A cavernous abyss beneath the ocean floor. Bioluminescent creatures cast an eerie glow on jagged rock formations. Ghostly shipwrecks litter the seafloor, their treasures long lost. Bubbles rise from hidden fissures. A monstrous kraken lurks in the shadows. Its massive tentacles, covered in ancient scars, coil around forgotten ruins. Enormous eyes gleam with predatory intelligence. Rows of razor-sharp teeth line its beak. Its leathery skin shifts colors to match its surroundings. A crown of barnacles adorns its head. Haunting whale songs echo in the distance. Currents swirl ominously around its lair.
