One of the major external problems in the story is that Carnival, an angel, is killing the people of Deep Gate. The only reason that she is doing this is because she needs to consume a soul once a month to stay alive. The priest of Deep Gate has had one of his chemists to create this potion called Angel Wine, this will make the angel immortal and will no longer need to consume the souls of Deep Gate. The internal conflict that the priest is having about his plan is that he doesn't know if Carnival will stop killing the people even though she doesn't need to. He is consulting his advisors about the problem but some of them aren't taking it very well and threaten to tell the rest of the city about his dangerous plan.
