Antes Belladar was the Human male governor of the agricultural planet Reytha during the reign of the Galactic Empire. In 0 ABY, during the Galactic Civil War, Reytha was taken over by the Alliance to Restore the Republic, which Belladar was unable to prevent. Eventually, he received assistance from the Sith Lord Darth Vader, who was able to eliminate the Rebels from several of Reytha's major cities. After Belladar discovered a Rebel presence in the Montrosa Islands, Vader led his army there. When he arrived at the islands, Vader executed Belladar for failing to prevent the Alliance takeover, and then eliminated the remaining Rebels from the planet.
