The Tomb of Harven Half-Skull

From publisher blurb: A hundred years ago, the pirate king Harven Half-Skull was buried with his ill-gotten booty in a secret tomb. Your band of adventurers have a map that claims to show the final resting place of the pirate king, and you're off to claim his loot. But the dead do not rest easy... The Tomb of Harven Half-Skull is an adventure for 3-6 characters of level 3-4, and is a classic dungeon crawl designed to be completed in a single gaming session.
