垂直俯冲：兽人堡垒攻城战

[0–5s]: Vertical descent from sky
Ultra-high altitude above a sunny, orc coastal fortress at stormy dusk, the wooden stronghold centered in frame, surrounded by icy cliffs, longships, and smoke. The camera begins in dark clouds and plummets straight down at immense speed, cutting through the cleark sky. Strong motion blur, violent wind effects, subtle lens distortion, and chaotic shake emphasize the descent. Fires, siege ladders, and shield walls become visible as the fortress fills the frame.
[5–10s]: Stabilization into siege FPV
Just before impact, the motion snaps into a smooth FPV glide through the fortress breach. A full orc siege is underway. Axes crash into shields, arrows streak overhead, berserkers scream, and burning debris falls from above. The camera flies low through mud, bodies, shattered wood, and charging warriors, dodging swinging axes and collapsing barricades. Snow, smoke, sparks, and embers swirl through the air.
[10–15s]: Wolf cage pass + whip pan to orc chieftain
The camera cuts tightly past a heavy iron cage holding snarling wolves, one slamming against the bars with teeth bared. Then a fast whip pan lands on the orc chieftain standing atop the battlements, fur cloak billowing, roaring orders onto the battlefield.
