Mind you: this is a second-hand product! It is in very good condition though.
This supplement is for the GREYHAWK campaign setting, the first since the world-shattering GREYHAWK Wars boxed game. Descriptions of Rary's desert fortress in the Brass Hills are here, as are statistics on his co-conspirator, Lord Robilar. The back-breaking mines of Abbor Alz, home to the duergar, and the Ghost Tower of Inverness are detailed as well, along with dozens of other places, things, and persons. A four-color poster map of the Bright Desert and its surroundings is also included.
