Thrope

In the modern-day Citadel of Omnia, he is the deaf old deacon who instructs candidates for the priesthood on demon-slaying and vampire hunting. The module in Revenants and Ungodly Creatures rates low in the theological studies heirarchy, meriting a mere hour every fortnight, and doesn't even count for the final exam. However, in Carpe Jugulum, Thrope's wisdom becomes an indispensible part of Mightily Oats' pastoral practice when he gets a parish in Lancre at a time when vampires are foolishly invited in by King Verence II.
