The factories and production plants were located on an island called Prime Coromon. This was where Incom mass-produced X-wing fighters and I-7 Howlrunners. Offices and barracks for the designers were located on Coromon Besh. Laborers were housed mostly on the Lower Coromon Chain. During the time of the Galactic Empire, these laborers consisted mostly of enslaved Wookiees, Yuzzem, and B'trillans. Other islands included the Northwest Coromons, Coromon Aure, and Lesser Coromon.
