Once a mighty Sith battleship, the Starworm now floats helplessly amongst the stars. Like many other wrecked starships from the Great Sith War, the Starworm was abandoned long ago by its owners. Since the war it has slowly been picked apart by salvagers.
The crew of the Aeon Harrier was given a commission to retrieve some components from the Starworm. Unfortunately this brought them into conflict with DeadStar Salvage and Sales. Apparently, the company had a (questionable) legal claim to salvage the Starworm.
