one theory about how the dragon slayers is their age. because of the dragons were inside them which igneel already revealed to natsu that he was inside him the entire time make sense why they couldnt go through the runes. and also in the manga they felt pain when tyhe dragons were coming back.

just a theory feel free to correct it
