Sirius Venn, sometimes jokingly called Deadeye Duncan by those who knew him, was a Jedi Master during the Great Territorial War. Along with Kain Lightbringer, he was instrumental in the rebuilding process on Ossus after discovering the location to the lost planet in an ancient holocron. He helped operate the Republic shipyards around Ossus during the restoration process, and he sometimes jokingly referred to the shipyards as the S.S. Ships Ahoy. After the war, he opened a bar in Theed on Utapau called Bar Bar Drinks.
