There is another weird thing. Warrod and Woldheim all look old. The council chairman,Hyperion,doesn't. Plus,he has those ears. He is most likely not human and he is probably ageless. The first one is Yuriy's spitting image,besides those antennae.
I am pretty sure he revealed him like this in order to set up a plot twist /revelation later on. Many people who dissed this arc probably will refrain themselves after this one.
Still,it sure would be sad to see that two of fairy tail's founding fathers strayed,and that only Warrod decided to inherit Mavis's will. Maybe Yuriy got an ageless curse cast on him,like Zeref and Mavis did. That would explain why his body didn't mature.
Plus,in a hundred years,it's possible to become the continent's strongest mage,lol. Only reason why Warrod is fourth is because not only he is old and because he doesn't know many offensive magics. Even in zero he observed that he was a back up mage. Hades,well... he sure was a monster,but old age caught up to him and without that heart,he couldn't use his full power.
