Starsabers were created by the Jedi Order, specifically the Jedi of Jedigan IV to be used as a planetary defense fleet, seven thousand years before the fall of the Old Republic to be used as an effective measure to defend planets and to defend Republic fleets. An incredibly rare version of the Starsaber had the ability to transform into a Jedi Battlesuit. It was an advancement made by Palpatine Skywalker who, at the time, was preparing to fight Darth Malice in his giant space form.
