it's pretty canon actually. Dragon Slayer magic is the only thing that's been shown to effect Dragons, which is why it was given to humans in the first place.

Considering Igneel, a dragon, was stated by Atlas to have been defeated by Zeref's demon E.N.D in the past, I truly doubt they are just immune to all magic and curses.

Aran/Nigel need a collab. I'm just saying.
