An epic, hyper-dynamic apocalyptic cinematic video. The camera is positioned at ground level looking up in a steep angle toward a colossal Dark Angel standing at the edge of the horizon. He is wearing terrifying, sharp obsidian-black armor. At his feet, an entire world is in chaotic destruction, filled with raging fires and collapsing structures. At the start, his massive black feathered wings are tightly folded behind him. Then, a powerful, slow physical motion begins, he expands his wingspan wide, lifting and unfolding his tattered wings. As the wings spread open, they physically block out the sky like an eclipse. The camera tracks the sweeping movement of the feathers as his shadow gradually and realistically creeps across the landscape, swallowing the daylight second by second. The world plunges into total pitch-black darkness, until the daylight completely vanishes, leaving only the violent, hypnotic dancing of bright orange and crimson flames illuminating the heavy black smoke in the shadows. High-velocity embers flying, intense cinematic physical motion, photo-realistic, 8K resolution.
