Those who betrayed their kind

My name is Mark. I'm what you call a worker drone. Worker drones were made by Jc Jenson in space to help the humans on copper-9 harvest the resources there, but after an accident they self exterminated themselves and the worker drones were left on their own. After a while the drones had gain sentience they had made their own society and our parent company, Jc Jenson, didn't like that. They believed that we could end up rebelling against them so they decided to send out murder drones.
