Verrry interesting. Makes me reconsider a theory about the absolute I had previously dismissed --
perhaps Vlaakith is the mastermind after all. She sits on a throne of mind flayer bones and can leech mind flayer powers, she is almost certainly is responsible for Gith's imprisonment and Zerthimon is the one person other than Gith with the authority to destroy her plans. Namely to become a god to other races. Perhaps she is manipulating the mind flayers and collaborating the dead three.
