Krampus Run

From publisher blurb: Krampus has come to the town of Kaldsten, leaving terror and despair in his wake: can you find him, rescue the kidnapped children, and prevent him from striking again? Krampus Run is the first official adventure for Dungeons & Delvers: Black Book (and the first adventure Melissa has written, so that's a milestone for her), but also easily compatible with other d20 games based off the original role-playing game. As the name implies it deals with the demon Krampus: he's abducted some children from the village of Kaldsten, and you get to go hunt him down on a monster-infested mountain. Better hurry: the longer you linger, the more children will vanish, perish, and be transformed into hideous monsters that you might have to fight.
