In China, the Dragon King is a deity who rules all of the water and protects its people. He is especially revered in coastal regions and is a god of good luck and prosperity. Many people pray to the dragon king to protect them from enemies and anger. The four major dragons are also featured in classic novels.
The Dragon King was originally a Hindu god, but over time he was adopted into the Buddhist pantheon. He rules the seas, and his worship spread with Buddhism from India to China and Korea. After Buddhism spread to Japan, the Dragon King was transformed into a Shinto god. He is believed to have originated from the same district, as the monk Hyeja. These two deities are considered representatives of the Shotoku Taishi (the 12 gods), who are the guardians of the universe.
Trials of the Dragon King introduces a number of new characters to the game. The Dragon King, who rules over all dragonkind, bestows titles to the brave and lends Jack his counsel. The Warriors of Light, who fight to restore light to the crystals and save the world, are also introduced. The game also introduces a new job chain and new weapons to Jack.
Another mythical dragon is the Dragon King of the North Sea, who turns into freezing wind and saves a monk from demons and a cooking fire. This myth is based on the story Ne Zha Churns the Sea, one of the more than one hundred tales from the Investiture of the Gods. It ends with Ne Zha killing the evil dragon, the son of the Dragon King of the East Sea.
