Canon Sathar: Alpha Dawn file #3
History...Then the sathar appeared. No one knows where they came from or why. They attacked and destroyed lonely systems on the edges of explored space, moving slowly inward. Survivors described the sathar as wormlike creatures 3 to 4 meters long. That was all that was known about them, because they would rather kill themselves then be captured. As the danger increased, the humans, dralasites, vrusk and yazirians formed the United Planetary Federation (UPF) to defend their worlds. The mysterious sathar were forced back, but before long they returned in a more sinister form.
The sathar had learned that they could not beat the UPF in battle. Instead, they began hiring yazirian, dralasite, vrusk, and yazirian agents to sabotage interstellar trade and interfere with local governments.

Slavebot Description
Slavebots were created to guard sathar installations. Slavebots are cybernetic combinations of living beings and machines. The biological part of the slavebot is the remains of a captured enemy. Most of the brain has been replaced by a cybernetic implant. The slavebot is controlled by a disembodied sathar brain kept in special liquid solution. The brian is almost immortal since there are no other body parts to age. The sathar brain is linked to a radio transmitter that sends coded signals. These are then recieved by the slavebot so that direct control is possible. The slavebots on Volturnus are eorna captured in the battle that nearly wiped them out. A supply of captured victims is kept in cryogenic storage to provide replacement for worn out slave bots.
