Greyhawk (supplement)
Gary Gygax and Robert J. Kuntz wrote Greyhawk to expand the limited scope of original Dungeons & Dragons rules published by TSR in 1974. The initial game offered a small number of character classes and monsters, forcing players to own Chainmail for combat mechanics. This supplement became the first of five books released over two years to bolster those early limitations. Although the title referenced Gygax's home campaign, the book contained no details about Castle Greyhawk or its surrounding lands. Gygax believed new players would prefer creating their own worlds rather than using someone else's established setting. He stated that he assumed dungeon masters would want substance without window dressing since world-building belonged to the GM. His goal was simply to explain the rules used during long hours of play with his group. He did not intend to publish all material created for his players because he feared recouping investment on thousands of hours spent developing secrets.
The 68-page booklet introduced specific character classes like the thief and paladin that were absent from the original boxed set. It added new rules regarding weapon damage where each weapon dealt different amounts of harm during combat. Players gained access to spells extending up to 7th, 8th, and 9th level which expanded magical possibilities significantly. The text presented more types of treasure and magic items alongside a dedicated section for monsters. New creatures included lizard men, beholders, displacer beasts, blink dogs, and carrion crawlers. These innovations eventually became standard AD&D rules adopted by future editions of the game. The supplement bridged the gap between players who learned at Gygax's table and those picking up copies in hobby stores. Journalist David M. Ewalt noted this helped dungeon masters learn how to create adventures through concrete examples.
Greyhawk was already in process when TSR co-founder Don Kaye died in January 1975 before its release. The book appeared in early March under the designation Supplement I with product code TSR 2003. Artist Greg Bell provided illustrations after meeting Gygax while playing wargames years earlier. Bell sometimes responded to last-minute contact by copying figures directly from comic books pages. His cover art depicted a sword-wielding warrior copied from Dax the Damned by Esteban Maroto in a 1974 issue of Eerie magazine. Ready Ref Sheets published by Judges Guild in 1977 collected 20 pages of charts taken from Greyhawk and other sources. Material from this supplement along with Blackmoor and Eldritch Wizardry got revised by J. Eric Holmes for the Dungeons & Dragons Basic Set released that same year. A premium reprint reproduced the original content faithfully in 2013 with new cover art but unchanged text inside.
Lawrence Schick called Greyhawk the first and most important supplement to Original D&D in his 1991 book Heroic Worlds. Shannon Appelcline considered it an innovation because supplements were largely unheard of in the wargaming industry at that time. Games were frequently revised and reprinted but continually expanding a game was something entirely new during the mid-1970s. The Playboy Winner's Guide to Board Games reviewed the product as part of its broader assessment of tabletop gaming options. This work helped establish the concept that games could evolve through player adaptation beyond original rules. It demonstrated how a single group's home campaign could influence the entire hobby industry structure. Scholars recognized that the supplement set a precedent for future expansions rather than just serving as a one-time addition.
Details about the Great Stone Face illustration appeared only once within the dungeon corridor description titled Enigma of Greyhawk. Another reference mentioned a fountain on the second level issuing endless snakes continuously without stopping. These specific elements remained the only direct links back to Gygax's actual campaign world history. Material from Greyhawk along with Blackmoor and Eldritch Wizardry got revised by J. Eric Holmes for the Basic Set released in 1977. A second supplement named Blackmoor followed later in the same year after this initial release. The 2004 publication 30 Years of Adventure suggested details of the campaign were published here though Gygax had no plans to do so initially. He believed players would create their own worlds instead of using someone else's established setting. The book focused entirely on new game rules developed during long hours of play rather than narrative lore.
