Darth Atrius was a male Sith Lord who lived during the time the Sith were plentiful and powerful. He wielded two crossguard lightsabers. At some point after the Battle of Yavin, the smuggler Sana Starros recovered his pair of crossguard lightsabers. She took one to a crime lord on Hradreek whilst selling the other to the Galactic Empire. Both sabers were later destroyed by Luke Skywalker and Darth Vader.
