Three hundred years ago, a pirate captain named Crimson Moonlight sailed the seas, hunting and pillaging ships for their treasure. He was very rich, dangerous, and feared by any sailor. But, his most valuable asset was an ocean blue gem that granted the captain power over the sea, known as the Ocean's Soul

One day, fate caught up with the captain, causing him to fight until a blade to his chest ended his career of robbery and ruthlessness. However, when his ship was searched, not a single gold piece was found. And the Ocean's Soul was never recovered.
