An old illustration style image with simple lineart, with clear colors and scraggly rough lines, historical colored lineart drawing of A serene underwater metropolis lies shrouded in mystery, with crumbling stone architecture overgrown by vibrant turquoise corals and wispy seaweed. Towering, monolithic pillars, half-buried in silt, support a grand, vaulted dome that now lies cracked and still. A lone, gleaming piano, abandoned on a worn, circular pedestal, stands as testament to a lost civilization, its soundboard reflecting the soft, blue-green hues of the surrounding waters. Schools of iridescent fish dart through the dimly lit, undulating landscape, as shafts of warm, golden light pierce the darkness, casting long shadows across the sea floor.
