Jack of Harts

I designed the Peloran of my Jack of Harts universe to be the typical genetically engineered supersoldiers with an atypical twist. Their creators did not want the Peloran to turn on them and kill them like Berserkers, so they built genetic encoding into their brains that made them incapable of starting a fight without orders from their masters. Or in defense of their own lives. The last order their creators sent was to kill the race wiping them off the face of the galaxy, and the Peloran followed their orders to the letter. They killed the entire race. Every last one. They are the avenging angels of the Jack universe, great and terrible in times of war. But leave them alone, and they are the most peaceful neighbors anyone could ever want.
