"Oh, this faithless world! Someone must deliver them. You. If not you, who? You have been saved for a reason. Show them the old demons. Remind them of their fear. Apathy is death. Without darkness, there is no light. Without evil, there is no good. Make them choose. Dark or light. Where is the fear? Where are the heroes? If not now, when?"
