From the introduction: The party is summoned to Berdusk by Mayor Griffith Hawkins. The trade city is haunted and only brave heroes can save it before it’s too late. The adventurers are thrust into spooky encounters, fighting a variety of undead. The featured encounter occurs at the local tavern where the party must fend off a siege of vampire spawn. The players will ride a wagon to Berdusk, meet with the mayor, rendezvous at the Tiefling Twister tavern, fight off hordes of invading vampire spawn, and take on the responsible powerful vampire lord.
