This is the Main Rebel Camp's "Castle". It only moves once a year, unlike all the other Rebel Camps which are set up through out the other main Kingdoms which move all the time (usually once a month more often if compromised). This is home to the Empress herself, and the "castle" isn't much of a castle. It's more of a large Victorian-like tent created with the use a special rune. It is the place where all the planning for raids take place. It has been sound proofed by an inscriber.
