The Azziz are a humanoid species encountered by the humans in 2470. The Azziz have a slightly wider skull than Humans, and distinctive bone structures around the eyes. After contact, some began working for the humans on their colonies and served in the Earth force. The Azziz live within the territory controlled by the Fen Domar, who view them as predisposed to criminal behavior. Although they only comprise ten percent of the overall population, Azziz make up eighty percent of the population of Fen Domar jails. Azziz are also ten times more likely to be executed for a crime.
