prequel adventures to pave the way for the updated campaign setting. First, Roger E. Moore created Return of the Eight in 1998. In the adventure, set in 586 CY, the same year as the From the Ashes boxed set, the players meet the surviving members of the Circle of Eight, which is called the Circle of Five because it is missing Tenser, Otiluke and Rary. If the players successfully finish the adventure, Tenser is rescued from death, though he refuses to rejoin the Circle, and the Circle is reconstituted as Eight with the addition of three new wizards: Alhamazad the Wise, Theodain Eriason and Warnes Starcoat. Next, the Greyhawk Player's Guide, by Anne Brown, was released. This 64-page booklet moved the storyline ahead five years to 591 CY, and it mostly condensed and reiterated material that had been released in Gygax's and Sargent's boxed sets. New material included important non-player characters, a guide to roleplaying in the Flanaess, and some new sights. The list of deities was both shrunk and expanded; the thirty-eight non-human deities in the From the Ashes boxed set were eliminated and non-human concerns assigned to a handful of human deities, but the list of human deities was expanded from twenty-four to fifty-four. With the groundwork for a new storyline prepared, TSR/WotC released the new campaign setting as a 128-page source book, The Adventure Begins, by Roger E. Moore. Taking its lead from the Greyhawk Player's Guide, the new campaign world was set in 591 CY. Unlike the darker feel of From the Ashes, where the Flanaess was overrun by evil, Moore returned to Gygax's world of adventure. The Lost Tombs trilogy of modules—The Star Cairns and Crypt of Lyzandred the Mad, by Sean K. Reynolds, and The Doomgrinder, by Steve Miller—were the first to be published in the new setting. 25th anniversary of D&D The year 1999 marked twenty-five years since the publication of the original Dungeons & Dragons rules, and WotC sought to lure older gamers back to Greyhawk by producing a series of nostalgia-tinged Return to... adventures that evoked the best-known Greyhawk modules from 20 years before, under the banner 25th Anniversary of D&D: Return to the Tomb of Horrors, by Bruce R. Cordell, reprinted Gary Gygax's S1 Tomb of Horrors, and added a substantial expansion. Return to the Keep on the Borderlands, by John D. Rateliff, took Gary Gygax's 1979 module, B2 Keep
