“A man lies in a darkened cell, consumed by pain and sickness. He does not know where he is. He does not know how he came to be there. He does not even know his own name. All he knows is that he is being tortured by a bizarre, bespectacled man, who addresses him only as a number - Twelve-Thirteen.” - Ben 'Yahtzee' Croshaw
