Star Wars: the Old Republic: Blood of the Empire

'After hundreds of years, the Sith Empire has returned to the galaxy, determined to crush the Republic that sent them into exile. For young Sith Teneb Kel, this is his only chance to rise above his lowly beginnings as a slave and prove his worth to the Dark Council. Yet their mission for him is unexpected. He will not hunt Jedi, but rather a fellow Sith who has betrayed the Empire-the emperor's apprentice!'--Publisher.
