The setting includes a mapped Vertical Slum with factions, NPCs, locations, and adventure hooks; a gangland system for level-one domain play; new classes, skills, checks, hirelings, and equipment; 43 monsters; and an introductory vertical dungeon adventure. It also contains interior illustrations and interconnected chapter fiction.
