Darth Traiton



"Maybe, maybe the Dark Side isn't what's best. Maybe the Jedi are better."

- Traiton just before leaving the Sith

Darth Traiton was the final Sith Lord in the Order of Corruption. He eventually lived up to his namesake and became a Jedi before taking a Sith apprentice. Thus, the Order of Corruption ended with his betrayal.
