Secrets of the Enemy Capital
A d20 fantasy campaign setting takes place in Kerse, the so-called Enemy Capital hidden beneath, between, and behind the Nex. Dozens of races are caught in an ancient conflict for control of the city, a crowded melting pot where almost anything can be bought or found. The mysterious Caretakers have long encouraged hatred and distrust among Kerse’s factions, but their plans change with the arrival of the Horsemen of Balance. Characters navigate the city’s rival powers, uncover its secrets, and try to survive, alter the conflict, or escape.
