Bloodsuckers

From publisher blurb:

5th Edition Mini-Dungeon for four characters of level 8

The Countess Carmilla Mora died as she lived: as subject of rumor and scandal. Her decadent parties were legend, her conquests numerous, and her predilection for nocturnal rendezvous an open secret.

When her loyal retainers announced her passing away from a “disease of the blood,” gossip in the vicinity of Castle Mora ran rampant.

Then, creatures of the night began lurking about her crypt, and the market price for garlic skyrocketed. And as travelers across Mora County took to carrying sharpened stakes and holy water, vampire hunters began arriving in droves.
