ECLIPSE One-Page RPG

A WORLD OF ENDLESS WONDER AWAITS

From the makers of Stillfleet, Blister Critters, and PICARO!—a new take on rules-light low-fantasy adventure. ECLIPSE offers a blend of Old-School Renaissance (OSR)- and New-School Revolution (NSR)-inspired rules to facilitate fantasy tabletop roleplaying. It is compatible with any low-fantasy setting.

ECLIPSE One-Page RPG was created for One-Page RPG Jam 2026 >

Use, hack, and extend ECLIPSE. Create your own settings with new backgrounds and expertises for chancers as well as new spells, gear, and encounters. Run existing OSR adventure modules or create new ones using ECLIPSE.
