The Panteer crown
Prior to the Cold War's commencement and the assassination of Silara, the last Panteer queen, the Panteer crown served as the traditional headwear for Alderaan's monarch.
A Queensguard named Sir Deris Panteer, as he was dying, requested that servants of the Sith Empire who were visiting, retrieve the lost crown from the wreckage of Queen Silara's transport, which was located in the Glarus Valley. The Imperial servants found the crown close to an escape pod, not far from the crash site, and took it to Captain Lieber at the Panteer mountain refuge in the valley.
