Last page of the Amaranth thread talked about Magnus fleeing through the sun as flying into 'anu or anu's dream'.
Theory: Yes (specifically into Anu). Magnus fled from creation, into Anu the Everything. he was NOT, and zeroed out. This is why Magnus seems absent even when he should be present: in the Magne-ge Pantheon, he's been replaced with the Chrome Device, for instance.
Speaking of Aetherial life and zero-summing,
Literally just throwing an idea out there. Someone who's been paying more attention come shoot this down.
