Spire RPG: Conspiracy Handbook (EN)

Secrets and Lies in the City of Spire. This slim volume contains rules and guidance on making your own bespoke secret society using some of the non-player characters and locations detailed within. Characters such as: Cacophony Gryndel, an amorous widow whose hobbies include sponsoring revolutionary organisations; Brigadier Arneau Destera, a decorated war hero desperate to dethrone the Council; Maji Levecha, an unmasked high elf in charge of a non-Euclidian getaway elevator; Professor Margot Arkemton, a gnoll scholar visiting Spire thanks to some truly labyrinth visa permissions; Father Gavel, an itinerant priest of the god of Breaking and Entering; Captain Calvy Lejeune, a teenager who was put in charge of a city guard garrison as a joke. Each NPC has sets of tables packed with motivations, flaws, leverages, assets and associates to help build a scenario with an emphasis on investigation and player choice; once everything's set up, it's up to your players to infiltrate and subvert the organisation to their own ends.
Each character and location has been lovingly illustrated by Rowan MacColl.
