8-second high-speed chase: A terrified wanderer sprints through dense mist as a colossal, mountain-sized stag-god thunders behind him. The beast smashes through ancient trees, antlers splintering massive branches. Ground-shaking heavy footfalls kick up dirt and debris. The beast's glowing green eyes leave neon streaks in the fog. High-speed shaky-cam tracking shot, epic scale dark fantasy, volumetric lighting, Unreal Engine 5 aesthetic.
