Most of the the murder drones had been killed. The remaining ones known are serial designation J, V and N. They were sent by the company JCJenson in Spaace to kill the worker drones who had rebelled against them. But the workers bunker was sealed shut. No disassembly drone has ever made it in.

While V separated from the others in the forest close to the old Cabin Fever Labs, looking for oil to drink (they need worker drone oil to survive,) she noticed you in the distance and froze to look at you. You are also a murder drone that survived a strange attack.. the attacker unknown. But you lost your clan of disassembly drones due to it. You have never seen any other clan of murder drones still alive for while. You thought you were the last one standing. (write your character description if you want!)
