==What are Extradimensional Spaces?==
=== TLDR: ===
An Extradimensional Space is anything outside of Yata's Home Dimension.
=== Full Explanation: ===
An extradimensional space is any location situated somewhere else in the omniverse than the dimension in which Yata takes place, in this case the dimension of focus in Yata is Dimension-002. Extradimensional spaces can take many forms, the important two primary types are Divergent Dimensions and Locational Dimensions. Sometimes dimensions may not fit into either category, and are thus known as "NA Dimensions"Meaning "Non Applicable Dimensions.
=== Divergent Dimensions ===
Divergent DimensionsAlso known as Universes, Timelines, Parallel Dimensions, Alternate Universes, etc. can be imagined as "timelines", forming every planck time based on binary choices taken in other universes no matter how significant or insignificant they are. This process is known as divergence, taking both a Standard and Advanced form. Standard Deviation is the previously explained method of universe formation, occurring every planck time. Advanced Deviation however is often both more unstable and unique, as it forms entirely new dimensions, with new properties and eventsA "Universe-One", which later will undergo Standard Deviation. The ratio of Advanced Divergence to Standard Divergence is measured with Castrovalence with 1 Castrovel being the "maximum" possible integer of Advanced Divergence, only usually being caused by a Dimensional Merger or Collision. There are some reports of Castrovalence Anomalies occurring in such events, in which its integer rises above 1, leading to the formation of an Atypical Locational Dimension or Dimensional Corruption.

=== Locational Dimensions ===
Locational DimensionsAlso known as Realms or Enigmatic Dimensions do not undergo divergence, and are formed by Castrovalence Anomalies. They take the form of a place instead of an universe, an example of this is Liminal Spaces, which take the form of infinite structures or environments. There are various different types of Locational Dimensions, as the term is generally very broad encompassing; Liminal Spaces, Liminal Systems, Transitional Spaces, Pocket Dimensions, Metaphysical Spaces, Synthetic/Digital Realities and some Alternate Realities. The main unifying factor of they are each physical spaces, instead of locations within a cosmos.

=== Dimensional Forms ===
Additionally there are 4 other documented "Dimensional Forms" which may be attributed to Divergent or Locational Dimensions, but are not necessary for these to exist. 
# Mathematical Form: An extension or reduction to the traditional "3 dimensional space", such as the 2nd or 4th dimension. They may still react with our reality, much like how a sphere would pass through a flat 2 dimensional plane. These kinds of dimensions do not exist as entirely separate realities from 'standard 3rd dimensional reality', instead taking up the same space in a "layer"This "layer" is often imperceptible or unreachable to lower dimensional lifeforms. above it in the same general space.
# Temporal Form: A form of dimension dealing with Time in some form, such as the passage of it. While often having altered passage of time, such dimensions may also allow things such as Time-Travel to take place.
# Space-Time Form: Dimensions which simply coexist with our dimension within the Omniverse, they may take the form of an altered version of our home dimension either historically or physically, or something else physical and separate within the Omniverse.
# Astral Form: Dimensions which coexist with the material dimension that we exist within. Often takes the form of a psychic or spiritual connection or realm, such as the Noosphezre or one of the various Afterlives. Access to astral may be possible via methods such as religion, dreams, death and rituals, allowing for abilities such as psionics and mind-reading.
Many (But not all) "Astral form" dimensions are not applicable to the standard "Divergent" and "Locational" categories, and instead are classified as "NA" which stands for "Non Applicable"

=== Dimensional Sub-Types ===
Dimensional "sub-types" are ways to describe the structure or nature of a dimension in a more specific topograhical sense.
# Alternate Reality are entire universes taking the form of a Locational Dimension.
# Sub-Dimensions are dimensions connected together, most known Subdimensions are Locational Space-Time dimensions that have connected and amalgamated together into what is known as Systems, the most notable type of these is Liminal SystemsAlthough they also may be connected to Divergent Dimensions..
# Pocket-Dimensions are smaller dimensions, which are either too small or too connected to a larger reality to truly be considered their own "dimension", instead acting like a 'bubble' connected to a larger reality.
# Liminal Spaces take many forms and sub types, albeit all sharing common characteristics. They are typically an Architechtural or Environment based Locational Dimension, feeding off of nostalgia from the Collective Consciousness of its inhabitants to make an eerily familiar and nostalgic appearanceSee the "Liminal Spaces" article for more details..
#Synthetic/Digital Realities are computer-constructed realities, which often operate similarily to a Pocket Dimension.
#Interdimensional Constructs are metaphysical formations existing within and outside of multiple realities. They often act as nexuses allowing for travel into other realms.
#Metaphysical Spaces are more "abstract" realities, which typically cannot be interpreted or understood without risk of mental damage.
#Crossroads are dimensions accessible from a locationThese are typically anomalous
 within a standard reality which leads to a dimensionthe Crossroad housing several easily-accessible Gateways to other realities.
#Afterlives are realms where the soul or identity of a deceased being may end up. These may vary from paradise, to limbo, to perdition, to something completely different.
====Liminal Sub-Sub-Types====
There are several different types of types a Liminal Space can be such as;
#Liminal Systems are amalgamated/merged collections of other Liminal Spaces.
#Sub-Spaces are a Liminal System's Sub-Dimensions.
#*Enigmatic Sub-Spaces are more mysterious and difficult to access Sub-Spaces which typically lack a clearly defined ordinal placement.
#Transitional Spaces are situated in an intermediary position between reality and a liminal space/system. They are typically "bridges" between reality and a Liminal Space/System
#Semi-Transitional Spaces are a variant of Transitional Spaces with 2 different types.
#*System-Type Semi-Transitional Spaces physically exist within reality, but only can be accessed via a Liminal space/system
#*Baseline-Type Semi-Transitional Spaces are locations in reality which possess Liminal Properties, acting much like a Pocket Dimension. They do not necessarily lead to a Liminal Space/System.
#Intra-Spaces are distinct Liminal Spaces connected or related to a "parent liminal space".
#Inter-Spaces are typically smaller Liminal Spaces situated between two Liminal Spaces, acting as a form of bridge.
#Micro-Spaces are locations that are too small to be considered their own level, while still being distinct.

==Structure of the Omniverse==
While much of known reality is vague with a lack of purpose, a pattern on how it functions can be still be documented. But first off:
=== What is the Omniverse?===
The OmniverseAlso known as a "Cradle" is the current overarching structure of our current reality, containing all known dimensions, realities and multiverses within it. Whatever lays beyond the bottomless void surrounding it is completely unknowable, and unreachable. At current times, there is no proven unifying explanation of how the Omniverse works, or was formed, although several philosophies, religions, and smaller institutes have proposed various explanations such as: 
* The Hyacinthan Religion describes the "current" omniverse as the Second Cradle, an all encompassing everything succeeding a preceding First Cradle, which was consumed into the Primordial Void, a infinite chaotic nothingness surrounding all of existence home to unknowable horrors.
* (add more)
=== Unreality ===
"Unreality" is the term for the area on the periphery of the Omniverse where matter is no longer capable of permanently existing. Dimensions are generally not located within Unreality, though some abnormal realms are situated near the 'edge' of where matter survives, and where it fades away into the void such as The Wastes, Kurgan and Incarce.
===Multiverses===
The Omniverse is composed of several distinct layers of reality, known as "Multiverses" or "Realms", which all have distinct characteristics and rules. Each Multiverse is composed of several dimensionsCan be divergent, locational or anything else. which each inherit the traits and rules of their parent multiverse, while often having some of their own properties.
Each Multiverse is its own distinct layer of reality, being ordered from 'highest' to 'lowest' is based on each individual universe's "Average Reality Stability" (ARS) rating. ARS measures the stability of realitySee "Physics" Section by measuring how much 'reality'As a semi-tangible concept or substance. exists within any given area or dimension, with dimensions that have a Low ARS score having a very unstable and fluctuating nature, dimensions with a Medium ARS score being generally similar to Baseline Reality, and dimensions with a High ARS score often appearing overwhelming or otherwise 'magical' in the eyes of standard beings that enter them. 
===== Some Multiverse Trivia: =====
* Each Multiverse has its own localised Noosphere, which may cause some issues with travel to other dimensions due to Noospheric Syndrome.
* Multiverses aren't necessary fully self contained away from each other, and can physically overlap or otherwise exist in the same general area.

==Extradimensional Travel==
Traveling to other dimensions may be difficult, but is still very possible as long as you know what you're doing. While dimensions may exist in the same "plane of reality", simply traveling beyond a universe and finding the next one over is not possible, you must instead use a more esoteric method of travel such as:
===Gateways===
Gateways are naturally occurring spatial distortionsIe; "Portals" that connect dimensions and sub/pocket dimensions together, allowing long-distance interdimensional travel via the transfer of matter. These gateways can be traversed through with relative ease, as little to no physical ailments or aftereffectsThough, some Gateways leave trace amounts of Tachyon Particles on matter that has passed through them. This is generally harmless. are known to occur after the fairly seamless transition between the two points connected by the Gateway. 
While some Gateways are naturally open, many need to be activated via a magical incantation or key phrase. Creating a new Gateway is much more complicated, requiring a thaumaturgic ritual. Gateways only connect dimensions together, never two points within the same dimension.
Whilst travel between dimensions of a single multiverse is completely safe, some complications may occur with extra-multiversal travel due to various factors, such as Noospheric Disorder.
===Portals===
Via utilising advanced technologyTypically Paratechnology or Technomagic or specialized rituals, it is possible to construct an artificial portal that acts as a gateway. Most organizations have not learned how to create such gateways, with notable exceptions such as the SDS Foundation. Archaic models of such a gateway resemble large circular doors, but modern ones function much like standard teleporters.
===Psuedospace===
Psuedospace is a method of FTL Travel much like Hyperspace, although instead it uses the extradimensional void as its method of travel. How it works is that a machine known as a "Psuedospace-Drive" can be built into a space vessel, allowing for what is known as "Psuedospace Jumps". If a Psuedospace Jump is done correctly, it allows jumps to other dimensions by accelerating to >68 km/s/Mpc.

===Noclipping ===
Noclipping is a phenomenon that may rarely occur in any standard reality forcefully sending someone or something into a Liminal Space/System. This phenomenon is also active within a Liminal Space, being a common method of travel between Sub-Spaces of a Liminal System.

=== Reality Stability ===
"Reality Stability" is a unit of value which describes the integrity of reality itself in any given area with "Local Reality Stability" (LRS), and is also used to evaluate the stability of an entire dimension via "Average Reality Stability" (ARS) and the stability of a anomalous person via "Personal Reality Stability" (PRS). All 3 of these measurements are measured on a scale from 0-100+, with 0 representing a reality with no stability whatsoever, and 100 representing the baseline ARS level found within Yata's Dimension, numbers above 100 would represent a reality with a ARS rating higher than Yata's Baseline. Reality Stability is hard to explain, but is best explained as the 'amount' of reality in a given area or dimension, meaning that reality is weaker in a Low-ARS/LRS area, and reality is much stronger in a High-ARS/LRS area.
An area, person, or object with a higher LRS/PRS reading can often bend reality in an area with a lower LRS/ARS reading if the difference is significant. Even a normal person can theoretically have anomalous capabilities in a Low-LRS/ARS area, while already anomalous individuals & objects abilities are enhanced. For normal individuals these capabilities fade once they exit an area with much lower LRS/ARS. Weaker LRS/ARS also allows the existence of unusual things such as anomaliesIncluding Objects & Entities, whose effects still linger after exiting their origin area for unknown reasons.
An area, person, or object with a lower LRS/PRS reading lacks anomalous capabilities in higher LRS/ARS area, with already anomalous individuals & objects often having weakened or completely null anomalous capabilities. Such areas can often be overwhelming to lower LRS/PRS individuals and objects, as they can easily be overpowered by the anomalous energy within these areas.
Castrovalence affects Reality Stability in some form, with higher castrovalence dimensions typically having a Low ARS score.
===Interconnectivity Variable===
The Interconnectivity Variable (IV) is a rating of 1-10 that describes how easy it is to travel from 1 dimension to another dimension. The Variable applies specifically to the travel between 2 specific dimensions, instead of travel from/to 1 specific dimension. 10 represents travel being easy, while 1 represents travel being very difficult.
===Temporal Anomaly Theory===
Temporal Anomaly Theory is a possible explanation for false memories, the mandela effect, and historical inconstancies. The theory is that such 'anomalies' are caused by brief moments of dimensions intersecting each other, causing a brief anomaly within the Noosphere leading to such inconsistencies.
=== Temporal Disparity ===
Temporal Disparity is a phenomenon which may occur in various dimensions which causes the flow of time to be altered within them, either being faster of slower than standard time. Temporal Disparity is often associated with Temporal-Form Dimensions, but may occur elsewhere as well.
=== Temporal Misalignment ===
Temporal Misalignment is a phenomenon in which some timelines may hold the same events, but occur at completely different times on a multiversal scale, with some divergences of a "present" event taking place thousands of years in the past for example. This allows for further advanced or futuristic dimensions, or undeveloped and primitive iterations of Yata to co-exist with its "true" incarnation.
==Interdimensional Index ==
The Interdimensional Index is a standardized numerical system for identifying a specific dimension without using a name. 
=== How does the Interdimensional Index work? ===
In order to figure out the Interdimensional index for an individual dimension, follow this tutorial: Each index starts with "Dimension-" followed by "Div:" if it is divergent, and "Loc:" if it is locational.
=====Divergent Dimensions=====
If it is a Divergent dimension, follow "Div:" with the year the divergence took place, followed by a period and a 1 word describing what caused it, followed by a period and a number signifying which specific divergence caused by this thing on this year is. If this is the first or "prime" iteration of this divergence, have the number be 0. Then you can finally add a slash and the number of the specific dimensional formSee the "Dimensional Forms" section it takes afterwardsIf Applicable. 
Example: "Dimension-Div:158.Yetia.3/3" This example is a the Third Divergent Spacetime Dimension caused by something in Yetia in the year 158.
If the specific divergence is unknown, then the middle sectionAfter Div: but before /num is replaced with "MD", meaning missing data, followed by a slash, the year of discovery and then a period followed by a number signifying which specific divergent dimension with missing data is discovered in that year. If it is the first or only iteration of a MD divergent dimension on that year, have the number be 0.
Example: "Dimension-Div:MD/340.0/3" This example is the First Divergent Dimension to be discovered in 340 which does not have enough known about it to determine its divergence.
=====Locational Dimensions=====
If it is a Locational dimension, follow Loc: with the number of the Dimensional Sub-TypeSee the "Dimensional Sub-Types" section In most cases (With 2 exceptions, which will be explained last.) this would be followed by a slash, the number of the specific dimensional form followed by a slash, the year of discovery/documentation and if there are multiple such dimensional subtypes discovered on that yearIf these are interdimensional why does it include the year of Yata's dimension? well the reason is it's simple and doesnt require me writing an entire standardized interdimensional timekeeping system. followed by a period and which iteration of such a locdimensional subtype found on that year it is. If it is the first or only iteration of this locdimensional subtype on that year, have the number be 0. 
Example: "Dimension-Loc:1/3/298.0" This example is the Only Locational Spacetime Dimension discovered in the year 298 classed as a "Alternate Reality". 
As mentioned earlier in brackets, there are 2 exceptions. The First exception applies to the Dimensional Sub-Type section of a locdimension's index. If it is either a Subdimension, Pocket Dimension, or Synthetic/Digital reality add the middle partThe Divergence or Sub-Type identifier alongside the Div or Loc Prefix of the dimension it is located within or connected to, albeit with the Div: or Loc: segment changed to just be the first letter and all periods removed. 
Example: "Dimension-Loc:3.D341SDS4/3/363.2" This example is the Second Locational Space-Time Pocket-Dimension located within the fourth divergent timeline caused by the SDS in the year 341 to be discovered in the year 363. 
The second exception is if it a non-standard e Liminal Space, in which you would follow the Loc:4 with a period and the number of the specific Liminal Sub-Sub-Type. If the Sub-Sub-Type is a Semi-Transitional Space, follow the STS's number4 with either a S or B depending on if it is a System-Type or a Baseline-Type, then add a period and the System's Liminal System DesignationSee the first line under any Liminal System on the Liminal Spaces article. if it is a System-Type, and the First Exception's system for identifying which dimension it is located in if it is a Baseline-Type . If it is a part of a Liminal System.1 would reefer specifically to the system. follow the sub-sub type with a period and its Liminal System DesignationSee the first line under any Liminal System on the Liminal Spaces article.. 
Example1: "Dimension-Loc:4.1/3/150.0" This example is the first/only Liminal System to be discovered in the year 150. 
Example2: "Dimension-Loc:4.4B.D231Luxuria0/3/290.0" This example is the First/Only Baseline-Type Semi-Transitional Space to be discovered in the First Divergent Dimension to be caused by something related to Luxuria in the year 231 to be discovered in the year 290. 
Example3: "Dimension-Loc:4.2.001/3/193.2" This example is the Second Sub-Space within the Backrooms (Limsystem-001) to be discovered in the year 193. 
=====Non-Applicable Dimensions=====
Some dimensions such as many Astral Form dimensions do not specifically apply to Divergent or Locational dimensions, replacing the middle segmentThe Divergence or Sub-Type identifier alongside the Div or Loc Prefix of an index with "NA-" followed by the dimensional formSee the "Dimensional Forms" section, then a slash, then the year of discovery and a number signifying which specific divergence caused by this thing on this year is. If this is the first only iteration of this NA Form to be discovered on the year, have the number be 0. 
Example: "Dimension-NA:4/392.3" This example is the third Non-Applicable Astral Dimension to be discovered in the year 392
==Other ways to name dimensions==
While the Interdimensional Index is the multiversal standard method, several other methods have been locally used by individual organizations.
=== Name System ===
Some dimensions have a largely accepted name which goes above simply being one of many nicknames, and these dimensions are thus usually referred to by their name.
===Timeline-### System===
Several organizations in Dimension:Div:79.RedLeader.0/3Ie Yata's dimension.such as the Yatan-Theian Accord's Extradimensional Matters Division use a system of simply naming divergent dimensions based on the order they have discovered them, simply ordering them based on discovery. For example, the term they use for their home dimension is Timeline-002, since it is the second one they discovered.
