The Master Wizard
Powerful and driven by more power; Jim Darkmagic is a powerful wizard, long since retired from his adventuring days. No one knows why he split from his adventuring group, but one day he up and left, becoming all but a recluse.
Eventually he took a young Crowley Shadowmane under his wing as an apprentice. For years he taught Crowley the ways of Darkmagic, until his most recent disappearance.
