15-second cinematic sci-fi action sequence, 16:9, ultra-realistic, IMAX-quality cinematography, breathtaking scale, realistic motion, no visible face, no text, no dialogue. A lone spacecraft flies through a dense field of orbital habitats illuminated by a brilliant sun. Everything is bright. Then darkness begins moving across the structures. Not an eclipse. A shadow. The shadow sweeps across stations, ships and habitats at incredible speed. Every vehicle touched by the darkness instantly loses power and drifts lifelessly. The pilot realizes the shadow is chasing him. Entire stations go dark behind the spacecraft. Navigation lights disappear. Cities vanish into blackness. The shadow closes the distance. Closer. Closer. Ahead, a narrow corridor of sunlight remains between two rotating habitats. The pilot commits. The corridor collapses into darkness immediately after the spacecraft passes through. Cut.
