Greyhawk campaign, Wizards of the Coast did not produce much material for Greyhawk after the 25th anniversary Return to... series of adventures and the Living Greyhawk Gazetteer: The Standing Stone, written by John D. Rateliff (2001), had several minor references to the Greyhawk setting. Red Hand of Doom, written by James Jacob (2006), was not set in a specific campaign world, but did contain instructions for where to set the adventure within Greyhawk, Forgotten Realms, and Eberron. Expedition to the Ruins of Greyhawk by Erik Mona, James Jacobs, and Jason Bulmahn (2007), was an update to TSR's 1990 release WGR1 Greyhawk Ruins. Otherwise, Wizards of the Coast left the development of the Greyhawk world to RPGA's Living Greyhawk campaign and concentrated on producing new source books of expansion material for the core rules of D&D. Fourth and fifth edition of D&D (2008 to present) Fourth edition At Gen Con 2007, WotC announced that the 4th edition of Dungeons & Dragons would be released the following spring, and Greyhawk would no longer be the default campaign setting under the new rules system. For this reason, Living Greyhawk was not converted to the new rules system; instead, it was brought to a conclusion at Origins 2008. In 2009, WotC released The Village of Hommlet, by Andy Collins, which updated Gary Gygax's original 1st edition Village of Hommlet to the 4th edition rules for characters of 4th level. It was not available for purchase, but was sent as a reward for those who joined the RPGA. In March 2013 the adventure by Collins was reprinted in issue 212 of Dungeon, but now for characters of 3rd to 5th level. Fifth edition When the Player's Handbook for the fifth edition of Dungeons & Dragons was released in 2014, several references to the world of Greyhawk appeared throughout the descriptions of various races and classes, and a partial list of Greyhawk deities appeared in the book. The Monster Manual, the second released book of the 5th edition, did not include any direct references to Greyhawk but did mention Explictica Defilus from Against the Cult of the Reptile God in the Naga entry, and tied the creation of ghouls to Doresain, the "King of Ghouls", from the Greyhawk adventure Kingdom of the Ghouls by Wolfgang Baur from Dungeon #70. In April 2017, Tales from the Yawning Portal was released. It contained seven older modules now reprinted
