The Denova system, located within the Ojoster sector, housed the planet of Denova. Because Denova possessed the valuable ore baradium, the Galactic Republic established a presence there. To safeguard the baradium mines from the Sith Empire, the Republic contracted a mercenary force called the Warstalkers. Ultimately, the Warstalkers turned traitorous, siding with the Imperial Army. An elite special operations team resolved this treachery, restoring the planet and its mines to Republic control. Subsequently, Denova and its surrounding system received increased military protection to prevent future incidents.
Decades afterward, both the planet and its system, along with its inhabitants, seceded from the Republic and joined the Eternal Alliance.
