As the name of the module implies, each of these mini-adventures is designed to focus on a unique treasure in the World of Greyhawk. Such treasures include the Helm of Selnor, the Eye of Nyr Dyv, the Face of Xenous, and the Sword of Azor'alq..
The module was published by TSR, Inc. in 1992 for the second edition Advanced Dungeons & Dragons. It bears the code "WGR2" and contains 19 short adventures set in various locations throughout the World of Greyhawk. The storylines of the adventures are loosely connected. During the various adventures in the book, players can, for example, explore the home of the archmage Bigby, invade a dragon's lair, travel to the demiplane called The Great Maze of Zagyg, and trade riddles with a sphinx.
Reception
Keith H. Eisenbeis reviewed the module in the March/April issue of White Wolf magazine. He stated that anyone could find use in it and that "This product is certainly worth buying for those who run Greyhawk campaigns and can be fairly easily adapted to other similar campaign worlds such as the Forgotten Realms."[2] He rated it as a 3 out of a possible 5.[2]
