This may have been done before, but I haven't read through this huge thread, so bear with me. My idea for a Jacen redemption story (I would have preferred he not go Sith at all, but I digress), with a tie in to the first Legacy comic series (I haven't read the second series yet). I apologize in advance if I get a bit long winded. Anyway, here it is.. Instead of killing Jacen, Jaina somehow captures him. He's sent back to the GA to face charges and is sentenced to death, but Luke intercedes and instead he is exiled to some uninhabited planet to live out the rest of his days. Flash forward about 15 years. Allana is apprenticed to Jaina. Now this part would probably require some fudging of dates, because Allana would have to have been too young to remember what happened during LOTF. To protect her, her family makes up some story about how her father was killed during the war, but she doesn't know that Jacen is really her father. Meanwhile, Darth Krayt has gathered his forces and is preparing to invade the galaxy. Jaina and Allana are sent to some obscure world to investigate rumors of some ominous force gathering. They are attacked by the One Sith. Jaina escapes, but Allana is taken prisoner. Krayt, recognizing whose blood she has in her veins, decide to try to turn her to the Sith. Jaina returns to Coruscant and tells the GA about the existence of Krayt and the One Sith. She asks permission to rescue her apprentice, but is denied by the Jedi Council because they're more worried about the threat the One Sith pose.So she decides to go rogue (so unlike a Solo) and try to rescue Allana herself. But she knows she'll need help against the Sith, and decides what better help than a former Sith himself. Before she goes to find Jacen, she enlists the help of her parents. Han, Leia, and Jaina all leave on the Falcon (it's not really Star Wars without the Falcon). They go to the planet Jacen is exiled on, and find him a complete mess. He's spent the last 15 years beating himself up over what he's done. He hates himself, and in fact asks several times for them to kill him (very dark, I know). They tell him what's going on, give him emotional speeches about how he needs to get his act together, put the past in the past, and save his daughter. Eventually they get through to him and he agrees. As they're tracking down and planning a way to rescue Allana, Jacen is constantly battling his inner demons. Meanwhile Allana is battling a demon of her own in Krayt. Krayt uses his knowledge of her true father against her, telling her how he was a murderer and a Sith, and slowly she starts to slip towards the dark side as the anger builds up in her. Han, Leia, Jacen, and Jaina have found where Krayt and the One Sith are keeping Allana. Han and Leia use the Falcon as a diversion (along with some last second help from Luke, Ben, and the rest of the Jedi Order, who changed their minds) while Jacen and Jaina slip in to rescue Allana. Eventually they end up in some kind of throne room with Krayt and Allana, who is in the Embrace of Pain. The showdown starts, pitting Jacen and Jaina against Krayt. Eventually Jacen tells Jaina to free Allana and get out while he battles Krayt alone. Just as Jaina is getting her free, Jacen is struck down by a terrible blow. Seeing the man she now knows is her father struck down, Allana finds the strength to attack Krayt with Jaina. Eventually they defeat Krayt. Han and Leia, along with Luke and Ben, find their way to the throne room, to find Jacen, dying in his daughter's arms. He looks at Luke and Ben, and says he failed as a Jedi. He looks at his sister, and says he failed as a brother. He looks at his parents, and says he failed as a son. Finally he looks at Allana, and says he failed as a father. Then he tells them all that he loves them, closes his eyes, and fades away.
