"REDISCOVER THE BIRTHPLACE OF ADVENTURE!
The year is 591 CY. The World of Greyhawk has changed a lot, as nations topple and leaders plot. Whole realms are "lost"; others have crumbled; still others have advanced, becoming new powers in the Flanaess. So where are you going to find all the news?

Extensive histories of the Flanaess and the Domain of Greyhawk
A place-by-place description of the City of Greyhawk
A 16-page map booklet with new and updated maps of towns and adventuring sites in the central Flanaess
Updates on famous people - good and bad
The seeds for thousands of new adventures
