Vampyre Hunter

"You stand at the outskirts of a small village, high in the mountains of eastern Europe. The townspeople have fled, for a vampire has taken up residence in the old castle nearby. Before they took flight, they managed to get a message to you. You're well-known in certain circles for your knowledge and expertise concerning esoteric lore. Only you can find and destroy the vampire. If you succeed, the villagers will be grateful. You find the mere existence of such evil repugnant; you will dispatch the vampire, you tell yourself."
