The Unioc are a race of one-eyed aliens in the Schlock Mercenary universe. The Unioc body structure is broadly similar to a humans, with the primary differences being skin color, three-fingered hands, and a single, enormous eye in place of the head. A Unioc's brain is located in its pelvic cradle.
Uniocs don't benefit from stereoptic parallax, but in many ways, have better eyesight than humans; the long focal length of the eye lets them see microscopic details, (such as a nanny-cam floating in the eye of a reporter) and they can gauge distance quite accurately by rapidly shifting focus.
The Unioc species comes from the world of Othlin, in the Xuvoth Star System. Othlin is generally Earth-like, but its landmasses make the world seem to resemble an eyeball, from at least one direction.
The Unioc home starsystem came under attack by the Pa'Anuri. The extra-galactic species attacked the Xuvoth starsystem, using its Hyperadvanced technology to rip one of Xuvoth's gas giants out of orbit, and compress it into a protostar. AI Petey and his galactic allies soon arrived and manage to destroy the Pa'Anuri. However, the Pa'anuri's destruction released the pressure on the protostar, causing a small supernova-like blast that threatened Othlin with extinction. Petey used his own hypertechnology to Teraport the entire population's minds and local Unioc ships' crews' minds into a virtual vault aboard the space habitat, Eina-Afa, while their bodies were left behind in cold storage for when the crisis had passed.
They have since been returned to their bodies after the end of the war with the Pa'Anuri, with their planet now spinning around its axis in the opposite direction, causing sunrise to appear from the "wrong" direction. Othlin's entire orbit has also now shifted, necessitating changes in the Unioc calendars.
