David was a daring man. Ever since he was a child, he would do what others considered impossible. One, for the sake of proving himself to his parents.
And two, just to stand out from his peers. He was born a Gray, with a famous mother, and a powerful father. And even amongst the entire lineage of the Gray Family, they both stood out.

Yet in this New world of Gaia, the status of technology greatly decreased, hence those that focused on their mentality, were reduced in status.
