In the heart of the Dark Ocean, where waters are black as the deepest night, reside the mythical Black Dolphins, guardians of ancient sea secrets. These creatures, shrouded in legend, appear only on moonless nights, their silvery skins reflecting the starlit water as they glide silently. They possess the magical ability to transform ordinary sea stones into precious pearls, each holding a fragment of ancient wisdom. This wisdom is accessible only to those who truly respect the sea and its inhabitants, making every encounter with a Black Dolphin a potential source of deep knowledge and luck.
