Well, there goes Tartarus' scheme of destroying magic. So, the dragons were trying to prevent the dragonslayers to become just like how Acnologia became, huh? I hope there's more to explain why the dragons were hiding. Plus, I knew Acnologia won't go down too easily. Then, Gray is being a bit selfish that he's going to destroy E.N.D. himself. However, this is prevented thanks to a certain antagonist I like...Zeref! And once again, I will be listening to "Synchronicity" by Yui Makino for Zeref's reappearance.
