E.N.D ETHORIOUS NATSU DRAGNEEL a demon from the book of Zeref, him and Wendy, Sting, Rouge, Gajeel, all the dragon slayers who were taught দ্বারা ড্রাগন are আরো than 400 years old, the Heartfilia's have been guarding the Eclispe gate for a long time and the time when Layla used it she brought the dragonslayers through, that is the reason why they couldn't go through the enchantment "you have to be 80 years অথবা younger to pass through the enchantment."
