- "Master. I have exciting news! A trail of corpses—all slain the same way as the light side Sith I found—has led me to the perpetrator. His name is Lord Cendence. He's been secretly hand chosen by the Dark Council to eradicate any and all Sith who are not pure."
- ―Jaesa Willsaam
There were some adherents of the Sith teachings that, for whatever reason, rejected the dark side of the Force in favor of the light. Nonetheless, these Sith retained their devotion to the Sith as an organization and were called Light Sith or light-sided Sith.
During the Cold War a group of light-leaning Sith formed within the ranks of the Sith Empire. The Dark Lord Cendence was hand chosen by the Dark Council to hunt down and destroy any Sith not deemed "pure".
- "I'm becoming aware of false Sith! Lords who are secretly leaning towards the Light!"
- ―Jaesa Willsam
During this time, Sith apprentice Jaesa Willsaam was ordered by her Master to track down the renegade Sith. Jaesa succeeded in her mission and slaughtered them all. A while later, she found a gravely injured Light Sith. Before he died, he told about Cendence. Jaesa found Cendence, but after realizing that he killed any Sith he pleased, she killed him. Caliqu, another Sith Lord, then gave Jaesa his position.
- "The last Sith possessed of the knowledge had been inexplicably drawn to the light side, and killed, taking the secret process with him."
- ―Darth Plagueis
Centuries later a Sith Lord named Darth Gravid also came to the conclusion that pure devotion to the dark side would curse the Sith of his era to the same fate as their predecessors, and sought a new philosophy in which the Sith would follow the light side of the Force, strengthening themselves with compassion and love, as their Jedi counterparts did. Sealed away in his Jaguada bastion Gravid set about amassing centuries worth of Sith lore that had been passed down from Master to apprentice since the time of Darth Bane, including: holocrons, crystals, scrolls, tomes, amulets and all other manner of artifacts, and proceeded to burn them, seeking to ensure that future generations of aspiring Sith remained committed to the path he had laid before them.
Unfortunately, Gravid's apprentice Darth Gean did not share her Master's vision. Horrified by the destruction of the Sith's treasures she threw herself at her Master, attacking Gravid with her bare hands, and after a violent struggle, succeeded in killing him, bringing an abrupt end to his plans. Although many valuable artifacts and teachings were consigned to the flames, including the coveted technique of essence transfer, Gean did manage to preserve enough material with which to instruct her own apprentice, ensuring the continuation of Darth Bane's original intentions: Unfaltering allegiance to the dark side.
Darth Plagueis later recounted the events of Darth Gravid's demise in regards to seeking out the lost method of immortality. Likewise, Plagueis would do something similar in spirit to Gravid—he attempted to end the Rule of Two, only to end up being murdered by his apprentice, Darth Sidious as a consequence, who felt that ending it was against the nature of the dark side.
Behind the scenesEdit
Should Jaesa Williams remain on the light side, she instead seeks out the Light Sith in hopes of alliance. Her first attempts are unsuccessful as they are suspicious of her and attack, forcing Williams to kill in self defense. Surviving as a Light Sith requires a healthy level of suspicion, as her master is well aware, and her approach was too naive to be believable. Future attempts work much better.
It is possible for a player Sith Warrior or Sith Inquisitor to be a Light Sith. In the inquisitor's case, their approach leads them to earn the title of Darth Imperius, due to playing their light actions as pragmatism that helps the Empire in the long run.
Originally, in Star Wars: The Old Republic all light side Sith the player encounters throughout the game wielded purple-bladed lightsabers. This was due to a gameplay mechanic which allowed the use of red colored crystals to darksiders only. This limitation has since been removed, however.
