[ WP ] Describe a consistent , semi-scientifically system of magic .

Nanomachines exist everywhere in the world. They can build things on a microscopic scale, fight diseases, etc. 
 Anybody who can hack these Nanomachines, however, is on the same level as a god. If they are injured, they can easily heal themselves. They can use Nanomachines to kill somebody in plain sight, by going into their body and physically disassembling their heart, only to take control of motor functions, and make the corpse leave the room and dispose of itself, with witnesses not knowing he died in the first place. 
 They could lift huge amounts of weight, granting the user the ability to fly, or to telekinetically lift people and objects. 
 They could force somebody to fight for you by triggering series' of neurons in the brain, or prevent pain or fear from the user by doing the same thing.
