Underwater view inside a massive, abandoned futuristic deep‑sea facility or submerged research station, looking upward through a large round reinforced glass dome hatch. Sunlight streams down from the surface in dramatic god rays, illuminating clear blue‑green ocean water filled with tiny bubbles and schools of small fish. The structure features industrial metal walls, rusted pipes, mechanical machinery, and corroded equipment. Sea life has reclaimed the space: coral, seaweed, and marine plants grow across the lower structures, with tropical fish, a shark gliding past, and a stingray swimming in the depths. Deep‑sea atmosphere, moody lighting, photorealistic, highly detailed, cinematic composition, 8K resolution, atmospheric depth, mysterious and serene tone.
