Acnologia is one of the main villains of Fairy Tail so hes probably only out temporarily to show how powerful Igneel is and later he will get back up again and attack Fairy Tail and the dragons. Seems its almost time for E.N.D to appear and after the stuff with him is over we hopefully will get an explanation for why the dragons disappeared.
