Prompt: Etherial Underwater Metropolis: Submerged in an otherworldly luminescence, a city of coral and crystalline structures stretches across the ocean floor. Bioluminescent flora bathes the underwater metropolis in an ethereal glow, casting intricate shadows on the iridescent sea creatures that navigate the maze of spires. The scene, reminiscent of H.R. Giger's surrealism, is a blend of alien beauty and the mysterious depths of the ocean.
