Sora提示词：Cinematic 21:9 dark fantasy scene on fortress walls.

Cinematic 21:9 dark fantasy scene on fortress walls.
An older ape general with a weathered face gives a slow thumbs-down signal.
Then massive ground-mounted crossbows unleash volleys of black iron bolts toward charging one-horned dragons on the slope below.
Arrows punch through dragon bodies, riders fall, blood and dust explode in the cold blue morning light, three pale moons still faint in the sky.
Cool blue palette with sharp white highlights, highly detailed, no text.
