What Fate/Grand Order the Movie: Divine Realm of the Round Table: Camelot 1 Wandering; Agateram is
You wander the skeleton of Jerusalem in 1273, a knife-sharp mirage of sand where three warlords carve kingdoms from dust. Ahead, lost knights bearing the Round Table’s crest march toward the last besieged city. By the time you reach the Lion King’s gate, the world’s fuse has already been lit. Kei Suezawa frames Camelot’s fall as a desert epic shot through medieval war tapestry and anime muscle.
