The Salissia system, a star system situated within the Outer Rim Territories, served as the original homeland for the Human population known as the Salissians. As of 19 BBY, the Salissia system existed beyond the reach of the Galactic Empire's dominion in space.
The reference book The Essential Atlas, authored by Jason Fry and Daniel Wallace in 2009, marked the initial appearance of the Salissia system, locating it within grid coordinate T-5.
