What are the first words the angel always says?
Dark Lord: Here's a little test for you, Mather, since you know your bible back-to-front. So tell me, whenever a human being encounters an angel in the books, what are the first words the angel always says?
Cotton: Be not afraid.
Dark Lord: Correct. And did you ever wonder why when encountering a human being an angel must immediately tell them not to be afraid? Because angels are monsters. We were then as are now: fearsome engines of wrath.
