The Peroenians were a Near-Human species that originated on the planet of Peroenia, in the Unknown Regions. They had six digits on each of their hands and feet, and they also had long, yellow-and-gray-colored hair. The Peroenians were keen explorers and after they learned that the rival Shorak species had discovered the planet of Giaca, the Peroenians dispatched a number of expeditions to Giaca. The Shorak eventually attempted to establish a permanent colony on Giaca and the Peroenians sent a military force to ambush the colonists in the Giaca system, sparking a three-hundred-year-long war between the two species in which the Shorak were eventually victorious.
