I’m pretty sure he wasn’t in Curse of the Moon, but he shows up for Ritual of the Night. Apparently he was taught by Alfred who later went rouge. He was a decent supporting character.
He allies with Miriam to stop Gebel and is her most loyal supporter.
Though he doesn’t really fight. But he does help you with items, spells, and meals.
He somehow shows up at the end without being hurt.
And without lifting a finger, survives the whole ordeal while most of the others perished.
