Humans are the most favored creations of God. So much so, that the four King blessed humanity with fragments of their power in the form of "The Gems". By only choosing a single human for wilding and using them to protect and guide humanity.
The last chosen died 1,500 years ago and now a new human was chosen, his name was Daniel Grayson. But, it was not done as a tradition but rather a necessity. A new threat was to come, as an end to humanity and everything else that existed.
But sadly for young Daniel, the prices to protect everything is quite...... high.
