Arktisk vargkamp under norrskenet

**Environment:** A frozen tundra under aurora-lit night skies. Pale green northern lights reflecting across a wide snowfield with icy winds sweeping snow particles across the ground. **Action:** 15.0s sequence. A giant silver arctic wolf charges across the snow while a rival black wolf emerges from the drifting snowstorm. The two wolves collide in a powerful clash, sliding across the icy surface. Velocity Ramp choreography: the moment their bodies collide freezes briefly as snow explodes around them before snapping back to full speed as they tumble across the frozen ground. **Camera:** Low tracking shot racing through blowing snow alongside the wolves, occasionally capturing the action reflected across icy surfaces. **Style & Constraints:** Photorealistic fur simulation, volumetric snow particles, aurora sky lighting, cinematic cold atmosphere, 35mm film grain, 8K.
