Have you guys considered that the Illithids are only kidnapping people for the absolute who are special? I don't know how much on this as been mined, but I won't mind as much every origin character being 'special', if it fits in with the machinations of the Mind-Flayers and the cult of the Absolute. Of course if that would also make a custom character's lackluster background a bit more incongruous.
I dunno ...
If you use Speak with dead on that noble (i think) in first "room", on fallen Nautiloid ... he specificly tels you that they were taking everyone and anyone. It was also seen in the cinematic intro, when those tentacles take litteraly everyone. :-/
But maybe there are those who will be simply turned into another mind flayer ... and there are those who will be indoctrinated as True souls ... to control and dismantle society from within, it sounds like good plan for conquering.
