Constructed in the waning days of the Empire of Stars, the Chamber of Stars was a magical vault underneath Castle Ehb holding imperial weapons and armor. Foreseeing the collapse of the empire, the 10th Legion rounded up the strongest artifacts it could find and moved them to Ehb, there to be held in trust inside this vault. The King's gambit of trusting the chamber to Montbarron's discretion paid off; a former liability became a great asset as her team bore the Chamber's artifacts into battle against the Seck and their leader, Gom.
