The Auntie Ethel dialogue is mentioned in my first post on page one with most of the other known hints.
Ioulaum is an undead elder brain from netheril, we had a theory about him being the absolute but he is not evil
Shar plays some role in this, just as the fallen followers of Selune. I do not know how Myrkur fits in, his symbol is on the absolute amulet


I sometimes use thought experiments. I don't necessarily believe in every idea I post for discussion on this forum
