Orologia can store
physical simulations.
inside his personality. Said simulation contains the Astral Realm, Sky-realm, and Otherworldly realm. But seeing how these can affect him I doubt this qualifies for qualitative superiority in terms of dreams/fictional and more so that he's just so large that simulations that involved these large realms are only as big as his personality and seeing there is an overflow this one falls under DontalkTD sample of limited capacity. (6D or possibly 7D)
The way this goes is that. Sky-realm is the assumed regular universe. Above it is the Astral Realm which exists on a higher stratum. (3D+time)
Between Astral and Sky-realm exists the
Dimension of Precipice, which
contains the Chronicles of Sky-realm's history in a river. where one
can reverse causality or as
Cosmos wishes can also strike someone from history. These are only supporting evidence as the main evidence is mostly as I explained earlier how the vestige of Astral Power/Primal Beast is already a higher dimensional existence even in their physical or astral power form that it causes someone who can see the entirety of spacetime as data have a data overflow. And since this place is subject to its own time separate from Sky-realm due to how
Sky-realm History is distinct from Astral-Realm History it is only right to assume that this place being built to try
being identical to Sky-realm would have its own time.
Furthermore, it is shown that some primal beasts to
some extent can simulate the reality of Sky-realm in
their dreams while also unaffected by it (4 spatial dimensions + time)
Otherworld/Crimson Horizon as explained is not just strong but also contains timelines from every dimension and as they are always superior to any dimension they enter and can freely tamper with the time and space within it as they are well beyond it. they were rated as another tier above mostly due to the description of being transcendental to space and time and being something that requires a power of another dimension of equivalent if not superior to harm it. (6D unknown if just spatial or has time as well something close to Orologia. But Orologia can resist them).
Normally they are powerless unless they gain a Vessel that connects them to reality.
furthermore, they cannot sustain reality on their own as reality collapses when nothing is left except for them
Etemenanki is a
structure that is neither Worldly nor Otherworldly and
encompasses Both Providence and Chaos but neither and could resist the encroachment of chaos should the boundary between these 2 spheres be destroyed It also has
measurements that contradict its exterior. I used to assume its superiority to the Otherworld aside from the Otherworld by itself cannot reach it. this works more like a Brane cosmology of some sorts
There is a Divine Realm but it hasn't been evaluated yet and hasn't been fully explained yet within the story.
I could make an argument for the Unchanging Principles that not even the Omnipotent can change and that they dictate even the nature of Omnipotent to be something that cannot be overtaken but it is honestly a loose one so I'll just wait and see till Anniv event or main story update
TLDR: Skyrealm 3D+time | Astral Realm - 4D+time (Low 1-C)| Otherworld/Crimson Horizon - Contains timeline of every dimension without order + Superior and can freely manipulate time and space (higher into Low 1-C) | Orologia being able to Contain them as physical simulation mass and can add more by using the Power of the Boundary to simulate more simulation (1-C) | Boundary being equated to Orologia's feat and various statements about beyond the bounds of dimension etc.
