Well there needs to be a massive battle or another sort of event that would cause that much destruction on the 7th and I say demons would help add to that scale of destruction. One thing though forgot to say is that I'm guessing if Zeref did change Acnologia from what technically was a human into dragon, the destruction caused by the dragon made him feel an unbearable amount guilt leading him to learn the value of life and turning him into the depressing guy we saw in the Tenrou Arc. Anyway the interactivity of this blog is cool and R.I.P indeed.
