Enchanting Underwater Fantasy Keychain

An enchanting underwater fantasy scene bathed in shades of purple, evoking a sense of mystery and wonder. Towering coral structures in vibrant hues of lavender and amethyst stretch towards the surface, glowing softly with bioluminescent light. Ethereal jellyfish drift gracefully, their translucent bodies radiating gentle purple and blue hues. Schools of exotic fish, shimmering with metallic tones, weave through the coral, creating a mesmerizing display of movement. In the background, a sunken ancient city lies partially hidden by marine plants, its ruins glowing faintly with magical light. Shafts of dim light filter through the water, casting an otherworldly glow over the dreamlike underwater realm.
