Surepp were animals herded by the Alwari clans of Ansion. They had three eyes arranged vertically, the top eye used to scan for aerial prey, the middle eye for looking ahead, and the bottom eye to search for food on the ground. This ocular arrangement gave very poor peripheral vision, but since surepp herds contained thousands of animals they had enough eyes to look everywhere. Their size and the number of their herds meant that predators rarely gave them trouble. They were popular among the richer clans, who used them for milk, meat, wool, and hides (in the past, their antlers and teeth had been used for toolmaking).
Male surepp had coiled antlers, blue fur, and dark neck ruffs; females were slightly larger, had green fur, and lacked ruffs. Less than one in a thousand were albinos.
