From the back cover: Horror Stories Tsathogghua's curse awaits the unwelcomed investigators of the occult and unknown. What grim secret lurks on the sterile Greenland icecap? What living horror grows behind the "Bigfoot" legend? TRAIL OF TSATHOGGHUA contains a mini-campaign in two scenarios as well as a third, unconnected scenario -- "The Haunted House." This scenario pack is suitable for beginning keepers and investigators. It serves well as an introduction for the game and exposes new players to both the Cthulhu Mythos and the occult.
