Liminal Spaces are created at the infinite-points where "[[Baseline Reality]]" converges with [[Unreal Space]], a 'state of existence' located on the periphery between things that exist and things that don't exist),in a way which leads to the laws of physics of the places they are derived from clashing or becoming non-functional. Living beings from standard realities may accidentally enter a Liminal Space thru various points where reality intersects with a Liminal Space (intersection points), allowing them to pass through what would otherwise be solid matter into said Space and back (as long as the bounds of the intersection point are used), though certain intentional methods of access have been discovered and exploited in the past. Within Liminal Spaces, most biological functions cease to some degree as while sensations such as pain and hunger can be felt they will never induce death, which is attributed to the flow of time within them being incredibly inconsistent and disjointed. Exit is possible by discovering a pre-existing intersection point with ones reality of origin, though this is often nearly impossible due to the Perception Principle.

As accidental access is possible, a population of [[Humans]] has over time accumulated within many Liminal Spaces with varying levels of organization which has allowed for the existence of certain small communities of people, though establishing a proper "society" within Liminal Spaces is nearly impossible. A rarely understood phenomena within Liminal Spaces is that their structure often only remains consistent via perception, if a route is not marked with something physical such as a string or tape, then the path travelled [https://simple.wikipedia.org/wiki/Schrödinger%27s_cat#Simple_explanation may not remain consistent] due to the lack of measurement or perception. [[List of Groups#Liminal Spaces-0|A group]] (if they run into each other in a stable point) can remain intact as everyone's perception and measurements keeps the area consistent and stable enough for said group to persist as long as they don't stray too far from their shared perception range (with said 'perception' including all physical senses, most notably sight and hearing), with multiple stable points allowing for communities to remain in contact either via couriers, travelling in a group, or wires which allow for limited communication. While many small communities and settlements do exist, contact is regardless limited and most that find themselves within a Liminal Space are left desolate and alone. Non-Human lifeforms seemingly native to Liminal Spaces are a rare occurrence, often being altered Humans or other unusual beings whose existence is rare and difficult to prove.

Certain rooms or locations naturally negate the perception principle known as 'stable points' which can be discovered as points of natural congregation (seeming appearing in many places at once, but being the same location regardless of position) where shared perception ranges can be created as long as a group remains intact, with those who stray too far easily being separated if the group perception range is exited by said individual. Liminal Spaces tend to be naturally isolating, with coming across others outside of stable points being nearly completely impossible due to their infinite scale, thus only a tiny fraction of individuals ever manage to join groups. The perception principle is also known to affect people psychologically, with those without something to 'ground them' often being subject to various psychological issues involving forgetfulness, dissociation, depersonalization, hallucinations, delusions, and paranoia especially if isolated from stable points or perception ranges, which are together classified under 'Liminal Maladjustment'.

Liminal Spaces are known to be derived from two sources which coexist to give them form, with the first of said requirements being a (usually) enclosed enclosed physical location (usually tied to specific intersection points) which is then expanded as the template for an infinitely expansive space via the Noosphere of those perceiving said Liminal Spaces as the sole source of information able to fill in the non-functional gaps left behind from the initial creation of the space. Access into Liminal Spaces is made possible via the previously explained 'Intersection Points' which make follow one of two types, with the most common types being one-way access points which allow access into a Liminal Space but only offer access across said Space if used within it, and the rare type being one seen in (Semi-)Transitional Spaces which act as a intermediary state between Baseline Reality and a standard Liminal Space which allows for access to-and-from both ends. All Liminal Spaces aside from (Semi-)Transitional Spaces are wholly detached from their reality of origin with no method of interconnection beyond access.

While accidental access thru Intersection Points is the most common route of access into Liminal Spaces, groups such as the SDS Foundation have managed to create artificial Intersection Points which allow for controlled access into specific locations (with the most notable being the Portal Matrix). As navigation through Liminal Spaces without measurement is incredibly uncertain, the SDS Foundation has made use of its own measurements to utilise them as a place to hide their facilities and activities at the cost of further destabilizing the Liminal Spaces they occupy via their artificial intersection points, making those aware of their presence opposed to their activities.

Transitional Spaces[4] are Liminal Spaces which are located in a intermediary position between Reality and a Liminal System (or are otherwise separate Spaces interconnected with Reality) which allow for navigation between Reality and a Liminal System, though they may rarely take the form of a location in reality with liminal properties rather than a fully-developed intermediary space which are known as Baseline-Type Semi-Transitional Spaces, which are contrasted by System-Type Semi-Transitional Spaces which are locations physically within reality but can only be accessed via Liminal Spaces and cannot be exited. Beyond Liminal Spaces which are clearly their own 'locations', many typically smaller Liminal Spaces known as 'Intra-Spaces'[5] may be connected to a 'parent space' which are either wholly distinct despite their connection or a partially separated offshoot of their parent with one entrance (which are both either naturally created or are created via the artificial construction of enclosed physical locations being subject to "liminal properties" for extended periods of time), though some (known as Inter-Spaces[6]) may be connected to two Liminal Spaces rather than one in order to act as a bridge between the two.
Liminal Space are each given a 'survival difficulty' warning which consolidates important information explaining how difficult to survive within a Liminal Space is into 3 categories; Safety, Consistency, and Maladjustment.
The safety of a Liminal Space may be classified as 'Safe' or 'Unsafe' depending on both environmental hazards and resource limitations alongside other factors which may affect survivability.
The consistency of a Liminal Space may be classified as 'Consistent', 'Sporadic Consistency', and 'Inconsistent' depending consistent navigation without a perception range is (without which areas are subject to change in form) within the Space, which can be improved by 'measuring' them with string or markings.
The maladjustment rate within a Liminal Space may be classified as 'No Maladjustment', 'Minimal Maladjustment', 'Low Maladjustment', 'Occasional Maladjustment', 'High Maladjustment', 'Critical Maladjustment', and 'Uncertain Maladjustment' depending on how prevalent "Liminal Maladjustment" is within the space, which refers to the culmination of numerous common psychological issues which Liminal Spaces may cause such as forgetfulness, dissociation, depersonalization, hallucinations, delusions, and paranoia.

Backrooms System (Limsystem-001)
The Backrooms is the largest known Liminal System to be discovered thus far and the easiest to access. Rather than as a Liminal Space, it is much better known as a series of interconnected areas (which gradually transition from one to another) where people can end up provided via an applicable Intersection Point, often taking the form of enclosed transitory rooms and environments familiar to Humans. In modern times methods of reliably creating permanent two-way entrances have been exploited, making accessing the Backrooms intentionally possible to those with sufficient technologies, though despite this a majority of the people within the Backrooms are still[7] people who ended up there by complete accident by accidentally falling out of reality into the Backrooms.
While in the modern academic circle the Backrooms consists of many "Sub-Spaces", many of the inhabitants of the Backrooms colloquially call the various areas that make up their dimension "levels", the archaic term for a Liminal Space part of the Backrooms System which was created before extensive understanding of the nature of Liminal Spaces and their multiple instances separate from the Backrooms due to its distinct nature as being the first to ever be discovered. The 'levels' are typically divided by a conventionally accepted entry point (such as a door, elevator, or hallway) or can only be accessed from domestic Intersection Points which collectively make up the Backrooms and house all things within the system. It is not entirely understood how the levels are 'positioned' in relation to one another, though studies into the subject are ongoing.
In reality, the Backrooms System heavily revolves around a space known as "The Lobby", a labyrinthine structure acting as the anchor from which all other iterations of itself (which are the other Sub-Spaces) extend from. As the Backrooms is incredibly closely tied to Baseline Reality, it can be inferred that most locations within the Backrooms are imitations of locations it is connected to within Reality alongside imitations of locations within the Backrooms itself, leading to a process of repeating abstractions which have together coalesced into what is known as The Lobby at the middle of everything. While The Lobby is particularly susceptible to the structural alterations when not measured or perceived consistently, its monotony has been deemed safe enough for many of the largest enclaves of surviving Humans to establish encampments in.
The Lobby
As previously described, The Lobby is the "first" Sub-Space within the Backrooms which acts as the primary overarching structure of the whole system as nearly everyone who accidentally enters the Backrooms ends up there and virtually every other Sub-Space acts as an abstracted version of The Lobby attempting to imitate the points in reality its connected to. The lobby takes the form of a infinite office building with a seemingly infinite number of segmented rooms and corridors nearly universally covered in dull-yellow wallpaper and moist tight-nit carpets whose monotony is often sufficient to cause significant psychological distress in the form of isolation, paranoia, and depression. The Lobby is particularly notable for how susceptible it is to the structural changes often caused by the Perception Principle, as areas which are not actively observed or physically marked often tend to rearrange themselves given enough time unaccounted for (aside from 'stable points' where such restructurings are negated), making traversal often difficult as backtracking is not possible most of the time. The entire Backrooms System heavily revolves around the Lobby as the anchor from which all other iterations of itself (which are the other Sub-Spaces) extend from.
While it may seem to be rather random, the Lobby is home to a number of architectural variations which present as visually different rooms or 'segments'. Many simple segments are simply areas where the texture of the wallpaper changes up/down a staircase, where rooms of similar design repeat in a massive grid-like pattern, and areas where the layout of the Lobby changes drastically. More complex aberrations include rooms of wholly differing design such as archways elevated above the carpet, rooms full of lattice/grid-patterned pillars, groups of pits leading deep into the ground without an end in sight, areas where the otherwise loud buzzing of the lights cuts out as everything is an eerily silent darkness, rooms with deep-red wallpapers which completely enclose one within them without a method of escape, among many others.
Other Sub-Spaces
Beyond the expansive Lobby, the following is a list of other Sub-Spaces that find themselves within the Backrooms System:
The Outer Rooms were a collection of several liminal spaces which existed until the MV209 event, which either destroyed them or eliminated all connections method to them.
The Living Rooms is the first safe and stable Liminal System to be discovered, with the entrance found in a mansion located east of Alephitis, Tritonien.
In the year 209 a catastrophic event happened in the New Frontier, Damp Hallway and Doorway limspaces, which were all once part of the Backrooms. The Event, which was named "MV209" ("Multiverse '209") was caused by Fracture being completely healed, which simultaneously caused entrances to the three Liminal Spaces to stop working as intended. It is thought that they were completely, because all communications from SDSB operatives in the 3 levels cut approximately 18 minutes after the initial MV209 event. Following MV209, anyone who attempted to use the former entrances to these three levels would "Go somewhere deeper". Until the year 281, nothing was known about this "deeper" area. Until a full drone-investigation began into the area. It seems to be a system of enigmatic liminal spaces found deep down below underneath the entirety of the backrooms.
The 'Deeprooms' are completely barren despite a constant feeling of being watched.
Solitary Liminal Spaces are independent Liminal Spaces which are not connected to any larger System, making them often much more isolating due to the lack of transition to other "landscapes". The following is a list of such spaces:
There are a plethora of strange, unexplainable occurrences which occur within Liminal Spaces - unexplained, unnatural occurences that are typically not fully understood. These are known for defying the laws of physics, pushing the bounds of ideas such as time and euclidean geometry, bending reality as we know it. As these phenomena can include a wide array of inexplicable events, it is advised to use caution when exploring sub-spaces that are unexplored or poorly understood.
Fracture
Fracture was a mysterious affliction present within the Backrooms since the creation of the exit portals - whom had supposedly been causing levels to act unusually and hinder domestic Intersection Points. More common theories on why this was occurring was due to the portals 'tugging' on the Backrooms as a whole, although this was never proven. Fracture was eventually repaired after a large deposit of Fracture Weld was discovered.
Nihilantis Effect
An example of the Nihilantis effect taking place in the Decrepit Hospital. The red-shifting may or may not be a result of the reflection of light around the object due to repulsitivity, however this may also be partly attributed to the effect itself.
The Nihilantis Effect is a strange phenomenon caused by excessive duplication. It is estimated that it happens once in every 2500 duplications, but research shows it can be made artificially, given enough energy.
Utilising replication technology can be an arduous task in Liminal Spaces due to the Nihilantis effect, which is a strange phenomenon that causes some duplicated items to appear as if the viewer had double vision. This duplicate object can be interacted with, however it adheres to different laws of physics. Instead of having attractive gravity (although extremely small given the density, this can vary,) it obeys the laws of antigravity, and instead it repulses matter. Again, this effect is not visible to the naked eye or even microscopes, but an object with large enough density could almost certainly have visible properties. The atoms of the object, when inspected, are consisted out of antiprotons and antineutrons, which are made out of antiquarks, (and even very rarely, strange and charm quarks in their normal variant)with a nucleus orbited by positrons. As it is further investigated, the anti-object shows mostly opposite traits to normal objects. However, the SDSB is researching the qualities of the anti-objects caused by the Nihilantis effect, and are yet to discover whether the anti-object has negative mass. Currently, their weighing scales only show it as either positive or even 0, propagating this theory. If proven to be true, it becomes a good candidate for the hypothesised 'exotic matter,' which demonstrates strikingly similar properties.
The Barrier
"The Barrier" is a largely unknown phenomenon that takes the form of an impassible "wall" that can be encountered in some regions of the Backrooms, making crossing it incredibly difficult. There are several unusual and chaotic sub-spaces within The Barrier such as the Borderzone, In Between, and the Voidzone. Through these sub-spaces entrances to The Outer Rooms were at one point found, though these no longer work.
Unraveling Cascade
The "Unraveling Cascade" is a hypothetical scenario in which a specific and hazardous enough Castrovalence Anomaly manages to initiate a run-away chain of Liminal Space formations akin to false vacuum decay, slowly spreading out as the entirety of the universe is consumed by Liminal Spaces one by one as it is reshaped into an interconnected mess of countless infinitely-sized spaces representing each individual room which had existed in the past. The feasibility of this scenario happening is uncertain, but largely thought to be incredibly unlikely.
Entity Sightings
There have been many reports of unusual lifeforms seemingly native to Liminal Spaces with their own motivations, abilities, behaviours, habitats, and physiological needs including wholly alien lifeforms created to inhabit the environments they exist in and lifeforms who act as reconstructions of Humans which aim to mimic their appearance, though due to the frequency of Liminal Maladjustment and the lack of extensive evidence few "entities" have been verified to exist.
Many similar objects with a myriad of functions have been found within Liminal Spaces, ranging from tools, weapons, consumables, or other items. Many of these follow the rules of their reality, being found as mere decorations for individual Liminal Spaces, while others are real-world objects altered by a Limspace upon entry, and some are even created by the people who reside within Liminal Spaces. Some may be dangerous, while others may be crucial for survival - thus identification of objects is extremely important if one wishes to make use of them.
