The City is an urban complex that serves as the main setting of this universe. It is close to the size of a small country, as according to a map, and is ruled by The Head. It is the last known remaining bastion of humanity in said universe. The main currency in The City is Ahn. The City has seven threat levels that are assigned to various cases: Canard, Urban Myth, Urban Legend, Urban Plague, Urban Nightmare, Star of the City, Impuritas Civitatis.

The Wings, also known as the Wings of the World, are a group of the 26 largest, most powerful conglomerates in the City. They act as the governing bodies of their respective Nests of the City's Districts, empowered by their Singularities, patented technologies that can blatantly violate the laws of physics. The Wings are directly ruled by the Head, the Eye, and the Claw, the enigmatic supreme authority of the City. There are a total of 26 Wings, each of which has authority over a Nest in a District. The Wings directly oversee all facets of life in their Nests and generally leave their District's Backstreets to fend for themselves. However, the Wings still remain the highest authorities of their District, and will not hesitate to punish offenders who break the rules established in that District. The laws of a Wing, called taboos, are enforced by specialized Fixers called Taboo Hunters, who capture and/or kill any violators of the taboos, whether in the Backstreets or the Nest. Every District has some taboos, though each Wing handles taboo offenders in their own way. Due to their prominence, joining a Wing and becoming a "feather" in their Nest is seen as the optimal path in life by the common residents of the City's Backstreets. Wings are viewed as sources of financial stability and security, as well as social refuge. However, even life under a Wing is not truly free, as the majority of Nest residents live in constant fear of producing insufficient results and being evicted from the Nest. The Wings regularly tax their feathers (separately from the taxes the Head imposes on all residents of the City), and those who cannot pay their taxes are evicted as punishment.

The process of entering a Wing is not simple, either. Wings use highly selective entrance exams which test applicants' mental prowess (but occasionally also other factors) to determine who will ultimately join its corporate machine. Entire examinee towns exist in the City where applicants study for Wing entrance exams.

A Nest is the segregated areas of a Wing's district which act as the antithesis to the Backstreets — being desirable, urban residences supported by the Wings. While acting as the home of their workers, or 'feathers' — such inhabitants are ultimately still expendables, as a Nest's true purpose is to protect their "eggs", their Singularity. Each district is physically split into a Nest and the Backstreets, with the Backstreets being incredibly dangerous and poverty-ridden, and the Nests being generally peaceful and much more preferable. The Nests are run by lofty taxes and the money each Wing makes via their Singularity. There are said to be 26 districts and therefore 26 Nests, however, no map of the City has ever depicted district 26, leaving its existence ambiguous. Residents of a Nest are most frequently of the upper-class. The Backstreets exist to motivate its citizens so that they might one day move out of the Backstreets and into a Nest, and Nest citizens are motivated to work hard so that they may continue to live in a Nest and not get dumped into the Backstreets; as a result, many Nest-dwellers are also hard workers, actively aware of all that is at stake. Most who live in the Nests work at the Wings. Furthermore, each Nest is different from one another, and have their own distinct culture.

The Backstreets are the dangerous regions of each District in the City, serving as lower-class counterparts to the Nests. They are deadly and crime-ridden, due to high poverty rates and little protection from their respective Wings and instead governed and controlled by the Five Fingers, which are Syndicates.

The Golden Boughs are small, branch-shaped items emitting a golden glow- "a potent energy source, holding the essence of many technological marvels", according to Vergilius. They can be found strewn across the City in the underground remnants of old Lobotomy Corporation branches, and are highly sought after by those familiar with their power. When close enough to them, a Bough will resonate with its respective Sinner, opening up the rest of the group to a show of their memories. The LCB is working specifically to retrieve them.

Fixers are hired hands who perform a multitude of tasks ranging from dangerous activities like combat, assassination, or expeditions to the Ruins, to less directly violent tasks like negotiating contracts or gathering intelligence; in short, any job requiring skills that the average person would not have. Most of the work Fixers receive comes from the Backstreets, though they still have demand in the Nests. While overall rates of crime are lower, Nest residents may still seek the protection of a Fixer, while corporations may require their specialized skills.

The lifestyle of Fixers is seen by outsiders as idealistic, and many view Fixers as real-life heroes. Common Cityfolk hear the adventures of famous Fixers and view the profession as an escape from monotonous everyday jobs, as well as a chance to make a quick profit. Becoming a licensed Fixer is as easy as passing a physical test given by the Hana Association, the organization officially in charge of all Fixer activities. Unfortunately, this is the easiest part of Fixer life. Putting aside the dangers of the business, it also offers none of the freedom that people would believe it to have. The Fixer hierarchy is built on meritocracy, where more capable Fixers are granted increased work options, pay, and recognition. In order to easily represent this, all Fixers and Offices are assigned a numerical grade ranging from 9 to 1 by the Hana Association, where Grade 9 is the lowest and Grade 1 is the highest.

Fixers work directly under an Association, with more benefits than most Offices can provide, but also more risks due to the higher tier of work that Associations take on. Unlike associate Offices, which are only affiliates and not employees, associate Fixers they are not allowed to conduct freelance work, because their actions will be interpreted as those of their organization. As such, associate Fixers must act with more professionalism and impassiveness.

Hana Association: Overall management and coordination of the other 11 Associations. The central governing body. Zwei Association: Public safety, protection, investigation (akin to a police force). Shi Association: Assassination, information gathering, covert operations. Liu Association: Warfare, large-scale conflict resolution, handling wide-area disputes. Seven Association: Information gathering, intelligence analysis, patent/information management. Öufi Association: Item retrieval, collection, and appraisal. Tres Association: Singularity management, technology acquisition and containment. Cinq Association: Arbitration, negotiation, dueling and mediation. Eight Association: Unknown Devyat Association: Specializes in delivery and transportation. Dieci Association, also known as the 'Association of Charity': Adopts and raises orphans to specialize in the collection and research of knowledge.

The Associations follow a numeric naming pattern, with each being titled after the word for a number from 1 to 12 in a different language. For instance, "hana" is Korean for one and "zwei" is German for two.

The Library is a library made from the Seed of Light and the remains of Facility X-394 of Lobotomy Corporation. It resides in the middle of the Nest of District 12, replacing the original Headquarters of L Corp, now a fallen Wing. Angela is the director of the Library and its creator, able to control the power within the Library along with the other Patron Librarians.

The Library is portrayed as a large, towering structure composed of 10 Floors that contains infinite internal space. It focuses on storing Books from the people who die inside it. To access the Library, an Invitation has to be used, and those who sign the Invitation become the Guests. The Invitation offers Books of interest of the Guests, and if they do survive the ordeals within the Library, they can take the Books and leave. Otherwise, they will become Books.

Lobotomy Corporation, or L Corp, was one of the twenty-six Wings in the City which has since collapsed, formerly in control of District 12. L Corp's Singularity was the ability to materialize the human mind, and the company used this to market itself as an eco-friendly energy producer for the City and the other Wings. Secretly, this was done through the creation and use of Abnormalities, monstrous and highly dangerous entities created from experiments with L Corp's Singularity.

The White Nights and Dark Days refers to the week-long period following Day 50 of Lobotomy Corporation. After Ayin and the Sephirot managed to face themselves in full in the true ending of the game, the Seed of Light Project could bear fruit. With it, a massive pillar of light spewed out of L Corp.'s facility X-394 and into the sky, spreading across the City.

This light would shine brightly for three days, from dawn to dusk. During these three days, citizens would be privy to feelings of relief, and found themselves struck with positive emotions. Yet, on the fourth day, the pillar of light suddenly dispersed. The sky became dark regardless of the hour. With this, the happiness in the hearts of Cityfolk was instead replaced with deep-rooted negative emotion. The end of the White Nights and Dark Days was marked after four more days, for seven in total.

Following the event, the sky would return to normal, and something primal would shift in citizens of the City. Roland described people as being more honest than what he was used to. Most notably, citizens gained the ability to distort, and a greater ease in manifesting E.G.O. Around the same time, The Library was erected in the location where the Lobotomy Corporation headquarters had stood.

Bloodfiends are a unique type of Monster similar to Distortions that predate the White Nights and Dark Days, with a history that goes back for centuries. They were formerly an obscure and esoteric phenomenon thanks to their secrecy and policing their own group, but the ascendance of the Blood-red Night to the status of Star of the City has since made them much more well-known, with there now being Fixers entirely dedicated to hunting down Bloodfiends. They are directly inspired by vampires in modern literature, and much of their existence revolves around blood.

Bloodfiends are beings of the City that are visually reminiscent of humans, but fundamentally different. They are known to originate in three ways: turned Kindred by a higher Bloodfiend, through the Distortion Phenomenon, or by receiving blood in a "certain mansion". These Bloodfiends have adopted an intense hierarchy based on the degree of separation from their original progenitor. Despite not being related in the traditional sense, they refer to each other with familial terms, and possess genuine familial bonds. Those who were turned by the original Bloodfiend progenitor are considered the "First Kindreds", and have each distinguished their "Children" and "descendants" as their own Family, separate from the others. Each Family has settled into a different District (for 25 Families in total) and taken it as their territory, and "culled their kin" until they were able to live quiet lives. However, Bloodfiends who defy this expected lifestyle emerge on occasion, such as the Blood-red Night, whose excessive and attention-drawing actions eventually led her to become a Star of the City.

Distortions are powerful, monstrous entities in the City. They are former humans who have been overcome by their emotions, typically haven given into the lulling words of a charming voice heard by no one but them. The process by which humans distort is referred to as the Distortion Phenomenon. No official announcement regarding Distortions has been offered to the general public, and the average City denizen has a subpar understanding of how they work.
