In this scenario, the player characters are sent to see why communication with a distant barony has been cut. The module includes a complete description of the barony, a wizard's tower, and a village which has been taken over by undead.
A strange black cloud hangs over the Norworld barony of Two Lake Vale, which is cut off from the rest of the world. As the player characters move to investigate, they encounter armies of the living dead and other vile creatures besieging the last pockets of human resistance. The only relief is to find and destroy the dreadful Deathstone, which is responsible for the black cloud, thereby facing the united forces of an evil sorcerer, a powerful priest, and a mighty dragon.
