Before the Great War, Flagstaff was the first city in a series of carjackings committed by "Shanghai Sally" who was an alleged Chinese spy on the run from law enforcement. In 2255, the ruins of the city were taken over by Caesar's Legion, who christened it as their new capital.
Behind the scenes
Flagstaff is based on the real world location of Flagstaff, Arizona.
