paladin, arbiter, or inquisitor who violates his moral code severely enough will, after several warnings, lose the grace of the power that guides him, becoming a fallen knight. Fallen knights are totally unable to use magical abilities, gain no experience, and are reviled by their former foes and allies alike.

In order to regain his good standing with his deity, a fallen knight must first mend his ways by restoring his alignment. Only then can he seek out a suitable spiritual guide who will help him to meditate upon his sins and find his true path once more. His guildmaster is a good place to start.
