Oceanic Ruins Under Celestial Light

An underwater realm where bioluminescent creatures illuminate the ocean depths. Coral structures resembling ancient ruins rise from the seabed, covered in glowing algae. A mermaid with shimmering scales swims gracefully among the ruins, her eyes reflecting the light of a distant supernova visible through the water's surface. The scene captures the beauty and mystery of the ocean, intertwined with celestial elements.
