One thing that was left out of the Magi, Psions, and Disciples, is that anytime you change breeds (Any breed requiring a Breed Change sent in to the CS Dept.) you gain Level 1 Lore, if you don't already have levels in Lore, and a specialty in your breed. So for instance, if you were a mortal without any levels in lore and became a Disciple, you would gain Lore 1 and a specialty in Disciples.
You cannot gain additional levels of lore with this, but you can gain additional specialties.
