Darth Sion

"Yes...of pain he has learned much. Of knowledge, of teaching, he knows nothing."

- Kreia

Darth Sion (&mdash;3,951 BBY) was a Sith Lord around 4,000 BBY. Sion was unique in that he would normally be dead if not for the power of hatred embodied by the dark side and sheer force of will that held together his body, damaged to the point it consisted of burned bits and pieces. He was in constant pain.

Biography
When the factions of the Sith Order on Korriban turned on each other after Malak's death and Revan's disappearance, Sion was one of the Sith Lords that escaped to the Unknown Regions of the galaxy. It seemed he had escaped to Malachor V, where he was apprenticed by Darth Traya, a former teacher of Darth Revan.

Sion was a uniquely powerful Sith Lord, having learned the ways of pain in the Trayus Academy on Malachor V. Torturing and killing others help him enhance his strength in the Force, and his ability to feed on his own pain and hatred made him immortal. Sion was master with a lightsaber and arguably the most infamous and deadly Sith Assassin of the era, Sion was known to be responsible for the deaths of countless Jedi during the shadow war waged by himself and Darth Nihilus.

While on Korriban, he captured and killed Jedi Master Lonna Vash, who was one of the members of the Jedi Council which sent the Jedi Exile to the Outer Rim as part of his exile. He would later duel with the Exile on Korriban, and defeat him, but the Exile was able to escape Vash's fate.

Darth Sion, along with fellow Sith, Darth Nihilus, was a former apprentice of Darth Traya, before he and Nihilus cast her out of the Sith Order and stripped her of her powers. 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. He is listed here for the reason that he was a Dark Lord of the Sith, under Darth Nihilus, but he died before he actually succeeded to the mantle. He did not have the status of an apprentice, nor that of a complete equal, he was fully trained, but wasn't strong enough to take complete control from Nihilus, nor did he intend to, all that mattered to Sion, was the total death of the Jedi Knights.

Having lived so long knowing nothing but hatred, he was glad to leave that evil place at last. Interestingly enough, because of Sion's command of his own pain, saber skills, and preternatural ability to survive through the dark side, the Exile was unable to defeat him in hand to hand combat. Instead, the Exile was forced to use his powers of persuasion to turn Sion against his own beliefs, he eroded his will and convinced him that Darth Traya had no more use for him, and that by giving up the Force, he would finally be free from the horrible pain and hatred which he endured. Sion gave in to the Exile's influence, sacrificing his own life to the Force. His last words were:
 * "I am glad to leave this place at last."

Powers and abilities
Sion was a master of the dark side and certainly knew how to inflict pain and torment on those unlucky enough to face him. He was an exceptionally skilled lightsaber duelist and had learned to channel his pain through the dark side, making him literally immortal.He also used an advanced version of drain life called death field in the game. Sion was said to have mastered a unique style of lightsaber combat by combining aspects of Makashi, Dun Möch, and Djem So; he used all of these skills with peak deadliness, making him a brutal and vicious adversary.

Unlike most of the Sith of the time and, for that matter, throughout history, Darth Sion cared nothing for ruling an empire or conquering the universe; his only concern was the total and utter destruction of the Jedi Order. This was a task which he saw to personally with unimaginable success. Sion was considered by most to be a volatile brute. He cared nothing for teaching and knowledge - all that fueled his ambitions were his terrible pain, rage, and commitment to see the Jedi Order extinct.

The Lord of Pain despised weakness and had a respect only for raw and brutal power. He seemed to hold great contempt and disgust for the former Sith Lord, Darth Revan, preferring Malak's leadership as he stated so at one point to the Exile:
 * "Malak had strength, and embraced it, saw his opportunity and took it. The Lord Revan had the chance to rule over an empire, to heal this broken galaxy and make it strong, instead he chose to surrender it to weakness, and he ran away."

Behind the scenes
*Darth Sion was voiced by Louis Mellis.
 * 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.
 * Sion, like many other characters in Star Wars: Knights of the Old Republic II: The Sith Lords, was supposed to have a few more scenes such as a confrontation between him and Nihilus and a duel against Atton Rand, Sion would defeat Atton by cutting off his hand. Sion would then proceed to torture Atton, and make him experience true pain, before he killed him, unless the player controlling Atton can defeat Sion and from there, Atton would escape and leave Malachor with the Exile.
 * Sion's view of The Exile is different depending on the Exile's gender. If the Exile is male, Sion absolutly despises him and believes that he is weak, mainly because Kreia respects the Exile more.  He wishes nothing more than to kill him because of that.  If the Exile is a female, Sion seems to develop feelings for her, saying that she and Kreia are alike only more beautiful.  He warned her about Kreia's teachings and even hold off some of his assassins that were trying to kill her.
