#2 SLC : New Heroes 2 Of 2 : Galen Marek (Starkiller) [ Vaders Secret Apprentice ] Non Cannon

I would like to point out that the whole the force unleashed project was developped when lucas arts was run by george lucas himself and lucas was the main consultant while creating the story and the caracters so I think the story must be considered as cannonical as any other george lucas' creation
