The lost city of Atlantis submerged underwater, with ancient glowing ruins, intricately detailed temples covered in vibrant coral and anemones, epic mystical lighting that casts an ethereal glow, cinematic composition, ultra-realistic depiction of the submerged cityscape, with schools of exotic fish swimming through the structure, and a vast array of marine life thriving among the architecture, set against a dark blue backdrop with hints of turquoise and purple hues that evoke a sense of mystery and wonder.
