Copper 9

It's not like we revolted and killed all humans or anything, mostly because they handled that just fine all by themselves...

Copper 9 is the name of the exo-planet which serves as the main setting of Murder Drones.

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 to a frozen wasteland, lethal to all biological fauna. It is now the current home of the 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 company on Earth to exterminate all Worker Drones.

History

Before the core implosion

Copper 9 appeared as a habitable planet, at least capable of sustaining human life. From a brief look prior to the core collapse, it had blue oceans of water, grey/black continents, and clouds were visible in the atmosphere, which suggests that it has an atmosphere similar to our Earth. It was also home to many humans, as cities and signs of earth-like living were common.

Core implosion

Upon the core implosion and resulting explosion, a massive glow appeared for a moment before a massive amount of debris was flung away from the planet, and, most likely, a massive crater or even hole down to the center of Copper 9.

After implosion

The planet is covered in snow, and all liquid water is gone. Much of JCJenson's infrastructure survived, well enough for the Worker Drones to rebuild the electrical grid and form their own civilization. There are many skeletons of past humans around populated areas, and ice & snow accumulation is high. The bodies are buried within the snow.

Trivia

• The planet is a neighbor of a rocky planet with an enormous ring system, similar to Saturn's ring in our own Solar System.
• Copper 9 appears to have a moon similar in appearance to both the ringed planet and our Earth's own moon.
• It's possible that the planet was home to many different races of humans and not designated to one particular race. We can see this as one of the Worker Drone user manuals was printed in English, Russian, and French.
  • Doll and her parents both seem to have some sort of Russian-based heritage with both names and clothing. The fact that all the Worker Drones seem to understand Doll's Russian vocabulary also implies that Worker Drones were likely programmed before to understand and speak different languages besides English.
