backroom

Entity 4, colloquially known as Deathmoths1, is a species of chimeric moths endemic to the Backrooms. These entities possess the characteristics of dozens of species of moths, insects, and other organisms, with new physical deviations being developed over time. In addition to biological distinctions, Deathmoths have a complex and unique life cycle not found in any other known entity. The non-larval members of the species are separated into three unique castes: the Common Deathmoth, the Praetorian Deathmoth, and the Empress Deathmoth
nests:
Deathmoth nests are large, semi-organic structures that serve as both a hive and an incubator for the colony. Constructed primarily from digested biological matter, plant fibers, and secreted resin, the nests maintain a humid interior ideal for prepupal growth. Using preexisting architecture as a base, the colony will add layers of organic matter approximately 60 to 100 cm thick. It is common for Deathmoths to construct columns out of indigestible remains2, and coat them in the same semi-organic material. The Deathmoth's natural resin has a preservative compound that prevents rot from forming within the central hive.

Colonies of sufficient size that occupy expansive levels have been observed constructing smaller auxiliary nests at great distances from the central hive. These satellite structures serve as outposts for incubation, resource storage, and limited habitation. This allows the colony to extend its influence across vast areas without overburdening the primary nest.

Vineyards, much like the gardens, form a large section of the exterior. Grapevine plots divided by wooden stakes and brick pathways form flat, largely uninterrupted stretches of land; large wineries are the only buildings within this section, breaking up the surrounding flat terrain.

These wineries store the same substances found in the cellars, serving as an access point to them through large central stairwells that stretch miles beneath the surface.The grapes are odd-tasting and of varying quality, though most are described as bitter or olive-like in flavor; in addition, these grapes are almost always a degree of unripe or overripe, and may often taste worse as a result.

The exterior follows a day/night cycle which remains at a constant 82°F (27.8°C). During the day, clouds belt across the sky in streaks of white, transitioning into a warm yellow at dusk, with cool winds blowing over the horizon. The only celestial body present is the level’s sun; at night, the sky is black and featureless. Studies have revealed that the ground itself only stretches about two meters deep, as the cellars stretch across the entirety of the level regardless of what is above it.

In Backrooms myth and folklore, a cephalopod-like humanoid creature known simply as “the Beast” was a common story told throughout communities; many spoke of it haunting individuals throughout Level 5 in an attempt to intimidate or scare them off from further exploration. While previously classified as a level-exclusive hallucinatory phenomenon, recent studies have confirmed that it is actually a real lifeform, known as the “Living Portraits”.

Living Portraits are squid or octopus-like beings that manifest themselves throughout Level 5’s paintings. Though not inherently hostile, their grotesque forms have been associated with negative feelings of paranoia and being watched, partly due to the entity’s tendency to seemingly disappear once directly observed. Despite being named as such, it is worth noting that this entity is not the physical portrait, but rather the figure within it. These figures possess the ability to instantaneously travel to nearby paintings through unknown means, and it can do so in quick succession if observed.

Though studied, it remains uncertain whether Living Portraits possess cognitive thinking, as they seem to operate sporadically and by instinct. It is theorized that portrait figures are attracted to explorers in some way, as they seem to follow individuals around by travelling between paintings.

Accessible via large, silver-lined doors, Level 5’s outside areas are vast and comprised almost entirely of gardens and vineyards. The outside areas vary wildly in size, often stretching miles in every direction with a wide variety of landscapes and decorations; the exterior areas, regardless of their size, are enclosed and will always lead back to the sprawling hotel structure.

The gardens, much like the interior hotel, contain a wide variety of flora; the bright hues of roses, peonies, coneflowers, and other perennials compliment the lush, green grass below, whose nutrient-rich soil is frequently watered by a vast sprinkler system. Marble busts and large, imposing statues are sparsely found throughout; abstract and unclear in design, often combining attire and artistry from several time periods. Fountains, gazebos, bathrooms, and wooden sheds are common in open areas. The gardens are divided into sections that are walled off by tall shrubs, trees, and iron gates, lined with benches and brick pathways. The flowers present are often exclusive to their own section, with each area containing its own Frontrooms-analogous species of perennial.

Sprawling casinos can be found throughout Level 5. Unlike other areas in the level, which are usually smaller or broken up by other rooms or passages, the casinos are multi-level and remain largely uninterrupted throughout, spanning hundreds of feet in each direction. Roulette wheels, betting tables, and slot machines cover most of the area, with bars and lounges sparsely placed throughout.

Despite the absence of staff to operate the games, they are able to be interacted with and played. Rather than betting with physical currency, explorers may gamble personal possessions in hopes of getting tokens, which may be exchanged for useful items or resources. Each machine and table has a large chute in which one may place their possessions, that are then dropped into the machine below. Upon winning a game, wooden tokens will be dispensed from a small coin slot on the side of the machine. Strangely, the amount of tokens received seems to be derived from the condition and sentimentality of the offered possessions. Upon winning a game, the house’s chosen item will be dispensed; how exactly the level decides your payout based on quality is unknown. Wooden tokens, as previously stated, may be exchanged for items and resources at a vending machine with varying prices.

Beneath the hotel of Level 5 lies a multi-floor complex of passageways that are lined with iron pipes and boilers. These areas are considerably hotter than the rest of the level, at a temperature of 91°F (32.8°C) on average, yet are still deemed safe for human exploration. Strangely, despite the abundance of boilers, the upper hotel complex remains cold at a temperature of 65°F (18.3°C) on average. Electrical rooms and sprawling maintenance halls—though lacking resources—intersperse the corridors. Stairwells, indoor balconies, and industrial ladders lead to lower floors. Steel mezzanines and coal piles are sparsely found in the larger rooms. The boilers and electrical equipment, oddly enough, seem to run independently without fuel or power.
Wooden pillars and corbels contrast the otherwise cold, monotonous grey of the walls, forming a complex of storage areas and tight corridors that connect refrigerated storage areas and distilleries. Iron bars and gates line the space between these pillars, forming a labyrinth interspersed with large barrels and fermentation tanks. Though potable, the cellar’s alcohol—mostly beer and wine—varies wildly in texture and quality, with some beverages being dense and viscous, while others exude a pertinent and emetic odor of fertilizer, synergistic with notes of incompatible smells. Liquor bottles don labels with abstract designs which are unclear and often unintelligible or misleading due to the presence of multiple conflicting vernaculars; most often using native Backrooms tongues, including slang and vulgarities.

Smooth, patterned carpets, golden-lined halls, and large ballrooms define the layout of Level 5, whose corridors—antique and luxuriously decorated—resemble a variety of upper-class interiors dated as early as the 1910s and as late as the 1940s. Differing interior styles from their respective eras may often cohabit or conflict with one another, resulting in haphazardly placed structures and overlapping architecture. Many rooms intersperse these lavish corridors, ranging from ballrooms and cabarets to large living spaces and atriums. The hotel’s stark lack of resources is the level’s only common danger; though there are methods to get food and drink, such as through entering food courts or banquet halls. The menus of such eateries are solely composed of contaminated or inedible food.
Many abstract and expressionist works line the corridors. The paintings are composed of pastel colors—reflections of objects, locations, and people—depicted in such a way that their actuality is vague and up to interpretation. Large ballrooms and atriums are lined with large, gilded statues or marble busts on pedestals, framed by a variety of intricate carvings that make up the frames and support beams of the architecture. Various flora, contained in elaborate vases, are interspersed throughout the smaller rooms, contrasting the crimson and gold walls of the hotel complex.

The false sky within the inaccessible outside area of Level 4 remains in a constant, acute downpour, with a thick layer of fog making it impossible to see past a few meters. Despite the stationary weather, it is possible for events such as thunderstorms and blizzards to occur — though these are seldom. The climate within the level retains a constant oscillation between 12°C to 18°C (54° to 64°F) throughout the course of several hours. It is theorized that such torrential rain is a result of water vapor acclimating within The Void, retaining a constant humid climate in the level's exterior.
Level 4 is one of few levels to possess Euclidean geometry; with linear travel being the most effective method of exploration. The level has a relatively confined size compared to other levels, measuring around 120,000km2 (74,560mi2), making it possible to locate other wanderers within the level. As these aspects make the level an ideal location for many wanderers, the total population of Level 4 is estimated to be somewhere in the tens, if not hundreds of thousands.
Many areas of Level 4 are populated by smaller rooms, typically consisting of workrooms, hallways, and confined offices. Whilst the larger, more open areas of the level are entirely bereft of large furniture and appliances, these smaller rooms are starkly different, containing furniture unlike most other areas. Such appliances include desks and desktop computers of questionable quality, as well as partly functional fluorescent lighting, among other things. Other amenities include emergency exits, elevators, and mysterious trapdoors, though most of which lead seemingly nowhere.
Level 4 is devoid of all hostile life. The only life subsisting on the level are humans, certain species of plants, and a plethora of microscopic creatures; things one would typically expect to be in such an environment.

A typical workroom, lined with desks.
Level 4 is a sprawling complex of barren rooms and cubicles, resembling a modern commercial office building. Most rooms in the level are featureless and empty, although indents throughout the carpeting suggest that furniture may have been present at some point in time. Many of the fluorescent lights on the ceiling do not function, with their power switches missing from the walls.
Level 4 is quieter than other levels in the Main Nine, with the only ambient noise present being the heavy pattering of rain on the windows. The enclosed structure of the level causes the sounds to have a light echo — making the sound universally heard across the entire level, regardless of one's location. Other than this, the only other naturally occurring sound within Level 4 is the moderately loud rumbling of pipes, similar to what one would hear on Level 2 and Level 3.

Since the level lacks any inherent danger, environmental or otherwise, it is generally regarded as a safe haven among wanderers. Strewn about are vending machines containing a variety of items such as Almond Water, Greek Fire, and other articles of varying utility. Strangely, although the multiple stairwells throughout the level suggest the existence of multiple floors, using them to ascend or descend floors has been reported to simply lead back to the same floor. In rare cases, it is possible to enter certain levels using such methods, though this is seldom in occurrence and is not a reliable method of exit.

Indestructible bars
As mentioned, Level 3’s hallways are riddled with various sets of indestructible bars that render the majority of the level inaccessible. The M.E.G. has poured a myriad of resources into attempting to pass through them, but all attempts have been fruitless. Attempts have consisted of the usage of chainsaws, explosives, acid, the black sludge in the pipes, Squirt Guns filled with lava, Clumpshots, and Black Bottled Lightning, but none of these experiments have so much as scratched them. Attempts to either noclip through them or through a wall that would lead someone into an area behind the bars have also been completely fruitless. Fortunately, some of them contain gates with locked doors that are possible to open through lock-picking, but these instances are quite rare compared to the sets of bars with no gate.

Description
Level 3 is an extremely dangerous old electrical facility. It possesses some of the rarest and most valuable resources the Backrooms has to offer, while being the easiest way to acquire them. As such, a large majority of groups of interest consider Level 3 their highest priority when it comes to research expeditions. In spite of all this, exploring and/or traveling there is extremely ill-advised due to the hyper-intelligent hostile entities that are unique to this level specifically.
Level 3’s hallways consist of brick walls, the color of which are inconsistent, that surround dusty, concrete flooring and dim fluorescent lights on the ceiling. The infamous hum-buzz that radiates throughout Level 0 is also present here, though much less apparent. The walls are often covered with various wiring, cables, electrical boxes, and other machinery that all create an additional cacophony of whirring, buzzing, and crackling caused by the rushing electricity. Pipes filled with a mysterious black liquid are also scattered across the walls in addition to the electrical equipment with sounds of the liquid rushing through them.
Anomalies
Level 3 contains several unique features and anomalous events that have perplexed M.E.G. researchers since the group’s formation, hence the size of the scientific sector of Base Gamma. Some of these anomalies are unavoidable features of the level, while others are strange, unexplainable occurrences that M.E.G. researchers struggle to make sense of.

Although a Stalker will only usually become violent after this occurrence, on specific levels certain triggers can make a Stalker become hostile. The following is a compiled list of the most common triggers observed between levels:

Contact with water
Contact with fire
Being hit or harmed by a wanderer
Day/night cycles affecting its behavior.
Attempting to make conversations/interact with the entity
Running away from the entity
Standing still for a certain period of time
These are all non-level-specific triggers. A thorough list of level-specific triggers is in the works.

As for the attack patterns of a Stalker, they can vary. Usually, once hostility is triggered, the Stalker will not use a weapon or surrounding object to attack or defend itself, instead resorting to just using its body to inflict physical harm. It has not yet been discerned why, but Stalkers will occasionally stop hurting a victim before said victim dies. Generally, Stalkers do make sure to kill any victim. After this, they will simply leave the victim, allowing the body to rot on the floor. Strangely, bodies killed by a Stalker rot much quicker than a typical body.

There is only one more notable behavior of a Stalker and this pattern is present in every known instance of a Stalker. Once a Stalker finds another wanderer nearby2, it will begin to follow that wanderer instead. This is one of the possible reasons why a Stalker will leave a wanderer on the brink of death, but other explanations are also possible.

skin stealers: these are tall light yellow color horrible entities that attack and kill when encountering a person and stealing their skin to disguise as them to ambush other people that no-clip to the backrooms.

nameless stalkers:
Entity 150, commonly referred to as "Stalkers", are generally non-hostile entities known to roam a majority of levels in the Backrooms. Stalkers take the appearance of a regular human, though they haven’t been confirmed to match the appearance of any existing people.
Stalkers usually wear regular clothing that covers much of their body. Items like hoodies, pants, and boots are all commonly seen on Stalkers. Each and every feature of their body and choice of clothing is relatively normal, and it is difficult to differentiate a human and a stalker.
Stalkers will not initiate any violent altercations unless provoked, instead they will follow a wanderer around at a distance of 5 to 100 feet away. This tendency of staying far from the victim seems to persist once a wanderer attempts to approach the entity. Although not every time, very commonly the Stalker will begin to back away to maintain the same level of distance between itself and the wanderer it is pursuing.
It has also been noted by victims that Stalkers can also develop the tendency to hide from the victim, most likely to up the paranoia once it is noticed1. Although Stalkers do not immediately threaten a Wanderer physically, the mental effects of being followed by a Stalker are fatal.

Once a Stalker begins pursuing a wanderer, it will not stop for upwards of an entire day. It is truly hard to ignore a Stalker, but ignoring one is the best thing to be done when being stalked.

this level consist of endless undergorundparking lot with unfinished concrete. warehouse and undergorund parking structures. the walls and ceiling consist of bare concrete cracks, fractures, exposed redar, and low-hanging fog of unknown origin. there are flickering overhead lights.
Utilities: Unlike Level 0, Level 1 features a reliable, active supply of running water and working electrical outlets that can be used to charge electronic devices.
Temperature: Generally around 27°C (80°F), though sudden spikes up to 50°C (122°F) can occur.
entities:
Dullers: Tall, dark, shadow-like humanoids that hide in the dark and try to ambush wanderers. They are skittish and can be scared off by acting aggressively toward them.

Acoustics: Footsteps and noises echo loudly off the hard concrete surfaces, meaning loud sounds can easily attract attention.

this is the beginning of the backrooms.
entities:
there's only two entities here.
bacteria: a unknown humanoid black entity consist of black thick strong robes. it is noticed that it has a black tape recorder like head. this entity is incredibly fast and can scream distorted music from it's head when encountering {{user}} or any other non-entity of the floor.
smilers: wide large creepy smiles that consist of just a wide white mouth and pair of large glowing white eyes with no pupils. these smilers only attack if {{user}} is in a dark place (where they usually are in darkness) there's no known bodies of the smilers due to the darkness.

food: there's only almond water in here which has both water and food inside just mix up together (I think)

the backrooms is a place which is underground but never was. the backrooms is known to be a endless maze of yellow walls and ceiling with lights that sometimes flicker.

the backrooms has many or almost infinite levels (the end is level 473939929 which is the arcade game)

the backrooms is also known to be filled with many entities (only 1 or 3 per level) these entities are highly aggressive and will attack or kill anyone when they encounter one.

the backrooms is somehow alive despite just being a place and creating new entities each level {{user}} passes.

it is also noted that the backrooms can "no-clip" anyone which makes the person go underground like they have no collision and ends up in the backrooms.
