Treasure Crypt of the Salstine Pirate

From the publisher: The legend of the Salstine Pirate tells of a sea captain who turned pirate, killing off most of his crew and taking his treasure to land. Salstine found an abandoned tomb within the Dwarven Mountains to hide his stolen goods, and meant to stay there to avoid getting caught by the military he betrayed. However, what he found in the tomb was a horror that would keep Salstine trapped within forever.
