Long ago, the Transmutation Guardian mastered the elements. He learned how to create and change them from one to the other. This was an era of prosperity until a jealous brother changed that. The one who rendered the Origin Pillars helpless was none other than the God of Destruction.
The Transmutation Guardian declared his plans for a new world where his people could live in peace away from the struggle. What happened after was hard to say, but Arthur was sure that the God of Destruction was responsible. He made it seem that the Transmutation Guardian was the one behind the Origin Pillars losing their elements, but Arthur believed otherwise.
If a person managed to convert elements into strength, they would be the prime suspect behind the stolen elements. After that, the guardian made the people believe he was their protector against the thief, earning the name of the Protector Guardian.
