Nasuverse

==Summary==
Nasuverse is a collection of multiple franchises by the author Kinoko Nasu. Which are all canonical to cosmology in which some of them take place in parallel worlds or different timeliness being canonical to each other.
The verse has a very complex cosmological structure with celestial bodies having wills of their own and having authority that surpasses most low end, mid end and high end characters of the verse some of the celestial bodies; being or having higher dimensional status and being capable of reaching multiverse cosmological status (e.g mooncell and planet earth) and with multitude of concepts that distinguishes it from other fictional verses like "the counter force" "mystery" making it function under completely different rules compared to fictional verses.
==Power of verse==
It's also a fictitious verse containing impressive and broken powers and hax in terms of quality and quantity predicated from its complex power systems most of them being layered as; most of nasuverse powers, resistances and hax end up being layered
Nasuverse low tiers are less impressive physically but in terms of conceptual power they're quite powerful with magus mere humans capable of producing low end magecraft possess higher dimensional hax and conceptual power even while they possess 3 dimensional bodies with servants being similar not necessarily being higher dimensional but still possessing capabilities of interact with them through noble phantasms the mid-tier end of the nasuverse which comprises of servants for the most part is around Low 2-C with a small amount of servants theoretically reaching 1-T through high end, noble phantasm with nasuverse high tiers such as enuma elish is capable of destroying earth which functions under many worlds interpretation with the divine spirits and God's existing in higher dimensions beyond the laws of the humans which includes the entire system of quantum mechanics.
Mid-tier gods being around 1-B and higher dimensional and high tier gods and divine spirits such as Zeus being higher 1-T+ God tiers such as Arcueid are capable of reaching levels of 1-T+ who wields authority superior to heroic spirits; the latter being 1-T+, heroic spirits in their true forms such as Gilgamesh's existing in the throne of heroes which exist transcends space time and lacks such concepts making them 1-T+, the pinnacle nasuverse power ends Tier 0 with the indivisible Swirl of the Root a place beyond space, time , dual systems and conceptualization a place inspired by Taoist views of "God".
==Cosmological Structure==
Nasuverse contains infinite parallel worlds confirmed to derive direct from quantum mechanics, which entails it functioning under MWI as such it should contain infinite dimensions that derive from the abstract Hilbert Space.
Celestial bodies are the ones that contains their own cosmos for example earth itself containing notions mentioned above, amongst these layers there's the reverse side of the world which transcends all things mentioned above existing in even higher dimensions.
The entire universe in itself is quite big; as it encompasses all of that and even other celestial bodies with their own cosmos like the moon cell which exists in the moon containing 8 dimensional walls that defend the core; which is higher dimensional existence in itself and the time cage which contains extra temporal dimensions and is said to be beyond everything in the moon cell excluding or including the core.
To the outside of the world there's the  Outer God's realm and the throne of heroes both of which exist 1 layer beyond the universe which is already 1-T+ making each realm atleast Higher into 1-T+.
==Celestial Bodies==
Every planet has follows its own concepts and common sense and consistently contains its own cosmos. Which is why when ultimate ones come to earth it's hard to combat them as they embody concepts different from that of Gaia conceptsAngel Notes.
==Earth and Textures==
Earth has separate realities some of them being parallel worlds and others being higher dimensions, these are referred to as a textures of reality, Textures play a fundamental role within the nasuverse in separate myths from other myths the existence of textures allows for all myths within the nasuverse to exist without being contradictory to each other as seen. Every myth took place within its own texture of reality such as the Scandinavian myths and events like Ragnarök. The planet alters its physical laws according to the beings that live on its surface, this was responsible for the separation of the textures of deities and humans. As they had functioned under laws that were incompatible with each other.
==Humanities Texture==
Parallel Worlds are notions of human history and exist within the first texture of the world the texture of humanity, which was insinuated to be a universe as seen when Arcueid used event storage to store the surface texture of the planet and tohno going inside that and ends up witnessing a infinite universe along with its concepts and endless stars, This first texture containing a universe branches out into endless possibilities which exist as parallel worlds, these possibilities branch off one anotherLord El-Melloi II's Case Files - Light Novel Volume 4, these countless possibilities form the concept of human history, all of these possibilities are said to be from quantum theory. 
This corresponds to the nasuverse and how the parallel worlds which are physical quantities which are wave with the mention of them not leaping to each other's wavelength like these possibilities can be calculated in the same way how probability distribution works in quantum mechanics except time probability distribution pertains to real physical quantities or these parallel worlds. 
Zepia states that he can calculate the wave length with the highest possibility of occurring or determine a possible outcome from calculating the wave lengths probability distribution. It is however impossible to calculate the probability distribution of the entire system as new possibilities continuously branch over and over again.
As a result of these parallel worlds existing in a wave-like state and the concept of "possibilities" in itself is intrinsically tied to quantum theory. Then the possibilities arise from superposition, however since the possibilities are a physical constant. The abstract vector space which ought to describe the physical constant, instead becomes something equivalent to to a physical vector spaces. Hence suppose the countless possibilities are there, it implies that each possibility being a quantum state implies the existence of countless state spaces underlying the physical constants as quantum systems (the possibilities in this case). 
In this context, the Hilbert space, which is a mathematical framework used to describe the state of quantum systems, would be considered equivalent to a physical vector space or spatial dimension. Instead of governing abstract phenomena like quantum states, the Hilbert space itself would represent the underlying structure of physical reality, where quantum states are the physical constants. This interpretation suggests that the fundamental fabric of reality is structured by these quantum states within the Hilbert space, much like spatial dimensions govern the physical layout of our universe.
==Higher dimensions==
Rin explains how Higher Dimensions in the Nasuverse function, higher dimensions view every facet of the lower dimension like a book, in such a case higher dimensional beings and higher dimensional constructs are ontologically superior to lower dimensional beings and constructs within the nasuverse, BB who obtained a higher dimensional perspective was capable of viewing all of linear time and all of the multiverse within the mooncell as a book and can see the entire past, present and future of lower dimensions consequently,
Within the world of Tsukihime it is explained that a certain character by the name of Kiara gained higher dimensional senses, which was enough to make her omnipotent in lower dimensions but because her physical body was still lower dimensional, she was at the mercy of true higher dimensional beings thus returned to her lower dimensional self and losing her higher dimensional senses as well.
==Cosmological Scale#2==
===The mooncell===
The moon cell is a supercomputer created by aliens /non-human intelligent life, it consists of 7 layers getting past all of them gets you to the moon cells core, The moon cell was made to observe and record everything in earth and about earth since its very existence.
S. E. RA.PH on the other hand is an artificial world created by the moon cell, because it records earth which has infinite possibilities as information Aswell it holds infinite possibilities and if futures and infinite possible futures. 
Before moving on I went to preface this, there's a misconception that I want to address one of many about the nasuverse cosmology that is that the mooncell is just a computer and only contains data therefore it can't be used to scale. 
Although such an argument contradicts the context presented within the nasuverse itself and its more of a head canon then it is nasuverse Canon. 
BB explicitly explains the relationship between the mooncell world and the real world stating both notions are indistinguishable from each other stating the fights taking place within the mooncell can affect the real world and information, experience and power sources (e.g. BB's domino crowns which allows for her to manipulate reality) can get carried over to the real world. 
Demonstrating that power that one conjures within the mooncell or power existing within the mooncell is relative in power to the power you have in the physical the world should you decide to take such a power source to the physical world. 
Now that, such a misconception is addressed back to the cosmological scale of the mooncell the Sakura labyrinth doesn't have proper details on its cosmological scale so it won't be involved. 
====The wall====
The mooncell contains an 8 dimensional barrier blocking the way to the mooncells core, which is regarded as logically unreachable making it atleast 1-C.
====The core====
The mooncells core is implicitly said to be an even higher dimension making it likely 9th dimensional but nevertheless the mooncell in this state qualifies for 1-C. 
====Imaginary number of Space====
The moon has something called the far side of the mooncell, it is the source of poor information made up with complex numbers and is sometimes referred to as "the garden fall from the sky" within the far side and reality itself is made up of real numbers making it atleast Low 1-C possibly higher.
===Mooncells cosmological scale #2===
This part of more or less going over the mooncells cosmological scale varying on the continuity
====Special dog space====
In the events of extra ccc BB created her own space within the mooncell called the special dog space, Which was said to be infinite and endless making it atleast High 3-A.
====Cage of the Fallen====
In the seraph event within Fate grand order kiara created the cage of the fallen
Which boasted several extra temporal dimensions and beyond that of anything within the S. E. R. PH, At the very least beyond the standard Space-Time Continuum. 
making it Low 1-C.
===Earth and deeper textures===
Higher dimensions of the nasuverse become quite hard to gauge as a result of them not being definitively number; on various occasions but it shouldn't restrict us from using syllogism to present some sort of order in scale for them starting with. 
====The reverse side of the world====
Now this realm is where the gods and phantasmal beings retreated to after the end of the age of gods a realm incompatible with the laws and rules of humanity. 
This realm is clearly higher dimensional as its where the gods retreated to and the gods in question are said to exist in higher dimensions, not once but twice even Ishtar a goddess herself confirming that.
On the imaginary number of space in the reverse side of the world contains all possibilities. The imaginary number of spaces contains all logical coordinates. 
“logical space” is extremely frequent in philosophical discussions, yet one hardly finds any article or monograph dedicated to the notion of logical space itself, except when it is taken as synonymous with the space of possible worlds. Wittgenstein, who introduced the phrase to philosophy in the Tractatus, never defines logical space, yet we get a clear and intuitive idea of what it is supposed to be, namely, the space of all possibilities. If that is true, then we are immediately pushed to explain what possibilities are and what it means to say that logical space is the space of all possibilities. Traditionally, it is propositions that are taken as bearers of the modal properties of possibility, necessity, impossibility and contingency, and these modal notions are in turn explained by appeal to truth at a possible world. Logical space, then, is, according to current orthodoxy, a space of possible worlds, and possibilities are propositions true at some possible world, hence, belonging to logical space. Impossibilities will be propositions that are not true at any possible world; hence, they are not in logical space. Contingencies will be propositions that are possible but false at some worlds. Necessities will be propositions that are true at all possible worlds.
Considering no such thing as a logical coordinate outside computer graphics programming; that doesn't reference logical spaces, the imaginary number of spaces containing that entails it containing all logical spaces or coordinates is a term used to represent that. Logical spaces are ensemble of possibilities, these possibilities being logical possibilities.
Making the imaginary number of space of the reverse side of the world 1-T.
====Ontological Magnitude of Gods====
God's or divine spirits exist in there who are too powerful for Servant Containers and can only be summoned if they're heavily weakened. Which even then still places them at one of the top strongest among servants, meaning a god's existence as a higher dimensional being is qualitatively superior for a servant container, this is further proven as they state no matter how many times a servant ascends they can never reach the powers of divine spirits and God's, No matter how much you ascend a servant they're still incapable of reaching the level of divine spirits and God's, suppose X represents any arbitrary servant and Y represents any arbitrary divine spirit or God, then for all X, Y>X. Now suppose Even X ascended, x is now x^2, for all Y>x such that Y>x^2 as well. Humans are entire dimensions below gods. 
Magecraft itself is entire dimensions below the magecraft from the age of Gods and a fragment of a divine spirits power no matter how small is still above magecraft as God's are unreachable to magecraft of humans. This is important because it means God's can finally reach R^R because they're fundamentally superior to humans and extentions of the human world which is composed of {R^1,R^2,R^3...........upper limit | G } G-this unreachable formalized infinity is where God's would be 
This is how mathematically it would look like, therefore they're 1-B existing before the laws of quantum mechanics including the abstract infinite dimensional Hilbert space which foundate the human texture and the laws of physics inhabiting worlds of different laws.
Making a vast majority of gods atleast 1-B as they exist entirely beyond the texture of humanity which is 1-B with a few exceptions that are very powerful such as lostbelt 7 Kukulkan or Tezcatlipoca who are instead 1-T+ but that is another story for another day.
Reverse side of the world entirely 1-T.
==Inner Sea of the Planet==
====Avalon====
Inner Sea of the planet is an all-encompassing plane of existence, that encompasses both higher planes and lower planes of textures in the planet. It's a name made synonymous with Avalon, it is regarded as an unreachable utopia, that which whatever humans regard as paradise is a pure imitation of it Garden of Avalon. The celestial egg which exists in the inner sea of the planet, that which is what luminary imitates but by taking on a material form a smaller scale. It marks the beginning of the cosmos, or rather textures/universe in the planet.
User: Saber
Avalon, the Everdistant Utopia. The name of Excalibur’s sheathe, which also holds power as a Noble Phantasm. Aside from healing the user’s wounds and halting their aging, it also turns into a perfect fortress that protects against all physical interference when activated. Even in Arthurian legend, Excalibur’s sheathe is a “magic sheathe”. After Arthur received Excalibur from the fairy of the lake, he was approached by the wizard Merlin, who bequeathed upon him an enchanted sheathe. It is said that as long as he possessed this sheathe, he would not spill so much as a drop of his own blood. As such, it was even more valuable than Excalibur, and its loss to the machinations of his half-sister Morgan Le Faye is connected to King Arthur’s death. Fate/complete material II: Character material - Weapons: Excalibur’s Sheathe, p.119
As seen when weaponized, it is regarded as an absolute and perfected defense as a result of how unreachable the inner sea of the planet is to just about anything native to the planet. It's capable of blocking almost anything native to the planet and it's true magic in itself.
Making it 1-T+
==="The Universe"===
There's not much to say here there's "the universe" which encompasses everything here parallel worlds, higher dimensions, earth, other celestial bodies and galaxies or whatnot, however Roa states that there's no end to the path of omnipotence, no matter how transcendental you become there's always going to be something that lies ahead. He makes an example with Kiara from the Tsukihime timeline; who gained higher dimensional senses and functionally became all mighty in lower dimensions with her body still being bound to lower dimensions/this universe (texture of humanity where Roa is).
Despite having gained higher dimensional senses, because her body was bound by lower dimensions, she only saw a miniscule version of herself or how weak she was in higher dimensions due to how she was bound by lower dimensions physically and decided to relinquish her higher dimensional senses to live in lower dimensions. Tsukihime -A piece of blue glass moon- - Rainbow in the Night route - True End - Day 15: "The Blue of a Bright Day" 
This ontological hierarchy is specified to exist within the universe due to how its continuously ever expanding, even most God's who are already 1-B are not the pinnacle of this hierarchy, but they are subjected to the idea of an endless recursion of planes of existence which entails it growing all the way up to infinitely higher into Higher into 1-T+. Tsukihime -A piece of blue glass moon- - Rainbow in the Night route - True End - Day 15: "The Blue of a Bright Day"
And the universe functioning on a slightly similar principle to transfinite recursion.
==Beyond the Universe==
The throne of heroes
It is described as a higher plane of existence, it exists outside of the time axis and outside of time, outside of the world. 
The throne of heroes is said to exist beyond boundaries of space timeFate/Requiem - Volume 1 | Chapter 1 and is entirely dimensionless aswell implying qualitative superiority over space time making it Higher into 1-T+
By virtue of chain scaling earth has scaling to this as it holds authority which I already went over in Arcueid's page making it a Higher into 1-T+ feat. 
==Outer Gods Realm==
The realm of the outer gods exist beyond the laws and common sense and the universe itself, inaccessible to anything within the universe in the outer universe, outer gods exist in a world beyond reasoning they themselves seemingly can destroy aspects of logic, exist beyond logic and defy logic, with only a portion of their True power. The picture of Vincent Van gogh that contains the powers of outer gods can even swallow the world and it exists beyond logic and human knowledge. 
The outer gods themselves are described as being beyond the laws and common sense of the universe and are regarded as Incomprehensible even with limitless knowledge, higher beings from the outer universe outside of the conventional universe which in itself is Even Higher into 1-T+. 
==== The Ultimate Gate ====
The ultimate gate is tied to and represents all possible things and all dimensions and all-encompassing reaching across all space and time; which Sut-Typhon exceeds and encompasses. 
Even Higher into 1-T+
So I'd feel comfortable in stating outer gods are Transcendent+ atleast definitively with the consistency we get. 
==「　 」==
The Absolute—an indivisible force—transcends names and forms. It is known by various comprehensive aspects: the Akashic Records, the Spiral of Origin, and 「　」. The Spiral of Origin represents non-being, the nothingness from which all phenomena and concepts emanate. Within it, limits and the concept of impossibility lose meaning. As the source of all existence, it can create and record anything, surpassing all binary oppositions. It stands as the one true non-dual ultimate reality. 
The Akashic Records serve as an immutable repository of information about reality. They hold the essence of existence in an unchanging fashion. 「　」, the core essence of the Absolute, exists beyond predicates, definitions, categories, and limits.
