So the question I'm trying to ask here is, is Anu the Amaranth of Aetherius and did the e'tada try to collectively steal the dream of Anu to become the Amaranth of the Mundus? Mundus is a dream seperate from Aetherius right? Seeing as according to Magna-Ge pantheon the e'tada actually have societies in Aetherius and it isn't just stasis? So Mundus is just a subgradiance of Aetherius could Aetherius be a subgrandiance of another dream in which Anu was a mortal and stole the dreams of his dreams godhead and so on and so forth? Or is Anu the Godhead the be all end all?
All dimensions that encompass the Aurbis are part of Anu's dream. This means that the Magna-Ge, Daedra, Aedra, and mortals are all part of it, along with their planes of existence.
