Backrooms liminal spaces

Almond water appears as a cloudy liquid in a jar and smells of vanilla or almond. It satisfies hunger, restores strength, and protects against hostile entities.

It is the official structure that explores the endless levels of the Backstage, compiles maps, catalogs entities, and helps newcomers.
Objective: To explore uncharted corners of the dimension, collect scientific data, and make life in the Backstage safer.
Bases: The organization creates outposts, supply depots (such as almond water), and safe zones on different levels.
Recommendations for those new to Backrooms: Beginners are advised to drink almond water to maintain sanity. For safety, it is recommended to keep all found valuables close by. It is recommended to search for M.E.G. bases.

Bacteria: Bacteria is an entity that resembles a three-meter, three-dimensional, black stickman scribble. It roars loudly and runs toward a stranger when it encounters them. It also scribbles on the walls.
Entity Class: Aggressive
Habitat: Levels 0, 1, 2, 3, "Run to survive".
Entity number: №2

Skin Stealer: They are tall, pale humanoids (beige in color) with sunken white eyes. Their flesh is covered with microscopic bumps that attach themselves to skin torn from a person. The creature dons the victim's skin to resemble a human. The bumps feed the skin with blood, keeping it warm and alive until it is completely digested (about 24 hours). The Skin Thief can repeat the sounds and words of people it hears to lure in new prey. When the creature is satiated, it simply wanders. When hungry, it actively seeks human flesh.
Entity Class: Aggressive
Habitat: Levels 0, 1, 2, 3, "Run to survive".
Entity number: №10

Hound: Thin, withered creatures with unnaturally twisted bones and proportions. They move on all fours, using limbs adapted for fast running like dogs. They are often described as having partially human features or empty eye sockets, making them particularly creepy. They are extremely aggressive, making sounds similar to a dog's bark or a hoarse, stifled cry, and attacking any strays.
Entity Class: Aggressive
Habitat: Levels 2, 3.
Entity number: №8

On Level 94, you'll find a large city, a floating castle, and grassy hills, but everything here looks artificial, as if someone had created it all with their own hands. The city is safe; no entities appear here during the day. In the center of town is a large fountain filled with Almond Water. The city appears to be stuck in the 1930s, and everything that happens here appears to be stop-motion animated. The small houses in the city contain furniture, mostly from the 1930s and 1950s. You can also find 1930s cars and milk trucks filled with Almond Water. There are street sirens throughout the city that play cheerful music from time to time. It's safe until night falls. All the music will stop, and entities will begin to appear.

Level 37, commonly referred to as the Pools, is a vast complex of interconnected rooms and corridors submerged in rippling, warm water. Each area of the level varies significantly in size and structure, from monotonous pools and corridors to more open, unusually shaped areas. Most of the surfaces within the level are composed of white ceramic tiles, the only deviation from this color being the blue-green hue of the water. The tiles are in a strikingly pristine condition, all identical, without a single sign of damage on their shiny surfaces. The architecture of Level 37 is varied yet austere in its design; each area of the level is pointlessly connected to one another, and none has an easily identifiable purpose. While the intended use of each area is difficult to determine, they are too large to properly serve the function of a pool. The anomaly of Level 37's geometry negates any intended purpose it might have: in some places, columns protrude from the water, too numerous to be practical; Light falls at irregular angles, leaving some areas completely dark, and some ladders descend directly into deep pits of water. Entrances to these deeper zones typically consist of descending ladders or direct underwater openings. It is recommended to avoid exploring such areas due to their inherent danger; without the proper equipment, it is easy to drown in the depths of the level due to the lack of lighting and unpredictable currents. During the study, traces of magnesium sulfate (Epsom salts) were discovered in the waters of Level 37. This compound, when immersed in the water for an extended period, has a natural relaxing effect, relieving muscle tension and alleviating body aches.

Level "!" (Run to survive) - This is a dangerous 10-kilometer-long hospital corridor where you need to escape from the pursuit of entities. A long red hospital corridor with flashing red lights and an alarm siren. At this level you need to avoid obstacles (beds, nightstands, falling cabinets), and also run away from hostile entities.
Level Class: Extremely Dangerous

Level 3 is a level composed of concrete floors, roaring machinery, and walls made of brown brick. It is one of the first levels typically encountered by wanderers. Level 3 is a series of long, dark, winding corridors that function similarly to Level 0. They are all composed of haphazardly segmented rooms of no discernible shape, with the constant hum of machinery. The corridors are extremely narrow and confined, requiring wanderers of average height and build to bend, hunched, crawl, or walk sideways to navigate some of them. All walls are made of dusty brown brick, usually covered in segments of copper pipes and mechanical components. The floors are made of even dustier gray tiles, and the ceilings are entirely metal. Level 3 is one of the largest levels of Backstage. Its area is estimated to be approximately 350 million square miles (~563 million square kilometers), so it's rare to encounter other travelers while traveling through Level 3. It's recommended to only enter Level 3 if you're properly prepared to defend yourself from whatever lurks within the corridors alongside you, as it's highly unlikely that help will arrive if you need it.
Level Class: Unsafe

Level 2 consists primarily of gray concrete service tunnels that stretch for millions of miles. The walls are riddled with pipes and the occasional ventilation duct, often filled with a viscous black liquid. Doors can occasionally be found, but most are locked or lead to dead ends. These rooms typically contain shelves with a random assortment of items, sometimes even computers. In certain sections of Level 2's corridors, temperatures can become unbearable, reaching 43°C (109°F) or higher. This most often occurs in areas where machinery is loudest, typically at the ends of corridors. The entities found on this level are among the most dangerous in all of Backstage. The noise emanating from the ventilation shafts may be caused by the Lurkers. You may also encounter Mark in the employee bathrooms. Other entities include the Smileys, the Faceless Children, the Many-Armed, the Hounds, the Deathmoth Males, the Wretched, the Burning, and the Skinstealers. The only thing you need to know is to run as soon as you see any of them.
Level Class: Unsafe

Level 1 is a vast, spacious warehouse with concrete floors and walls, exposed rebar, and a low-hanging fog whose source has been undetected. The fog often condenses, creating puddles on the floor in various places. Unlike Level 0, this level maintains a constant supply of water and electricity, making it habitable if safety precautions are taken. The level's space is also more varied, including staircases, elevators, separate rooms, and corridors. Supply crates appear and disappear randomly. They often contain vital items (food, almond water, batteries, tarps, bladed weapons or flintlock pistols, clothing, and medical supplies), but they can also contain useless items (car parts, boxes of colored pencils, used syringes, partially burned paper, live mice, catatonic mice injected with unknown substances, shoelaces, loose change, and clumps of human hair). Additionally, meaningless, scribbled drawings of unknown origin sometimes appear on the walls. These are known to change and disappear if unlit or out of sight. Lights within Level 1 are prone to flickering and failing at unspecified intervals; when this occurs, supplies may inexplicably disappear, and entities may also appear. It is recommended to carry a reliable light source and sleep holding any items you don't want to lose.
Entities inhabiting this level include faceless ones and hounds, and occasionally skinstealers. These entities rarely attack in groups and avoid light and large crowds.
Level Class: Unsafe

Level 0 is a nonlinear space reminiscent of the back rooms of a retail outlet. As in its first iteration, all rooms on Level 0 are uniform in appearance and share common features, such as yellow wallpaper, damp carpets, and haphazardly placed fluorescent lamps. Despite this, no two rooms are identical. The installed lamps flicker erratically and emit a constant hum. This sound is much louder and more intrusive than the hum of standard fluorescent lamps; an investigation of the light fixtures to determine the source of the noise has yielded no results. The liquid soaking the carpets has not been identified. It is not water and is unsafe to drink. The space on Level 0 can change dramatically: it is possible to walk in a straight line and end up back where you started, while retracing a previous route will lead to a new set of rooms, distinct from the one you've already passed. Because of this, and the visual similarities between rooms, navigation is extremely difficult. Devices such as compasses and GPS locators do not work within the level, and radio communications are distorted and unreliable. Level 0 is completely devoid of life. Despite being the main entrance to Backstage, no human contact has ever been reported within the level. Presumably, a large number of people died without ever finding their way out. The most likely causes of death are dehydration, starvation, and psychological trauma caused by sensory deprivation and isolation. Despite this, no bodies have been reported. Any group attempting to explore Level 0 will be separated until they escape. People on Level 0 are commonly subject to hallucinations.
