Uncaged: Faces of Sigil
Sigil’s shops, factions, and streets are home to fiends, celestials, spies, merchants, and other dangerous figures whose true loyalties are rarely obvious. This 128-page sourcebook presents more than 40 characters and groups for use in Planescape campaigns, with histories, motivations, secrets, game statistics, and full-color art. The entries are linked by relationships and shared storylines, bringing the city’s inhabitants into a connected web of intrigue. Featured figures include a renegade dabus, a shadow elf with multiple faction identities, a tiefling who sells keys to portals, a githyanki mapping the Lady’s Mazes, and a gang seeking to revive a dead god.
