Curse of Strahd
The Witch Hunters are an informal brotherhood bonded by a desire to root out evil spellcasters, druids, witches, undead, dark powers, and the bestial lycanthropes. The most famous is Rudolf Van Richten who before he died wrote a series of guides to the different forces of evil that Witch Hunters hate.
Consider Inquisitor_Background.pdf as a background for a witch hunter. Change the fluff around Avacyn for Lathander and swap out artisan tool for a language.
