Dragon king festival. Hey, did you all read the latest chapter? Clearly the dragon king festival has a lot to do with the dragon slayers, but what does the picture represent of the dragon fighting the mage? Some people say its a picture of the dragon king training a dragon slayer or fighting a dragon slayer. I believe it represents the dragons fighting Zeref
Here's my theory; The old man says its a festival of demons right? I believe that the demons correlate with the God Slayers, and Zeref, who terrorized the people and made themselves gods, with their demonic magic. It would also make sense with how Zeref knew Natsu, and how he wanted Natsu to kill him.
Remember how Natsu and Gajeel were assumed to be older than 80? I believe that whenever Zeref was active, so were they, and that they lost their memories fighting him or perhaps fighting alongside him. Somehow both the dragon slayers and Zeref lost their memories and aged backwards into child forms. And thats how the dragon slayers met their parents. Or maybe they were just children to begin with, and the Dragons had some unique magic to keep them young.
We know that there is a dragon king, so perhaps maybe he will make an appearance in this arc finally? Well I can't wait to find out, and tell me what you guys think!
I have no idea how the celestial spirit mages fit into this.
