Greyhawk - The World of Greyhawk Folio Edition (1980)

The World of Greyhawk Folio Edition (1980)

In 1975, Gygax and Kuntz published a booklet called Supplement I: Greyhawk, an expansion of the rules for Dungeons & Dragons based on their play experiences in the Greyhawk campaign. Although it detailed new spells and character classes that had been developed in the dungeons of Greyhawk, it did not contain any details of their Greyhawk campaign world. The only two references to Greyhawk were an illustration of a large stone head in a dungeon corridor titled The Great Stone Face, Enigma of Greyhawk and mention of a fountain on the second level of the dungeons that continuously issued an endless number of snakes.

The 2004 publication 30 Years of Adventure: A Celebration of Dungeons & Dragons suggested that details of Gygax's Greyhawk campaign were published in this booklet, but Gygax had no plans in 1975 to publish details of the Greyhawk world, since he believed that new players of Dungeons & Dragons would rather create their own worlds than use someone else's. In addition, he didn't want to publish all the material he had created for his players; he thought he would be unlikely to recoup a fair investment for the thousands of hours he had spent on it; and since his secrets would be revealed to his players, he would be forced to recreate a new world for them afterward.

With the release of the AD&D Players Handbook in 1978, many players were intrigued by the connection of Greyhawk characters to magical spells such as Tenser's floating disc, Bigby's crushing hand, and Mordenkainen's disjunction. The AD&D Dungeon Masters Guide, released the following year, also made references to the dungeons of Castle Greyhawk. Players' curiosity was further piqued by the ten Dungeons & Dragons modules set in Greyhawk that were published between 1976–1979. Several of Gygax's regular columns in Dragon magazine also mentioned details of his home campaign and characters that inhabited his world. Gygax was surprised when he found out that players wanted to use Greyhawk as their campaign world.
