For over a thousand generations the Jedi had been the guardians of peace and justice in the old republic, before the Dark times, before the Empire. The Clone wars had been a lie. A distraction meant to focus the galaxies attention away from the fact that the Sith now ruled the galaxy.
The plan had been to let the boy Luke grow up with his adopted Aunt and uncle, unfortunately that was not to be as an old enemy had paid the Lars moisturizer farm a visit. Maul had come looking for him to revenge himself on the wounds Kenobi had given him. While Obi wan had arrived in time to save the boy his aunt and uncle had been cut down by the sith assassin. With no one else to look after him Kenobi took Luke on as his apprentice and began training him in the ways of the force. One day the pair would encounter a jawa sandcrawler and come upon a golden protocol droid named C3PO and his counterpart R2-D2 who happened to be in search of the old man carrying a message from a princess seeking aid. It was time for Kenobi and Luke to venture into the galaxy once more.
From here things would progess much as they did in a new hope with Kenobi facing Vader and sacrificing himself and Luke destroying the Death Star. From their however things will take a turn as the Emperor figuring out the young man's identity sends his hand Mara Jade to attempt to bring Luke before him.
From here I am thinking that we can tell a whole new story with Luke confronting not only Vader but the Emperor's hand Mara Jade. With you playing Mara and me playing Luke. I am thinking that the 2 will start as advesaries, but will eventually become allies and more over time.
