Bast Castle
located on the planet Vjun, Bast Castle was built as Darth Vader's personal retreat during the height of the New Order. Like the surrounding landscape, the exterior of Bast Castle was dark and forbidding, with only two entrances. The front entrance was heavily guarded by automated defense systems, while the rear entrance forces invaders to scale nearly vertical stairs in the midst of some of Vjun's worst weather. These stairs spiraled into and out of the rocky cliffs, and footing at the higher levels was made more treacherous at the temperature dropped below the freezing point. The central structure of the castle was domed and heavily armored, with a tall tower at its center. In stark contrast to the castle's exterior, the polished stone floors and walls were kept warm by a combination of geothermal and automated power sources. Hidden within the walls of the castle were two of Vader's most prized possessions: the Jedi Holocron of Asli Krimsan, and the lightsaber used by Obi-Wan Kenobi at the time of his death. After the Battle of Endor, the castle was controlled by Imperial supporters who had learned of its location. The reborn Emperor Palpatine - living in one of the many clones grown on Byss - used the castle as the headquarters for his Dark Jedi. Sedriss was the first to occupy it, and erected a large, black statue of Vader in one of the castle's anterooms. With the continued growth of the New Republic and the loss of power by the Empire's remaining supporters, Bast Castle was eventually abandoned in favor of more strategic - and more hospitable - locations. Its location, and the rumors of Kenobi's lightsaber, came to the attention of Jedi Master Tionne some years after the death of Grand Admiral Thrawn, during one of her missions to seek out Jedi lore. She obtained information on Borgo Prime, as did the mage known as Orloc. Both reached the Castle at about the same time.
