PROMPT:
A fantastical underwater kingdom hidden inside a glowing iridescent shell, illuminated by soft luminescent orbs, surrounded by a kaleidoscope of marine life, vibrant coral reefs, and sunken treasures, with a wise and powerful octopus monarch sitting on a throne made of shimmering mother-of-pearl, wearing a radiant crown adorned with glittering gemstones, as schools of bioluminescent fish dance and swim around it, set against a gradient blue background that transitions from deep indigo to turquoise, with bursts of bright yellow, orange, and green hues, creating a mesmerizing and whimsical atmosphere, rendered in a highly detailed and photorealistic comic book style, with bold lines, intricate textures, and a mix of realistic and stylized elements.
