Ostfrei was a moon of Genarius. The moon was very dark, with its unique orbit keeping it in the shadow of Genarius most of the time. Its thick atmosphere prevented most of the light that the moon did receive from reaching down to the surface. Ostfrei was habitable at one time, but when Oblis was destroyed, Ostfrei was close enough to be affected. Asteroid impacts from the destruction started a seismic chain-reaction which left the moon uninhabitable.
