Exal Kressh Exal Kressh was a Sith female who was apprenticed to the Sith Emperor of the resurgent Sith Empire during the early years of the Great Galactic War . A descendant of the Sith Lord Ludo Kressh , Exal betrayed her Master when she learned of his plan to create " Children " who were connected to his will . She gave intelligence on Imperial fleet movements to the forces of the Galactic Republic , so they could plan an attack on the planet Korriban . When she was confronted by Sith apprentice Teneb Kel on a space station near the planet Lenico IV , Kressh sabotaged the station and escaped , resulting in the colony ' s destruction . Kressh made her way to Korriban so she could raze the Sith Academy and halt the Sith Emperor ' s project during the Republic ' s assault on the planet . However , she was defeated by Kel at the Academy . Biography . Exal Kressh was selected to be the Sith Emperor ' s apprentice , a role in which she served until the early years of the Great Galactic War , when she discovered he intended to hollow her mind out and fill it with his own , making her the first of his " Children . " In response , Exal abandoned her duties in the Kathol Rift and fled toward the fringes of Republic Space , and possibly sending information to the Republic . The Emperor and the Dark Council responded by assigning the Sith apprentice Teneb Kel to hunt her down and kill her . Kressh destroyed Lenico Colony Blue while fighting against Teneb . Teneb barely survived the duel , but was able to escape from the colony and continue his mission to find her . Kressh attempted to destroy the Emperor ' s project to make his children by assisting the Republic on an assault on Korriban . Secretly helping the Republic , she intended to sabotage the planet ' s defenses to allow the Republic to infiltrate the planet . She was met again by Teneb Kel , though she once again held the upper hand against him in combat . However , when Teneb ' s warrior slave Maggot intervened , Teneb took his chance by killing Kressh , therefore preventing her from sabotaging the planet ' s defenses or destroying the Emperor ' s project . She finally came to the point that her arrogance and superiority undermined her when Teneb used the Force to bring a fallen Sith ' s lightsaber to stab her from behind . Before dying , she heard the Emperor ' s voice in her head one last time , giving words of mockery , " You are nothing " , the voice said , then she fell to the floor . Personality and traits . As the Emperor ' s apprentice , Exal Kressh at first believed she was special when the Emperor took her under his tutelage . This fact gave her a severe superiority complex , which she expressed during her duels with Teneb Kel . Kressh was supremely proud of her Sith heritage . She believed it was her right and privilege by blood to become the Emperor ' s apprentice and heir . However , after the Emperor attempted to make her his slave instead of his heir , she felt betrayed by her Master . Her hatred towards the Emperor was such that she was willing to give vital Imperial information to the Jedi and the Republic that would potentially undermine the Empire ' s campaign in the Great Galactic War . Still , even though she left the Emperor ' s side , Kressh was constantly tormented by the persistent taunts and commands he projected into her mind , which was gradually driving her mad . However , even though she resisted the Emperor ' s presence in her consciousness , she felt invincible just because the Emperor hollowed her out and filled her with his strength , believing she could defeat any agents the Dark Council sent after her . Unfortunately , it was her arrogance and superiority complex that caused her to underestimate her enemies , which lead to her death at the hands of Teneb Kel . Powers and abilities . Exal Kressh was a member of the Kressh bloodline , strong in the Force , and was trained in the ways of the dark side by Vitiate . She was remarkably skilled in martial aspects of combat as she was able to kill numerous Sith on Korriban and outmaneuver Teneb Kel . Her attacking strategies involved leaping at the opponents with ferocious two - handed strikes and attacking their flanks with one - handed thrusts . Kressh was proficient in the use of Force lightning , using it to obliterate Teneb Kel ' s lightsaber and incapacitating Qawohl . She was also proficient in the use of the protection bubble , utilizing this talent to defend herself from countless shards of crystalline permaglass thrown at her by Teneb Kel . Furthermore , she was proficient in the use of telekinesis , using these powers to overwhelm multiple opponents , destroy the space station known as Lenico Colony Blue , disintegrate a large stone column of the Sith Academy on Korriban , and immobilize Teneb Kel . Kressh shared a powerful bond with Vitiate , evidenced by the frequent telepathic taunts and commands he sent into her mind . Kressh also appeared to have an extremely high tolerance to physical pain ; this was demonstrated when Qawohl shot her twice and she was still battle - capable .
