Okay this story is getting very popular mostly good reviews except you know from doom marine 54 but I couldn't care less he is really the only person who has given a bad review but talks like he is speaking for the entire fanfiction community.

However please do read if you couldn't care less about spoilers cause I' pretty sure everyone knows the spoilers so far for the latest chapter in the manga so sit back and enjoy

"My dear boy where will you go?" Makarov asked teary eyed as he was about to bid farewell to one of his beloved children.

"To see a certain black wizard…My brother Zeref." He said in almost dark serious tone with his back to his fellow wizards. The mages were left agape at what the Salamander said. "W-what do you mean your brother is that bastard Zeref?" Gray shouted towards Natsu as he was slowly walking over to Sayla but halted at Gray's word.

"It's exactly what it sounds like ice prick, before Igneel died he told what I needed to know or more precisely he showed me and I'd appreciate it if you didn't talk that way about my family Gray."

Flashback

"Igneel come on get up…g-get up don't let this bastard beat you!" Natsu shouted in between sobs. "I'm sorry Natsu, I'm sorry for everything, though you may not like it you do have one family left related by blood. Zeref…Zeref is your brother, I don't have much time left and I know you'd prefer not to have heard this but believe me Zeref had his reasons for what he became, even if you don't believe me it is true and all I can give you some fragmented memories."

A green circle appeared below when Natsu stood and a surge of magic flowed through his body, as the he felt this he started seeing memories of himself with people he hadn't seen before until they started to sink in and he began recognising the people. One was a woman of average height, she had beautiful deep crimson eyes that were rimmed and flecked with black. Her hair was cherry blossom pink, her fringe swept over one side of her face and reached down to her mid-back. She was wearing a long plain white sun dress that reached down to just above her shins, she had a slightly tan complexion. Beside her was a man also of average height, he had onyx black eyes and hair the colour of obsidian, he looked to be around the same build as Natsu and had skin of a light tan colour.

His mind clicked and he began to tear up unaware of Acnologia still overhead charging his breath attack, "Mom? Dad?" he said his voice barely audible through his emotions. The next memory came in showing a boy that looked exactly like he did when he trained with Igneel, he immediately recognised the boy that was next to who he presumed was him, he recognise the look on his face anywhere it was always the same whether he was happy or sad he always had a sly smile plastered on his face.

He wasn't sure how he should feel, this boy that was beside him was Zeref the most evil and powerful wizard in history, "But Zeref lived over 400 years ago ahhhh this doesn't make sense" Natsu thought to himself but was snapped out of his thoughts as he saw himself and Zeref running around, laughing and playing with each other. "He could see that this child version of himself was clearly enjoying playing with alleged brother and must have been about four years of age. Natsu formed a slight smile and began thinking to himself.

"If Igneel tells me that Zeref is my brother I doubt he would joke about something so serious, but the why? Why couldn't I remember something so important? He started asking himself when the memories started to speed some of which he only caught glimpses of. "A book… E.N.D… a chamber...Zeref and Igneel!" Natsu shouted out remembering some of the blurred memories he received the last one shocking him most.

Snapping back to reality he could hear and see Acnologia overhead ready to unleash his breath attack, "Shit what's happening?" he started saying in a panicked voice. "Natsu my boy I now you have a lot of question and I'm sorry that I can't answer them, so please just grant me my last wish. Save your brother, remember your words use them as your motivation to live on." Igneel said in a pained voice the very life slipping from his voice as he lay on the ground while Acnologia unleashed his attack.

"Die dragon scum!" The black dragon of the apocalypse shouted as his roar finished off the fire dragon king. His work unfinished Acnologia left, after receiving such a serious injury Acnologia was less than willing to face off against Zeref's strongest creation while only having one arm. As they creature flew away, Natsu walked up to the remains of his adoptive father with his father's last words in his mind.

He stared at what was left of Igneel's body for a few minutes before letting out a roar that couldn't be considered human or draconic, instead it was more demonic than anything. "Raaaaghhhhh!" was all that was heard for miles, the very air around Natsu seemed to vibrate as he clutched his head in his hands and dropped to his knees. "I will save him father, I will get stronger and I will grind Acnologia's ass into dragon dust!" The pinkette shouted towards the heavens as the tears streamed down his face. (This is before etherion blast.)

Flashback End

"And that is more less what's happening, Igneel told me there was a reason why Zeref has committed his past atrocities so I will believe him and grant him his dying wish… I will save my brother even if it means going against the whole world." Natsu said after explaining the whole situation to them.

The wizards just stood there gawking at his story, all was silent and Natsu was about leave as he walked up beside Sayla up. "Oi Natsu! You don't expect to believe in that crap, you can't tell me you honestly believe that shit?" The ice-devil slayer shouted towards Natsu. Said fire mage turned to face him with a serious expression etched into his face, his red eyes staring in silence so much so it was almost as if they burned through the soul.

"You're entitled to think what you want snow fairy, but yes I do Igneel was the only father I have recollection of and now he is dead so I will honour his wish, he has never lied to me before and I don't believe he would start the day I finally found him." He hissed back at the ice mage. "Try putting yourself in my shoes Gray, if you had no memory of your parents before and suddenly Ur came back after years when she left you alone only to end up dying the day came she returned but gave you all the memories of your life before you met her and ends up telling you Zeref is your brother, how do you react?"

"Of course I'd believe her, but this is…" Gray never finished because the dragonslayer continued for him "It's exactly the same Gray you just can't see that it is with puny excuse of a thing you call a brain. Doesn't matter that you don't understand, me and Sayla have to leave now if we want to catch up to Zeref so I can release him from his pain, because if I don't he could wind up releasing E.N.D." and with that the two slowly walked away although it pained Natsu to do so.

An hour after walking they stopped at Natsu's house in the forest to get a few things. While in the house Natsu looked in a mirror to see the markings on his chest, they had caught his attention earlier and he was truly wondering why they appeared on his body, that and he wanted to get a good luck at his appearance.

"Man I liked my pink hair, this colour is alright but nobody suited pink hair better than me. That aside my eyes look pretty cool and these markings look like Laxus' tattoo they make me look totally badass what do you think Sayla?" he turned to question the demon but she never answered in fact the entire walk to his house she never said a word.

"Is this really alright? He intended to fight his own friends to protect me, and now and now he has left them because of me." Sayla started thinking to herself until she heard Natsu calling her Name a few times snapping her out of her thoughts.

"Hey Sayla, Sayla are you listening?" he questioned her "huh sorry what were you saying Natsu I spaced" she replied in a dazed tone. "I was asking does this look suit me?" he repeated. Staring at him for a few seconds she nodded to show her approval. "Are you okay, if something is bothering you tell me so I'll know if I can help you? I realise we haven't see each other in what seventeen years so it may be difficult to be as friendly as we were back then but we can start by trusting each other enough to talk about our problems right?" he tells her with a sincere smile showing off his pearly white fangs.

"Is this really alright, you leaving your guild like that? I understand why they wanted to hurt me but you went against them to protect me, you left all your friends behind why?" Sayla asks the dragonslayer trying not to think that he might just be taking her along because of pity. "Of course it's alright, leaving the guild was the best possible choice, it means that anyone we come across can't relate us to Fairytail if we make an enemy of them and…"

Here it came the reason she wanted to hear but at the same time dreaded to hear, the reason why he took her with him and saved her. "And this gives us some great time to finally catch up and get to know each other properly, even if it's going to be dangerous I can't help but be excited that I finally found you after all this time and get to know you." He said continuing on with a soft voice.

"But how can you forgive my sins so easily, h-how?" Sayla replied to him starting to cry mid-sentence. Kneeling down in front of where she was sitting Natsu placed a hand on Sayla's head and gently pulled it down towards him pressing his own forehead against hers closed his eyes and began to speak. "I can because I have a few of my own, you're my friend, my long lost friend and now that I've found you I won't let a few sins scare me away, because this time I'm not losing you." His words were calm and kind with determination laced through them.

She couldn't help herself after hearing his words, she sprung herself forward toppling Natsu over landing on top him in a bone crushing embrace, well for a normal human anyway after all of the titan and Erza hugs he had received this wasn't as bad. Sayla was now lying on top of Natsu her face buried into his bare chest at such an angle that her horns rested atop of his shoulders. Her breathing became shallow as she tried to recompose herself while Natsu stroked his hand through her dark purple (almost black) hair.

The two stayed like this for a few more moments until Sayla started to speak up. "I never stopped thinking about, the entire time I was a member of Tartarus I never stopped thinking about you, because…because…" she tried to say the words but she didn't know how he'd react after all she was a demon and he was human. "Don't force yourself to say something you're not ready to, like I said we will use this time together to get to know each other better and then say it when you're ready." Were his words, they disheartened her a lit bit but 17 years was a long time apart and knew that she would need to know him better before saying anything to rash. "Okay, we'll get to know each other better we have a lot to catch up on after all." She replied to him with a smile.

A few minutes later and the pair we're leaving the house when there he stood in front of them. "Lord Zeref?" Sayla said in an almost question like tone before falling to her knees and bowing to her creator. "There is no need formalities rise I have much to discuss with you two while I'm still in control." Zeref said in a passive tone. "So is it true, are you my brother and what connection did you hold with Igneel?" Natsu questioned as he stepped forward his hair shadowing his eyes.

"What Igneel showed you was indeed the truth, I am your brother, my name Zeref Dragneel but I held no connection to the fire dragon king. Natsu what I'm about to tell will be hard to believe but you need to know this in order to release me from my suffering." The black wizard spoke calmly waiting for a response before he continued. Seeing Natsu nod his head Zeref then proceeded to tell them what they needed to know.

"Okay time is short so listen closely, Natsu we both lived over 400 years ago but one day you grew very ill and died, our parents were stricken with grief, our mother took her own life and our father left. I was taken in by the magic academy due to my proficiency in magic. I used the resources in the academy to find any means what so ever of bring you back and over the years came up with many ways to bring you back, the R-system and Eclipse project are some names you might recognise."

"The magic theory behind my projects was sound however I was condemned and was to be expelled from the academy for my blasphemous acts and slander, I mocked the concept of life and death and so before I was expelled the gods cursed me, the more I care for life the more the curse forces me to take life except my own, I have become immortal and have had to watch as the world I had loved so much rejected me. So for 400 years I researched all types of magics before eventually I started creating my demons in the hope one would be strong enough to kill me." Zeref finishes letting out a sigh.

"However it seemed like I never would be able to create an etherious demon strong enough to do so until I resorted to my last option. For the 400 years I isolated myself I learned how to preserve your body and how to bring you back, you are not fully human anymore Natsu, you are my brother my strongest creation who will someday rid this world of my existence. Natsu Dragneel you are E.N.D or to be more accurate Etherious Natsu Dragneel the only being that will ever be strong enough to defeat me." Zeref finally finishes his tone now more serious.

Sayla and Natsu both were in absolute shock, Sceptical at first Natsu didn't know whether to believe him or not, he didn't doubt that Zeref was his brother he could actually confirm it himself when he smelled that his own scent was almost identical to Zeref's. "What do you mean someday, if I'm the most powerful demon why wouldn't I be able to do it now?" Natsu questioned, it had long been his dream to get revenge against Zeref for calling forth Acnologia at Tenrou island but now that he knows that Zeref is his own brother his rather reluctant, he doesn't want to kill what is left of his family, he might in great suffering but he couldn't.

"You are my most powerful demon but if I let all that power flow inside your body from the beginning it would have destroyed you, so you have numerous seal inside your body some will alter strength and appearance while others will grant you the powers of curses. It seems that the Etherion blast removed the first seal it altered your appearance and your magical strength however it isn't enough. 1 year that's how long I can give you, I'll release your second seal but you'll have to train hard in order to control each new level of power, for when we next meet it will be on the battle field as enemies, as this curse will not simply just let me let you kill me so I must hate the essence of life in order to stay in control. Sayla take this book of demons you will be able to call any one of them forth so that Natsu can fight them to get stronger, take care of him and make sure that he is strong enough for in 1 years' time he fight not only me but Acnologia as well. Farewell for now Natsu and remember your promise to Igneel. Zeref said throwing her a book entitled ABSOLUTE COMMAND before turning to walk away.

He was stopped by a pair of arms being wrapped around him. "I promise I will save you, I don't want to kill so if there is a way to remove your curse I will find it and save as well destroy Acnologia." Natsu said hugging his brother before he started crying. "I'm afraid death is the only way Natsu" Zeref said placing one hand on that of his little brothers. "Why? Why am I destined to watch as my family dies? Mum died because I wasn't strong enough and got sick dad left you and probably died shortly after, then Igneel died and now, now you have to die by my hand please I don't care if I have fight God himself I can't lose any more of my Family. Natsu cried into his brother's shoulder.

"I have lived a long time Natsu longer than anyone else, I've seen so much of this beautiful world, always thinking there nothing left that could surprise me but it would always still manage somehow. I've never heard of a way to remove my curse, it's one of a kind inflicted upon me by the gods themselves. Please Natsu I don't want to destroy any more of this world, I don't want take another life, death is the only way." Zeref replies in a saddened tone.

At hearing those words Natsu's head dropped as he let go of Zeref. "However that isn't to say I've looked everywhere, your best bet is to go to where it all started, the Mildian Magic Academy, the name of the curse is called Ankhserum's Wrath, (actual name of curse and academy from manga) if there is anything about this curse it will be there but don't get your hopes up that place is in ruins now it's just a little hope for if nothing, though I'm still positive that death is the only way." He said trying to give his brother a sliver of hope before disappearing in a black wisp of flames.

"Natsu." Sayla spoke up in concerned tone before placing her hands on the kneeling dragonslayer who then placed his hand on top Sayla's taking it in a firm grip. Dropping down to his height Sayla then placed both her arms around Natsu in a tight embrace which he returned leaning into the crook of her neck. "If there is a way to save lord Zeref I will help you find it I owe him everything, he is my creator and he brought you back from the dead without him I never would have met you, together we will find something because I am your friend and will always from now on be by your side.

Wiping the tears away from his face Natsu manages to form a smile and recompose himself. "Thanks Sayla, I feel a much better now that I know I have you with me." He said his smile never wavering causing the demon to bush a little at what he said. "So 1 year of training as a half demon, I want to save my brother but if death is the only way to release him from his pain then I don't have much choice as for Acnologia he will be the primary focus for my training as I have no reservations about killing that bastard." Natsu said in a neutral tone while clenching his face.

Then releasing a long breath he turned to take one last look at his house that was built so many years ago. "Sayla lets go we'll need to find somewhere far away from people if we're going to be fighting and releasing demons." He said before walking away with the demoness. "I believe I know somewhere that should be good enough but it will take maybe a week or two before we get there." She said in response hoping her suggestion would please Natsu. "Great that saves us the effort of having to find a place." He replied before the pair's figures disappeared in the distance.

Meanwhile at Fairytail

At Fairytail Laxus and the Thunder Legion had been cured from the anti-ethernano poison, after hearing the news of what happened Laxus was ashamed of himself for not being stronger and astonished to hear that a battle between dragons from this timeline took place and that Natsu was in fact the brother of Zeref. After Makarov had confirmed his grandson's disbeliefs he took the Thunder Legion to go train so that he could become stronger to protect those he cared about.

The guild was once again under reconstruction after the war with Tartarus most of the members stayed to help with the build, but the guild's main forces went away to train themselves to avoid something like this from happening again. These forces included team Natsu bar Natsu, Laxus and the Thunder Legion and the Strauss siblings and of course Gildarts who was still roaming the continent unaware of what happened.

"Natsu I hope you know what you're doing? Please come back safe my boy" were Makarov thoughts as he was using his titan magic to speed up the build.

At the same time in a far corner in the continent of Ishgal

In a lone cave a cloaked man sat his legs crossed on the stone floor as he stared at the black wizard Zeref. "What do you want black wizard?" the man said in a low angry voice. The man had long wild hair black as obsidian that reached down to base of his back. His eyes matched the colour of his hair, his skin was lightly tanned. Most noticeable of all were the swirling blue tribal tattoos on his face and arm.

Zeref coyly smiled before replying "nothing much just came for a little chat, how's the arm Acnologia or would you prefer it that I called you Father?" "You are no longer any son of mine, now get to the point of why you're here." Acnologia growled fiercely. "My, my, it seems nothing gets by you as usual dad even when I was a child I could never pull anything over your eyes."

"The point of our meeting is simple, you desire to be the strongest but as long as I am alive you cannot reach that level, I however desire for your destruction so we are at a stalemate I am immortal so you can't kill me and I can't kill you as my death magic doesn't affect you. As much as I want to die I can't however I created the demon E.N.D to do so for me, yo may know that demon as Natsu Dragneel." Zeref paused for a moment to see the visible rage on Acnologia's face.

"So this is my proposal give Natsu one year for him to become strong enough to kill me and then you can fight him and take your revenge on him after all you despised the life of your youngest son because he died from an illness you cause that drove the only women you ever loved to take her own life, do we have a deal."

"That boy was weak I never would have expected his body to reject the dragon blood like it did, it was him who drove me away but you who loved your brother so much even after your mother's death continued to care so much about him that it drove you to find a way to bring him back, We have a deal for 1 year I will leave Ishgal but when I return I will take my revenge whether he is strong enough to defeat you or not.

CHAPTER END

Okay that is the third and longest chapter yet, sorry for the delays in my update I had a couple of new ideas for the stories so that took some time to sketch out a solid plan for. As for the whole Acnologia thing being Natsu and Zeref's father well that is a predication really or more of a guess, if it is true then that would be a deadly but expected plot twist later on in the manga. I hope you guys enjoyed this chapter and keeps you tied over until the next chapter so for now chaosdragonslayer 777 signing off
