Bretheda
Bretheda's violent storms make most of its gaseous layers unlivable. The planet's largest city is Trillidiem, a domed, industrial arcology governed by Confluence, a union of many merged barathus. Bretheda's many moons include Kalo-Mahoi, an underwater utopia celebrated as the fashion capitol of the Pact Worlds; Marata, a warm, green world of peaceful anarchic communities founded by seven-gendered maraquoi; Dykon, the crystalline home of urogs that's recognized as a major academic hub; and radioactive Thyst, one of Bretheda's many mineral-laden death moons.
