New Call of Cthulhu Adventure, Madness at Geneva Lake, to Debut at Gary Con XVII

Chaosium, in collaboration with GaxxWorx, has announced the release of Madness at Geneva Lake, a new Call of Cthulhu adventure that combines a lesser-known chapter of TSR’s history with a story of cosmic horror. Written by Alyssa Faden and Gary Con founder Luke Gygax, the 72-page softcover book will be available for the first time at Gary Con XVII, taking place at the Grand Geneva Resort & Spa in Lake Geneva, Wisconsin, from March 20-23.

Set in 1891 on the shores of Lake Geneva, the adventure explores a narrative that blends Chaosium’s Lovecraftian storytelling with the roleplaying legacy of Lake Geneva, the birthplace of Dungeons & Dragons. The project is part of Chaosium’s 50th Anniversary celebrations and highlights the shared history of the two companies in the tabletop roleplaying game (RPG) industry.

Luke Gygax, founder of Gary Con and son of Dungeons & Dragons co-creator Gary Gygax, commented on the collaboration:

Gary Con is a memorial convention that celebrates my father’s legacy and the enduring passion of the gaming community he helped create through Dungeons & Dragons. This year’s partnership with Chaosium as the Premier Sponsor of Gary Con feels like a convergence of history and creativity, bringing together two pillars of the RPG world to honor their shared dedication to immersive storytelling and imagination.
