Gerion is a star system located in the Mid Rim, anchored by a single M-type supergiant star. The vast stellar output shapes a rugged planetary arrangement starting with Gerion I, a heavily scorched molten planet in close orbit. Gerion II features a desolate, airless surface with a single moon, positioned just interior to a prominent rocky asteroid belt. Farther out, Gerion III orbits as a massive gas giant harboring a extensive satellite system of fourteen moons. The outer orbital zone contains the corrosive atmosphere of Gerion IV, an extensive icy asteroid belt, and the frigid planetary body Gerion VI.
