Liminal Spaces

A Liminal Spaces (sometimes shortened to limspaces) are physical Dimensions that can be interacted with as if they were ordinary locations despite possessing various inconsistencies in how reality 'functions' within them, causing them to be exceptionally unstable places where the laws of physics and nature and even ones own perception cannot be safely relied upon, with many of them being believed to have been sourced from limited information or even vague memories of those which have entered them. Most Liminal Spaces are infinite, non-euclidean environments which often invoke feelings of uncanny familiarity, eeriness, nostalgia, and apprehension upon those who end up within them. A common theme of Liminal Spaces is an 'abandoned' or empty caricature of a familiar place or environment derived from the space's "source", often being transitional in some form, such as hallways, waiting rooms, parking lots and rest stops. While this definition is the most common type of environment present in Liminal Spaces, it should be noted that Many Liminal Spaces also take the form of places that are simply nostalgic, dreamlike, and/or uncanny, with the absence of people becoming their only unifying trait (Except in constructed settlements).

A surprisingly large number of Human settlements have been created within Liminal Spaces by those that have accidentally ended up here alongside various groups which have intentionally sought them out in order to operate in secrecy via the isolating effects of Liminal Spaces. Liminal Spaces act as points where multiple realities converge, often being intertwined with a location in 'Baseline Reality' where they may be accidentally accessed and the outermost reaches of a reality known as the Spectrosphere, an aggregation of numerous interconnected astral planes which share similar properties to Liminal Spaces aside from being enclosed from other beings, with Liminal Spaces being just barely tethered enough and peripheral enough to allow other beings to accidentally end up within them via a process known as 'Noclipping' which caused them to fall out of their native reality into a Liminal Space, though some non-accidental methods of entering do exist. The level of safety or danger within Liminal Spaces are designated via 'survival difficulty' categorizations, with the 'safe/unsafe' element specifying whether or not the limspace is safe to travel through or reside in, the 'secure/unsecure' element specifying how well they are mapped and how easy they are to navigate, and the 'devoid/minimal/low/medium/high/infested/undocumented entity count' specifying how prevalent non-Human lifeforms are within said space, though some survival difficulties may vary from this template.

Types of Liminal Spaces

• Liminal Systems: Liminal Spaces often can connect and amalgamate together into what is known as a Liminal System or Cluster. These Systems can be composed of hundreds or even thousands of Liminal Spaces.
• Sub-Spaces: A "full" Liminal Space that is part of a Liminal System. A common colloquial term for such a dimension is the term 'Level'.
  • Enigmatic Sub-Spaces: More difficult to access, and much more mysterious Sub-Spaces. Many of these lack an ordinal placement within their systems, instead having unknown positions.
• Transitional Spaces: A Liminal Space which is located in a intermediary position between Reality and a Liminal System, or a Limspace otherwise also connected to Reality. These often allow transport between Reality and a Liminal System, although this is not necessarily the case. These may also take the form of a location in reality with liminal properties, often acting as a gateway for transport between reality and liminal systems.
• Semi-Transitional Spaces: A unique variant of Transitional Space that has 2 different types, these being the "System-Type" and "Baseline-Type".
  • System-Type: System-Type Semi-Transitional spaces physically exist in reality, but can only be accessed via full transitional or liminal spaces.
  • Baseline-Type: Baseline-Type Semi-Transitional spaces are locations in reality with liminal properties, acting much like a pocket dimension. They don't necessarily lead to a liminal space/system. (but they can in some cases.)
• Intra-Spaces: Distinct Limspaces that are related or connected to a larger parent level. They may either directly part of their parent level or still connected while existing in a separate space. These are usually naturally created, but some circumstances or methods have allowed the creation of new Intra-Spaces.
• Inter-Spaces: Limspaces located between two separate Limspaces. In some cases they may act as a 'bridge' between the two Sub-Spaces.
• Micro-Spaces: Typically distinct locations that are too small to be considered their own level.

How are Liminal spaces Created?

Liminal Spaces are unusual realities generally derived from enclosed physical locations in a 'standard' reality that have been subject to a Castrovalence anomaly, effectively ripping said location from reality in a process which distorts them into a 'Liminal' state as their only tether to a larger reality is either the Spectrosphere or each other, deriving additional changes from the collective nostalgia of those inhabiting the space in order to craft the familiar yet alien landscapes one finds within Liminal Spaces. People which enter the location where a Liminal Space is derived from are able to accidentally end up 'no-clipping' out of reality and into the Liminal Space, though intentional access is also possible via gateways or finding entrances to (Semi-)Transitional Spaces. Despite being tied to physical locations in reality, after having undergone their Castrovalence Anomalies all non-Transitional Liminal Spaces become completely removed from reality as essentially their own dimensions, allowing many proximate Liminal Spaces to end up 'tangled together' in order to form Liminal Systems consisting of countless interconnected limspaces.

Backrooms System

Designation: Limsystem-001

The Backrooms is the largest known Liminal System to be discovered thus far. Rather than as a Liminal Space, it is much better known as a series of enigmatic sub-dimensions where people from anywhere in the multiverse can end up, provided they noclip out of "reality". The Backrooms can be accessed via any location in the multiverse, although the location within the Backrooms which each location in reality leads to can differ, fitting the memories of the natives of whatever area enters. For Humans, it takes the form of nostalgic urban rooms and environments for the most part. Some of the more unusual areas may be ones generated out of the nostalgia of distant alien races.

In modern times methods of reliably creating permanent two-way entrances have been discovered and developed, making accessing the Backrooms fairly easy. Thus, some more adventurous individuals have intentionally used such gateways to enter the Backrooms to explore it temporarily or to permanently move into it. Despite this, a majority of the people within the Backrooms are still people who ended up there by complete accident by accidentally falling out of reality into the Backrooms.

Sub-Spaces

While in the modern academic circle these are known as "Sub-Spaces", many of the inhabitants of the Backrooms colloquially call the various realms that make up their dimension "levels". Level is the archaic term for a Limspace part of the Backrooms System. This name was created before extensive scientific 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 door, floor, or can only be accessed from no-clipping. They 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.

The Deeprooms

Designation: Limsystem-004

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 limspaces 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 of native life/entities. Despite the lack of entities there is still a constant feeling of being watched.

Solitary Liminal Spaces

Solitary Liminal Spaces are are independent and not considered part of a Liminal System. They are often isolated and solitary by nature.

Phenomena

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 no-clipping. 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.

Entities

Entities are unusual lifeforms which often permeate within Liminal Spaces with their own motivations, abilities, behaviours, habitats, and physiological needs which make them often quite unpredictable, with many of them either originating from the 'higher' Spectrosphere or evolving to mimic Humanoid entities via mimicry, thus 'unusual' persons within Spaces known to house such entities are to be avoided for one's own safety.

Objects

Objects are tools, weapons, consumables, or other items used or found by the inhabitants of Liminal Spaces. Many of these follow the rules of their reality, being found as mere decorations for individual Limspaces, while others are real-world objects altered by a Limspace upon entyy, and some are even created by the myirad of people who reside within Limspaces. 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.

Groups

Countless organizations or groups have forged their existence in a myriad of liminal spaces. Groups have their particular objectives and justifications for which they are developed. Factions, groups, and organizations can be varied, including varieties such as; task groups, command groups, religious groups, and many others.
