I think I'm late. I personally think DCU cosmo should be high 1a.
A single universe inside Orrery is 11-dimensional reality, and due to nature of M-theory Grant Morrison published this
during seven soldiers event. This would be High 1-c but in the same comic, There are kind of entities known as seven men, Which exist beyond the whole universe.
Zatanna breaks 4th wall to access their realm. Solidly, this can be qualify as 1a since, she is hearing the voices from somewhere. In some ways it is similar to the
'I can see you' moment in Morrison's
Animal Man #19 where Buddy sees us reading him. Then,
Zatanna tumbles through the panel of Slaughter Swamp and into some sort of sub-basement of reality, within the machinery of the story. Solidly, this can be qualify as 1a due to
4th wall breaking.
Orrery would be 1a.
The God's sphere should be one layer deeper, as it represents the deepest level of the Platonic hierarchy, which is
the Absolute or Ultimate.
5th dimension and 5th dimensional entities would be 1 layer into 1a too. As they represent as
ink and pen of the Ultra comic.
The whole ultra comic is made up with Thoughts since Earth-33
which mapped in Ultra comic represent as Fictive Membrane.
Gentry were drawn inside the Ultra comic to corrupt and destroy dreaming of Ultra/Ultra comic. Things like fictive membrane
which support Ultra to edit the story doesn't work on Evil batwing due to 5th dimensional nature. Note : Comic books that exist in the universes are to corrupt the universes.
Not at all, anyone who read corrupted comic book got corrupt and become another comic book. Like,
Allen Adam getting view as a fiction, while he was reading Ultra comic.
Earth-42 JL getting view as a fiction, after they read Multiversity Guidebook.
Limbo, Monitor sphere, Hypertime and Source wall should be 1a too.
6th dimension also should be 1a due to Highest plane of existence in known Multiverse and
Beyond the 5th dimension.
Inside the Omniverse there are infinite multiverses created by the hands, the multiverses at least have
6th dimensions according to Guidebook. Theoretically, there must be more higher planes and
lesser Hands like Perpetua represent as 6d. So, I think only 6d hands can create 6d multiverse and according to Metron,
there's an cosmic ladder of hierarchy in the Omniverse, which also included entities like Perpetua. In this case, I personally think Hierarchy of cosmic ladder decide greater entities since Chronicler a functionary of the Greater Omniverse exist above Perpetua and below to the Source. Overall: Omniverse would be 1a.
The Source, which is the highest entity in the cosmic hierarchy ( According to metron ), transcends the rest of the cosmic ladder, including powerful entities like the Chronicler who are omniversal functions. The Light of Creation and the Great Darkness are in a stalemate, They should be High 1a
God/non-dual void would be tier 0. Since Non-dual void represent as
Omni-awareness and sublime to Supervoids which exist within Great Darkness and The Light and
a point where unspace and untime where one may silently observe... as God breathes in... and God breathes out. Exhaling his quintessence of perfection.
Note : Overvoid = Light = Presence = Light of creation, because
Source was directly meant to be Light of Creation. Source and the Presence are the same entity
which is the source of great energies and Overvoid and Source are the same. In the case of Non-dual Omni-awareness void, People will argue that " That Void is Overvoid and Overvoid is the Light in current run " but Morrison never wrote a single thing about Overvoid while writing about Green Lantern comic and claiming like " Presence is the supreme entity and beyond the Light " are like head-canons since there's solid statement that Presence is Source which is the source of great energies. Conclusion of that case, Light of creation would be aspect of God/Non-dual Void.
