The Graveyard of Super Star Destroyers was an asteroid belt near Alderaan. There, Adam Harmon had collected the remains of all battered Super Star Destroyers and began reconstructing them. In time, he had seven at the same time being worked on. As part of his reconstruction efforts, he also began cloning pilots and engineers and crew, to enable himself to more then adequately man these ships. It became a major point of conflict during the War of the Resurrected Emperor.
