A device of Freon technology the Anuna got from the Freon that can be implanted and affects the Nerve system directly. The Controx comes in two parts. One part of the device overloads the nervous system with direct simulated pain impulses ( from mild to lethal) and the other part transmits visual and audio commands of the masters directly via eye and ear nerve into the brain to deliver commands.
The leaders of Anuna use these devices to enslave billions and make them Servlings. No matter how many slaves band together trying to fight or revolt, a simple impulse and they are all flooded with tremendous pain, or death impulses. Via the Controx a slave can be made blind or only see what the masters want them to see or hear. Revolution is impossible, rule is absolute.
