Okay, so as I've done more research, my scaling is very out of date and doesn't reflect how big just the Umbra is, which I have only just finished due to it being so big.
Okay, So:
God is the Tellurian, which is literally everything, there's literally nothing outside the Tellurian, there's only the "Absolute Negation of Existence" that is the Void.
The Umbra is massive, and I mean even in an abstract sense, as the entire place is divided into 3 different areas which have multiple very large realms.
The Umbra is outside Time and Space as is.
The top of the Umbra, the High Umbra is the good stuff: This is where concepts exists, a Mage, the beings who can see into theoretically infinite dimensions cannot get here normally and cannot see much of this place.
So, with the bottom of the High Umbra we have the Vulgate which is a lot like the Warp, beyond even language, a collect realm of s╠Âe╠Âi╠Âz╠Âu╠Âr╠Âe╠ thoughts where everyone's happiest dreams could literally come true.
Libraries where books that were never written can be found, philosophical paradises in which abstract theories like Communism and anarchy really do work the way their proponents say they should work.
"If you took the analogy of Plato's cave (which actually exists here, by the way), where people see the shadows cast on the walls and believe it's reality, the Vulgate is where the watchers start to turn away from the wall and begin to see the things casting those shadows."
Then moving up there's the spires:
Literally infinite sized mountains of rising abstractions, with them being above the Vulgate "peaking upwards into infinity", The realm for higher consciousness, the spires themselves are not physical (yet are?????) and you cannot climb them normally with physical strength and to climb them one must use their mind (even though you're using astral projection to get here, you need MOAR MIND!)
Then at the top of the Umbra, where the freaky stuff happens:
"Realms in name only, the Epiphamies are regions too abstract and ephemeral to the even the lower tiers where the constructs of reality lay. The mysteries of the Epiphamies are too transcendant for the Mages to percieve for more than a few moments, with it being a mere fragment of the true realm. The place where the Archetypes exist.
"There are said to be Realms within this domain where mortal minds cannot go at all ― regions too transcendent for human consciousness to grasp.""
(Yes, there's Conceptual Archetypes)
Leaving the peaks of the Umbral realm, and going down instead:
We get the Afterworlds: Where the Infinite Heavens and Hells exist, for every variation of these realms exist, in every interpration of said planes exist. The Place where Humans go upon death. (Sometimes, the low Umbra is also another place where they go), the realms are shaped by mortal minds, and for everyone's own interpretation of the realm, exists here.
We know there's an infinite amount of them here, because there's actually an infinite amount of souls...in all heavens and Hell.
I have no idea how.
Umbral Courts: Basically the same as the Afterworlds except instead of being made from Mortal minds it's made from Angels, Demons and god's (As in the Pantheon gods not Capital G God, they exist too)
Their realms are made as they like them, in any way.
(Skipping the Deep Umbra, because I need to find out what the hell the Horizen is because THATS another thing. I'm skipping the Astral Doorways because it's basically the metaphorical Mind elevator to the Umbra and the Astral Penumbra because all the Penumbra are weird and
Moving into the Middle Umbra we get the:
Pattern web: Basically the thing that holds the verse together, this might have been referenced in Demon the Fallen when God (Capital G this time) stress tested is and the caused the Angels to develop a Race wide anxiety disorder.
In the Middle Umbra is basically the most normal part of the Umbra.
(Skipping the Spirit Panumbra)
Airts and Moon paths: Basically how the Umbra tells you to get out and stop being lost in it. It will develop paths, signs and literal signs to get you out of it.
Umbral Realm (Not Umbra Realm, Umbral): Where all the Afterlives and Godly Pantheons exists like Hy-Brasil, Dystopia, Olympus, and Kun Lun. There's also different realms like a Universe where the Dinosaurs rule, Universes of pure Forests and Universes of literal Factories.
There also exists MORE Heaven and Hells but not the conceptual ideas of them like in the Upper Umbra, these are more so the fears of said places and so they exist here.
The Aetherian Reaches and Anchorheads:
Basically where there's loads of Mountains reaching into "the sky" where glittering stars and Planets are hovering. This is where the Thunderbirds live from Mythology.
Then we get the Low Umbra:
The realm of Collective edge, where everything is dark, edgy and basically where gods (Not Capital) go and sit when they want to pretend to die.
It's also where the Vampires go after Death and where conceptual ideas and laws go to die as well. Somehow.
Oh yeah, and the Mages, they're the descendants of beings the Demons were turning into Gods equals and have tapped into that potential once more and are able to use a very very very very small portion of God's power.
So the conceptual realm is that transcendant.
So, to recap
God >> Angels>>> Tellurian >>> Umbra >>> Infinite Heaven and Hells (Everything past here is beyond space and time)>>> Infinite Multiverse >>> The Tapestry (A Singular Multiverse/Universe).
