I just noticed there's a talent tree for almost everything except "The Sage".
Granted the only thigns I Can think of right now are "Intellectualization" [intel test when reading books and stuff to avoid gaining insanity and corruption] and Fast reading.
Maybe Seen this before but modified to fit these new rules? Talented [specialisation] is also good. Maybe "Well Learned", can roll common lore even if he doesn't have a specialisation and "Fast Learner" Specialities cost half exp only.
Can anyone come up with more? That type of character needs a bit of love, he doesn't get much in this system.
