The Sadow'een were a secret order of assassins who served the Sith Lord Naga Sadow. During the reign of the Sith Empire, they were responsible for dispatching their master's enemies. At some point, they established a temple in the Glacial Fissure area of Hoth. The Sadow'een were responsible for killing Sadow's rival Horak-mul at the close of the Great Hyperspace War, though his spirit managed to survive. The assassins were entombed in the temple after their work was finished.
