Question, can the illithid tadpoles transfer a dead mind-flayer's "self" over? I started another play, and the cinematic shows lots of bodies already inside the nautiloid, which the main Illithid pays attention to (Including one propped up against Lae'Zel's pod). Later when the dead Illithid is interrogated about the absolute, the description is a group of Mind Flayers, I wondered if there was a connection, it could explain why the Absolute is after the fugitives from the Nautiloid, the Illithid there could be opposition to the Absolute, also why Raphael is so interested and showing up here and there.
There seems to be a small "altar" for Lolth in the underdark, next to the lost gnome, normal candles, Lolth's candles, floor has a circular pattern. Might be nothing.
