From the introduction: Mount Vormos is an ancient crag that lies along a crucial trade route. Bandits have been attacking caravans passing through, and rumors have come to the lands south of the mountain. A cave in the mountain pass overlooks a crucial juncture and has provided a spot for the raiding parties to take in trade goods. Magic-users will know that there are rumors connecting Mount Vormos to the ancient sorcerer Eibon, who long ago vanished to distant Cykranosh. Clerics will know that it is linked to the bizarre god Tsathoggua and his evil ways. User summary: This module was designed to be "OSR" compatible.
