An enemy of the Circle of Eight, "a group of powerful magicians dedicated to preserving the balance between good and evil", has captured one of the Circle's members, Jallarzi Sallavarian. The player characters become embroiled in the Circle's machinations as they try to rescue her. The characters move from the shantytowns of Greyhawk City, to the fortress-tower of the archmage Tenser, a member of the Circle of Eight who was slain some years ago. The characters will ultimately uncover a conspiracy which threatens the world.
