Intro. The story takes place on an exoplanet called Copper 9, which belongs to the interstellar megacorporation JCJenson (In Space!). Years before the start of the series, humans were exploring the planet, but accidentally caused the planetary core to collapse. The result was a cataclysmic explosion that froze the planet and extinguished all biological life (humans). Worker Drones With humans dead, the robots that stayed behind — the Worker Drones — gained a consciousness of their own. They went from being corporate slaves to building their own society, with schools, families, and cities, living peacefully in the frozen ruins
