It was very hard to decide what to change and what not to about this arc as this is such an awesome arc but I had to change it somewhat so that it will fit this story, but I somehow did it. Please tell me if I did alright or not. I was really nervous while typing this. Oh for all of you I posted another Fairy Tail story. Please check it out and tell me how it was. It can be taken as a sequel of this if you like. But it will be continued in this too so don't worry. It is like a side story to this and you need have no knowledge of the other to enjoy this.

Oh I skipped to chapter 413 for your knowledge. Everything happened the same as in manga till up there. I am being lazy and not typing that whole thing up but the changes start from there so you need to be really updated

Disclaimer: don't own it but if I did you would have seen the changes.

The battle against Tartorus was hard fought. In the sky the battle was raging between Igneel and Acnologia, Natsu meanwhile cursed END for making Mard as the guild master in his stead that man was crazily obsessed with END, even going as far as to activate face to get him to come out. With great difficulty Natsu and Gray had managed to subdue long raven haired man. Natsu cursed not being able to use his curses as END was currently out and limiting powers as his current body did not allow it.

It was a miracle that the demon had not recognised on site, maybe because it had been too long since he had last felt him or because his demon part was god knows where, but he knew that the demon would return. They were part of the same body after all. A wave shook him, but it only looked like he had felt that. He could feel magic deplete from his surroundings like in Edolas. Suddenly Igneel took down Acnologia.

"Don't give up humans" the fire dragon roared and Natsu smiled a smile, feeling a pride a child feels for his parent and a large numbers of dragon filled the sky destroying Faces. But to Natsu's horror Acnologia again attacked Igneel

'Why are you doing this? Is that demon still controlling you? Making you fight your own brother? Why?' Natsu asked torn whether he should take pride in Acnologia's power or feel horrified as Igneel get beaten. 'The book. He asked me to get the book of END. A load of good it will do with that maniac running wild, but still it is Igneel's wish' he roamed his eyes around in search of the book to see it in Gray's hand. He did not even pay attention what the twin dragon slayers were saying but watched with wide eyes as someone took the book from Gray's hand.

"This book belongs to me" with the cape flowing around him, in all his glory appeared Zeref, causing everyone's eyes to be glued to him "so I'm taking it back" the fear and surprise could not be mistaken in everyone's eyes "it's really important you know"

"Zeref" the whisper broke out from Natsu's lips looking at the other will disbelief in his eyes and he could feel others around him staring surprise as well.

"This guy" Sting said and the surprise was evident in his voice, quite unmasked. Rouge was also watching silently as the raven turned toward the demon.

"Mard Geer, you did well. You were just about to revive END fully" he said, the expression on his face kind to bide his true intentions.

"Mard Geer could realise what you wish" the demon said raising his arm but in next second he vanished in smoke in form of a book.

"You can't. You did not even realise that END was fully free" he said as the book vanished, the slayers looking at him with disbelief.

"You made him" Rouge commented but the dark wizard just smiled.

"Yes, but I did not need him anymore so I stored his book in my personal library" and he turned toward the pink haired dragon slayer, "I wanted to finish our fight, unfortunately Acnologia got in the way" he said looking at the pink haired wizard square in the eye.

"What do you mean?" the pink haired younger asked as he looked at his kin who merely smiled.

"If you survive, despair will follow you. When the humans abandon you come back home. It is the only place you will be accepted for who you are" he said even if the shouts of we will not abandon Natsu and What did he meant reached him.

"He took the book with him" Gray said angrily watching the man walk away, suddenly a large band shook the place. Natsu looked up to see Igneel pressed into the ground by Acnologia. Igneel was telling the second reason why he was sealed into Natsu and that very second Natsu realised a horrific fact, only one of the two dragons would survive. He would lose one of his fathers, no matter who won. Just when Natsu had made his decision that he must protect everyone from Acnologia it happened. Acnologia tore the fire dragon's right side causing him to fall. Acnologia launched another attack at the large dragon.

"I've been watching you this whole time. Natsu, you gave me the power to love humans" the big red dragon said as he was still falling. Natsu felt tears hit his eyes. 'I did? Then why not Acnologia too? Why not him? I know him. There must be one hell of a reason for this but, can I forgive him?' the thoughts plagued him, he ran toward where the dragon lay.

"Dad?" he called out "You promised me that you won't go anywhere. Don't break your promise. I" a sniff escaped him as he tried his best to keep his tears at bay. "I've been looking for you for so long. I…I learned how to write and my magic is so much more badass now. Not to mention I made a lot of friends. I got a job too…I" and the break was evident in his voice, his raw emotions escaping him

"I….I..." now the tears marked his cheeks but he tried his best not to break not to break, I have things I want to share with you. Igneel" now the tears were escaping continuously from his eyes, sorrow filling his whole being, yet not being able to hate the one who did it. Only feeling self-hatred for not being able to prevent the death of his foster father. "I'll get Acnologia for this" he whispered. A figure approached him and pulled him into a hug.

"Let it all out" the whisper broke the dam of emotions Natsu had, and he began to cry in earnest soft hands petting his head. "Shhh. I'm here. I will not leave you. After all we are one and the same" he consoled the wizard trapped into the child's body. It was a long time before Natsu calmed down, the demon stayed till he exhausted himself and fairy tail found him before he faded back into the child, not before smirking at the exceed ho watched from afar.

So done. Hope you liked this. This was the most difficult chapter to start that I ever wrote. Feedback will be appreciated. So do you think Natsu should leave before Fairy Tail disband and get the news on t=his journey or be there when it disband?
