The loyal champion of the Vaxia tribe, Kyban Vaxis Mordo is Chieftain Vaxius Domingo's most trusted praetorian. He is known equally as a deadly warrior and for his undying sense of duty to his tribe. His body was nearly destroyed in a battle with rebels, but has continued to serve the tribe with some of the most advanced replacement limbs Eronite priests could conjure. It is rumored that his head was so severely damaged that he cannot remove his headpiece, and that only the brain remains intact within.

What Kyban lacks in charisma and subtlety he more than compensates with a single-minded focus on his goals. He may be a blunt tool, but an extremely effective one when used correctly. This makes him and the chieftain a good pair. Vaxius is clever enough to use his praetorian effectively, and Kyban can always be counted on to fulfil his duties. When this imposing cyborg arrives people treat him with an attitude of respect and fear, something which Kyban secretly relishes.
