Mason was a quiet, hardworking boy who had a real passion for physics from an early age. His father was a gifted engineer and his mother doted on him, raising him in a makeshift bunker underground that his father had built. He suffered a tragedy when his father died in the early moments of the Mayday Omega disaster.

Mason's mother became increasingly convinced her son was special as he demonstrated immunity to Starfall. Eventually, Mason came to believe in his own specialness too. When he heard about the Hunters, he knew he had found his destiny.

Mason's only purpose in life from that moment forth was to become a Hunter. He didn't pay attention to the human lives lost in the process of him assembling his own shell. His purpose was clear to him—he was the chosen one, and all the lost lives were merely the price that had to be paid to redeem humanity's sins.

Mason traveled the world and created his own Holy Book, replete with his own commandments. He has attracted a growing following of people who regard him as a new messiah.
