I have have Half-Orc Cleric named Reverend Hul Trunton. His background is a Cloistered Scholar. His story is that he was born rich, but learned to hate the violent ways of his people, and after a wizard came through his village one day, he realized the power of study. He liquidated all of his assets and left. He spent days on end studying, until he came learned the power of the gods. He became a Life Cleric, and dedicated his life to good.
