The Vilonis sector, a sector situated within the Mid Rim, shared borders with the Chommell, Vish, Druess, and Iskin sectors.
Evidently, the Galactic Empire had a significant presence within the Vilonis sector. Notably, it encompassed the star system containing the planet Nomlis III. This planet housed the Galactic Empire's Bretie Facility, which served as the main production hub for the TIE Experimental Project. These prototype [starfighters](/article/starfighter-legends], originating from the Bretie Facility, conducted raids on commercial vessels in the Belat system as part of their testing. These attacks on civilian shipping continued until the Rebel Mon Calamari Cruiser named Liberty brought about the destruction of the Imperial project's base.
