Rugar Lazarus was a trained medic in the Cadian 47th regiment, until he killed his CO, XO, and all other officers he could find. He has refused to speak of the "terrible occurences" in his earlier life, even when threatened by Coletrane. Prefers to use a boot, presumably stolen, to settle arguments. However, he feels pain at a far reduced rate to any human, presumably a side affect of him injecting himself with his own chemicals every time he was wounded.
