The Western Veil is a region of the Tau Empire. It was previously inhabited by the Arachen, a race which refused to join the Empire. As a result, for many years the Tau and Arachen battled over control of the Western Veil in the Veil War, with the Tau eventually proving successful in driving out their enemies.
