Behind the scenes

 * The title of this challenge is a reference to a quote made by Dracula in Castlevania: Symphony of the Night. When accused by Richter Belmont of "stealing men's souls and making them his slaves", Dracula responds by saying, "perhaps the same could be said of all religions." Another Gun Runners' Arsenal challenge, You Don't Belong In This World!, references this conversation as well.
