Hehehehehe. Ahahahahaha. MUAHAHAHAHAHAHA!! -continues for eternity-

EHEM! Well, I was right, and I was right all along. Dragons were a very common sight 400 years ago. They were rulers of the world. I actually saw this coming a mile away. ALL OF YOU SUCK! Sorry, sorry. But in all seriousness. This is the development I was personally waiting for, so now that Buchanan and his Lunar Dragon Slayer Magic can go on ahead as I planned it. This will be so much fun though...hehehe :3

Even more, this was kind of foreshadowed with all the Dragons Graves and DRAGON FORCE. That thing makes you have scales guys, scales. So, my theory about Dragon Slayers in general was right all along.

Now while I bask in my psychic glory, I'd also like to add something else.

I doubt Acnologia is actually "royalty" among Dragons. If that were the case, it'd be extremely unusual for him to simply be out in the open, especially with the likes of Zeref. He obtained his title through sheer power, and this power forced him to undergo this transformation into the most powerful dragon known. So, he isn't royalty, he's simply someone with alot of magical and physical power who was named the "King" cause nobody could beat him up :3
