Corshia was a rouge planet discovered in PBD1810. It was positioned as a moon of Planet Boyi. Upon investigation, it was found that the planet was capable of sustaining human life. A strange atmosphere made the planet look like a black mass with a red stripe along the equator but underneath the disturbance is a winter planet, experiencing an ice age because it had no sun nearby as it travelled through space. With Corshia in Planet Boyi's orbit and having access to the dual suns, Corshia recovered and the ice age ended. Corshia has a diameter of 29,000 miles and is 65% covered in water.
