The Duel on Alderaan was a lightsaber duel that took place between Jedi Master Ussej Padric Bac and Darth Viea, the Dark Lady of the Sith, on Alderaan fifteen to twenty years after the Great Territorial War. The galaxy-at-large believed that Bac killed Viea, though they both disappeared after the conflict. There were rumors that Viea was still alive following the conflict, and Bac began a quest to find a number of artifacts that would lead him to discovering the knowledge of the Bendu Order.
