A majestic sea dragon rising up from the depths, its scales glinting like diamonds, as a school of angelfish swirl around its head, and a sunken ship in the background, covered in coral and anemones, at the cost of the sea's ancient mysteries.

A regal sea turtle gliding effortlessly through the crystal-clear waters, its shell glistening with a subtle iridescence, as a school of smaller fish dart around it, and a faint outline of a treasure map etched on the sandy seafloor at the cost of the sea's secrets.

A majestic mermaid emerging from the depths of the ocean, her shimmering scales catching the sunlight that filters through the waves, surrounded by a school of sparkling fish and a treasure chest overflowing with glittering jewels and coins at the cost of the sea.
