Lieber, a male Human captain, served within the Queensguard of House Panteer. He was active during the Cold War era, a period of tension between the Galactic Republic and the newly reformed Sith Empire.
Lieber's assignment in 3643 BBY placed him at the Panteer hideout located on Alderaan. At this location, an Imperial spacer found the Panteer crown in a river close by and handed it over to him.
