" People need devils and dark gods, if only to give them a foe to rally against, an obstacle to overcome. Your people understood that there can be no light without darkness, no good without evil, no triumph without setbacks. You can't kill me because I'm part of all that you are, all you've done and plan to do. You don't have to like me. You can even loathe me. But you must accept me. "

― Darren Shan , Hell's Heroes (The Demonata, #10)
