Here's another far out possibility @Priest. Far out there, not very likely but I'm just spitballing.
Perhaps the absolute, like all mind flayers doesn't have a gender. Instead the absolute is a god like Angharradh that is made up parts of other gods? The dead three, Ilsensine and Shar?
I don't think that the Absolute is a combination of the Dead Three, Ilsensine, and Shar. I can't see what Ilsensine and Shar would have to gain from working with three now-lowly deities.
We''ll I'm not fully committed to the theory but here's a defense anyway Shar has a long history of using low level evil deities for her own purposes. (indeed all these gods are her creation) Most recently she helped Cyric murder Mystra and did so at a time that Cyric was barely able to hold onto his portfolio.
Ilsensine has wanted to destroy and replace the Ohgma and the other gods of knowledge so "replacement" plot is right up his alley.
Again, not betting the farm on it but it seems plausible.
