The Naos Asteroid Belt was an asteroid field in which Dathka Graush, an ancient Sith sorcerer and King of the Sith Purebloods, had built a fortress. The keep contained vaults in which Graush stored precious artifacts. In the final years of the Cold War, a group of adventurers led an archaeological expedition to the asteroid belt in order to retrieve the treasures of Dathka Graush.
