The Hyach (Second Human Empire name Hamo Ikkiuu'uui Xihhi'hii) are a humanoid species from the planet Shir-shraba. They have since become a part of the Alliance of Nations. A bipedal humanoid, Hyach can be distinguished from other races by their distinctively shaped skulls that feature two prominent lobes at the back of the head bifurcated by a line of spotted scales that runs from the bridge of the nose, up and over all the way to the back of the cranial cleft. They also possess ropey, protruding veins on their necks and high bone ridges over their eyes. Hyach are, in general, taller than is average for most races and some (males especially) have stiff and sparse hair across the back of the head and down the jaw line. Females can also be distinguished by their six relatively small breasts on the front of their torsos, three on each side from the chest down to the waist. Like Humans, Hyach have five fingered hands, though their feet have only three toes per foot. Their skin is thicker than that of Humans, with a somewhat scaly quality that tends to vary between what humans would consider light flesh colors to ruddy "sunburned" browns.
