My name is Kane Leumai, former Jedi Master, but now a former Sith Lord, also known as Darth Deimos. Trying to experiment with the Dark side of the Force can and will result in the creation of a Sith. I was an apprentice of Lord Sidious while Count Dooku was his current pawn, so technically I was a secret apprentice of sorts, breaking the Rule of Two and making way for irony given Lord Vader and Starkiller.
After Vader was.. indoctrinated, I was cast aside as weak compared to Vader, branding me as a threat to the Empire and using my former Jedi roots as a scapegoat, making me an official part of the Jedi Purge, now I am on the run with a formerly Imprisoned Miraluka Jedi. Hopefully my ship has enough power to make it to that small planet over there...

Takes place between Star Wars Episodes' III & IV and 6 months after MLP: FIM Season 4
