Aurora Over the Industrial Gear Factory

Photorealistic interior of a vast gear factory at night. An aurora borealis arcs through cracked skylights, its green, teal, and violet ribbons washing over rows of heavy machinery, grinding benches, and giant gears. Realistic reflections on oil-slicked concrete and polished steel, dust motes illuminated by ambient factory lighting. Sparks from a distant welder, steam swirling in cold air. Foreground: a massive gear on a lathe; midground: assembly lines and racks; background: aurora-lit skylights. Hyper-detailed textures, HDR lighting, cinematic composition, 8k realism, shallow depth of field with foreground gear in focus and background aurora softly blurred.
