Aged Submarine Lies Abandoned on the Rugged Ocean Floor

An aged submarine lies abandoned on the rugged ocean floor, its formidable, once-dark exterior now marked by rust and draped in barnacles. The tilted conning tower adds to its decrepit state, while glowing jellyfish drift gracefully through its broken windows. Surrounding waters shimmer in a muted emerald hue, with weak rays of light filtering through the depths and casting haunting shadows across the submarine's deteriorated frame.
