Long ago, in the land of Flanaess, an evil demoness founded a cult dedicated to exploring evil in its most elemental forms. This cult was based in a temple just outside the village of Hommlet in a vile shire known as Nulb. Soon, this cult ruled the region with tyranny; times of chaos and violence ensued. Hard-fought battles were waged and the war was eventually won by the good armies of nearby lands. The temple was razed, the villains were imprisoned, and order was restored. The temple itself faded into distant memory... until now. Recently, bandits have begun patrolling the roads outside Hommlet and wicked forces are rumored to be afoot, converging on the ruined temple at Nulb. Their purposes for such meetings are as yet unknown. The identity of these people are equally a mystery. Some claim they are bent on slaying monsters and maintaining order within the region, but no one can be sure. So begins your adventure within the Realm of Greyhawk. It is an adventure that will lead to the source of a deep and abiding mystery, to the very core of evil itself.
