Un cavall mític entra en un llac boirós

Create a 31-second ultra-realistic cinematic fantasy video in vertical 9:16 format, filmed from a first-person POV perspective.

**Scene 1 (0–10 seconds):** A rider is riding a powerful dark mythical horse with long pointed ears and a flowing black mane across a vast green rocky landscape. The camera captures the horse's head, ears, and saddle from the rider's perspective. Overcast sky, realistic wind and natural movement.

**Scene 2 (10–20 seconds):** The horse slowly approaches a huge mysterious lake and walks directly into the deep water. The camera follows naturally as water splashes around the horse. A foggy horizon creates a mysterious cinematic atmosphere.

**Scene 3 (20–27 seconds):** The camera gradually moves beneath the water, revealing a beautiful deep blue underwater world. Sunlight rays penetrate the water, creating magical cinematic lighting.

**Scene 4 (27–31 seconds):** The camera rises dramatically toward the water's surface, revealing the dark mythical horse against the cloudy sky.

**VISUAL STYLE:** Photorealistic, cinematic fantasy, immersive first-person POV, realistic horse movement, detailed water physics, atmospheric fog, natural lighting, smooth camera motion, 4K quality, no text, no logos, no watermark.
