Thomas Valley

Thomas is a forever dungeon master who has been organizing or running events at conventions for over 40 years. He’s the co-founder of GameConclave, a convention services company and one of the Premier Organizers for Wizards of the Coast’s Legends of Greyhawk organized play program. GameConclave has produced more than 30 of the program’s adventures, from single-table mysteries to multi-table Specials, and runs them at conventions from Orlando to Madison. Seven were published on D&D Beyond in 2026, with three more arriving there in February 2027. His first novel, The Bride of the Hollow Maw, is a romantic adventure set in Turtleback Cove, a harbor town in the Lordship of the Isles. It’s a free download at gameconclave.com arriving November 2026. Thomas once played pinball with a young Luke Gygax at the Mecca Center in Milwaukee, and will happily brag to anyone that his RPGA membership number only has 5 digits.
