Blue Sun was the name of a corporation that operated in the galaxy some time after the Galactic Civil War. A production company the organization produced everything from ship parts to food stuffs. The origins of the company are shrouded in mystery as it seemed to have cropped up into public eye from nowhere but evidence of its existence, namely the Firefly-class put it being in operation at least by the end of the clone wars.
Sometime following the Second Civil War the company began working with some underground and fringe elements towards creating artificial force users. By 100 ABY several of the facilities dedicated to this project came under attack from several elements, though Blue Sun managed to come out relatively unscaved.
