I just have a few questions about all of this;
Aetherius is where souls go to after you die is it the opposite of oblivion, so possible the creation of Anu?
After the creation of Mundus Aedra lost there immortality. So who created the Daedric princes Planes of oblivion if they're only capable of change? and why didn't they lose there immortality?
Could Aedra originally of came from Aetherius?
Mer where about before men, where these the creations smaller Aedra who gave themselves completely?
I'm sorry it's quite long and if any of it is wrong, and any mistakes could you correct me instead of being immature, thanks.
