Monte Cook Games Launches Dual-Genre Megadungeon Crowdfund for Jewel in the Sky

Monte Cook Games' first-ever megadungeon for the Cypher System has already raised more than double its $50,000 funding goal just days after launch, a sign that the concept bridging dungeon fantasy with space opera is finding its audience fast.

Jewel in the Sky centers on Vocurro, an eight-mile-long island floating 1,000 feet above distant mountains. The island is laced with deposits of inveigh, a gravity-defying mineral that powers airships and mystical devices, and is home to the Crystal Cathedral: a layered megadungeon packed with traps, hybrid tech-magic creatures, and an ancient history tied to the Visitors, spacefarers whose remnants are woven into Vocurro's deep subterranean ecosystems.

What separates Jewel in the Sky from a conventional dungeon drop is its dual-genre engine. GMs can run the same campaign as a high-magic fantasy crawl with kaiju-scale threats and treasure, or reframe it entirely as a science-fiction reclamation mission where agents recover alien technology from a primitive world. The Cypher System's flexible, fiction-first design makes that tonal pivot remarkably low-lift, and Monte Cook Games is betting the dual-use appeal broadens the book's value to groups that couldn't otherwise justify a single-campaign sourcebook.

The BackerKit campaign, which runs through May 1, 2026, offers entry at $19 for a PDF, $49 for a VTT edition, and $54 for standard print plus PDF. A deluxe boxed edition expands the package with poster maps, player handouts, character sheets, physical timers, and card decks. Backers who still need the Cypher rules can pick them up through the same campaign; a new edition of the Cypher System is due this summer, with copies set to ship ahead of Jewel in the Sky's main delivery.

The launch is part of BackerKit's coordinated Megadungeon Month, a cross-publisher event that brings together Goodman Games, Kobold Press, Troll Lord Games, Ghostfire Gaming, Loke Battle Mats, and Rowan, Rook & Decard, among others. Cross-project stretch goals reward backers who support multiple campaigns, a structure designed to encourage pledge stacking across the entire lineup.

Monte Cook Games also addressed one increasingly fraught production question head-on in the campaign copy: "You might encounter an AI in dank corridors of Jewel in the Sky, but we'll never use generative AI to make any of MCG's products."

For Monte Cook, the project is also a kind of homecoming. He and co-founder Shanna Germain launched Monte Cook Games in 2012 with Numenera, a science-fantasy setting that also played in the collision between magic and technology. Jewel in the Sky revisits that same territory in megadungeon form, arriving as the studio simultaneously develops a new Numenera edition and fresh Cypher System corebooks. With the campaign already past $119,000 and three weeks of pledging still to go, the dual-genre formula appears to be making its own argument.
