The Sullustan mirehound was a large canine animal that lived on the planet Sullust. It was a large, black animal that seemed to enjoy following travelers on the few roads that Sullust had. It was considered a doom to all travelers, as any and all who saw it, seemed to vanish without a trace. Nathaniel Kenobi was once told that his life seemed to have a Sullustan mirehound following it, as what it had been, was gone.
