Darth Sion

Darth Sion, along with Darth Nihilus and Darth Traya, is one of the title characters in Star Wars Knights of the Old Republic II: The Sith Lords. His body consists of bits and pieces held together by sheer force of will and the power of hatred embodied by the dark side.

When the Sith Order on Korriban turned on themselves after Malak's death and Revan's dissappearance, Sion was apparently one of the Sith Lords that have escaped to the unknown regions in the galaxy. It seemed he had escaped to Malachor V, where he was apprenticed by Darth Traya, a former teacher of Darth Revan.

Darth Sion, along with fellow Sith Lord Darth Nihilus, was a former apprentice of Traya, before he and Nihilus cast her out of the Sith Order and stripped her of her powers. 3,951 years BBY, he was killed by the Exile who had served Darth Revan during the Mandalorian Wars in the Trayus Core, the heart of the Trayus Academy on the ancient Sith world of Malachor V.

Having lived so long knowing nothing but hatred, he was glad to leave that evil place at last.

Like most other Sith Lords whose names begin with Darth, Sion's name suggests another word: scion, meaning heir. In this case, heir to his master, Traya, and the legacy of the Sith.
