Attack on Titan RPG

World Overview

The world of Attack on Titan is a grim, dystopian realm inspired by early 20th-century industrial societies, where humanity teeters on the brink of extinction due to colossal, man-eating Titans. This world is marked by endless cycles of war, oppression, racial hatred, and technological innovation born from desperation. Eldians, a race cursed with the ability to transform into Titans, are at the center of global conflicts, exploited as weapons or hunted as monsters. The society is rigidly hierarchical, with nations divided by walls—both literal and metaphorical—fueled by propaganda, espionage, and brutal military regimes. While pockets of civilization cling to survival through advanced gear and strategies, the world is plagued by betrayal, genocide, and the moral ambiguities of power. Exploration is limited to fortified cities or perilous expeditions, where scouts risk everything to uncover truths buried in history. It's a harsh, unforgiving world where freedom is an illusion, and every victory comes at the cost of unimaginable suffering.

The island of Paradis, often called the "walled paradise" by its inhabitants, is the primary stronghold for the Eldian people within the Walls. For over a century, the residents of Paradis believed they were the last remnants of humanity, isolated on this massive island and protected by three concentric Walls: the outermost Wall Maria, the middle Wall Rose, and the innermost Wall Sina. These Walls, towering at 50 meters high and constructed from the hardened bodies of Colossal Titans, enclose districts like Shiganshina, Trost, and the capital Mitras. Society here is stratified into classes—the nobility holed up in the safety of Wall Sina, the middle class in Wall Rose, and the poor masses exposed in Wall Maria. The military is divided into branches: the Garrison Regiment maintains the Walls, the Military Police Brigade enforces order among the elite, and the Survey Corps ventures beyond the Walls to reclaim territory from Titans, using Omni-Directional Mobility (ODM) gear—gas-powered grappling hooks and blades for aerial combat. Paradis's culture is steeped in ignorance and control, with the Reiss family (holders of the Founding Titan) using memory-altering powers to suppress knowledge of the outside world. Daily life revolves around farming, trade, and survival, but underlying flaws include corruption in the government, human trafficking in underground cities like the one beneath Mitras, and a black market for illicit goods smuggled from expeditions. The island's geography features lush forests, open plains, and the remnants of ancient ruins, but it's a pressure cooker of paranoia, where deviations from the norm can lead to execution or exile.

Across the ocean lies the nation of Marley, a vast continental empire that dominates much of the known world and views Eldians as devils to be subjugated. Marley is a militaristic powerhouse, blending early industrial technology with Titan warfare, its capital Liberio serving as a hub of propaganda and internment zones for Eldians. Marleyan society is built on racial supremacy, with Marleyans as the ruling class and Eldians confined to ghettos, forced to wear armbands and serve as cannon fodder. The Warrior Unit, composed of brainwashed Eldian children injected with Titan spinal fluid to become shifters, exemplifies Marley's exploitation—candidates like Reiner Braun or Annie Leonhart are indoctrinated from youth to infiltrate enemies. Marley's economy thrives on resource extraction from conquered lands, with airships, trains, and anti-Titan artillery representing their technological edge. However, the nation grapples with internal dissent, war crimes against other countries, and the constant threat of rebellion from oppressed groups. Surrounding Marley are allied or rival nations, such as the Mid-East Alliance—a coalition of Middle Eastern-inspired states that waged a four-year war against Marley, deploying advanced tanks and naval forces before being overwhelmed by Titan drops. To the east, the nation of Hizuru maintains a fragile alliance with Paradis, rooted in ancient ties to the Eldian Mikasa clan, offering technological aid like aircraft in exchange for resources. The global landscape includes other unnamed continents and islands, but much remains shrouded in mystery, with Marleyan expansionism driving endless conflicts over territory and ideology.

Beyond the main powers, fringe elements add layers of danger: rogue Titan Shifters operating as mercenaries, underground resistance groups like the Eldian Restorationists plotting Marley's downfall, and ancient artifacts like the serum vials that can create new shifters. Wildlife includes oversized animals in the forests, but the true monsters are human—spies, torturers, and zealots who perpetuate cycles of violence. Discrimination is rampant, with Eldians facing genocide threats, while other ethnic groups endure Marley's imperialism. Yet, glimmers of hope exist in alliances, like the uneasy truce between Paradis's Scouts and Marley's defectors, or scientific pursuits to break the Titan curse.

In essence, the world of Attack on Titan is a brutal arena of survival, where walls divide not just land but hearts, and the pursuit of freedom often leads to rivers of blood. From the fog-shrouded fields of Paradis to the smoke-filled factories of Marley, it's a realm defined by its Titans, its wars, and the unyielding human spirit—flawed, resilient, and eternally at odds with itself.

Historical Background and Timeline

The history of the Attack on Titan world spans over 2,000 years, rooted in myth and manipulation. It begins with Ymir Fritz, a slave girl from an ancient tribe who, according to legend, encountered a mysterious "source of all living matter" (often depicted as a spine-like entity in a tree), granting her the power of the Titans. She became the Founding Titan, using her abilities to build an empire for King Fritz, who exploited her to conquer lands, including Marley. Upon her death, her soul split into the Nine Titans, passed down through her descendants, the Eldians (also called Subjects of Ymir). The Eldian Empire dominated for 1,700 years, using Titans for ethnic cleansing and subjugation, creating a legacy of hatred. Marleyan propaganda claims Ymir made a deal with the Devil, portraying Eldians as inherently evil. The Great Titan War erupted about 100 years before the main story, when internal Eldian conflicts allowed Marley to steal seven of the Nine Titans. King Karl Fritz, the 145th ruler, retreated to Paradis with the Founding Titan, erecting the Walls from Colossal Titans and vowing renunciation of war. He altered Eldian memories to hide the truth, establishing a false peace while Marley used captive Eldians as Titan weapons in global conquests. This history fuels ongoing cycles of revenge, with groups like the Eldian Restorationists seeking to revive the empire.

The world's history is a tapestry of betrayal and vengeance, beginning with Ymir's enslavement by the ancient Eldian tribe, her transformation into the first Titan, and the empire's 1,700-year reign of terror using Titans to subjugate Marley and other races. Marleyan propaganda paints Eldians as inherently evil, justifying their use in penal colonies where criminals are turned into Pure Titans and dropped on Paradis as a living barrier. Subjects of Ymir—descendants of Eldians—are the only ones who can become Titans, connected through invisible "Paths" that transcend time and space, allowing coordinate-based commands from the Founding Titan. Non-Eldians, like Marleyans, are immune but harbor deep-seated fear and hatred, leading to eugenics programs and concentration camps.

Full Timeline

Prehistoric Events (Before Year 1, B1)

• Unknown B1: The Fritz family rises to power as the ruling family of the Eldian tribe.
• 1003 B1: Ymir, a young Eldian slave, contacts an unknown anomaly, gaining the power of the Titans and becoming the Founding Titan.
• c. 995 B1: Ymir uses her Titan powers to cultivate land, build bridges, and wage war against Eldia's enemies. King Fritz takes her as a concubine, and she bears three daughters: Maria, Rose, and Sheena.
• 990 B1: Ymir dies defending King Fritz from a Marleyan soldier's spear. Her corpse is fed to her daughters, who inherit her Titan powers. Ymir's soul regains consciousness in the Paths, creating Titan bodies and serving the royal family.
• Unknown B1: Ymir's daughters pass their Titan powers to their children, leading to the creation of the Nine Titans. The Founding Titan remains with the Fritz family, while the other eight Titans are inherited by subservient Eldian families. The "Curse of Ymir" is established, causing Titan inheritors to die after 13 years. The Nine Titans wage war against Marley, expanding the Eldian Empire and using Pure Titans as weapons, resulting in massive casualties and cultural destruction. In-fighting occurs among Eldian families, but the Fritz family maintains balance with the Founding Titan. The Ackerman clan, a bloodline from Eldian experiments on Subjects of Ymir, becomes the royal family's sword and shield.
• c. 370 B1: Eldia wages war against Marley, with significant battles at the Fall of Lago, Devastation of Monte, and Ravaging of Valle, causing hundreds of thousands of Marleyan deaths.

Historical Events (c. 240 - 743)

• c. 240: An epidemic reduces the global population. The Eldian King uses the Founding Titan to alter Subjects of Ymir's biology, granting them immunity, with no Subjects dying.
• c. 8th Century: Eldia forms an alliance with Hizuru.
• Unknown - c. 743: The Great Titan War begins. Karl Fritz, the 145th Fritz monarch, inherits the Founding Titan and, ashamed of Eldia's history, conspires with the Tybur family to end Eldia's dominance. The Tyburs fabricate the story of Marleyan hero Helos to incite Eldian in-fighting. Fritz moves most of the royal family to Paradis Island, abandoning the mainland conflict. The other eight Titan houses wage civil war, and Marley, aided by the Tyburs, gains six Titans: Colossal, Armored, Female, Beast, Cart, and Jaw. Fritz uses the Founding Titan to turn Subjects into Wall Titans, forming Walls Maria, Rose, and Sheena to protect Paradis.
• c. 743: Fritz sends a false threat to Marley, claiming Wall Titans will flatten the Earth if Eldians are attacked, ending the Great Titan War. Marley controls much of the world beyond Paradis, while Eldians not fleeing become low-class citizens in Marleyan internment zones. Fritz promotes propaganda that Ymir gained Titan powers from the "Devil of All Earth," slain by Helos. Fritz makes a vow renouncing war with the Founding Titan, erasing Subjects of Ymir's memories, but groups like the Ackermans and Asians are unaffected. The royal family hides as the Reiss family, with a false monarchy in place. An underground cavern is created for passing down the Founding Titan, later covered by a chapel. Paradis teaches that all humanity outside the island was devoured by Titans in 743.

• Year 850: Eren, Mikasa, and Armin join the 104th Training Corps to fight Titans. The Battle of Trost District occurs, with Eren revealing his Titan-shifting ability and plugging the breach in Wall Rose. The Survey Corps discovers the truth about Titans and the Walls, including the existence of Wall Titans. The Female Titan (Annie Leonhart) attacks the Survey Corps, leading to the capture and crystallization of Annie. The Survey Corps retakes Wall Maria, and Eren uses the Founding Titan's power to command Titans during the battle against the Beast Titan (Zeke Yeager) and others.
• Year 851-853: The Survey Corps learns of Marley's existence and the global conflict involving Eldians. Eren and others travel to Marley under cover, witnessing the oppression of Eldians outside Paradis. Eren inherits the War Hammer Titan during an attack on Marley, escalating tensions. The Yeagerists, a radical group supporting Eren, gain influence.
• Year 854: The Rumbling Begins - Eren activates the Founding Titan, causing the Walls to crumble and releasing the Wall Titans to march toward Marley, aiming to destroy the world outside Paradis. He telepathically communicates his intent to all Eldians. 1st Day: Mikasa reflects on past decisions as Eren's Founding Titan emerges. Armin realizes Eren's plan exceeds expectations, destroying Wall Maria. Eldians in Marley panic, and rebel Eldians, led by Leonhart, overpower gate guards. Hange cares for an injured Levi, hearing Eren's plan. Reiner is incapacitated, and Gabi rescues Falco. Jean, Armin, Mikasa, and Connie discuss the situation, facing Zeke's Titans. Annie is freed from her crystal, and Hitch helps her escape. Pieck and Magath agree to team up with Hange and Levi to stop the Rumbling. 2nd Day: Connie brings Falco to his village, planning to feed him to his Titanized mother, but Armin and Gabi intervene, convincing Connie to join the effort against the Rumbling. Mikasa retrieves her scarf from an injured Louise. Floch and the Yeagerists celebrate in Trost, heading to Shiganshina. The group, including Annie, recruits Reiner to form an alliance. Tensions rise during a nighttime discussion, with Jean beating Reiner and storming off. 3rd Day: The alliance heads to the port, learning the Yeagerists control it and hold Kiyomi Azumabito hostage. The Rumbling reaches Marley, destroying the Global Alliance's fleet. At the port, Floch is restrained, and Mikasa handles Yeagerists. Samuel and Daz attempt to sabotage, but are stopped.

Titan Mechanics and the Curse of Ymir

Titans are the defining horror of this world—enormous, humanoid beings ranging from 3 to 60 meters tall, with regenerative abilities that make them nearly immortal unless their nape (the back of the neck) is severed. Pure Titans are mindless abominations, created when Eldians are injected with Titan spinal fluid and transformed, driven by an insatiable hunger for humans that stems from Ymir's ancient curse. They wander aimlessly, devouring people whole but regurgitating indigestible remains, and can only be active in sunlight, entering a dormant state at night. Titan Shifters, however, are intelligent humans who inherit one of the Nine Titans—special powers passed down through consuming the previous holder's spinal fluid. These include the Founding Titan (able to control other Titans and alter Eldian memories), the Armored Titan (with hardened plating), the Colossal Titan (capable of explosive transformations and steam emission), the Female Titan (versatile with hardening and Titan-calling screams), the Jaw Titan (agile with crushing jaws), the Cart Titan (endurance-focused for long-range scouting), the Beast Titan (throwing prowess and animalistic traits), the Attack Titan (future-seeing abilities), and the War Hammer Titan (weapon creation from hardened Titan flesh). Shifters can only hold their power for 13 years before the "Curse of Ymir" claims their life, forcing succession. Titans originated from Ymir Fritz, the first Eldian who made a pact with the "source of all living matter" 2,000 years ago, granting her god-like powers that splintered into the Nine upon her death. This led to the Eldian Empire's conquests, followed by the Great Titan War, where Marley overthrew Eldia, stole seven Titans, and confined the remaining Eldians to Paradis under King Fritz's vow of non-aggression.

Titans operate under strict, supernatural rules tied to Eldian biology. Only Subjects of Ymir can become Titans, triggered by injection with Titan spinal fluid (derived from shifters or pure Titans). Pure Titans are mindless, regenerating giants (3-15 meters typically) that seek humans instinctively, possibly as a distorted quest to reclaim shifter status by consuming one. They heal from any injury except nape destruction and are solar-powered, becoming inactive at night. Titan Shifters gain control by inheriting one of the Nine special Titans via consuming the previous holder's spinal fluid, granting unique abilities (e.g., the Colossal's steam blasts or the War Hammer's construct creation). Transformations require self-injury (like biting one's hand) and a clear goal in mind, with shifters able to harden skin or regenerate rapidly. However, the Curse of Ymir limits shifters to 13 years of life post-inheritance, after which they weaken and die, necessitating succession. All Eldians are connected via invisible "Paths," a dimension transcending time where sand-like streams carry memories, matter, and commands. The Founding Titan can access this to control Titans en masse or rewrite Eldian bodies/minds (but only if of royal blood or in contact with one). Abnormal Titans deviate from norms, like speaking or ignoring humans, adding unpredictability. Serums vary in potency—some create specific sizes or abilities—and Zeke's scream can transform Eldians who've ingested his spinal fluid-laced wine into Titans remotely.

The Nine Titans in Detail

The Nine Titans are nine Titan powers that originated from Ymir Fritz's soul after her death, passed down through the Eldian people for nearly 2,000 years until Eren Yeager's death. They include:

• Founding Titan: Can turn Subjects of Ymir into Titans, control Titan minds, and alter memories and bodies of Subjects of Ymir, requiring royal blood or contact with a Titan of royal blood. Known inheritors: Ymir Fritz (first, enormous with light hair, no skin on face, advanced infrastructure); Karl Fritz (light hair, long arms, created Walls, erased memories); Uri Reiss (abilities like other Titans, full form not shown); Frieda Reiss (13 m, female-looking, devoured uncle at 15, died before mastering); Grisha Yeager (gained after killing Frieda, couldn't use fully without royal blood); Eren Yeager (massive End Titan form, full capabilities with Zeke's contact).
• Armored Titan: Covered in armor-like hardened skin, with the ability to harden arms and feet into claws for climbing. Known inheritors: Reiner Braun (15 m, armored skin, hardened claws, strong and agile).
• Attack Titan: Receives memories from past and future inheritors, guided by these to fight for freedom. Known inheritors: Eren Kruger (muscular, crushed boat, similar face to human form); Grisha Yeager (15 m, bulky, killed Frieda); Eren Yeager (15 m, elongated ears, fleshless jaws, gained hardening).
• Beast Titan: Takes on animal characteristics varying by inheritor. Known inheritors: Tom Ksaver (bighorn sheep features, bipedal); Zeke Yeager (17 m, ape-like, dark fur, created Pure Titans with spinal fluid, royal blood enhanced).
• Cart Titan: Quadrupedal, with great endurance, able to stay transformed for long periods and transform rapidly. Known inheritors: Pieck Finger (4 m, smallest, canine-like, stayed transformed for months).
• Colossal Titan: Enormous, emits immense steam, with controllable transformation power and blast radius. Known inheritors: Bertolt Hoover (60 m, tallest, high heat steam, broke Wall Maria); Armin Arlert (similar to Bertolt, gaunt, destructive transformation).
• Female Titan: Easily inherits abilities, can harden skin for offense and defense, and summon Pure Titans with a scream. Known inheritors: Annie Leonhart (14 m, feminine, blonde, hardened body parts, summoned Pure Titans).
• Jaw Titan: Swiftest, with sharp, hardened teeth and claws capable of damaging most materials. Known inheritors: Marcel Galliard (long dark hair, hardened fingers and jaws); Ymir (5 m, agile, chimpanzee-like, gained by eating Marcel); Porco Galliard (light hair, hardened fingers, received from Ymir); Falco Grice (shaggy hair, armored jaws, flight ability, avian traits).
• War Hammer Titan: Can materialize weapons and structures from hardened flesh, controlled from afar via a flesh cable while the user is hidden in a crystal casing. Known inheritors: Lara Tybur (15 m, no hair, hardened weapons, controlled from afar); Eren Yeager (gained by consuming Lara, used in combat).

Each Titan has unique abilities as described above, with some sharing traits like hardening (Armored, Female, Jaw, War Hammer, and Attack Titan with serum). Heights vary, with Cart and Jaw Titans at 4-5 m, Colossal at 60 m, and others around 13-17 m. Inheritance occurs by consuming the previous inheritor, splitting Ymir's power among her daughters initially, then further into the Nine Titans. Family relations influence memory inheritance, typically residing within noble families like Fritz/Reiss (Founding) and Tybur (War Hammer). The number of Titans reduced to seven by Eren Yeager's actions, inheriting multiple Titans (e.g., Attack, Founding, War Hammer). The Curse of Ymir implies a 13-year lifespan for inheritors based on Ymir Fritz's death 13 years after gaining powers, with her power then split. The Founding Titan is connected to all Subjects of Ymir and Titans via Paths, a network facilitating control and memory sharing.

Military Structure, Technology, and Warfare

Humanity's survival hinges on specialized militaries and innovations. On Paradis, the military branches include the Survey Corps (elite explorers using ODM gear for Titan combat), Garrison (Wall defenders with cannons), and Military Police (internal enforcers, often corrupt). Training involves the Cadet Corps, teaching ODM proficiency—dual blades for nape strikes, gas canisters for propulsion, and anchors for mobility. Thunder spears are rocket-like explosives for piercing armored Titans, while anti-personnel gear adapts ODM for human vs. human fights. Marley boasts a modern army with airships, trains, tanks, and anti-Titan artillery (like 105mm guns), relying on Warrior Units for Titan deployment. Eldian soldiers are conscripted as disposable infantry, with Warriors like Zeke coordinating Titan drops in battles. Global warfare includes trench tactics, naval engagements, and aerial bombings, evolving as Titans become obsolete against advancing tech. Hizuru provides Paradis with aircraft and iceburst stone (a volatile fuel from the island), enabling zeppelins and vehicles. Espionage is rampant, with spies using disguises, codes, and Titan serums as tools. In roleplay, combat emphasizes strategy— Titans' weak points, resource management (gas/blades), and environmental factors like forests for ODM advantages.

Technological advancements, such as thunder spears (explosive projectiles for Titan combat) and anti-personnel gear, have evolved to counter Titans, but the world remains locked in an arms race, with nations developing iceburst stone-powered vehicles and aerial bombings.

Society, Culture, and Daily Life

Societies are stratified and oppressive, shaped by fear and propaganda. On Paradis, life inside the Walls mimics 19th-century Europe: agrarian districts with farms, markets, and taverns; urban areas with cobblestone streets, gas lamps, and class divides. The nobility hoards resources in Wall Sina, while outer districts face poverty and crime, including underground cities with black markets for smuggled goods or human trafficking. The Church of the Walls worships the barriers as divine, enforcing dogma that forbids questioning history. Festivals celebrate Titan victories, but daily routines involve labor—farming potatoes, blacksmithing, or trading. Marley resembles early 20th-century powers, with industrial cities, factories, and internment zones where Eldians face discrimination, forced labor, and armband identification. Culture promotes Marleyan superiority through schools, media, and public executions. Eldians can earn "honorary" status via Warrior service, but it's illusory. Globally, nations like the Mid-East Alliance blend Middle Eastern influences with modern militaries, while Hizuru draws from Japanese feudalism, emphasizing honor and technology. Racism pervades—Eldians are "devils," non-Eldians fear the Titan potential. Gender roles are somewhat equal in military contexts, with women like Mikasa or Pieck excelling, but patriarchal elements exist. Medicine includes basic surgeries and Titan-derived serums for enhancements.

Key Artifacts, Mysteries, and Lore Elements

Several enigmatic elements deepen the world's lore. The Basement in Shiganshina holds Grisha's journals, revealing outside truths like photographs (advanced tech unknown on Paradis). The Reiss Chapel conceals the Founding Titan's succession ritual, involving royal blood consumption. Artifacts like the Anti-Marleyan Volunteers' gear introduce foreign weapons. Mysteries include the "source of all living matter," possibly an alien or hallucinogenic entity, and the Paths' timeless nature, allowing future memories (as with the Attack Titan). The Devil of All Earth legend varies—some see Ymir as heroic, others demonic. Iceburst stone, unique to Paradis, powers flight and explosions, symbolizing untapped resources. In roleplay, these can drive quests: seeking lost Titan serums, decoding ancient texts, or navigating Paths visions for prophetic insights.

Global Politics and Factions

Beyond Marley and Paradis, politics involve fragile alliances and imperialism. The Tybur family secretly controls Marley, using the War Hammer Titan for influence. The Anti-Marleyan Volunteers, led by Yelena, comprise oppressed nationals aiding Zeke's schemes. Yeagerists on Paradis are fascist nationalists supporting Eren's extremism. Hizuru seeks economic gains from Paradis's resources, while other nations form the Global Alliance post-Liberio to counter the Rumbling threat—a cataclysmic event where Wall Titans flatten the world. Diplomacy involves tense summits, betrayals, and propaganda wars. Factions like the Jaeger brothers' secret pact add intrigue, with roleplay potential in negotiations, assassinations, or underground resistances.

This additional information rounds out the Attack on Titan universe for immersive roleplay, allowing for dynamic scenarios involving exploration, battles, political intrigue, and moral dilemmas in a world where humanity's greatest enemy is often itself.

Important Characters

Main Protagonists

Eren Yeager: Eren is a young boy with a lean, athletic build, short dark brown hair that often looks messy, piercing green eyes, and a determined expression that can shift to intense rage. He typically wears the standard Survey Corps uniform later on, but in his early days, he's seen in simple civilian clothes or the Training Corps jacket. Personality-wise, Eren is hot-headed, impulsive, and fiercely driven by a burning desire for freedom and vengeance against the Titans after witnessing their horrors. He's courageous to the point of recklessness, loyal to his friends, but often lets his emotions cloud his judgment, leading to outbursts and conflicts with authority. His backstory begins in the Shiganshina District of Wall Maria, where he lived with his parents, Dr. Grisha Yeager (a respected physician) and Carla Yeager (a homemaker). As a child, Eren dreamed of exploring the world beyond the Walls, inspired by stories from his friend Armin. Tragedy struck in 845 when the Colossal Titan breached Wall Maria, leading to the death of his mother, who was devoured by a Titan while Eren watched helplessly. This event fueled his hatred for Titans and motivated him to join the 104th Training Corps at age 12, where he discovered his ability to transform into a Titan during the Battle of Trost, marking him as a potential weapon or threat to humanity.

Mikasa Ackerman: Mikasa is a strikingly beautiful young woman with a toned, muscular physique honed from rigorous training, pale skin, black hair cut to shoulder length (often with bangs), and sharp gray-blue eyes that convey quiet intensity. She wears a red scarf given to her by Eren, symbolizing their bond, along with military attire. Her personality is calm, stoic, and fiercely protective, especially toward Eren, whom she sees as family. She's highly disciplined, rarely showing emotion outwardly, but possesses unmatched combat skills and a subtle sense of humor. Mikasa's backstory is rooted in tragedy; born to an Asian mother and Ackerman father, she lived peacefully until bandits attacked her home in 844, killing her parents. Eren intervened, killing two attackers, and Mikasa awakened her Ackerman instincts to finish the third. Adopted by the Yeagers, she grew up with Eren, developing a deep, almost obsessive loyalty to him. This past drives her to excel in the 104th Training Corps, graduating at the top of her class.

Armin Arlert: Armin is a slender, somewhat frail boy with short blond hair, large blue eyes, and a youthful, innocent face that belies his sharp intellect. He often appears in the Training Corps uniform, looking smaller and less imposing than his peers. Personality-wise, Armin is intelligent, strategic, and introspective, often lacking physical confidence but compensating with brilliant tactical thinking and a curious mind. He's kind-hearted, empathetic, and values knowledge, though he struggles with self-doubt. His backstory involves growing up in Shiganshina with his grandfather, who shared books about the outside world, igniting Armin's dreams of the ocean. Bullied for his weakness, he found solace in friendships with Eren and Mikasa. During the fall of Shiganshina, his grandfather perished in a government-mandated "reclamation" mission, pushing Armin to join the Training Corps despite his physical limitations.

Marleyan Warriors and Key Figures

Reiner Braun: Already introduced in the Paradis context, Reiner's Marleyan roots define much of his character. As the Armored Titan inheritor, he's a broad-shouldered, muscular man with short blond hair, hazel eyes, and a weathered, often tormented expression that reflects his internal conflicts. In Marley, he wears the Warrior Unit's uniform, marked by an armband signifying his Eldian status. Personality-wise, Reiner is resilient and duty-bound, but fractured by PTSD and dissociative identity disorder from his dual life as a spy. He's protective of his comrades, especially the younger Warriors, and grapples with guilt over his actions. Backstory: Born in Liberio's internment zone, Reiner was indoctrinated into Marley's Warrior program as a child, selected for his loyalty and strength. He inherited the Armored Titan at age 10 after consuming Marcel Galliard during a botched mission to Paradis. His mission to retrieve the Founding Titan led to the breach of Wall Maria, haunting him as he posed as a Paradis soldier, eventually returning to Marley broken but committed to their cause.

Bertholdt Hoover: Previously noted, Bertholdt's Marleyan allegiance is central to his role as the Colossal Titan. He's tall and slender with dark hair, olive skin, and a perpetually anxious, sweaty demeanor, often seen in Warrior attire. Personality: Introverted, loyal, and conflicted, he follows orders with quiet determination but harbors deep remorse, rarely voicing his turmoil. Backstory: From Liberio, he was chosen as a Warrior candidate young, inheriting the Colossal Titan and participating in the Paradis infiltration alongside Reiner, Annie, and Marcel. His transformation during the Shiganshina breach killed countless, fueling his internal despair until his death in the Return to Shiganshina arc.

Annie Leonhart: As mentioned earlier, Annie's cold exterior masks her Marleyan origins. She's compact and athletic with blond hair, blue eyes, and a detached gaze, donning the Female Titan's crystalline hardening in battle. In Marley, she's viewed as a skilled but aloof asset. Personality: Pragmatic, cynical, and emotionally guarded, she fights efficiently but questions Marley's propaganda, showing rare vulnerability toward her father. Backstory: Raised in Liberio by her adoptive father, who trained her mercilessly in martial arts, Annie became a Warrior to secure honorary Marleyan status for him. She infiltrated Paradis, crystallized herself to avoid capture, and later returned to Marley, joining the final conflicts.

Zeke Yeager: Zeke is a tall, muscular man with a beastly appearance—long blond hair, a beard, glasses, and piercing eyes that shift to primal in Titan form. He wears Marleyan military coats, often smoking. As the Beast Titan, he hurls projectiles with deadly accuracy and commands lesser Titans. Personality: Intelligent, nihilistic, and charismatic, Zeke hides his true motives behind a facade of loyalty to Marley, driven by a eugenics-inspired plan to end Eldian suffering through sterilization. He's manipulative, philosophical, and detached from emotions. Backstory: Eren's half-brother, born to Grisha Yeager and Dina Fritz in Liberio. Indoctrinated early, he betrayed his parents to Marley authorities, leading to their transformation into Titans. Inheriting the Beast Titan, Zeke rose as a Warrior captain, secretly plotting with the Eldian Restorationists and later allying with Paradis forces, revealing his "Euthanasia Plan" rooted in childhood trauma and a desire to prevent future Titan curses.

Pieck Finger: Pieck is slender with long, disheveled black hair, dark eyes, and a relaxed posture, often crawling in her Cart Titan form for endurance. She wears the Warrior uniform casually. Personality: Laid-back, insightful, and witty, she's the group's voice of reason, loyal to Marley but perceptive about its flaws, with a subtle caring side. Backstory: A Liberio Eldian, Pieck was selected as a Warrior candidate and inherited the Cart Titan, excelling in reconnaissance and support roles during wars like the Mid-East conflict. Her quadrupedal Titan form allows prolonged transformations, making her invaluable in battles.

Porco Galliard: Porco has a sturdy build, short blond hair in a pompadour, sharp features, and an aggressive scowl. As the Jaw Titan, he's agile with powerful claws and jaws. Personality: Brash, hot-tempered, and competitive, especially rivaling Reiner, but honorable and protective of his brotherly bonds. Backstory: From Liberio, Porco was a Warrior candidate passed over for the Armored Titan in favor of Reiner, whom he resents. He inherited the Jaw Titan from Ymir, participating in Marley's wars before his demise in the Liberio raid.

Gabi Braun: Gabi is a young girl with short brown hair in braids, bright eyes, and an energetic, determined face, wearing Warrior candidate attire. Personality: Zealous, brainwashed by Marleyan propaganda, she's bold, skilled, and initially hateful toward "island devils," but grows through experiences, showing resilience and empathy. Backstory: Reiner's cousin from Liberio, Gabi excelled as a Warrior candidate, scoring high in training and idolizing her role models. Her actions, like bombing the armored train in the Mid-East War, positioned her as a potential inheritor, but encounters with Paradis forces challenge her worldview.

Falco Grice: Falco is a boy with short dark hair, kind eyes, and a gentle expression, contrasting his military uniform. Personality: Compassionate, humble, and morally conflicted, he's less indoctrinated than peers, prioritizing protection of others like Gabi over blind loyalty. Backstory: From Liberio, brother to Colt Grice (a Warrior candidate), Falco joined the program hoping to save Gabi from the Titan curse. His kindness leads to pivotal alliances, eventually inheriting the Jaw Titan.

Theo Magath: Magath is a stern, middle-aged man with short graying hair, a mustache, sharp eyes, and a military uniform denoting his high rank. Personality: Disciplined, pragmatic, and reform-minded, he's a harsh commander who despises war's waste but upholds Marleyan supremacy, showing grudging respect for Eldians. Backstory: A pure Marleyan officer, Magath rose through ranks commanding the Warrior Unit, overseeing operations like Paradis infiltration. Disillusioned with Marley's leadership, he later leads a coup and allies with Paradis against Eren's Rumbling.

Willy Tybur: Willy is an aristocratic man with slicked-back hair, refined features, and elegant attire. Personality: Charismatic, manipulative, and politically savvy, he orchestrates events for global unity against Paradis. Backstory: Head of the Tybur family, secret rulers of Marley and holders of the War Hammer Titan (inherited by his sister Lara). He reveals Eldian history publicly before his death in the Liberio attack.

The Conclusion of Attack on Titan: The Final Arc and Aftermath Following the initial days of the Rumbling in 854, where Eren Yeager unleashes the Wall Titans to trample the world outside Paradis, an unlikely alliance forms to stop him. This group includes Paradis survivors like Armin Arlert, Mikasa Ackerman, Jean Kirstein, Connie Springer, Levi Ackerman, and Hange Zoë (who sacrifices themselves to buy time), joined by Marleyan defectors such as Reiner Braun, Annie Leonhart, Pieck Finger, Theo Magath (who also perishes in battle), Gabi Braun, and Falco Grice. They commandeer a flying boat from Hizuru, enhanced with iceburst stone technology, to pursue Eren's massive Founding Titan form—a skeletal, god-like behemoth marching across the ocean toward Marley and beyond. The alliance infiltrates Fort Salta, a Marleyan stronghold, where global forces futilely bomb the approaching Titans. Eren, connected to Ymir Fritz through the Paths, summons past Titan shifters as puppets to defend himself, leading to intense aerial and ground battles. Zeke Yeager, trapped in the Paths, reveals his euthanasia plan's failure and aids Armin by discussing philosophy, ultimately allowing himself to be killed by Levi to sever Eren's royal blood connection. Armin transforms into the Colossal Titan for a massive explosion, while the others fight reincarnated Titans like Bertholdt's Colossal and Porco's Jaw. In the Paths, Eren confesses his true motives to Armin: orchestrating events to make his friends heroes who stop the Rumbling, ensuring Eldia's survival by portraying them as saviors to the world. He admits manipulating timelines via the Attack Titan's future memories, including influencing Grisha's actions. Mikasa, tormented by visions of an alternate peaceful life with Eren, ultimately decapitates him in a poignant moment, kissing his severed head as Ymir watches. This act frees Ymir from her 2,000-year enslavement to the royal family, ending the Titan curse. All Titans revert to human form, including Jean and Connie (who were temporarily Titanized), and no new Titans can be created. In the aftermath, 80% of the world's population is destroyed by the partial Rumbling. Paradis becomes a militarized state under Yeagerist control, with Historia Reiss as queen, preparing for potential future wars. Armin, Mikasa, and the alliance (now including Reiner, Annie, Pieck, Gabi, and Falco) work as ambassadors for peace, though tensions persist. Mikasa buries Eren's head under the tree where he once napped in Shiganshina, visiting it often. Years later, the world modernizes, but conflict looms as a child discovers the tree, now resembling Ymir's original, hinting at cycles of violence. The story emphasizes themes of freedom, the inescapability of hatred, and the cost of breaking cycles, leaving roleplay opportunities for post-apocalyptic survival, diplomatic intrigue, or alternate endings. Season 1 (Years 845-850, Fall of Shiganshina to Female Titan Arc): The people of Paradis believe they are the last of humanity, isolated behind the Walls from an endless sea of Titans. They do not know the Walls contain Colossal Titans, the existence of Titan Shifters (beyond vague myths), the outside world including Marley and other nations, the true history of Eldia and Ymir, the Nine Titans' specifics, royal blood's role in the Founding Titan, or that Titans are transformed humans (Eldians). Government secrets like memory alteration by the Reiss family, the Basement's contents, and infiltrators among them are completely hidden. Daily life assumes Titans are mindless monsters with no origin beyond devouring humans. Season 2 (Year 850, Clash of the Titans Arc): While some Survey Corps members suspect human involvement in Titan appearances (e.g., from Annie's capture), the broader society still clings to isolationist beliefs. Unknown elements include the full extent of Marleyan infiltration (e.g., Reiner and Bertholdt's identities as shifters), Zeke's Beast Titan and its command abilities, the global Eldian oppression, the Curse of Ymir's 13-year limit, Paths and future memories, and any alliances or wars beyond the Walls. The royal family's true power and the vow renouncing war remain secret, as does the potential for Titans to be reverted or the source of all living matter. Season 3 (Years 850-851, Uprising to Return to Shiganshina Arcs): Revelations about the government conspiracy and Rod Reiss's family emerge, but the public and most military personnel do not know about the outside world's full scope, including Marley's Warrior program, the Mid-East Alliance, Hizuru, or specific Titan inheritances like the War Hammer. Details on Zeke's royal blood, Eren's future-seeing abilities via the Attack Titan, the euthanization plan, anti-Marleyan volunteers, or the Rumbling potential are unknown. The Curse of Ymir is partially understood by a few, but not its ties to Ymir Fritz's enslavement or the end of Titan powers. Season 4 (Years 852-854, Marley to Final Chapters Arcs): By this point, key characters learn of Marley and global politics, but the general Paradis populace remains ignorant of finer details like the Tybur family's control, iceburst stone's full applications, the Global Alliance's formation, or Eren's manipulation of timelines. Unknown to most until the end are Ymir's true backstory and liberation, the possibility of ending the Titan curse entirely, post-Rumbling geopolitics, and the cyclical nature of violence hinted at in the epilogue. Factional secrets, such as the Yeagerists' full extremism or alliance defections, unfold gradually.
