In the distant Lesser Blood Ocean that divided Sourna in half, a giant ship sailed, bearing a pirate's flag. Behind the skull on the flag was a red heart, a symbol that terrorized pirates worldwide. Aboard the ship's oaken decks, numerous men and women indulged in pleasure, heedless of time or place.
The reason behind such behavior was simple: these pirates served under Deluge, who allowed them to grow stronger through sexual intercourse. Beyond the pleasure, the benefits of indulging in this forbidden sin were akin to fighting monsters and absorbing their cores. This 'training method' was efficient enough to make his crew the strongest at sea, and their notorious behavior of raping their victims only added to the hatred they received. However, no one could touch them. They were the strongest.
