This sourcebook contains 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 labyrinthe 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.
