  "prompt": "A dramatic, high-contrast digital painting suitable for a Clive Cussler novel cover. The central image is a deep-sea submersible, sleek and futuristic, emitting a powerful beam of light into the abyssal darkness. The beam illuminates ancient, ornate ruins partially submerged in the ocean floor, hinting at a lost civilization. In the distance, a school of bioluminescent fish casts an eerie glow. The overall mood is mysterious, adventurous, and slightly ominous. The color palette is dominated by deep blues, blacks, and teals, with contrasting highlights of electric blue from the submersible's light and the bioluminescence, and hints of gold or bronze within the ruins. The composition is dynamic, with the submersible positioned slightly off-center, drawing the eye into the scene. The atmosphere is one of vastness, pressure, and hidden danger. Square 1024x1024 format, professional audiobook cover aesthetic. NO text, NO letters, NO words, NO title, NO author name.",
