There was the vampire doctor adventure set in Valachan too, the towun got snowed in so noone could leaveSounds like "Felkovic's Cat" from Dungeon #50. It was originally an RPGA adventure, and was basically a mini-gazetteer of the domain, and had full maps of the Castle Pantara (i.e. the darklord's lair). It was one of the best Ravenloft adventures in Dungeon, to my mind.
