After fighting Acererak in the Tomb of Horrors, the group meets a messenger form the Blackbournes asking them to deal with a local threat. Children have been disappearing from the area around Skull City, and a necromancer has raised the ancient Blood Tower. The fearless friends enter the base of the tower and fight of ghouls and popcorn undead to reach the top of the tower. The y find three portals, one to the top floor of the tower, one to what smells like a tropical island, and one to the Shadowfell. What will they do? Where will they go?
