Nice chapter, finally some background on the dragons, Lucy <33
dat dragon character was awesome, along with finding out he was actually on the opposite side and rejected humans. It would be interesting to think a bit about Natsu being the lead point here (since he was from the very beginning lol) and think something like:
the dragons that survived acnologia's slaughter who were initially against humans came up with a desperate strategy to train a new dragon slayer generation in order to kill acnologia, with Igneel being the lead and strongest one there. That would make Igneel something like an enemy who lastly realized a coexistence with humans and Natsu the key role that took his power (and he is prob. the strongest of the dragons or sth, not counting acnologia obv.) to save his ass (and d ass of all dragons. and lucy. mmmm)
I am too lazy to read all the comments before so sry if there's a repetition.
