Castle Extremis

Castle Extremis was an advance post in the war between Anthium and Zerugma. A peace treaty was to be signed there to end the war, but it was interrupted when General Orlo announced his mutiny.

It was also the home of the Mortal Monks and where The Mortal Mirror was created in memory of them.

After the peace treaties were signed, the Galactic Alliance were going to turn the place into a historical park where tourists could see where the war was held. (NSA, Martha in the Mirror)
