Christophsis was a sky blue-colored planet in the Outer Rim Territories, in the Savareen Sector. In the earliest days of Christophsis, asteroids commonly crashed onto the surface of the planet, but after it was inhabited by the Christophsisians, they protected the planet from them and turned it into a mining hub. Their capital city was Chalcydonia and other species including Rodians, Kerkoidens, and humanoids also inhabited the planet. A while later, the Droid Armies of the Retail Caucus invaded the planet, and the Republic responded by sending an attack force to free the planet.
