Between the years of 3 ABY and 4 ABY, Darth Vader, the Sith Lord, along with his confederates, initiated a campaign with the goal of annihilating a mobile fortress engineered by Governor Tauntaza. Tauntaza had withdrawn into this fortress to commence draining all vitality from the planet Gabredor III, intending to utilize the accumulated energy to fuel a suit of powered armor intended to oppose Vader. Despite Vader's belief that Tauntaza was an independent operative acting for the Crimson Dawn organization, she was in reality adhering to commands issued directly by Sheev Palpatine, Vader's own Sith Master and the Galactic Emperor.
