The whole absolute storyline does have a few little plot holes. Maybe Atlantis went missing in one of them?
More threads about it will increase the chances of Larian noticing
Lets see
The goblins want to kill you after helping them. So the absolute wants you dead?
Using the tadpole a lot the dialogue option illithid changes to true soul with the description "high ranking servant of the absolute"
Priestess Gut does not seem to know that she hosts a tadpole
The Goblins know that they are allied with the mindflayers
