He was formerly the king of City of the New Dawn until Ahriman was released and attacked his city. He attempted to fight the new threat. However, not only did he lose but he was corrupted. As a result, he was also split into two people;himself and the Beast. He managed to, however, defeat his other half.
The Fallen King
After defeating the Beast, he had intended to imprison the Beast and fight off Ahriman. However, due to the intervention of the Prince, he was freed once again. This greatly angered the Magus but the Prince aids him in stopping the beast.
