The Peroenians, a Near-Human species, hailed from Peroenia, a planet situated within the Unknown Regions. A defining characteristic was their possession of six digits on both their hands and feet, coupled with lengthy hair displaying a yellow-and-gray-colored pattern. Known for their adventurous spirit as explorers, the Peroenians, upon learning of the rival Shorak's discovery of Giaca, launched multiple expeditions to that planet. The Shorak's subsequent attempt to create a lasting settlement on Giaca prompted the Peroenians to dispatch a military contingent to ambush the colonists in the Giaca system, thereby igniting a three-hundred-year conflict between the two species, ultimately resulting in a Shorak victory.
Many millennia passed, and approximately twenty years prior to the outbreak of the Clone Wars, the Shorak once again established a settlement on Giaca. Reacting to this development, the Peroenians sent their own representatives to establish a presence on the same world. Despite several minor conflicts erupting between the two groups on Giaca, the Shorak ultimately succeeded in creating a permanent colony there. Nevertheless, the Peroenians persisted in their harassment, frequently staging attacks against the Shorak colony.
