An underwater city with ancient ruins and modern architecture intertwined, lush, colorful coral reefs surrounding the city, schools of vibrant fish swimming through the buildings, a serene, tranquil atmosphere with soft, ethereal lighting filtering through the water, bright sunlight streaming from the surface, creating shimmering patterns, gentle illumination from bioluminescent organisms. Wide-angle shot to capture the expanse of the underwater city, slightly tilted angle to give a sense of depth and immersion, lens flare, fractal patterns, link flare, luminogram effects, multiple exposure, Christian Lassen, ghost ship, shipwreck, ancient ruins, building. Crystal clear water, enhanced transparency, and a dreamy, ethereal glow.
