Dragon slayer to Shadow King

Natsu was in complete shock about Igneel living inside his body. He almost missed the battle between his dragon and Acnologia. Watching a fight between dragons, such as power and rage, is a sight. The roars of the two dragons sent fear into all the wizards left standing; one final blow and both dragons started to slow down. The dragons showed signs of fatigue, Igneel falling first, knowing the last blow he had hit would be fatal to Acnologia. Acnologia, having learned that this would have happened at some point, used the last of his strength to blast the magic guilds to pieces. Natsu noticed this and ran in front of it.
