User blog comment:Sargenttacos115/Natsu and Gajeel age Theory/@comment-108.129.33.178-20140715134145

This is a good theory and all, but here's mine. First of all, in the battle of Fairy Tail, Natsu and Gajeel couldn't pass through it because it said specifically, you can't be 80 or older. Since Dragon Slayer magic is lost and ancient magic, Natsu and Gajeel couldn't pass through because they are real dragon slayers. Now, if wendy were there, she wouldn't be able to pass through also. Also, if you pay attention to the flashbacks, Natsu and Gray look about the same age. But if Erza and Mira look older then Gray and Natsu, My best guess is that Erza and Mira are both nineteen, Gray is eighteen, and Natsu is probably in his older teens, my best guess is eighteen, leaving Lucy to be seventeen. This is just my theory.
