Copper 9

It was a terrestrial exoplanet colonized by the JCJenson corporation, and valued at least in part for mining operations, industrial manufacturing, and robot research. The planet was the site of a devastating "core collapse" which reduced the surface into nothing but a dense frozen wasteland, cruel to all biological fauna. It is now the current home of the "rogue" Worker Drones that were left behind in the wake of the biological extinction event, along with at least three known Disassembly Drones sent by the AbsoluteSolver to exterminate all Worker Drones.
