Behind the scenes

 * The title of this challenge is a reference to a quote made by Richter Belmont in Castlevania: Symphony of the Night, when confronting Dracula ("Die, Monster! You don't belong in this world!").  Another Gun Runners' Arsenal challenge, The Same Could Be Said of All Religious Weapons, references this conversation as well.
