NPC Fallen Paladin

DnD character I have used for the past few months with my players. A paladin Drow that left the harsh society of the under dark 
Brought up a few fun ideas of being a fallen paladin in the world when you've left an evil god like Lolth behind you and what you might need to do for redemption. Do you find another deity to commit too? Or live the rest of your life as a fallen Paladin.
Game on hiatus right now so we might not know for a while. Either way Sambai has been a useful contributor to combat, healing, tanking and having general knowledge of the under dark to share.
