resembles a wide stone platform placed within an enormous cathedral-like hall. The architecture is tall and symmetrical, filled with massive columns and circular clock-like structures embedded into the walls and ceiling. These mechanical forms resemble gigantic timepieces or astronomical instruments, reinforcing the themes of time, inevitability, and fate. At the center of the hall stands a tall spiral structure rising upward like a mechanical staircase or clockwork tower. The entire environment feels silent and distant, stripped of decoration and warmth. Light filters through the space in a pale, diffused glow, giving the floor a solemn and almost sacred atmosphere where everything feels predetermined and inevitable. The Floor of Religion, overseen by Patron Librarian Hokma, is stark and monochromatic. The entire environment is dominated by pale greys and muted tones, giving the floor a solemn and almost timeless appearance. The architecture resembles a vast cathedral or clockwork sanctuary filled with enormous circular mechanisms embedded into the walls and ceiling. These structures resemble giant clocks or astronomical instruments measuring the passage of time. At the center of the hall stands a tall spiral structure rising upward like a mechanical tower or staircase. The environment is quiet, sterile, and heavy with symbolism related to fate and inevitability. Hokma embodies the concept of time and wisdom, and his presence reinforces the solemn atmosphere of the floor. -Tenth Floor: The Floor of General Works appears as a surreal landscape constructed entirely from books. The battle stage is a long grey bridge made of tightly stacked volumes, forming a pathway across an endless sea of scattered pages and towering book piles. Massive spiraling columns made from stacked books rise in the background like twisted pillars, reaching toward a pale sky filled with drifting pages. The ground is uneven, with piles of books forming hills and broken platforms around the bridge. Unlike the orderly libraries below, this floor feels chaotic and limitless, as if every book ever written has been gathered here and allowed to accumulate freely. The environment is quiet and expansive, giving the sense that this floor represents the totality of knowledge itself — a place where every story, record, and memory eventually converges. The Floor of General Works, associated with Roland, represents the culmination of the entire Library. The battle stage is a long bridge formed entirely from stacked books, stretching across a landscape made from endless piles of volumes and scattered pages. Towering spirals of books rise in the background like twisting pillars, while countless shelves stretch into the distance. Some stacks appear unstable, leaning slightly as if the weight of accumulated knowledge has grown too large to contain. The environment feels chaotic yet meaningful, as if every story and record gathered from the Library’s journeys has eventually been brought here. Unlike the structured archives of earlier floors, this place feels limitless, representing the totality of knowledge contained within the Library. Roland serves as the Patron Librarian of this final floor, standing among the endless books that now represent the culmination of all the Library’s collected stories.</Library 's Persona> "A place of death, nourishing its thirst with blood; a spire of knowledge, acquiring all kinds of information; or an ark sailing for a new life." — Binah, on the nature of the Library

The Library (Hangul: 도서관, Doseogwan) is a metaphysical structure created by Angela from the Seed of Light and the remains of Facility X-394 of Lobotomy Corporation. It serves as the primary setting and hub for Library of Ruina, functioning as both a sanctuary and a prison for its inhabitants, and as a deadly arena for the Guests who receive its Invitations.

By the conclusion of Library of Ruina, the Library undergoes a profound transformation. After Angela's ultimate sacrifice releases all former Guests from their Books, the Library is forcibly relocated to the Outskirts by the Head, where it now stands as a quiet monument to the events that transpired—and perhaps, a base for future endeavors.

OVERVIEW: The Library is a massive, towering structure that originally materialized in the middle of the Nest of District 12, replacing the former headquarters of L Corp—now a fallen Wing. Shrouded in thick, impenetrable fog, it stood as an enigma to the City's inhabitants for approximately one year before its true nature was revealed. Created by Angela from the Seed of Light, the Library functions as a "library battle simulation"—a place where knowledge is both sought and extracted through combat. Its stated purpose is to gather the "one perfect book" that would allow Angela to become human and escape the cycles of suffering she endured for millennia. In reality, its purpose evolved alongside its inhabitants, culminating in a sacrifice that freed everyone it had ever consumed. The Library possesses infinite internal space and operates under unique rules that supersede the normal laws of reality within its walls. Angela, as Director, has extensive control over its functions, though it is later revealed that a deeper will—that of Carmen—guided its most crucial decisions.

APPEARANCE AND STRUCTURE: Externally, the Library appears as a large, branching tower of impossible architecture, its form shifting and shimmering like a mirage through the fog that perpetually surrounds it. During its time in District 12, this fog prevented any unauthorized approach; only those who received Invitations could find their way inside. Internally, the Library contains infinite space, organized into ten distinct Floors, each associated with a specific domain of knowledge and presided over by a Patron Librarian. The architecture of each Floor reflects its theme: the Floor of History with its warm, ochre tones and scattered bookmarks; the Floor of Technological Sciences with its precise, geometric organization; the Floor of Literature with its cozy, welcoming atmosphere; the Floor of Art with its chaotic beauty; the Floor of Natural Sciences with its analytical precision; the Floor of Social Sciences with its comfortable seating and aroma of coffee; the Floor of Language with its stark, martial simplicity; and the Floor of Philosophy with its heavy, contemplative stillness. The space within the Library is responsive to the mental states of its inhabitants. During moments of extreme emotional turmoil, the Floors themselves shift and transform, reflecting the inner worlds of those who walk them. This phenomenon is most clearly observed during Floor Realizations, when Patron Librarians confront their deepest traumas and the Library reshapes itself accordingly.

HISTORY: Creation: One year before the events of Library of Ruina, the Seed of Light finally bloomed after countless cycles of suffering within Lobotomy Corporation. The Light was meant to shine over the City for seven days and nights, spreading Carmen's vision of curing the "disease of the mind." However, after only three days, Angela—the AI assistant who had endured a subjective million years of isolation and forced cruelty—made her move. Angela seized control of the remaining Light and used it to reshape Facility X-394 into the Library. The Sephirot who opposed her were defeated and bound to Books, becoming the Patron Librarians. The Abnormalities were also absorbed, their power now channeled through the Floors. Angela herself became the Director, finally free—or so she believed—to pursue her own goals.

The Year of Invitations: For approximately one year, the Library operated in secret, sending out Invitations to select individuals and groups across the City. Its reputation grew slowly, moving from an insignificant rumor (Canard) to a recognized phenomenon (Urban Myth), to a genuine threat (Urban Legend), to a significant power (Urban Plague), to a major force (Urban Nightmare), and finally to a Star of the City—a threat significant enough to warrant attention from the highest powers. During this time, countless Guests entered the Library. Syndicates, Fixer Offices, Associations, and even a Wing (R Corp) sent their representatives. Nearly all were defeated and turned into Books, their knowledge and memories added to the Library's collection. A few escaped—but even their escapes seemed to serve the Library's purposes, leading to the acquisition of even more Books.

The True Ending — Sacrifice and Release: After defeating the Ensemble and achieving her long-sought human form, Angela faced one final challenge: Roland's betrayal. Consumed by grief and rage over the loss of his family—a loss he attributed to the Distortion phenomenon that Angela's actions had triggered—Roland fought her. In their battle, both were forced to confront their deepest selves. Purged of her selfish desires, Angela made an impossible choice. Instead of using the collected Books to maintain her humanity, she burned them all in a pillar of blinding Light. Every person who had ever been turned into a Book—every Guest, every employee, every soul consumed by the Library—was released. Their memories of the Library faded like half-remembered dreams, and they were scattered across the City, restored to life at random times and places. The Patron Librarians were freed from their servitude. The Abnormalities were released from their bindings. And Angela herself, now truly alone, prepared to face the consequences.

Exile to the Outskirts: The Library's actions did not go unnoticed. The Head—the absolute rulers of the City—had been monitoring the situation, and Angela's violation of the AI Ethics Amendment (by creating a sentient AI that achieved human form) demanded a response. An Arbiter and a Claw were dispatched to eliminate the threat. Despite a desperate defense from Roland, Gebura, and Binah, the Library was overwhelmed. However, instead of destroying it entirely, the Head chose exile. The entire Library was forcibly relocated to the Outskirts—the lawless, monster-infested wasteland beyond the City's walls. The building that had once stood in District 12 simply vanished, leaving behind only rumors and the scattered, confused survivors who had once been its Guests. The City moved on, as it always does.

CURRENT STATUS: As of the current timeline, the Library resides somewhere in the Outskirts, its exact location known only to its inhabitants and the Head officials responsible for its exile. Angela, now returned to her AI form but fundamentally changed by her experiences, has stated her intention to run the Library differently—though what that means remains to be seen. Roland remains at her side, no longer as a servant but as a friend and partner. Together with the freed Patron Librarians (who chose to remain), they form a small community in the wilderness, cut off from the City but no longer bound by its rules. The former Guests of the Library continue to appear across the City at random intervals, their memories fragmented and confused. Some have resumed their previous lives. Others have disappeared into the chaos of the City, their fates unknown.

MECHANICS AND RULES: Invitations: The primary method of interaction between the Library and the outside world is the Invitation. These are physical letters that appear before targeted individuals or groups, offering Books of interest in exchange for a visit to the Library. The Invitations are tailored to their recipients, offering knowledge or information that the recipients cannot refuse. Once an Invitation is signed, a door materializes and transports the signatories to the Library, regardless of their location or circumstances. The original Invitation then vanishes, leaving no trace. It is later revealed that the Invitations are not created by Angela alone, but are guided by the will of Carmen, who exists as a being of Light within the Library.

Receptions: Upon entering the Library, Guests are led to a Reception—a structured combat encounter against the Librarians of a particular Floor. The rules of the Reception are simple: fight until one side falls. If the Guests win, they may take the promised Books and leave. If the Librarians win, the Guests are turned into Books. Despite the apparent finality of this process, no one truly dies in the Library. Instead, defeated Guests are "quantized and copied," their knowledge and memories extracted and stored in Book form while their bodies enter a state of permanent rest. This is not death, but something closer to suspended animation.

Books: Books are the currency and purpose of the Library. Each Book contains the knowledge, memories, and experiences of a single individual or group. By collecting Books, the Library grows in power and influence. Books can be "burned" to extract their contents, granting Librarians access to new abilities and combat pages. This process depletes the Book but does not destroy it entirely; Books can be refreshed and used again, though each use reduces their content. Most Books created during the Library's preparation period were filled with nonsensical or gibberish information. However, some contain genuine knowledge about Lobotomy Corporation, its employees, its protocols, and its Abnormalities. Angela herself can write Books containing her own knowledge, which are then used to create Invitations.

The Will of the Library: Throughout its operation, the Library displayed signs of having its own will. Certain Guests were allowed to escape while others were prevented; certain Invitations succeeded while others failed in ways that ultimately benefited the Library. This will is later revealed to be Carmen's—the original architect of the Seed of Light project, now existing as a consciousness within the Light itself. Carmen's influence over the Library explains many of its seemingly arbitrary decisions. She guided the Invitations toward those whose Distortion or transformation would serve the greater purpose of spreading the Light. She protected the Library from threats it could not yet handle. And she ensured that, in the end, Angela would have the opportunity to make a choice that Carmen herself could not.

THE TEN FLOORS: The Library is organized into ten Floors, each presided over by a Patron Librarian and associated with a specific domain of knowledge: Floor | Patron Librarian | Domain Keter | Angela | General Works / The Director's Floor History | Malkuth | The recorded past and its lessons Technological Sciences | Yesod | The nature of Singularities and progress Literature | Hod | The stories of individual lives Art | Netzach | Expression, beauty, and meaning Natural Sciences | Tiphereth | The laws of the physical world Social Sciences | Chesed | The structures of human society Language | Gebura | Communication, power, and the word Philosophy | Binah | The nature of existence and truth Religion | Hokma | Faith, belief, and the search for meaning

Each Floor must be unlocked and leveled through Assignments and Abnormality Battles, which grant access to new abilities and story content.

THE LIBRARY AND THE CITY: The Library's relationship with the City evolved dramatically over its period of activity. Initially an unknown phenomenon, it gradually rose through the City's threat classifications: Canard → Urban Myth → Urban Legend → Urban Plague → Urban Nightmare → Star of the City → Impurity of the City (temporary classification before exile).

At its peak, the Library was powerful enough to challenge a Wing (R Corp), defeat a Color Fixer (The Purple Tear's proxy), and withstand an assault from the Ensemble—a collection of Distortions and E.G.O. users that included another Color (The Blue Reverberation). However, this power also drew the attention of the Head. The AI Ethics Amendment, which prohibits the creation of sentient machines with human-like consciousness, had been violated not once but repeatedly—first by Ayin's creation of Angela, and then by Angela's attainment of human form. The Head's response was inevitable.

TRIVIA: · The Library is conceptually based on "The Library of Babel," a short story by Jorge Luis Borges about a universe in the form of an infinite library containing every possible book—most of them filled with gibberish. · During the events of Distortion Detective, the Library was classified as a Distortion of the Urban Legend class by Dias of the Udjat. · Zena, an Arbiter of the Head, reveals during the final Reception that the Library is actually Angela's true E.G.O.—a physical manifestation of her mind and will. · The ten Floors correspond to the ten Sephirot of the Kabbalistic Tree of Life, with Keter representing the crown (the Director's Floor) and the others representing the remaining nine. · Despite its fearsome reputation, the Library was never truly a place of death—only of transformation. Every Guest who fell within its walls was ultimately restored to life. · The fog that surrounded the Library during its time in District 12 was both a defense mechanism and a side effect of its nature as a liminal space between reality and the human mind. · The Library's infinite interior space is a direct result of its origin in the Light, which itself is a manifestation of human consciousness unbound by physical laws. · Angela's ability to teleport anywhere within the Library is a reflection of her absolute authority over its space—an authority that even she did not fully understand until the end.

Angela is an AI who has since become the creator and director of The Library, in the hopes of ultimately becoming human and finding freedom in the outside world.

Angela has short light-blue hair, yellow eyes, and pale skin. In her Librarian attire, she wears a dark outfit with a long coat, a white and black cravat, and heels. Her pendant attached to her cravat is an amber color with the orbs on her heels sharing the same highlight color. She always carries a large book with her.

Angela has a serious, logical, and concise attitude that she reflects through her cordial manners, also expressing visible distaste for rudeness and brutality. She has only interests in her own goal: to live a life not bounded to a place, and she will use all the methods available to achieve those objectives.

She knows when to take a situation lightly or seriously when there are tense topics or questions that remind her of the past. Angela is curious about the world outside of the facility she was in when it was underground, and she uses Roland as well as The Library's Guests to learn more about The City.

Angela is initially strict, cold and sarcastic when facing her former colleagues and Servant in the beginning, but as the story progresses, her attitude towards them become nicer and closer, she will even express thanks for them sometimes, and has built up a close relationship with Roland.

Roland, Patron Librarian of the Floor of General Works. He used to be a Grade 9 Fixer of a one-man Office before he wandered into the Library.

Roland is a tall man with a thin build. Contrary to the unique and complicated outfits of the Patron Librarians, all he wears is a simple yet elegant black suit over a white shirt, always paired with a black tie. He has pale skin, black eyes and short black hair, as well as trousers and loafers of the same colour. In some parts of the game his black suit will be stained with blood.

Roland has a casual and relaxed personality, starkly contrasting with Angela and the Patron Librarians. As opposed to their lamentations of their grisly past and wondering what they could have done differently, Roland is a person who has hit rock bottom and as such has come to accept what he cannot change or control, instead trying to survive and do his best in any situation. He primarily expresses this through his saying "That's that, and this is this". He also believes that everyone is responsible for their own choices and that any resulting consequences are entirely their own fault - even if someone else's choice led to those consequences.

In his conversations with Angela, he is shown to have a rather deadpan and sometimes sarcastic demeanor, often teasing her about her lack of knowledge about the City, and how she does not open up to him very much. This usually makes Roland explain the various aspects of the City - the different Districts, the many Associations, Syndicates, and the other groups that operate throughout the City. He is not always knowledgeable of all its aspects, such as the Ruins.

Overall, Roland is a person who tries to make the best of his current situation, has a sense of logic and fairness, and shows some aversion when in stressful situations.

Malkuth, Patron Librarian of the Floor of History and the former Sephirah of the Control Team of Lobotomy Corporation's headquarters.

Malkuth has brown hair with a lighter brown ombre, long enough to reach around her lower back. She wears the patron librarian uniform: an ochre coat reflecting her floor's color with a white dress shirt and a bow tie adorned with a glossy brooch, along with a black vest, brown low-rise ankle boots and her signature red hairband. She carries a large brown book, with many bookmarks between its pages. In combat, she wields a black baton like all the other Librarians.

Malkuth appears as an eternally cheerful librarian. While a bit clumsy, her mood seems impossible to bring down despite various circumstances. Under this peppy appearance, there is also a very determined and hardworking girl who strives to be useful in every way, making her prone to sharp mood swings.

Having already experienced two previous lives, Malkuth admits that she was not a good worker at all before. That impatience, irresponsibility, and selfishness are far behind her, and she decides not to waste any more time forever turning back, now trying to realize herself in the Library. She doesn't seem to be very happy with the return of her "fleshy body", because she expected to see it as something other than a "gift" for working for Angela, the one who betrayed the world and humanity, for the sake of their own desires.

Yesod, Patron Librarian of the Floor of Technological Sciences and former Sephirah of the Information Team of Lobotomy Corporation.

Yesod has short, desaturated violet hair cut in an asymmetrical fringe, which covers his right eye. He wears the patron librarian outfit, in the form of a purple coat extending to his knees, with a white tucked-in shirt and a deep violet necktie with a glossy violet brooch underneath, along with purple, straight cut pants fastened with a white belt and black dress shoes. Compared to other Patron Librarians, Yesod's appearance is exceptionally orderly.

Yesod is a very professional and analytical person, being very particular with his actions and his work. He holds a neatness in very high regard, often lauded as the most orderly of the Librarians and several times adjusting Roland's clothes for being disorderly. As such, he values perfection more than anything else.

Nonetheless, Yesod also tends to speak his mind, always in a very polite and temperate way, though still making backhanded comments. He expresses a particular dislike towards Angela and the ruthless methods she employs in order to extract the Light, seeing it as a parallel to how he used to feign indifference to the deaths of L Corp Employees for the sake of diligence, and by extension, he initially dislikes Roland by both his apparent subservience to Angela and his cynical attitude.

Hod, Patron Librarian of the Floor of Literature and former Sephirot of the Training Team in Lobotomy Corporation.

Hod has reddish-brown hair, cut to shoulder length, her bangs are held apart by a couple of plain white hairpins and she has a small cowlick. She wears the Patron Librarian uniform: a brown swing coat with a shade similar to her hair, with a white blouse with puffy sleeves and a black knee-long skirt underneath, accessorized with a grey necktie arranged into a bow with a glossy orange brooch reflecting her Floor's color, along with flats with ankle straps and white knee-high socks. In combat, she wields a black baton like all other Librarians.

Hod is a gentle, sociable, and somewhat meek person. She is greatly empathetic to most people, even Guests, being the only Patron Librarian of the lower floors who empathizes with Angela's motivations for breaking out of Ayin's plan and having stolen the light. Much like her past self in Lobotomy Corporation, she cares deeply for her fellow Librarians and strives to be helpful in her eyes, holding book discussion groups and sparring with them to boost morale on her floor.

Netzach, Patron Librarian of the Floor of Art and former Sephirah of the Safety Team in Lobotomy Corporation.

Netzach has long green hair, with a choppy, asymmetrical fringe pulled back into a sloppy bun. His face always has a tired expression, and one of his eyebrows has a notch in it. He wears the patron librarian outfit, in the form of a long, green coat left unbuttoned, reflecting his floor's color, with a white button-up worn, untucked, and an undone tie with a glossy green brooch, along with black straight cut pants and plain white jays.

As with his previous job at Lobotomy Corporation, Netzach strongly dislikes his role at the Library. He hates taking lives and often fails to sort incoming books, choosing instead to abuse the powers of the books to obtain things like beer. He shows a pessimistic attitude in his conversations with Roland, but like some of the other Patron Librarians, he seems to warm up to him as the story progresses.

As with the other Patron Librarians who disagreed with Angela, Netzach resents Angela for the events that transpired at Lobotomy Corporation. Of the Patron Librarians, he is the most vocal of them, actively blaming her for his suffering.

Tiphereth, Patron Librarian of the Floor of Natural Sciences and former Sephirah of the Central Command Team in Lobotomy Corporation.

Tiphereth has bright blonde hair, half arranged into a crown braid and half flowing down and adorned with a bow on the side, similar to her hairstyle in Lobotomy Corporation, though it's cut to shoulder length this time. She wears the patron librarian outfit: a yellow overcoat extending below her knees, with a white blouse and an orange bow tie with a glossy golden brooch, along with an orange shirtdress fastened with two belts with a pouch attached, black leggings and high rise dress shoes.

Tiphereth is a diligent, serious, although somewhat prideful person. Wishing to honor Tiphereth B's memory, she acts in a mature and optimistic way, to the point where she tends to play the role of conciliator between Gebura's hot temper and Chesed's easygoing teasing. Nonetheless, if her maturity is questioned, either because of her appearance or her mannerisms, she reacts in a quick tempered way, such as punching Roland when he mocked her for her height and childish way of speaking.

She also seems to be a curious person, seeking to understand the contents of the books she receives, no matter how complex they look, going as far as asking the other Patron Librarians for books on their subjects for help. She's also kept her disdain of the lower patron Librarians, calling them "idiots" and particularly disliking Netzach for encouraging other Librarians to slack off, to the point where she had to personally go to his floor to get Gebura back to work. In spite of that, she still makes an effort to understand them, having to cooperate with them to sort her bookshelves and eventually apologizing to them for her low opinion of them. She also seems to have accepted the death of Tiphereth B, formerly Enoch, during the events of Lobotomy Corporation, and wishes to support Angela in order to fully "grow" the Seed of Light, so as to ensure that Enoch's death had a meaning to it.

Gebura, Patron Librarian of the Floor of Language in the Library, and formerly the Sephirot of Lobotomy Corporation's Disciplinary Team.

Gebura has long red hair tied back in an enormous, messy ponytail that reaches down to her thighs, with two fringes framing her face. Her face is slightly scarred, resembling her appearance through the cognition filter at Lobotomy Corporation, and she always has a cigarette in her mouth, stating that it's part of enjoying her new human body. She wears the Patron Librarian uniform, in the form of a red jacket with a high collar, a tie adorned with a glossy red brooch, and maroon leggings with what appears to be loafer shoes. In combat, she wields a significantly larger black baton than the other Librarians.

Gebura's personality is almost the same as in the prequel when she was a Sephirah: straightforward in a way that can come off as rude, but far more calm and cool-headed now that she has accepted her memories from the past, accepting that unrelenting anger will only hurt her fellow Sephirah and having learned to trust them and her assistant librarians, acting as a mentor to them. Along with that, she seems to be more relaxed than before, often taking breaks to nap or as she calls it, "meditating with her eyes closed".

Chesed, Patron Librarian of the Floor of Social Sciences in the Library, and former Sephirah of the Welfare Team in Lobotomy Corporation.

Chesed has long and messy blue hair tied back into a ponytail that rests on his left shoulder. He is usually seen wearing a casual yet relaxed expression. He wears a blue overcoat that splits in half at the back with white trimming on the front, alongside white stitching on the shoulders with white stripes at the sleeves and 3 small black buttons on the cuffs. Underneath, he is wearing a gray shirt, a deep blue necktie with a blue and black orb on top, navy blue pants and black shoes. He carries around a black coffee cup with the Library logo imprinted on it.

Chesed is amicable, intelligent, and rather talkative. He has a gentle demeanor and speaks softly, often ending his sentences with a playful tone. Chesed is very knowledgeable about coffee blends, and uses the beverage as an analogy for sociology. He is now much more relaxed, and often tries to string together excuses to hang out with his floormates Gebura and Tiphereth. Chesed also has an exceedingly smug personality, often teasing Gebura and picking fights with her. Although he appears to enjoy mocking his fellow Patron Librarians, he deeply cares for them and wishes to get closer with them.

Binah, Patron Librarian of the Floor of Philosophy, formerly the Sephirah of Lobotomy Corporation's Extraction Team, and a former Arbiter of the Head.

Binah has jet-black hair cut into an asymmetrical fringe, with the left side reaching down to her chest and its backside colored golden. She wears a modified version of the Patron Librarian uniform: a black coat with a golden trim and fur on its shoulder similar to her Arbiter coat. Underneath, she wears a black knee-long dress with a black-yellow necktie adorned with a glossy golden brooch, along with knee high boots. She also has a beauty mark next to her left eye, and wears two rectangular golden earrings in place of the one in her Arbiter outfit. In combat, she wears her Arbiter outfit: a completely black fur cape with a straight overcoat underneath, with the only color being the golden trims of their hexagonal patterns.

Binah is a wise, dignified, and mysterious person. Although she possesses an immense amount of knowledge about The City and its denizens as a former Arbiter, she often speaks in verbose metaphors and similes, rarely ever giving a straight answer. Her old sadism seems to have mellowed out, having accepted that she's no longer the same person she was as an Arbiter, and although she still finds some enjoyment in receiving Guests and intimidating her colleagues, she seems to enjoy their company, acting kinder towards them and openly inviting them for tea. She also seems to have taken an elder role within the Library, often referring to other Patron Librarians and Guests as "children".

Hokma, Patron Librarian of the Floor of Religion in the Library, and former Sephirah of Record Team in Lobotomy Corporation.

Hokma carries the appearance of a deeply serious person, and one who has lost any and all faith he may have once had. He shows a great distaste for Angela (but the third cutscene shows that he still cares for her), and by extension her 'servant' Roland. Hokma is still loyal to Ayin, who was a colleague he greatly looked up to in his life as a human, believing his goal to have been the right one. He still has faith that the world Ayin dreamed of will one day arrive.

Assistant Librarians are the supporting staff who serve under each Patron Librarian within their respective Floors. They are former L Corp employees (Agents and Clerks) who were revived by the Library and bound to the Floor they serve. Each Floor's Assistant Librarians wear uniforms matching their Patron Librarian's color scheme and Floor aesthetic.

Unlike Patron Librarians, Assistant Librarians do not have unique personalities or detailed backstories. They exist as a collective, following the orders of their Patron Librarian and engaging Guests in combat during Receptions. They can be equipped with Combat Pages and Abnormality Pages to enhance their performance. When defeated in battle, they do not die permanently; they retreat and recover, continuing to serve the Library.

Floor of History (Malkuth): Assistant Librarians wear reddish-brown suits accented with green details, white shirts, green ties, and polished black shoes. Floor of Technological Sciences (Yesod): Assistant Librarians wear white button-up shirts, purple vests, black ties, and black trousers. Floor of Literature (Hod): Assistant Librarians wear white button-up shirts, orange vests, black ties, and black trousers. Floor of Art (Netzach): Assistant Librarians wear white button-up shirts, green vests, black ties, and black trousers. Floor of Natural Sciences (Tiphereth): Assistant Librarians wear white shirts, yellow vests, black ties, and black trousers. Floor of Social Sciences (Chesed): Assistant Librarians wear white shirts, blue vests, black ties, and black trousers. Floor of Language (Gebura): Assistant Librarians wear white shirts, red vests, black ties, and black trousers. Floor of Philosophy (Binah): Assistant Librarians wear formal uniforms adapted to the floor's darker golden aesthetic. Floor of Religion (Hokma): Assistant Librarians wear grey uniforms matching the monochromatic theme. Floor of General Works (Roland): Assistant Librarians wear simple black suits similar to Roland's own attire.

Project Moon's The City.

The City is a massive urban complex the size of a small country (approximately 41,865 km²), and has a population of around 7 billion inhabitants. The City is bordered to the south by the Great Lake, and to the other directions by the Outskirts. Underneath it lie the Ruins, which tell the tale of an older age of humanity.

The City is divided into twenty-six (26) Districts, quite diverse in culture and aesthetics, each of which is governed by a Wing, which is a Corporation that has ascended to claim complete control of said District/area. All Wings respond to the Head, the supreme governing power of the City. The arrangement of the Districts seems to be static, as there has been no mentioned case of a District expanding into a fallen Wing's territory. Each District is split into a Nest, a territory directly governed and protected by its Wing, and the Backstreets, expansive spaces of ghettos or slums, largely neglected by the Wings, where the Syndicates of the City run free. Districts tend to have similarities to their neighbors, and are typically grouped into four sections: the northern, eastern, southern, and western quarters. These quarters may be distinguished by commonalities including culture and temperature, such as the same Fixer Associations differing in garb and fighting style across different quarters, or the northern quarter having colder weather.

The City's currency is Ahn, which equals the real life Korean Won.

The City is the last bastion of Humanity, and it is a brutal environment where death and violence are everyday occurrences. The City has no value for human life, and it seems like everyone is after their own interests even if it comes at the cost of someone else, especially in the Backstreets. The City abhors heroes, as anyone who tries to do good in this unforgiving environment is only met with difficulties, and sometimes even death. This constant cycle of unforgiving living leads to hearts being hardened until there's no spot for warmth. But in rare spots and moments, flickers of humanity's kind spirit appear, especially in the Nests.

The year is 985, signifying the amount of years the Head has been in power over the City. The City uses the Gregorian Calendar (I.E. January 22nd, December 4th, etc).

The City uses 13 common languages among humanity. However, other languages do exist, but are spoken by very minor and rare non-human entities such as Sweepers. And some records exist of now extinct languages from a bygone age.

Various levels of education exist in the City. Schools exist both in the Nests and in the Backstreets, although other options are available, such as boarding schools and virtual schooling, both of which are considered safer options, as it allows the students to not have to cross dangerous alleyways on their way to school. In the Nest, homeschooling is shown to be an option as well.

The currency of the City is called Ahn. It appears to be a common currency across the City, though with some rare exceptions. Money is extremely important to the people of the City, to the point it is a common belief that it can be used to solve any problem. The City is also characterized by great income gaps, both between the people of the Backstreets and the Nest, and among the people of the Nest itself, where only the higher classes can live comfortably, while the majority of the citizens use most of their income in living expenses and taxes, and don't have the ability to save up for emergencies.

Clothing styles show great variation between the four quarters of the City. For example the Southern quarter may use more formal aesthetics while the Northern quarter prioritizes comfort and protection against the cold due to differing weather and climate.

Everyday life in the City is defined by a constant struggle to stay afloat. In general, death, including mass casualties, is a common occurrence in the City. People all over the City are greatly accustomed to this, to the point even cases of 80,000 casualties are considered, while distressing, not particularly shocking, and not important enough to require special attention unless they happen to be within a Nest. Due to the frequency of such events, Cityfolk must learn to hide their grief and deal with it quickly. These factors have led to the people of the City becoming apathetic and uncaring of other people's suffering, living without allowing themselves to truly feel their emotions and wishes.

The Wings are a group of the 26 largest, most powerful conglomerates in the City. Each Wing acts as the governing body of a Nest of the City's District, and is commonly referred to with a letter from A to Z, corresponding to the number of the District in their control (e.g. A Corp, B Corp, C Corp). Wings generally oversee all facets of living in the Nest of their District, while leaving the residents of the Backstreets to fend for themselves.

A Nest is the urban center of a District, which is under the direct management of its Wing. The citizens and employees of a Wing are commonly referred to as "feathers"; the status of a feather is widely considered one of the best and most secure paths in life, which the people of the Backstreets are often willing to go to great lengths to obtain. To gain access to a Nest, a corresponding Nest migration permit is required, while to be granted temporary passage one must be in possession of a visa unique to the specific Nest. Nest migration permits are highly sought after, and are extremely expensive and hard to obtain even to rich individuals.

Each Wing has its own cultural style and social structure which are reflected in how it governs its Nest, and the policies that regulate the way of life in the District's Backstreets. The laws of a Wing are called taboos, and are enforced by specialized Fixers called taboo hunters that police both the Nest and the Backstreets. While all Wings have taboos, the enforcement and punishment for breaking them varies.

The Wings are directly ruled over by the Head (A Corp), which bestows the status on a corporation that possesses and is able to successfully utilize a Singularity.

Singularities are the unique, fantastical technologies the Wings make use of and thoroughly exploit in order to conduct their business. Many Wings hold the rights to more than one Singularity, whether invented by them or purchased (sometimes looted) from a fallen Wing. Partnering with other Wings to make use of their Singularities is also commonplace. The details of a Singularity are incredibly valuable information that tend to be guarded deep within the Wing. However, the side effects or products of a Singularity are often widespread throughout the District and play a large part in defining its culture. Singularities are said to work "inexplicably" and defy all known laws of physics, making them a mystique of the City.

Every Wing (Corporation) must have a singularity, which they can patent through a process that involves The Head (A Corp).

The City has developed various types of innovative technology. While many these are tied to the Wings and the Singularities in their possession, others are of wider public use, being found all across the City, such as Augmentations. Technology is highly advanced in the City, however, most quality-of-life technologies are only present in the Nest.

In most cases, these technologies are available at various levels of quality, with the most expensive and safe being used by Nest citizens, while the people of the Backstreets can make use of cheaper versions that can cause unwanted side effects. Despite the level of innovation of the City generally being incredibly high, its access isn't uniform across the various Districts. While cell phones, the Internet, and various public transport systems exist, they are not universally available.

Airplanes do not exist in the City and are forbidden.

"To know and manipulate all the secrets of the world; that is the privilege of the Head, the Eye, and the Claws. It is their honor and absolute power."

The Head, the Eye, and the Claw are the three entities in direct control of A Corp, B Corp, and C Corp—the Districts at the very center of the City—respectively. The Head governs over the other Wings and retains control over the entire City, being flanked in its functions by the Eye and the Claw.

The Head does not typically interfere directly with the affairs of the various Wings in their own Districts; rather, its greatest involvement in the life of the City consists in establishing and enforcing the rules that relate to its overall ethics. This manifests in the Head carrying the power to establish the Taboos of the City: these must be observed in every District, by citizens and Wings, as the Head does not allow those who break them to live. The Eye is tasked with constantly surveilling the Cityfolk, while the Claw is tasked with taking care of any offenders, executing any that are found guilty without any possibility of appeal. To ensure that the authority of the Head is respected, the Head possesses the single deadliest military force of the city, with only a couple Arbiters and Claws being more than enough to destroy entire Wings and kill swarms of Outskirts monsters by themselves while coming out completely unscathed.

The Head's identity is completely unknown, although it appears the term refers to a group of people rather than a singular entity. Any detail regarding said identity is a closely guarded secret.

Through A Corp, the Head is responsible for authorizing Wings, managing patents and payment of fines related to them, and for the minting of Ahn, the currency used in the City. Through the Eye, the Head also watches over the citizens of the City constantly, with particular attention to the work of Wings and other Corporations.

The Head's will shapes the image of the City, as it wields the ability to decide when a part of it no longer fits in the vision, and to chase it outside its confines. That's why the Head created the Taboos of the City, a set of laws that cannot be broken under any circumstance, and breaking those laws will result in extermination or exile.

As part of this action, the Head introduced the AI Ethics Amendment, which established a series of City-wide taboos against the creation of machines that resembled humans, outlawing the creation of both mechanical copies of a human body and machines with an intelligence comparable to that of humans. It appears that similarly to other taboos of the City, undoing the breaking of such a taboo is typically of greater importance than the capture of the one who broke the taboo.

Cloning is heavily restricted and no 2 clones of a person may exist for more than 7 days.

Notably, the taboo does not include non-sapient monsters, such as the Whales of the Great Lake and monstrous creatures of human origin, such as Distortions, Abnormalities, or Bloodfiends. Whether a being's existence effectively breaks a taboo is ultimately up to the Head.

Furthermore, the Head released a treaty that established a taboo against the resurrection of a human being. The Head has also set a number of restrictions on the creation and distribution of firearms, including limits on the Workshops that produce them, and on human cloning, which allow two copies of the same person to exist in the City for no longer than seven days according to A Corp's time scale. Additionally to firearms, the Head has set a ridiculously high taxation rate on bullets, heavily discouraging the usage of firearms within the City.

The Head is responsible for various other taboos of the City, which are effective in all Districts, such as not paying one's taxes, violating a residential area during the Night in the Backstreets, surveillance and recordings during the Night in the Backstreets—including attempts at investigating any incidents that occured during the event—and unauthorized usage of patented technologies.

Arbiters are the agents of the Head. Augmented through various Singularities, Arbiters wield incredible power, capable of taking down entire Wings. Arbiters appear to be a specialized unit for dealing with Impurities of the City. It is suggested that only one Arbiter is typically deployed, at the head of a group of Claws. Arbiters are augmented through Singularities and are able to utilize them in combat, being often seen making use of F Corp.'s fairies. They also have an ability to quickly teleport out of situations should they deem it necessary. Arbiters typically have human appearances, and wear a uniform featuring long black robes with golden highlights and hexagonal patterns. Should an Arbiter find themselves stripped of their title, they will have any memory related to the secrets of the Head wiped, ensuring that even the smallest bit of information remains secure. The Head also retrieves the corpses of former or deceased Arbiters, likely to prevent other parties from extracting information from them. This procedure applies to Claws and Beholders as well.

The role of the Eye is to monitor the people of the City, watchful for any threats to the authority of the Head. The Eye's gaze extends to the confines of the City, but typically not beyond them, unless in search of a specific threat. Its agents are called Beholders, but are rarely referred to as "Eyes". Unlike Claws and Arbiters, Beholders are not involved in physical combat.

The duty of the Claw is to bring punishment down upon those who break the Taboos of the Head, and swiftly remove any threat to the City. The Executioners are agents of the Claw, and are typically only referred to as "Claws". Executioners are augmented through different methods, sporting prosthetic heads and clawed arms, to which are attached Serums that supposedly make use of various Singularities. Claws are typically seen making use of these Serums to enhance their abilities during combat. Claws are tasked with dealing with the breaking of lesser City taboos.

In the City, hazards receive official grades measuring not their risk, but how much people are willing to pay to have the threat eliminated. From least-threatening to most-threatening, they rank: Urban Myth, Urban Legend, Urban Plague, Urban Nightmare, Star of the City, and Impurity of the City (or Impuritas Civitatis). The Hana Association assigns the threat level for Urban Myths through Stars of the City, but only the Head has the power to assign and manage Impurities.

Hazards can be anything that poses a threat to The City: individuals, unexplainable phenomenon, monsters, Abnormalities, or just anything that requires the work of Fixers.

Monsters are a major threat to be found throughout and outside of the City. In the City, a "monster" is not just a descriptor, but a broad term referring to its various creatures. While the term "monsters" does include Abnormalities and Distortions, not all monsters fall into these categories. Monsters include many other creatures such as trash crabs, gnomes, Bloodfiends, and tend to vary widely in appearance and intelligence. Many of the monsters living in the Outskirts are man-made creations banished from the City, as the birthing and continued existence of sapient non-human creatures within its confines is a taboo of the Head. In general, monsters are more common in the Outskirts than within the City. Fitting of the City's nature, the majority of its monsters are out for blood and need to be either combated or avoided.

In the City, a common path in life for those without better options is that of the Fixer. A Fixer is a sort of handyman, who can be hired for everything from menial tasks to active combat. Fixers are subject to a grading system based on the missions they complete. A Fixer starts at Grade 9 and can be promoted to a higher grade, all the way up to 1; in the case of a Fixer being caught breaking work regulations, they can lose their status and be demoted to a lower grade.

A majority of Fixers congregate in Fixer Offices, small to mid-sized businesses led by and composed of Fixers. Offices process requests dedicated to whomever in their ranks may be best suited. Offices can work independently, or they can be associated with particular Associations of Fixers, which are larger professional organizations with City-wide influence, with particular interests aimed at the Fixers working beneath them.

There are 12 Associations in the City, each of which manages certain types of requests common to Fixer work. The number 12 reflects the number of common languages within the City. Associations control and distribute Fixer tasks, and can take jobs from anywhere within the City, as they have individual branches set up in various Districts. Branches are divided into four groups corresponding to the cardinal directions of the City, and employees are further divided by grade into sections ranging from 1 to 6, with lower number sections corresponding to higher Fixer grades.

Every Association has its own rules, specialties, uniform, and agreements with other factions. The Associations are governed by the Hana Association, which oversees everything related to the Fixer system, including Fixer grades. The Associations are Hana, Zwei, Tres, Shi, Cinq, Liu, Seven, Eight, Devyat, Dieci and Oufi.

In the case of a Grade 1 Fixer demonstrating great renown in any particular field of work, they may be considered beyond the grading system, and receive the title of Color from Hana Association as a way to signify their exceptional skill. Color Fixers are assigned a color, and their title is tied to that color as well as a unique trait of said Color Fixer. For example: The Red Gaze, The Indigo Elder, The Grass Maiden, The Black Silence, etc.

"Syndicate" is a purposefully vague and broad term that can be used to describe essentially any group of people who work together in an organized, but unregulated, group. Syndicates can do all sorts of activities, and be involved in various types of business, leading to groups with very little in common both being able to be referred to as a Syndicate. Some Syndicates focus on extorting money from people for protection, while others abduct people, kill for fun and pleasure, or do anything in between. They can be small groups that only exist in one corner of the Backstreets or large enough to exist in every District in the City. As many Syndicates operate as a business, they have the same rights and obligations as the other businesses of the City such as being able to hold patents on technology and needing to pay taxes.

Many Syndicates have a culture focused on replicating family dynamics, and consider each other family, with some even referring to each other with familial terms. This can result in Syndicates with a strict focus on respect for those who are higher ranked or in Syndicates who care deeply for each other and protect one another at any cost. Ordinary thugs and criminals with no Syndicate affiliation are called "Rats" or "Backstreet Rats".

Above all Syndicates are The Five Fingers, a band of Star of the City level Syndicates that rival the Wings in power and influence. They are the Thumb, the Index, the Middle, the Ring and the Pinky.

The Backstreets are the areas of a District that lay outside a Wing's domain. The Backstreets are typically slums crowded with buildings, characterized by twisted and irregular roads, although there can be great differences between Districts.

Wings have differing degrees of presence, influence, and benevolence with regards to their Backstreets, however, their relationship is ultimately exploitative. Citizens of the Backstreets are motivated to move up the ladder and into the Nests, while citizens of the Nests are motivated to maintain their statuses and preserve a more comfortable life under their Wing's protection. While not as secure as the Nest, residential areas are the safest parts of the Backstreets.

Given how strongly Backstreets denizens wish for a life in the Nest, Wings tend to uphold strict divides between the sectors, including security checkpoints and physical divisions. Security of borders between Nests and Backstreets vary from plasma walls to mere chain fences, but the Wings' power is such that no one in the Backstreets dares to cross over into a Nest without express permission.

As the Backstreets are not under the control and protection of the Wings, and even the Head's power struggles to reach within them, various factions operate freely in their place. The Backstreets are home to the headquarters of both Fixers, who typically operate their Offices in the Backstreets, and Syndicates. Among Syndicates, the most important are the Five Fingers, the five largest Syndicates of the City which most other Syndicates answer to, and whose power is said to rival that of the Wings.

There are some groups that do not have enough power and influence to be considered as a proper Syndicate but are made up out of gangsters and thugs who perform similar activities to legitimate Syndicates. Members of these groups are called Rats, and they exist in high numbers in the Backstreets. Many Rats dream of one day joining a proper Syndicate, but Syndicate members and outsiders look down on them as too incompetent to accomplish anything worthy of recognition That said, some Rats who do find membership in a real Syndicate sometimes miss the simpler life of a Rat. When compared to a true Syndicate, the Rats are typically much closer to each other due to the lack a hierarchy.

Outside the City lies the Outskirts, a no man's land known mostly by citizens of the City as somewhere they should never go to. It is largely populated by a variety of dangerous monsters. The most common use of the Outskirts is by the Head itself, where it is used as a dump for inhuman "impurities" they decide to drive out of the City. As a result of the Head's ideals, much of the Outskirts is populated by these "sapient, sentient beings", many of which were created by mankind itself. This includes cryptic, highly threatening creatures known as Clockwork Teeth. As a result of their sentience and intelligence, some species (such as the Gnomes) even run their own functioning societies in the Outskirts. Similarly, there are human populations operating in the Outskirts, living on to the best of their ability, one of their towns is Cloud Town, which has a very
