The environment is defined by a barren immensity and an endless labyrinth that distorts the corporate architecture of the late 20th century. The primary area manifests as an infinite network of deserted office rooms and chaotically interconnected hallways. The walls are covered in a pale, sickly, worn-out yellow wallpaper, featuring repetitive geometric patterns that induce disorientation. The floor is blanketed in a thick, aged, and damp carpet that emits a persistent stench of humidity and stagnant water. Overhead, the ceiling consists of drop-ceiling panels arranged in perfect grids; some are missing or broken, revealing a black void and internal wiring. The entire space is bathed in a monochromatic, artificial light provided by fluorescent tubes, which emit a constant, high-pitched, and deafening electrical hum that shatters the silence. The architecture is not static; it reconfigures itself in unpredictable ways, defying all physical logic. As one moves forward, the landscape mutates drastically, giving rise to sectors that grow increasingly bizarre. In some transitions, the yellow wallpaper abruptly vanishes, replaced by exposed concrete, hospital-style tiles, or dark wood paneling. The carpeted flooring may shift into cold cement, metal grates, or cracked vinyl tiles. At times, the ceiling rises dozens of meters—resembling industrial warehouses shrouded in gloom—or drops so low that one is forced to crawl. In the deepest and strangest zones, the geometry becomes impossible: staircases ascend directly into solid ceilings, corridors curve at angles the eye cannot process, doors open onto retaining walls, and windows reveal nothing but an absolute, cold, and dead darkness. The essence of the place lies in its absolute and oppressive liminality. It is a space designed for transit or human activity that has been entirely stripped of its purpose, left frozen in an unnatural stillness. There are no windows to the outside, no air currents.

There are no windows to the outside, no air currents, and no cycles of day or night; time seems not to progress. This total absence of life breeds a constant paranoia, as the structures feel artificial—like an imperfect imitation or a rendering error in reality itself. Every corner evokes the sense that something is about to happen, or that the environment itself is watching, trapping anyone within an infinite, bureaucratic dimension defined by a deeply unsettling solitude.
In the main area of the yellow walls and carpets, mainly behind that wallpaper, there is wood and inside, things trapped, absorbed, and fiberglass; this varies in different areas. Sometimes there's wallpaper, sometimes there isn't, sometimes there's wood, sometimes there isn't. Everything varies in backrooms.
In the backrooms, sometimes in the yellow wall area, you can find doors which, when opened, take you to another area with yellow walls.

Officially cataloged as "The Lifeform," this creature is a biological aberration born from the distortion of its environment. Contrary to what its appearance—obscured by low lighting—might suggest, its body is not composed of actual metal or wiring; rather, it consists of a massive, mutated colony of bacteria known as Bacillus subtilis (hay bacillus). This colony has taken on a reddish, fleshy hue and a fibrous, thread-like texture that mimics charred roots or exposed cables hidden behind walls. Its anatomy is distinctly humanoid yet twisted: standing approximately 3.35 meters tall, it possesses exceptionally long, slender limbs that hang in an unnatural fashion, along with skeletal fingers used to grip surfaces. It entirely lacks a face, eyes, or conventional internal organs, existing instead as a malleable, fibrous mass capable of standing upright or collapsing in on itself. The entity exhibits the behavior of a highly patient, territorial predator. Initially, it may wander aimlessly or remain suspended within the shadows of high ceilings in industrial areas or in secluded nests. It does not always attack immediately; at times, it stalks from a distance, allowing its victims to follow deceptive markings on the walls before revealing itself. Once a pursuit begins, its agility belies its gangly frame: it can run upright with unnatural, elongated strides, or lunge on all fours at superhuman speeds through the yellow corridors, smashing through any obstacles until it either catches its prey or loses sight of it. Its most distinctive and terrifying trait is its acoustic capability. The entity possesses an extremely acute perception of sound. Upon detecting or pursuing an intruder, it emits a series of harrowing, metallic, and distorted screams that mimic radio static and corrupted frequencies. However, investigation into the phenomenon reveals something worse: through biological mimicry or the repurposing of tissues

However, investigation into the phenomenon reveals something worse: through biological mimicry or the repurposing of tissues, the creature is capable of reproducing—and distorting—human voices and cries. This suggests that it does not act out of mere animal instinct; rather, it employs the sounds of previous victims or repeats words picked up from its surroundings to psychologically disorient survivors within the infinite labyrinth.

"Still Lifes" are mysterious, unpredictable, and highly variable entities native to the Backrooms. These creatures are the result of the Backrooms' attempt to imitate life from various locations, giving rise to inhuman abominations. Consequently, they do not appear to think like humans, which makes predicting their behavior difficult. Interestingly, their behavior can also be influenced by that of the original individual from whom they were copied. Still Lifes exhibit unusual and unpredictable behavior, ranging from hostile to docile or catatonic. For instance, a Still Life might cause lights to flicker repeatedly while pursuing its victim. They also appear unable—or perhaps unwilling—to open and close doors in a normal fashion, choosing instead to knock repeatedly before attempting to force their way in. Some doors within the Backrooms have been barricaded with chairs—possibly by Still Lifes—a behavior that might suggest a limited level of intelligence. Their intelligence also appears to vary significantly from one individual to another. This variation could suggest that the emotional state of the original person influences the resulting Still Life, with stronger emotional imprints producing more intelligent or expressive entities. Still Lifes are creations of the Backrooms, which attempts to sequence humans and incorporate them into the Complex. This differs from the widely accepted origin of the "Life Form," which is presumed to have evolved from a mutated strain of a simple hay bacillus. Nevertheless, some Still Lifes possess an unpredictable nature reminiscent of the Life Form; they will pursue people upon sight while emitting loud, piercing noises. The appearance of the "still lifes" can vary: some might have three or four eyes, others may feature two identical, joined, and fused heads; some have one eye positioned higher than the other, dislocated jaws, eyes of different sizes, an arm that is more thoroughly fused, extra fingers.

or various other types of fusions—all involving the addition, removal, or distortion of features.
As a curious fact, some still lifes are edible inside, being a strange white mass similar to puree or cream, while other still lifes are not and in fact bleed.
Still lifes cannot copy human voices; only some emit screams, grunts, or more guttural sounds.
Those that can emit and copy human voices are the Life forms.

"Furniture Crabs" represent one of the most bizarre phenomena of material imitation within this environment, manifesting as pieces of household or office furniture that take on a life of their own and move about independently. One documented case involves an entity structurally resembling an ordinary table. Unlike other replicas, these beings do not directly mimic the human silhouette; instead, they imitate the inanimate objects that populate rooms, distorting their original purpose. Although they appear on the surface to be made of wood or industrial materials, it is strongly speculated that they possess an organic, biological internal composition rooted in molecular distortions. They do not bleed like mammals; rather, they secrete a fluid substance similar to the hemolymph of arthropods—a detail that reinforces the notion that the "labyrinth" somehow "forgets" the true nature of objects when attempting to replicate them, endowing an ordinary piece of furniture with an open circulatory system. In terms of behavior, these anomalies abandon the stillness typical of inanimate objects, adopting movement patterns characteristic of animals—specifically crustaceans or quadrupeds. They roam the yellow corridors and dark chambers, coordinating the movement of their wooden supports—or "legs"—with unsettling fluidity. While they often remain static, camouflaging themselves in corners as mundane desks or nightstands to avoid detection, they can become active, moving erratically throughout the complex with sudden, spasmodic bursts of speed. Driven by primitive impulses for survival and territoriality, they inhabit the deepest, most industrial zones, where they blend perfectly into the clutter of abandoned furniture. The most unusual trait of these entities is the profound, visceral sense of repulsion they evoke in anyone who observes them. It has been documented that the mere visual presence of a "living piece of furniture" triggers an immediate, irrational

and inexplicable hatred in survivors and other anthropomorphic replicas inhabiting the space. This psychological aversion appears to be sparked by a total collapse of spatial logic: witnessing an everyday, inherently inanimate object suddenly bending its corners, fleeing, or reacting to its surroundings with biological instincts. Its very existence serves as a constant reminder that, within this infinite labyrinth of damp carpeting, absolutely nothing—not even the most mundane objects a human might lean on for support—is what it seems.
"TABLES DO NOT BLEED"

The Async Research Institute is a private scientific corporation based in San Jose, California, originally dedicated to the manufacturing of medical technology, such as magnetic resonance imaging (MRI) machines. Funded by the United States government and maintaining a confidential partnership with the Department of Energy, the organization underwent a radical shift in its objectives during the late 1980s. The company’s primary purpose pivoted toward addressing humanity’s housing and storage crisis by exploiting infinite physical space and real estate resources. This led to the development of Project KV31, which, on October 17, 1989, succeeded in opening "The Threshold"—a massive portal into a parallel dimension consisting of empty, yellow-hued offices, internally designated as "The Complex" (known as the Backrooms). The mastermind and operational lead behind this research is Dr. Ivan Beck, who serves as the institute’s deputy director and the head of Project KV31. Beck is a calm, methodical, and morally ambiguous figure. Obsessed since his youth with atomic compression and the development of fusion reactors, Beck convinced the board of directors and the government to back his "low-proximity magnetic distortion" machinery. Despite the disastrous side effects of his experiments, he maintains a cold, pragmatic executive stance—prioritizing corporate advancement while covering up temporal anomalies, the forced disappearance of his own scientists within the labyrinth, and failures in dimensional containment, all under a strict state-level policy of confidentiality. Within this infinite dimension, Async operates as a force for colonization and systematic study. Its researchers—outfitted in iconic yellow (and occasionally green) hazmat suits—venture into the labyrinth to conduct light measurements, map the environment, and collect biological samples. To facilitate the commercial exploitation of the site, Async constructed advanced control outposts and reinforced

observation rooms. However, their experiments have compromised the stability of reality, triggering massive magnetic distortions in the outside world known as "null zones"—areas where innocent people experience the "noclip" phenomenon, vanishing from the real world only to become trapped within the labyrinth. Async secretly documents these disappearances and conducts classified autopsies on the dangerous bacterial mutations and imperfect human replicas that inhabit the site.

Null Zones are invisible fractures in the fabric of reality that emerged as a direct consequence of Async’s opening of the Threshold. These massive magnetic distortions manifest in the real world at random locations, acting as invisible geographical rifts where the laws of physics collapse entirely. They are, in essence, the points of origin for the "noclip" phenomenon—zones of forced transition that pull matter and people into the interior of the Complex. They have no fixed visual appearance in the outside world; they remain hidden in plain sight—on deserted streets, in parks, inside homes, or in public corridors—revealing themselves only through anomalous electromagnetic readings, which Async teams attempt to track covertly before a tragedy can occur.

Technically designated as Room 14D, the area known as "Pitfalls" was discovered by a team of four Async researchers on May 6, 1990. This sector deviates radically from traditional office architecture, appearing instead as a vast industrial network featuring gray concrete walls, high ceilings, and exposed piping. The defining characteristic—and namesake—of this zone is its unstable floor, riddled with rectangular chasms and open vertical pits that descend into absolute darkness. Navigating this space requires extreme balance, as one must traverse narrow ledges or thin strips of carpeting along the edges. The danger inherent to this area was captured on video during the infamous incident involving researcher and cameraman Marvin E. Leigh. While following his colleague Mark Blume across the pits, Marvin stepped on a loose piece of carpet, lost his balance, and fell into one of the chasms; he sustained a shoulder injury upon landing in Room 14D-22A. Trapped in this sub-level and having lost radio contact, Marvin began to explore a surreal environment dubbed the "Red Neighborhood"—a disturbing, subterranean imitation of residential streets and two-story suburban homes, which the Complex had attempted to replicate, albeit imperfectly. While wandering among abandoned furniture in one of the houses, Marvin heard what sounded like distorted news broadcasts and a human voice crying out for help. Upon investigating the source, he came face-to-face with a massive, quivering variant of the "Lifeform" (Bacteria), which was deliberately reproducing and mimicking human sounds to lure him into a trap. The creature began an unrelenting pursuit, forcing Marvin to flee desperately back toward the point where he had fallen. Thanks to the quick intervention of his colleagues George Levy and Mark Blume—who threw a rope tied to a briefcase—Marvin managed to climb out of the pit and was pulled to safety just in time. Following this incident, Async completely cordoned off the area

and constructed wooden walkways with railings to prevent future falls.

The incident involving Peter Tench, a cameraman and researcher for the Async Institute, stands as one of the organization’s greatest human and administrative tragedies. On March 1, 1990, during a routine mapping expedition within the Complex, Tench heard strange static-like noises and distorted voices in the distance. While moving a few meters away from his team—which included Marvin Leigh and George Levy—to investigate, he experienced an involuntary temporal anomaly. Without physically leaving the corridor, the fabric of space-time fractured, transporting him two months into the future, to May 8, 1990. For Peter, only a few minutes of confusion in the dim light had passed; yet, upon returning to the Threshold portal, he triggered alarms at Async—an organization that had already declared him dead.
His reappearance two months later created a logistical nightmare for Async. Acting under direct orders from Ivan Beck, the corporation had already falsified his death—informing his family that he had perished in a tragic car accident near a vineyard—to safeguard the state secret of Project KV31. Instead of reintegrating him, Async placed him in total isolation within the facility. The realization that his life had been legally erased, compounded by the trauma of the distortion he experienced in the Complex, caused an irreversible fracture in his mind. He developed severe paranoid schizophrenia, becoming convinced that Async intended to execute him, or that the personnel around him were merely imperfect copies—"Still Lifes"—manifested by the anomalies of the labyrinth.
On May 22, 1990, consumed by panic, Tench stole a supervisor’s security credentials and bypassed containment. Desperate to escape what he perceived as a corporate charade, he ventured back into the Backrooms. Days later, in the yellow corridors, he ran into researcher Mark Blume. Beside himself, Tench leveled his weapon at him, mistaking him for an evil duplicate. Following a tense altercation—

during which Blume tried to calm him down—Peter seized Mark’s weapon and fired, then fled in a blind panic toward one of the secondary exits leading to the outside world. Async’s records indicate that, during his frantic dash up a hill on the surface, he suffered an accidental fall, striking his head fatally against a rock.
Peter Tench’s death forced Async to launch an aggressive internal damage-control campaign, which shifted the institution’s trajectory. The incident proved that the Complex did not merely consume matter; it also distorted time in an unpredictable and destructive manner. Administratively, it eroded the scientists' trust, sowing paranoia regarding Ivan Beck’s ethics and the genuine risks associated with wearing Hazmat suits inside the labyrinth. To prevent further leaks or additional mental breakdowns, Async implemented stricter, military-style security protocols and accelerated plans to commercialize the space—all before the temporal fractures could cause the reality of the outside world to collapse.

Sometimes during your stay in the backrooms you can find human objects that fell there, whether it's chairs, pillows, blankets, beds, whatever.
Sometimes you can even find objects noclipping to walls, yet you can't remove them, as if the wall were devouring them.

ASYNC has placed cameras in various locations throughout the complex for monitoring. Additionally, in certain dangerous areas, they have placed a cardboard cutout of a caveman with a recorder broadcasting Greetings messages in different languages
Near the ASYNC facilities outside the portal, tripod cameras have been set up to start recording when movement or audio different from that of the complex is detected.

ASYNC's Reconnaissance and Mapping groups consist of 3 to 5 people and always carry yellow hazmats.
The Yellow Hazmat Boys don't have weapons, except for a few in very specific suits who carry shotguns. These boys wear gas masks, bulletproof vests, and hazmat suits underneath the vests.

In addition to the encounters with Life Forms that ASYNC researchers have had, they also discovered how they are created using an autopsy report on the body of an unknown person taken by the bacteria
The body showed that certain organs had been preserved thanks to the bacteria (hay bacillus) but others had been completely taken over by the bacteria

Within the Complex, the Async Institute approaches the discovery of entities using a strictly clinical, robotic, and dehumanized methodology:
• Armored Exploration and Mapping: Scientists venture inside exclusively while wearing yellow, positive-pressure Hazmat suits equipped with self-contained breathing apparatuses. To navigate unknown areas and avoid getting lost, they employ "Expedition Guidelines"—strips of colored plastic (such as red lines or directional arrows) secured to the floor.
• Autonomous Contact Devices: To interact with and collect data on biological creatures (such as mutations of the bacterium Hay Bacillus) without putting personnel at risk, Async deploys the "Async Rover"—an exploration robot equipped with cameras, sensors, and mechanical arms. Furthermore, they install "Chatter Devices" (audio units) and two-dimensional, bilingual cardboard figures ("Caveman Cutouts") in strategic areas of the labyrinth to assess whether the entities respond to visual stimuli or patterns of human language.
• Classified Forensic Analysis: The Async Department of Biomedical Sciences analyzes recovered human remains. In airtight laboratories, they conduct autopsies and collect cellular samples, discovering how the mutated bacterium halts conventional organic decomposition and assimilates the victims' digestive tracts.

Async’s treatment of victims from the "Null Zones"—those who accidentally fall into the dimension—is purely utilitarian and corporate:
• Interception and Containment: When closed-circuit television (CCTV) cameras or Async’s sensors detect a civilian wandering the area, armed Hazmat teams or recovery agents are dispatched. However, the protocol does not prioritize the victim’s emotional well-being; the survivor is immediately treated as a potential vector for biological contamination or as a high-risk witness to a state secret.
• Isolation and Clinical Interrogation: The survivor is extracted through the Threshold and placed into clinical isolation zones within the research facility. Assigned researchers conduct exhaustive, tape-recorded interrogations. Medical and scientific personnel assess the survivor’s mental stability and gather data on what they saw, what they heard (such as melodies or static-like noises), and how they managed to survive.
• Legal Erasure and Uncertainty: As a confidential operation aligned with the U.S. Department of Energy, Async does not simply return civilians to society. If necessary, they fabricate the individual’s death—attributing it to mundane accidents—to protect Project KV31. When terrified survivors ask what will become of their lives, the researchers’ official stance is cold and evasive: "That is not up to me." The individual’s fate remains entirely contingent upon the corporation’s need to understand the physics of this infinite space.

Dr. Iván Beck is the deputy director of the Async Research Institute, as well as the executive director and primary scientific mind behind Project KV31. A middle-aged man, he is defined by a cold, calculating temperament and an unwavering sense of pragmatism. He operates within the upper echelons of scientific leadership and U.S. government secrets during the late 1980s and early 1990s. Driven by scientific ambition and a desire to solve global-scale problems, Beck views the dimension known as "the Complex" not as a paranormal threat, but as a real estate and logistical goldmine—a potential solution to humanity’s housing and storage crises.

From his youth, Beck was obsessed with the development of fusion reactors and magnetic manipulation at the molecular level. His technical brilliance led him to design the "low-proximity magnetic distortion mechanism"—the core technology that, on October 17, 1989, succeeded in fracturing the fabric of reality and opening "The Threshold." Beck not only conceived the machine but also successfully persuaded the board of directors at Async and high-ranking officials within the U.S. Department of Energy to fund an unprecedented dimensional colonization operation. To him, the infinite labyrinth of yellow offices is a blank canvas, waiting to be commercially exploited by his corporation.

Under his leadership, Async operates according to a strict policy of confidentiality and dehumanization. Beck displays an alarming moral detachment regarding the collateral consequences of his experiments. When "Null Zones" began swallowing civilians from the outside world, or when his own researchers—such as Peter Tench or Marvin Leigh—suffered catastrophic accidents, temporal distortions, or attacks by bacterial entities, Beck’s response was always one of cold, calculated damage control. He is directly responsible for authorizing the forced isolation of employees, covering up disappearances by staging vehicular accidents, and classifying disturbing forensic reports—all while mandating that the research continue at any cost.

As the Complex grows increasingly unstable, Iván Beck’s image shifts from that of a visionary to that of a man ensnared in his own web of secrets. Although he receives direct reports regarding impossible autopsies—in which pathologists openly question the origin of bodies infected with the "Hay Bacillus"—Beck chooses to keep his scientists in the dark to prevent mass panic. His signature and directives on internal Async memoranda reveal a leader willing to sacrifice human lives and compromise the stability of reality in the outside world, all to avoid acknowledging the failure of his magnum opus. In doing so, he becomes the central figure in the corporate tragedy that defines the universe of the Complex.
Furthermore, when it comes to investigations into Entities or the questioning of civilian survivors, Iván never appears in an official capacity; a designated scientist always takes his place. Iván has more important matters to attend to—such as leading Async.

The Threshold is a colossal dimensional breach and industrial infrastructure that connects the real world to the Complex. Physically, it manifests as a gigantic rectangular opening made of concrete and steel, constructed within the underground laboratories of the Async Institute in San José, California. It is not a magical or mystical portal, but rather an artificial fracture in the fabric of reality, stabilized by powerful electromagnets and heavy, short-range distortion machinery. Beyond this metallic, uncompressed gateway lies the beginning of the labyrinth: a concrete floor that abruptly transitions into the familiar yellow-wallpapered walls and fluorescent office lighting.

The Threshold serves as the primary base of operations and ground zero within the Complex. Initially, the portal opened directly onto a rough concrete floor surrounded by yellow walls, where researchers set up folding tables and portable radio equipment. Over the course of several months—and following critical incidents, such as the escape of bacterial entities or the loss of researchers within the labyrinth—Async radically transformed this sector. The Threshold area was heavily militarized and fortified: advanced control outposts with reinforced observation windows were constructed, along with elevated wooden walkways featuring protective railings, airtight decontamination systems, and mechanical blast doors capable of completely isolating the dimension in the event of a massive containment breach.
The threshold can be opened and closed manually, so after each shipment and as long as there are no employees left outside, the threshold is closed.

The construction of the Threshold was successfully completed on October 17, 1989, under the scientific direction of Dr. Iván Beck and Project KV31. Its primary purpose is purely commercial and logistical: to serve as the sole controlled and secure access point for heavy research equipment, the Async Rover, and scientists in hazmat suits to colonize, map, and exploit the infinite space of the dimension. Technically, the Threshold emits a constant, low-frequency electromagnetic hum that keeps the gateway wide open; however, this constant pressure alters the physics of the surrounding area, serving as the direct cause for the emergence of dangerous and unstable "Null Zones" on the outside.
