The Omniverse is a container that contains everything that exists, making it transfinitely large. If we take the jump from our Universe to the Multiverse, and repeat it infinitely, we get the Omniverse (or rather, an approximate equivalent, but not the same).
The Omniverse has a fractal structure resembling random sphere packing. Unlike from the Apollonian gasket or Kleinian circle packing, the size and position of verses is random and spaces between verses exist.
However, many civilizations have created their own superstructures that hold thousands of verses of equal size revolving around a central one, or more. The Omniverse contains everything that exists, but the Omniverse itself doesn't exist, as to resolve the issue of self-containment that The Box undergoes.
The Omniverse is one of the most popular structures of this Realm, as it was chosen to be a hub for most deities, gods, creatures and civilizations (more on that bellow)
Alongside that, the Omniverse holds historical importance, as many ancient relics can be founds here, with hundreds of museums of artifacts from all over the Realm, libraries, community centers, governments, and research centers, that were all built here. Essentially, the Omniverse, along with The Box, are capitals of this Realm.
Back when The Box was created, it's recursive layers were not stable whatsoever. Many of them collapsed inwards on themselves and disappeared into thin air. This did nothing, because The Box was empty and non-finality based yet, but it had an infinite number of layers.
After a bunch of layers fell, one layer, which was either special in some way, or collapsed in the right way, or maybe a phenomenon happened at the exact same moment, it is unknown what really happened but we know it happened with the collapse of a layer, caused a massive explosion inside, which rattled The Box and turned it maximally chaotic for the next many, many OYC. During this stage of chaos, through sheer luck, The Box slowly brought upon itself the property of being 2-finality.
As this happened, objects of existence-(0,1) were first ever constructed. Then existence-2, existence-3 and so on. The problem is, that existence-4 and existence-5 objects attract each other (positive and negative attractions between icosahedra varients described in The Other Box article), and as two far apart ones and giant ones did so, they smashed together, producing an incredible explosion, blasting away the majority of all non-existence-(0,1) objects, and in the process, causing the formation of 12 Omniverses. 1 of them was special, containing all existence-0 objects, and so it was given the name of The Omniverse, while the others were named as Pseudo-Omniverses.
Another reason for its significance, and a deciding factor for it becoming labeled as special, and the other ones as mere "pseudos", was due to the absolutely unmatched amounts of Archverses packed together, which were not only patterned, but some also patternless, some had life, some were empty, some had ordered cubistic looks, while some were fractaled.
All of the 11 Pseudo-Omniverses, alongside with the Omniverse, are contained by the Allomniverse, but the verse is invisible in most visions.
Omniverse, in Aarex's cosmology, contains everything else, including (non-)existences, types, abstracts, and concepts. It proves the omniverse is similar to The Box.
Omniverse is part of Archverses
