Vanguard Station

Vanguard Station was Space station of the Sith Empire during the Galactic War. Following the death of Empress Vaylin and formation of the Eternal Alliance in 3631 BBY, the station was taken over by a group of Imperial defectors led by Major Korven as their base of operations. They began targeting and destroying nearby Alliance outposts, which eventually prompted the Alliance to retaliate and wipe out the defectors threatening them.
