An Ancient Sea Turtle Carries a Ruined City Beneath the Ocean

A breathtaking, high-concept celestial surrealist masterpiece of a colossal, ancient sea turtle swimming through the deep dark ocean. The turtle's giant, craggy shell carries a bustling, miniature ruined Atlantean city with glowing neon blue and purple lights and intricate temples. Translucent bioluminescent jellyfish drift gently around it under dark water. Shimmering sunlight rays and caustics cut through the depth. Deep emotional connection, majestic scale, sharp focus, 16k resolution, Unreal Engine 5 render.
