Cities of Altered Earth: Octagon
A city guide to a sprawling mega-city built in the Western Mountains, where skyscrapers and pyramids rise above the ruins of the old city. The wealthy live in penthouse gardens while the masses struggle in Lowtown, and dangerous secrets lie beneath the streets. The guide details Octagon’s history and layout, provides encounter groups for its different districts, and describes the city’s prominent factions, including its spectacle-driven courts, elections, and corporate gladiatorial disputes.
