D&D Greyhawk: Crown of the Witch Queen

Dungeons & Dragons will return to its Greyhawk campaign setting in 2027. Greyhawk: Crown of the Witch Queen is a new 160-page adventure releasing in the middle of 2027. The book will be the centerpiece of the Season of Sword & Sorcery (the second of D&D's 2027 seasons) and will be a villain-focused adventure featuring Drelzna, the vampire daughter of Iggwilv aka Tasha. Early concept art shown to press also revealed a look at Castle Greyhawk, perhaps hinting at a return to one of Dungeons & Dragons' most iconic megadungeons.

Drelzna appears in 1982's Lost Caverns of Tsojcanth as a final boss of sorts, guarding Iggwilv's treasure. She pretends to be an adventurer trapped by Iggwilv, charming those who enter the treasure chamber before fighting them to the death. In Greyhawk lore, it's assumed that she's eventually killed by exploring adventurers, as the Isle of the Ape adventure features Tenser mentioning that Iggwilv is "much wroth" at the death of her daughter.

Greyhawk was previously featured in the 2024 Dungeon Master's Guide as a sample campaign setting. Luke Gygax and Dan Ayoub announced that Dungeons & Dragons would be returning to Greyhawk in the near future, with Gygax leading development of a book called Melf's Guide to Greyhawk: The Shield Lands. No further update on that book was announced at Gen Con.
