The Panteer crown
Before the assassination of the final Panteer queen, Silara, and the subsequent dissolution of the Cold War, the Panteer crown functioned as the age-old, emblematic headwear of the Alderaan monarch.
When it went missing, the Queensguard, Sir Deris Panteer, who was nearing death, requested that visiting servants of the Sith Empire retrieve the crown from the ruins of Queen Silara's transport in the Glarus Valley. The Imperial servants discovered it relatively close to an escape pod, not far from the crash site, and then delivered it to Captain Lieber at the Panteer mountain sanctuary located within the valley.
