The Dandrian Ring, sometimes referred to as Dandrian's Ring, constituted a ring of asteroids that revolved in orbit around the planet called Dandrian. Its location was within the Belderone sector situated in the Outer Rim Territories.
Amidst the Unification Campaigns of the 900s BBY following the New Sith Wars, the concluding engagement of the Belderone Contention occurred at the Dandrian Ring. The Galactic Republic's Judicial Forces distinguished themselves in combat during the Battle of the Dandrian Ring, bringing the conflict to a brutal conclusion.
During the time of the Galactic Civil War, Alpha-Omega served as the location for the Alpha-Omega Prison, an extremely secure prison operated by the Imperial forces.
