提示词
A massive black dragon bursts out of storm clouds above a medieval stone castle at night. Archers on the walls fire flaming arrows as the dragon unleashes a torrent of fire across the battlements. A lone knight in silver armor steps forward, raises her shield and shouts: "Hold the wall! Do not run!" The camera sweeps from a wide aerial view of the castle into a low close-up of the knight as flames roar past her shield. Epic fantasy war film, lightning, embers, dramatic orchestral score.
