Faith's Ashes (sorcerer version)

Once a trainee paladin, you were discarded and left for dead by those you most trusted. Now a sorcerer offers you an unusual route to power, and a deal. Will you hold to your beliefs and sacrifice yourself, even for those who abandoned and betrayed you? Or embrace the new source of power, at the cost of the person you once were? If you change the AI Instructions for this one, be sure to copy the last two bullet points over if you don't want your sorcerer returning to cliche cartoon villain mode.
