Biography
Castle is an exceedingly wealthy and expertly skilled computer programmer who has discovered the use of self-replicating nanites in the year 2024. These nanites mimic brain cells and can be used by a person to control another person's bahaviour and actions, much like a video game character. Castle had gained his monstrous fortune by creating two real-life video games: the first, called Society, is a game where the player controls a real person in a pseudo society and makes them perform various actions (anything from verbal interactions to making love with a total stranger). The second, called Slayers, is a real-life first-person shooter game where players control death row or life imprisoned inmates, and if the inmates survive thirty rounds, they are granted their freedom.
