After the death of his previous Voice , the Emperor transferred his consciousness to the Human and gathered his strength on the Imperial capital planet of Dromund Kaas , preparing to perform the ritual of Sith magic that would allow him to consume all life in the galaxy . However , the Jedi Knight known as the Hero of Tython foiled his agent ' s attempts to start the ritual , and the Emperor used the Voice to battle the Jedi when the Knight confronted the Sith in the depths of the Dark Temple on Dromund Kaas — a battle that ended with the Voice ' s death . Biography . In 3641 BBY , during the Galactic War between the Galactic Republic and the Sith Empire , the Sith Emperor was trapped in his current Emperor ' s Voice — the host body for his immortal essence — when the Sith Lord Darth Baras lured the Sith ruler to the ancient ruins known as the Dark Heart on the planet Voss . The Emperor and his Voss host were unable to leave the Dark Heart , as the Ancient Halls of the Dark Heart were built in a way that prevented any Voss from leaving once they entered , and the Sith was forced to fight the dark side entity Sel - Makor for control of the Voice . However , the newest Emperor ' s Wrath , the Emperor ' s personal executioner , freed the Emperor by killing the Voice , and the Emperor ' s essence returned to the care of his servants in the organization known as the Emperor ' s Hand . The Hand secured a Human male for the Emperor to use as his newest Voice , and the Sith ruler took full possession of his host on the Imperial capital planet of Dromund Kaas . Now free to continue the preparations for the dark side ritual by which he would consume all life in the galaxy , the Emperor traveled to the Sith edifice known as the Dark Temple with an escort of Sith and members of the Imperial Guard . The Emperor then gathered his strength in the Temple ' s inner chambers , awaiting the moment that he could begin his ritual , but his plans were foiled when the Jedi Knight known as the Hero of Tython prevented the Emperor ' s servants from achieving the mass sacrifice that the Emperor required . From the fallen Jedi Tol Braga , the Hero learned the Emperor ' s location on Dromund Kaas , and the Knight decided to confront the Sith ruler while he was weakened . The Hero and a crew of allies infiltrated Dromund Kaas and the Dark Temple while a Republic invasion fleet attacked the Imperial capital , and the Emperor ' s Voice waited in the Dark Temple ' s inner chambers as the Knight and the astromech droid T7 - O1 fought through the Imperial Guardsmen and Sith defending the Emperor . The Emperor used his Human host to battle the Knight and T7 - O1 , summoning multiple phantom copies of the Voice with the Force to overwhelm his opponent . However , the battle ultimately saw the Jedi victorious , and a greatly weakened Emperor relinquished control of the dying Voice — who had been mortally wounded by the Knight ' s final lightsaber strike — in order to return to his true body . As a final act of vengeance , the Emperor used the Force to bring down the Dark Temple upon the Hero and T7 - O1 . Though the pair escaped the collapsing building , the Voice ' s body was crushed under tons of rubble . Personality and traits . The Human male had pale , wrinkled skin and red eyes , and he spoke with the Emperor ' s own emotionless voice while possessed by the Sith ruler . As the Voice of the Emperor , the Human ' s mind was completely subjugated by the Emperor ' s consciousness , and each of his actions were orchestrated by the Sith . Powers and abilities . As the Emperor ' s Voice , the Human wielded the Emperor ' s own immense strength in the Force and was capable of utilizing Force powers such as Force lightning and physical illusions .
