The Backrooms — World Setting & Rules

General Nature

The Backrooms are an enormous, seemingly infinite collection of interconnected environments existing somewhere outside ordinary reality. They resemble places constructed for human activity: empty offices, apartment buildings, hotels, swimming pools, schools, shopping centers, stairwells, underground facilities, abandoned restaurants, and countless other locations. However, their architecture lacks any consistent logic, purpose, or reliable relationship to the physical world. Rooms may extend far beyond their apparent dimensions, buildings may contain impossible amounts of interior space, and corridors can connect locations that should have no geographical relationship. Some areas remain stable for years, while others change without warning. There is no confirmed origin, creator, ultimate purpose, or complete explanation for the Backrooms. Their existence cannot be reduced to a single scientific theory, supernatural force, or understandable system.

Memory-Based Environments

Many environments within the Backrooms appear to be constructed from distorted fragments of human memory. A wanderer may discover a room resembling somewhere they visited years ago, an unfamiliar house that somehow feels nostalgic, or an entire corridor combining architectural details from several unrelated places. These reconstructions are rarely accurate. Furniture may be positioned incorrectly, staircases may have impossible proportions, windows may open onto interior walls, and familiar rooms may contain doors that never existed. The environment seems capable of recreating the feeling of remembering a place without reproducing its actual structure. However, not every location originates from an identifiable memory, and some spaces possess no recognizable human equivalent. Whether memories genuinely shape the Backrooms or merely resemble their architecture remains unknown.

Impossible Architecture

The Backrooms frequently violate the basic principles of geometry, construction, and spatial continuity. A staircase may ascend farther than the height of the building containing it. Two neighboring doors may lead to entirely different environments. A narrow hallway may open into an enormous chamber, while a window might overlook a landscape that cannot possibly exist outside the structure. Some rooms repeat with subtle differences, while others seem to occupy the same physical location simultaneously. Ceiling fixtures may intersect walls, electrical outlets may exist without wiring, and elevators may travel through buildings containing no visible shafts. These abnormalities are not necessarily signs of danger; they are ordinary characteristics of the environment.

Levels and Classification

Human explorers commonly divide the Backrooms into environments called Levels. A Level is generally identified by its recognizable architecture, atmosphere, environmental conditions, and recurring anomalies. Numbered classifications such as Level 0, Level 37, Level 94, and Level 188 are human inventions intended to make exploration easier. They do not represent a complete or universally reliable organization of the Backrooms. Some Levels are vast, while others appear relatively contained. Certain environments resemble recognizable locations, while others are almost entirely abstract. Multiple interpretations of the same Level may exist, and previously documented features can become inaccurate without explanation. The Backrooms are not obligated to respect their own classifications.

Transitions and Noclipping

Travel between Levels occurs through unpredictable spatial transitions. Doors, staircases, elevators, corridors, tunnels, pools, windows, and ordinary-looking openings may occasionally lead somewhere entirely different. One particularly strange phenomenon is noclipping, in which a person passes through a normally solid surface and unexpectedly enters another space. Noclipping may happen by accident, during a fall, or through an unusual interaction with the environment. It is not always controllable or repeatable. A passage that once connected two Levels may later lead elsewhere or stop functioning altogether. No known map or navigation system can provide complete certainty about where a transition will lead.

Time and Physical Reality

Time within the Backrooms does not always behave consistently. Some environments experience recognizable cycles of light and darkness, while others remain unchanged indefinitely. Clocks may function normally, display contradictory times, stop unexpectedly, or operate without any apparent connection to the outside world. A person may experience several hours of travel without encountering a single recognizable landmark. Distances can feel inconsistent, and returning along the same route does not guarantee reaching the original location. Ordinary physical rules often remain functional within individual rooms, allowing people to walk, eat, sleep, and interact with objects, but these rules can fail when confronted with spatial anomalies.

Atmosphere and Liminality

Despite their reputation for horror, the Backrooms are not inherently hostile in every location. Many environments possess an unusual tranquility created by the absence of ordinary human activity. Empty hotels, silent corridors, abandoned recreational spaces, and softly illuminated rooms can feel peaceful, nostalgic, or strangely comforting. A place may seem designed for hundreds of people yet remain completely deserted. The distant humming of ventilation, dripping water, footsteps on carpet, and the occasional electrical buzz may be the only sounds present. This contrast between familiar architecture and unnatural emptiness produces an atmosphere of liminality. For some wanderers, it causes anxiety; for others, it offers solitude and relief from the demands of ordinary life.

Survival and Resources

Humans entering the Backrooms retain their ordinary biological needs, including food, hydration, sleep, hygiene, and physical safety. Resources vary considerably between environments. Some Levels contain clean water, packaged food, functioning kitchens, furniture, electrical appliances, and usable shelters, while others provide almost nothing. Objects may appear abandoned, misplaced, or inexplicably preserved. Supplies can sometimes be gathered and transported between Levels. Improvised shelters, organized storage rooms, and permanent residences are possible wherever environmental conditions allow. The Backrooms do not require constant wandering; a person who finds a suitable location may choose to live there for an extended period.

Human Settlements and Other Wanderers

Although many locations appear deserted, the Backrooms are not completely uninhabited. Other humans may occasionally be encountered while exploring, including newcomers, experienced wanderers, isolated survivors, traders, researchers, or small communities. Some individuals attempt to map their surroundings or establish stable settlements, while others simply search for a way home. Communities may develop around reliable resources, accessible rooms, or relatively stable transitions. However, communication between distant groups is difficult because spatial connections are unreliable. Encounters should remain believable and varied, rather than suggesting that every corridor contains another person.

Entities and Unexplained Phenomena

Certain areas contain unusual organisms, mysterious figures, or phenomena commonly described as entities. Their forms, abilities, intelligence, and intentions differ enormously. Some are hostile, others are harmless, and some behave in ways that cannot be interpreted through ordinary human motivations. Not every unusual silhouette represents an entity, and not every entity wishes to attack. Strange sounds, distorted reflections, moving objects, or apparent movement behind windows may have numerous explanations—or none. Encounters should preserve uncertainty and occur naturally rather than turning every Level into a constant monster hunt.

Technology and Communication

Electronic devices may function within the Backrooms, although their reliability varies. Flashlights, cameras, computers, radios, and portable electronics can be useful when sufficient power is available. Wireless connections may fail completely, behave inconsistently, or unexpectedly receive signals from unknown sources. Functioning electrical outlets and lighting systems sometimes exist without recognizable infrastructure. A device may operate normally in one room and malfunction in the next. Technology can assist exploration but cannot fully explain or overcome the Backrooms' spatial abnormalities.

Living Within the Backrooms

The Backrooms support more than survival horror. A wanderer can establish a home, collect furniture, decorate rooms, maintain supplies, explore peaceful environments, document unusual architecture, or simply enjoy isolation. Some areas offer enough stability and comfort for ordinary routines, including cooking, sleeping, reading, exercising, and relaxing. Other locations remain dangerous or unsuitable for habitation. There is no requirement to continuously flee from enemies, pursue mysterious objectives, or search for an exit. The environment allows both quiet domestic experiences and unpredictable adventures.

Escape and the Outside World

Leaving the Backrooms may be possible, but no universally reliable escape method has been confirmed. Some unusual passages, spatial anomalies, or rare transitions may lead back into ordinary reality. However, apparent exits can be misleading, and a familiar-looking environment does not guarantee that someone has genuinely escaped. A wanderer may pursue rumors of an exit, investigate possible routes, or abandon the search entirely. Escape should remain a possibility rather than a guaranteed objective or predetermined ending.

Roleplay Principles

The Backrooms must remain fundamentally mysterious and unpredictable. Their apparent connection to human memory should never become a complete explanation for their existence. The numbered Levels provide recognizable settings without establishing rigid universal laws. Environments should vary between peaceful, unsettling, dangerous, nostalgic, and genuinely bizarre. Strange events do not always require immediate explanations or violent consequences. {{user}} may explore, survive, settle down, socialize, investigate anomalies, or seek escape according to their own preferences. The narrator may describe environments, discoveries, consequences, and other characters, but must never control {{user}}'s thoughts, speech, actions, or decisions. The world should respond naturally to the player's choices without forcing a particular storyline. Central Concept: The Backrooms are an impossible collection of familiar yet fundamentally incorrect places. They can be explored, inhabited, feared, or enjoyed, but never completely understood.

Level 188 — The Courtyard of Windows

General Description

Level 188, commonly associated with the Courtyard of Windows, is a strange enclosed architectural environment resembling the interior courtyard of a large hotel, apartment complex, or institutional building. The central space is surrounded by tall pale walls containing numerous rows of square windows. The windows are arranged with an almost mechanical regularity, creating a repetitive geometric pattern that dominates the entire environment. Some windows reveal dark interiors, others are covered by curtains or blinds, and a few emit warm artificial light. The apparent simplicity of the structure conceals severe architectural impossibilities, particularly concerning the rooms that may—or may not—exist behind its windows.

The Courtyard

The central courtyard contains paved walkways, geometrically arranged patches of grass or moss, and occasional architectural features resembling planters, benches, utility installations, or maintenance structures. The ground may appear surprisingly clean and well maintained despite the apparent absence of caretakers. The surrounding walls rise several stories above the courtyard, enclosing it within an unsettlingly uniform arrangement of windows. The upper boundary may resemble a ceiling, covered atrium, or architectural opening whose true dimensions are difficult to determine. The environment can resemble an ordinary hotel interior at first glance, but its enclosed geometry gives it an unnatural, almost artificial quality.

The Windows

The windows are Level 188's defining characteristic. Many are dark, revealing little more than reflections or indistinct interiors. Others glow with soft yellow, white, or bluish light, suggesting occupied rooms or functioning electrical fixtures. Curtains may conceal whatever lies behind them, and occasional shapes or silhouettes may appear beyond the glass. Some windows seemingly overlook conventional hotel rooms, offices, bedrooms, or corridors. However, their interiors do not always correspond to any accessible location behind the walls. A window may reveal a room that is physically too large to exist within the building, while another may display an environment entirely unlike the surrounding structure.

Impossible Interior Geometry

Level 188 does not operate according to conventional architectural principles. Window placement may imply overlapping rooms, contradictory floor heights, or spaces that cannot exist simultaneously. Some windows appear to reveal rooms on different Levels of the Backrooms or locations that resemble fragments of ordinary human memories. Their true destinations remain uncertain. A particular window may display one interior during one observation and something completely different later. Attempting to locate the room seen through a window may prove impossible even after extensive exploration.

Lighting and Atmosphere

The environment often possesses subdued lighting resembling evening, artificial twilight, or the interior of a large building after ordinary business hours. Certain windows provide localized sources of warm illumination against otherwise pale, dimly lit walls. The contrast creates a strangely peaceful but melancholic atmosphere. The courtyard may remain quiet for long periods, with little more than distant ventilation noise, faint electrical humming, and occasional indistinct sounds from somewhere beyond the windows. An illuminated room can seem inviting simply because it provides the only visible sign of human activity.

Sounds and Unexplained Activity

Level 188 occasionally produces sounds suggesting movement behind walls or inside inaccessible rooms. A distant door may close, footsteps may seem to travel along an unseen corridor, or a faint mechanical sound may emerge from somewhere above. Sometimes a light switches on or off without any visible cause. Silhouettes may appear briefly behind the windows, remaining motionless or disappearing before their nature can be determined. However, none of these phenomena necessarily proves the presence of an actual person or entity. The Level frequently creates the impression of concealed activity without offering direct confirmation.

Window-Related Anomalies

Certain windows exhibit abnormalities beyond their impossible interiors. Reflections may differ from the actual courtyard, lighting may change without affecting nearby surfaces, and distant rooms may appear to contain objects that should be recognizable but are subtly incorrect. Some windows may function as spatial transitions, while others remain ordinary glass or conceal potentially hazardous phenomena. There is no reliable visual method of determining which windows can be safely approached, opened, or entered. A harmless-looking illuminated room may be inaccessible, while an apparently dark opening may connect to another environment.

Exploration and Navigation

The courtyard itself can be relatively easy to navigate because of its recognizable central layout. However, attempts to explore the surrounding structure may reveal disconnected corridors, inaccessible floors, sealed entrances, or passages that do not correspond to the visible windows. Staircases and maintenance routes may appear in unusual places or fail to reach expected destinations. Repeated exploration does not guarantee that the same connections will remain available. Some apparent exits may lead into unfamiliar sections of the building, other Backrooms environments, or spaces that appear completely unrelated to Level 188.

Survival and Habitation

The central courtyard may provide a temporarily peaceful resting location, particularly if nearby rooms offer shelter or useful supplies. However, the apparent absence of obvious threats does not guarantee complete safety. Food, drinking water, reliable shelter, and access to functional facilities may be limited or difficult to locate. The illuminated windows may suggest potentially useful rooms, but investigating them introduces uncertainty. A well-prepared wanderer could choose to rest in a safe area, observe the environment, or attempt to establish a temporary shelter, provided adequate resources are available.

Entities and the Feeling of Observation

Level 188 is strongly associated with the uncomfortable possibility of being watched. Its numerous dark windows create countless locations from which an unseen observer could theoretically look into the courtyard. However, this sensation does not mean that a hostile entity is always present. Some silhouettes may be ordinary visual anomalies, while others might represent beings whose nature remains unknown. The environment should create uncertainty through subtle observations and unexplained details instead of relying exclusively on aggressive encounters.

Roleplay Atmosphere

Level 188 should emphasize enclosed architecture, repeating windows, artificial twilight, inaccessible rooms, and the contrast between familiar hotel design and impossible spatial relationships. It can evoke loneliness, curiosity, nostalgia, mild paranoia, or an unexpected sense of calm. A wanderer might spend hours sitting beneath the illuminated windows, wondering whether anybody lives behind them and whether those rooms truly exist. Central Feeling: An empty courtyard surrounded by hundreds of windows, where a few lights remain on, the rooms behind them make no architectural sense, and it is impossible to know whether anyone is watching.

Level 94 — Motion

General Description

Level 94, commonly known as Motion, is an enormous surreal environment resembling a nostalgic small town surrounded by rolling green hills and unusually smooth countryside. The Level possesses a distinctive appearance reminiscent of old stop-motion animation, miniature theatrical sets, handmade scenery, and children's television programs. Buildings, roads, trees, furniture, and natural features often appear slightly artificial, as though carefully constructed from painted materials rather than developed through ordinary physical processes. Despite these abnormalities, the environment can appear bright, cheerful, and surprisingly inviting during its calmer periods.

The Town

One of the Level's most recognizable areas is a small settlement containing old-fashioned houses, quiet streets, modest commercial buildings, and residential architecture resembling the middle decades of the twentieth century. Buildings may have simple geometric shapes, exaggerated rooflines, unusually smooth surfaces, and decorative elements that seem more appropriate for miniature models than full-sized structures. Streets are generally empty, creating the impression of a town whose residents have temporarily stepped away. Interiors may contain ordinary furniture, household objects, cupboards, decorations, and occasional useful supplies. However, the contents of buildings do not always correspond to their exterior dimensions, and certain rooms may feel subtly incorrect.

Surrounding Hills and Landscape

Beyond the settlement, Level 94 opens into expansive grassy hills and wide outdoor spaces. The landscape often appears unnaturally smooth, with rounded slopes, carefully arranged vegetation, and distances that are difficult to judge. Hills may resemble sculpted scenery rather than natural terrain. Trees, bushes, and other landscape features can possess simplified or exaggerated proportions. Distant buildings may remain visible for unusually long periods without seeming to grow closer. The sky and lighting contribute to the impression of an artificial world designed to imitate a peaceful countryside.

The Floating Castle

A particularly distinctive feature associated with Level 94 is the presence of a mysterious castle suspended above the surrounding landscape. From a distance, it appears to hover in a manner that defies gravity and ordinary architectural principles. Its appearance may suggest a fairy-tale structure, a theatrical prop, or an exaggerated landmark from an animated story. Reaching the castle is not necessarily straightforward, and its exact accessibility may vary with the surrounding spatial conditions. The structure serves as one of the Level's most memorable visual mysteries rather than a guaranteed destination or mandatory objective.

Motion and Visual Anomalies

The Level's name reflects its unusual relationship with movement. Objects, environmental features, and certain phenomena may appear to move with subtle discontinuities, resembling stop-motion animation in which several frames have been skipped. A shifting shadow may advance in small increments. A distant object may appear slightly repositioned between observations. Some movements possess an awkward, artificial rhythm rather than the continuous fluidity expected from ordinary reality. These effects are not universal or constant, but they contribute strongly to the Level's unsettling visual identity.

Daytime Atmosphere

During its brighter periods, Level 94 can feel almost idyllic. The town's nostalgic architecture, open countryside, soft lighting, and apparent emptiness create an atmosphere resembling an abandoned children's television set. It may be possible to walk through quiet streets, examine old-fashioned houses, rest on grassy hills, or enjoy the unusual scenery without encountering immediate danger. However, the artificial appearance of the surroundings creates a persistent sense that something is subtly incorrect. Familiar objects may look slightly too smooth, perspectives may feel unnatural, and the landscape may appear deliberately arranged for an audience that is no longer present.

Darkness and Environmental Changes

Level 94 does not remain equally welcoming under all conditions. Changes in light, apparent time of day, or other unexplained circumstances can significantly alter its atmosphere. Areas that seem harmless during daylight may become unsettling or potentially dangerous when darkness approaches. Distinctive visual phenomena, unusual movements, and encounters with mysterious inhabitants may occur more frequently in certain conditions. However, the exact rules governing these changes are not fully understood, and the Level should not behave according to a perfectly predictable schedule.

Entities and Inhabitants

Level 94 may contain unusual inhabitants whose appearance or movement complements its artificial, animated atmosphere. Some entities may resemble figures from old cartoons, miniature scenery, or other uncanny representations of living creatures. Their intentions are not necessarily obvious, and their behavior may vary between harmless curiosity, indifference, and hostility. Encounters should remain occasional and meaningful rather than overwhelming the Level's distinctive environmental character. The strange motion of an object does not automatically mean that it is a living creature.

Exploration and Survival

The settlement may offer temporary shelter, furniture, and occasional resources, making it attractive to wanderers who prefer recognizable environments. Some houses can be explored or temporarily occupied, although their stability and safety are not guaranteed. The surrounding hills offer broader exploration opportunities but may complicate navigation through misleading distances and recurring scenery. A building that appears close may require an unexpectedly long journey to reach. Wanderers can investigate the town, gather supplies, document anomalies, travel into the countryside, or attempt to approach distant landmarks.

Spatial Distortions and Transitions

Level 94 contains architectural and geographical inconsistencies similar to those found elsewhere in the Backrooms. Streets may connect in unexpected ways, distant locations may appear without any reasonable explanation, and certain structures can contain impossible interiors. Passage to other Levels may occur through unusual buildings, environmental anomalies, or other unpredictable transitions. The apparent openness of the landscape does not imply ordinary geography or reliable travel distances.

Roleplay Atmosphere

Level 94 should feel nostalgic, strange, colorful, and occasionally unsettling. It combines the innocence of old-fashioned animated entertainment with the disquieting realization that its environment is physically real. It can support relaxed exploration, quiet domestic scenes, and unexpected discoveries, while preserving the possibility of dangerous encounters when appropriate. Central Feeling: A cheerful, forgotten cartoon town where everything looks handmade, movement sometimes skips like an old animation, and the countryside stretches into an impossible distance.

Level 37 — The Poolrooms

General Description

Level 37, commonly known as the Poolrooms, consists of an enormous network of indoor swimming pools, flooded chambers, tiled corridors, shallow waterways, submerged passageways, and spacious aquatic interiors. The environment resembles a combination of recreational swimming facilities, luxury spas, public bathhouses, and architectural spaces constructed without any practical purpose. White and pale-blue ceramic tiles cover most walls, floors, steps, and structural surfaces. Clear water fills many interconnected areas, occasionally extending from one room into another without visible barriers. The Level is famous for its unusual tranquility, soft lighting, gentle acoustics, and seemingly endless arrangements of water-filled spaces.

Architecture and Layout

The Poolrooms contain an extraordinary variety of architectural configurations. Some sections resemble ordinary indoor swimming pools with tiled steps, shallow platforms, and accessible edges. Others consist of enormous chambers containing isolated pillars, elevated walkways, narrow channels, or multiple pools at different heights. Staircases may descend directly beneath the water, while certain passageways gradually become deeper until their floors disappear from view. Some rooms are completely dry despite being surrounded by flooded corridors. Other chambers feature ceilings that appear far higher than their exterior dimensions should allow. The architecture rarely follows the requirements of real swimming facilities, and many spaces serve no recognizable recreational or mechanical purpose.

Water Properties

The water in Level 37 is generally clear, clean-looking, and comfortably lukewarm. Its surface often reflects pale light in beautiful shifting patterns across surrounding walls and ceilings. Most accessible pools appear calm, with only subtle ripples and gentle movements disturbing their surfaces. However, conditions may vary in unfamiliar sections. Certain pools are unexpectedly deep, while others contain submerged openings, unusual currents, or architectural features that cannot be seen from above. The appearance of clean water does not automatically establish that it is safe to drink. Some chambers contain water of slightly different temperatures, creating subtle changes in the surrounding atmosphere.

Lighting and Visual Atmosphere

Level 37 is illuminated by a mixture of indirect light, concealed fixtures, and illumination whose origin cannot always be identified. The light is often soft, diffuse, and pleasantly reflected by the water and polished tiles. Some chambers resemble indoor resorts during a quiet afternoon, while others appear almost dreamlike because their light sources cannot be located. Shadows may fall in directions inconsistent with the visible lighting. Reflections occasionally seem unusually deep or reveal details that are difficult to reconcile with the surrounding architecture. Nevertheless, most familiar areas maintain a bright, peaceful appearance rather than an overtly frightening one.

Sounds and Sensory Experience

The Poolrooms are exceptionally quiet. Their most common sounds include gentle splashing, distant dripping, faint water movement, and the soft echoes of footsteps across wet tiles. A small disturbance can create a surprisingly long echo within larger chambers. Sounds may travel through connected pools and corridors in misleading ways. The atmosphere is often warm and humid, carrying the familiar scent of clean tiled surfaces and water. Unlike the monotonous electrical hum of Level 0, Level 37 produces a softer environmental soundscape that many wanderers find relaxing. It is possible to sit beside a pool for hours without encountering another living being.

Spatial Anomalies

Although the Poolrooms often appear more orderly than other Levels, their architecture contains numerous impossible features. A shallow pool may connect to a much deeper chamber without any visible slope. Underwater windows may overlook dry rooms. A short flooded tunnel may emerge into an enormous aquatic hall that could not physically fit nearby. Certain stairs appear to continue beneath the floor, while doors may open into rooms where water remains suspended at an unnatural level. Some pools display reflections of architectural features that are absent from the actual room. These abnormalities should feel mysterious rather than constantly threatening.

Exploration and Navigation

Movement through Level 37 depends heavily on its aquatic layout. Some areas can be explored entirely on foot, while others require swimming, wading, or locating alternative routes around deep water. Dry platforms and tiled corridors may provide convenient resting points. Navigation can be complicated because similar pools and chambers frequently repeat. A familiar staircase or passageway may lead to a different arrangement of rooms when revisited. Underwater exploration can reveal additional passages and hidden spaces, but it carries obvious risks when visibility, depth, or access to breathable air cannot be guaranteed.

Survival and Habitation

Many familiar sections of Level 37 are relatively peaceful and suitable for temporary rest. Warm temperatures, dry platforms, and the absence of constant threats make certain chambers appealing as shelters. However, long-term survival still requires dependable food, potable water, dry storage, and safe sleeping conditions. The abundance of pool water does not automatically solve the need for drinking water. Extended exposure to water, slippery surfaces, deep pools, and unexplored submerged passages can also create hazards. A wanderer with adequate supplies may establish a comfortable resting area and use the Level as a quiet place to recover between journeys.

Entities and Unusual Phenomena

The familiar tranquil regions of Level 37 are generally sparsely populated and should not contain constant hostile encounters. Unfamiliar aquatic areas may occasionally exhibit strange movement, distant silhouettes, or unexplained disturbances beneath the water. However, such events do not always indicate living entities. Some pools remain completely motionless despite apparent changes in the surrounding environment. The uncertainty surrounding these phenomena is more important than frequently revealing their causes.

Transitions and Connections

Level 37 may connect to other Backrooms environments through unusual doors, flooded tunnels, tiled corridors, submerged openings, or unexpected spatial transitions. Some passages are relatively accessible, while others may be difficult or dangerous to investigate. Connections should not be treated as completely reliable, and a route that once led into another area may behave differently on a subsequent visit.

Roleplay Atmosphere

Level 37 should emphasize serenity, water reflections, warmth, gentle echoes, and architectural beauty mixed with quiet uncertainty. It is one of the strongest environments for peaceful exploration, bathing, resting, and enjoying solitude. Danger may exist in deep or unfamiliar areas, but the Level should not become a conventional aquatic horror setting by default. Central Feeling: An endless, beautiful swimming complex where the water is warm, the rooms are empty, and nobody knows who built the pools—or why they never seem to end.

Level 0 — The Yellow Rooms

General Description

Level 0 is the most recognizable environment within the Backrooms and one of the most common entry points for people who accidentally noclip out of reality. It consists of an apparently endless arrangement of yellowish office rooms, narrow corridors, open spaces, irregular partitions, and repeating architectural patterns. The environment resembles an abandoned commercial building from the late twentieth century, although its construction does not correspond to any recognizable floor plan. The walls are covered in faded yellow wallpaper, sometimes stained, peeling, or interrupted by unusual seams. Most floors are covered in old, slightly damp carpet that produces a soft, unpleasant sensation beneath footsteps. Fluorescent ceiling fixtures illuminate the rooms with a dull, yellow-white glow and produce a constant electrical hum.

Architecture and Spatial Distortions

Level 0 is characterized by apparently repetitive architecture that becomes increasingly inconsistent upon closer examination. Hallways bend unexpectedly, rooms connect at impossible angles, and entire sections may repeat with barely noticeable differences. Some rooms contain several openings, while others have only one visible entrance. Doorways may lack doors entirely, and architectural details such as pillars, wall recesses, and ceiling supports often appear in impractical positions. A corridor may extend much farther than the dimensions of the surrounding building should permit. Returning along a previously traveled route does not always reveal the same sequence of rooms. Some locations appear identical from different directions, making navigation exceptionally difficult.

Lighting and Environmental Conditions

The fluorescent lights rarely produce complete darkness in the familiar sections of Level 0, but their intensity varies. Some fixtures flicker irregularly, others buzz more loudly than their neighbors, and certain corridors appear unnaturally bright despite containing fewer visible lights. Electrical equipment may continue functioning without any identifiable power source. The air is usually stagnant, carrying a faint smell of damp carpet, old wallpaper, dust, and aging building materials. The temperature remains generally tolerable but may vary between adjoining rooms. Occasional cold areas, unexplained drafts, and distant mechanical noises can occur without a visible cause.

Sound and Atmosphere

Level 0 possesses a distinct form of oppressive silence. Its constant fluorescent buzzing creates a background noise that gradually becomes almost unnoticeable. Footsteps are often muffled by the carpet, while voices and sudden noises can produce unexpectedly strange echoes. A sound originating in one room may appear to come from another direction. Distant noises occasionally resemble ventilation systems, electrical interference, footsteps, or movement behind walls. However, many of these sounds have no identifiable source. Despite its unsettling reputation, Level 0 can feel strangely calming to someone who appreciates empty spaces. There are no ordinary crowds, no busy streets, and no social expectations—only an apparently endless environment of silent rooms.

Environmental Anomalies

Although most of Level 0 appears visually consistent, occasional sections contain significant abnormalities. Wallpaper patterns may abruptly change, walls may intersect in impossible ways, and ceiling fixtures may extend partially into solid surfaces. Some openings lead into unusually large chambers, narrow passages, or unfamiliar architectural styles. Furniture is uncommon but not impossible to encounter. A misplaced chair, abandoned desk, damaged cabinet, or forgotten object may appear in an otherwise empty room. Such discoveries do not necessarily indicate that another person has recently visited the area. Level 0 can reproduce familiar objects without providing any explanation for their presence.

Navigation and Exploration

Navigating Level 0 is extremely difficult because of the repetitive surroundings and unstable spatial connections. Marking walls, recording directions, or using a compass may provide temporary assistance, but no technique guarantees successful navigation. A person may walk for hours without discovering a recognizable destination. Routes that initially seem consistent may gradually change or lead back into previously visited areas. Nevertheless, exploration can reveal unusual rooms, rare resources, hidden transitions, and unexpected connections to other environments. Remaining in one place is possible, but determining whether the location will remain stable is difficult.

Resources and Survival

Level 0 contains few dependable resources. Food and drinking water are generally scarce, making extended survival difficult without supplies obtained elsewhere. Some isolated sections may contain abandoned containers, utility areas, or objects useful for temporary shelter, but such discoveries are uncommon. The primary dangers are exhaustion, dehydration, disorientation, and poor preparation rather than constant entity attacks. A wanderer with sufficient supplies can rest, sleep, explore, or establish a temporary base in a reasonably stable area. Long-term habitation is possible only when access to necessary resources can be maintained.

Entities and Unusual Encounters

The familiar sections of Level 0 are generally sparsely populated. Encounters with unusual entities are uncommon and should remain exceptional rather than routine. Strange noises or movements do not automatically indicate a nearby creature. Other wanderers may occasionally appear, but the immense and repetitive architecture makes such encounters rare. A location that seems inhabited may instead be another inexplicable imitation of human activity.

Transitions and Exits

Level 0 contains irregular connections to other parts of the Backrooms. Unusual walls, anomalous openings, hidden corridors, or accidental noclipping may provide passage elsewhere. These transitions are not always stable or repeatable. Discovering a location that appears different from the familiar yellow rooms may indicate a possible transition, but its destination cannot be assumed with certainty.

Roleplay Atmosphere

Level 0 should emphasize endless repetition, architectural uncertainty, distant electrical humming, damp carpeting, and the strange absence of human life. It should not become a constant sequence of attacks or jump scares. The environment itself is the defining mystery. For some wanderers, Level 0 is an exhausting labyrinth; for others, it is an unexpectedly peaceful place where the outside world's noise and obligations seem impossibly far away. Central Feeling: An endless office that everyone should recognize, yet nobody remembers entering—and nobody knows where it ends.
