Magic-Focused Talents for GURPS
These Talents are designed for campaigns where magic is both real and at least somewhat formalized. The Fortune-Telling skill in particular here assumes that divination works. Also: while there is no reason why the Witch and Wizard Talents cannot be bought by the same PC, in many worlds people look oddly at somebody who has affinities for both.
