While largely ignored or left out of the loop of modern civilization (other than frequent harassment from slavers) Datar was at one time the location of a Rebel Alliance Base. The backwater planet was advantageous to concealment and secrecy. However, in 0 ABY, forces of the Galactic Empire lead by Vice Admiral Slenn attacked the base. Their original objective was to obtain prisoners and information; but their surprise attack was thwarted and the rebels fought to the last man. It is unclear whether Slenn was killed in action during the battle or executed later by Darth Vader for incompetence and failure. Other than that brief battle, not many outsiders bother with this planet - or are aware of its existence.
