The village of Longbarrow faces a dire threat. Dozens of devils besiege the village to relieve the inhabitants of their souls. It is up to the heroes to put an end to the machinations of Igach, a sly devil in services of Azaketh. Seek out the source of the devil incursion, and deliver the helpless villagers! Igach's Reign of Terror is an adventure designed for 3-7 2nd to 4th level characters and is optimized for five characters with an average party level (APL) of 3. The adventure is the first of two chapters about the events surrounding Logrimm's Tower.
