I'll get yelled at for posting this instead of updating 'Broken' but it's been in my mind for weeks and I can't focus on anything else so I'm writing this to get it off my system! Hope you enjoy

**************************************

The scene would be idealistic for a trip. A snowy mountain, trees letting in just enough light to seemingly create a halo. Giving the place an ethereal, magical sensation. Like a creature of the myths has taken residence here. But then reality would come crashing down as just a little farther down. An ongoing battle was going on. Fallen comrades laying on the floor, blood tinting the once pure white snow.

Gajeel spits out blood as he glares at the Alvarez troops. The mages of Fairy Tail and Sabertooth were too weak to continue this battle. They were backed in a corner and were trying to hold on to what little power they got before they were overrun.

Gajeel was ready to send off another dragon roar along with Sting and Rogue when Lily grabbed his pants. He looks down at his partner confused, the other two stopping as well. "Gajeel....doesn't it feel kinda hot here?" Lily asks his friends with a deep frown. The other wizards just then realizing that indeed it was getting increasingly warmer around here. Which must have been a mistake on their part, maybe they were getting so weak and cold that even the snow felt warm to them.

A worrying thought really. But none of them had enough time to ponder on it as the Alvarez troops went to attack them. Only to be stopped as they watched their weapons melt in their hands. "What is going on here?!" One of them yelled with a deep frown under his mask. This was not normal. Should not have happened. Was one of their master's around here?

Steps. Slow, steady steps were heard. And a sizzling sound accompanied them. Sting glances off to their left, trying to see but his vision was blurry from the blood that run down his eye. He was pretty sure the hits on his head weren't helping his situation either.

Flames. Black flames was all they saw as a hunced over figure started getting closer. The heat radiating heavily from him. The snow around him evaporating in an instant, the sizzling sound coming from it. Clawed hands and heavy steps all Sting could make out from what he could see.

"Who are you?! Are you with them? If so, prepare to die too!" An Alvarez soldier was heard from somewhere off Sting's side. The figure stopped after the yell, he was several meters away but they could still feel the scorching heat his very being seemed to radiate.

Red eyes. Blood red eyes is what greets everyone. And not the kind red eyes Gajeel seemed to have. These ones screamed bloodlust. The figure straightens up, looking at them now more clearly.

Natsu's familiar features is what greets the wizards. But Gajeel held back from being relieved, as did the other Fairy Tail mages. This wasn't Natsu. Something was amiss. And that something was quickly revealed.

Natsu's mouth opened and forth came a roar, dark and ominous. Nothing like his usual strong dragon roar. This one...fitted a demon better. In the new light, they got a better sight of him as well. His nails had turned into dark claws. His skin, exposed from the shirt having burned off from the extreme heat, was marked with black tattoos that resembled flames. The very same flames that were licking up his skin, their heat didn't seem to bother their fire dragon slayer. His eyes had turned blood red, a wild look on them. Like a beast, ready to tear and harm and kill. Two horns, black in the colour as well, coming from the sides of his head.

His left hand came up. Fire gathered at his palm. "EVERYONE DOWN!" Gajeel yelled, the mages quickly falling down. The Alvarez troops weren't as smart. Instead they went on to attack the slayer. Only to be met with a pillar of black fire, going straight at them. Fairy Tail and Sabertooth wizards only heard screams of pain.

Lector dared to take a peak after the fire seemed to have stopped. And what he saw would scar him for life. The soldiers that hadn't instantly died from the impact, were screaming in agony as the black flames ate them away alive. The flames dissapearing only when even their ashes seemed to have dissapeared. The trees were burning too but it seemed to die down sooner, leaving only big scortch marks behind.

Deep breaths met their eyes. When they all looked up, they saw those dark red eyes meet them head up. He walks closer. Rogue was the one closer to him. Natsu raised his hand when he was still a few feet away from the dragon slayer, Rogue getting ready for impact. Instead he was shocked when Sting had yelled "Frosch, come back!"

Rogue gasped and opened his eyes. Frosch, his little exceed was standing in front of him, even coming close to Natsu and hitting him. Despite his paws and favorite onesie burning "leave Rogue alone!" Frosch yelled with tears at his big eyes. "Frosch loves Rogue! Frosch won't let you harm him!" He yelled.

Natsu seemed to watch him with a raised eyebrow. His hand reaches down, the flames dying down as he picked up the cat. He seems to stare at him confused, his claws holding the exceed painfully.

Natsu turns his eyes towards Rogue. He didn't seem to realize who they were. Whatever overcame him was strong and didn't let him remember. The demon hand throws Frosch to Rogue, the mage quickly catching the exceed. "Frosch! Are you okay?" He asks worried.

Natsu stares at them emotionless, then raises his hand towards them. With a wave of his hand, his usual colored flames surround them. His last words towards them was "you should take better care of your family". When the fire died down, there was no sign of them.

Farther away. In all of Fiore. A message reached the guilds wizards. It was Warren, sending out an Urgent Message
"Mina! Retreat! Get away from the battlefields!" He yelled. Several protests were heard. Almost all battles were won! Why retreat now?! His next message made everyone freeze though.

"Because it's useless! This war has ended.....' his voice shaking as he added the last part "E.N.D. IS AWAKE!"

------

Gray was walking towards where END was supposed to be. His eyes hard and determined. He had just finished his battle with the Emperor's right hand man. He was bruised up and had several injuries but he didn't seem to care. Betrayal and anger all he could feel. They had taken Natsu in, he was one of them! And he was secretly with their enemy all along. Heck he could even be a spy to Zeref!

His eyes had an unmistakable fire in them. He was ready. He would fulfill his promise to his father, he would take the demon down. Then his father could finally rest in peace.

He felt Natsu before he saw him. The heat the fire mage always seemed to radiate was stronger by at least tenfold.

The demon stops several meters away from him. He looks at him with an almost bored expression. Like the fact that he was standing in front of him pissed him off. "Step aside" the black figure orders.

Gray stands his ground though, letting his demon slayer marks to spread more on his body. Covering over half of his skin. "E.N.D. your reign ends here. You have caused enough pain...i'll do right by my father and kill you, you traitor!" He yelled as an ice sword appears in his hand "This is my, no. All of Fairy Tail's revenge for your betrayal!" He yelled and went to attack.

Natsu hadn't moved the whole time. But when Gray made the move to attack him, he raised his hand, black flames gathering at his hand. The pillar of black flames was aimed straight at Gray but never reached. E.N.D seemed confused by that when he heard someone yell "Erza!"

Yes the scarlet warrior was standing in front of Gray. The huge shield he had to block Phantom Lord's attack standing between them and E.N.D. Their only protection and it was burning away fast "I won't let you die here!" She says "there are no signs of Gajeel's team...nor from the Alvarez soldiers" she explains then glares towards Natsu, who was just standing there seemingly perplexed.

"He single handed annihilated such a large group. And look at him! Does he look tired to you?" Gray frowns and looks at Natsu. The demon didn't seem to have even broken a sweat from his fight. Despite the huge amount of power it must have taken for him to take them down.

"So I'll fight with you! I'll keep him distracted so you can land in your hits okay?" She says. Finally dropping the shield before the fire reached her. E.N.D looked at them with an almost bored look. But he didn't move to attack them.

So the two wizards did. Erza went first, a row of 7 swords going straight towards Natsu "dance, my swords!" She yells and attacks the demon. Her magic was strong enough for now that the items didn't immediately melt away. But Natsu didn't make any move to stop them either, instead following her with his eyes and body. As if awaiting her hit.

Instead he was hit from behind by Gray, sending an ice grayzer towards him. The ice had melted before the sharp ends managed to hit him. Natsu looks behind him to notice the ice and frowns. He lets out another loud demon roar before he took to the skies. The fire on his skin had died down a lot now, revealing a pair of big dark red wings behind his back. Their shape very dragon like and it even seemed to have scales on the top.

"Fire....demon's roar!" Came the yell from Natsu as his roar manifested, aimed straight for his guild mates. They managed to evade it but just barely. Instead, the pillar of fire seemed to go on and instead hit the Alvarez troops behind them, screams of pain and agony following the end of the fire.

"Ice demon make, Lance!" Gray yells, several purple iced lances firing at Natsu. Erza sending her own attack, a fireproof spear that she hoped would at least make it to Natsu to hit him. Natsu, on his turn, moved his left hand on a wide arch, fire following it's path. The fire blocked their attacks in place.

"You annoy me..." he says, it was loud enough to be heard by the two. He raises his right hand, now the two noticing that the Fairy Tail mark was gone. On it's place, the Tartaros guild mark was standing proudly on his skin. "Destruction" he says. Giant fireballs appear on the sky and come falling down. They couldn't evade them all.

Gray had managed to evade about four but the last one was about to hit him. Instead a giant figure covered both of them and a moment later, an all too familiar voice was screaming in pain. The master of Fairy Tail guild, Makarov Dreyar was standing between them and the onslaught of attacks.

When the yell reached E.N.D, the fire instantly stopped and died down. Makarov's back was covered in a number of burns, going between 2 to 3 degree.

"Gramps!" "Master!" Erza and Gray yelled at the same time as they realized what had happened. They moved back just in time for Makarov to fall on his knees but not shrinking. "Run you foolish children!" Makarov yelled at them. The two wizards were ready to protest but Makarov cut them off "you'll do as I say! I am your guild master!" He tells them.

The two didn't want to but backed away from the fight. The giant's wrath would be a sight to behold. They were sure that not even E.N.D would be strong enough to defeat him. So they joined the other Fairy Tail wizards that weren't all that far away. Curiosity had of cource pricked at their side and decided to come just to get a glimpse of the demon.

E.N.D stares down at Makarov, seemingly bored. But he didn't attack yet again. "Well demon what are you waiting for?! Attack! I won't let you harm any of my brats!" He says, facing said demon. Furry in his eyes but also sadness at seeing someone he considered one of his brats be turned into such a despicable creature.

E.N.D on the other hand seemed to just stare at him then lifts his head and sniffs around. Makarov got bored of waiting and decided to attack himself. His giant fist was aimed for E.N.D, the demon flying out of the way. He sends more fire towards the master; burning his arm and park of his neck.

The old man screamed in agony from the pain but still went for more attacks. Each attack was met with a counter attack of flames. Natsu was too fast for him to hit, and he was especially fast on the air. 

The fight lasted mere minutes. Makarov ended up collapsing to the ground, his old body was too tired to continue. E.N.D got ready to send off the finishing blow. But a yell, stopped him. He looks to the side to see a blond male yell at him to leave the old man alone. E.N.D tilted his head in confused as he saw the following interaction

Laxus, was being held back by Gildarts, Erza and Mirajane as he tried to break free "leave my old man alone you demon!" He yells and tries to send off another attack on him but he was too run dry. He ended up coughing from the effort and falling down. But his eyes, determined and full of hate still followed him around.

Natsu turns his eyes between the old man and Laxus a couple of times. Then he landed on the ground ever so elegantly. His steps take him towards Makarov. Now the whole Fairy Tail guild was ready to interfere. None of them wanted to loose their master. Not again, never again. Lucy and Happy were the only ones standing to the side, unsure of what to do.

The mages run off to attack Natsu as the demon touched their master and his whole body was covered in flames.  Natsu had turned and was about to attack them when Laxus yelled "wait!" He says and walks closer. The others awaiting for his instruction with batted breaths. Natsu merely sidestepped the big body laying in front of him and started walking away.

"You idiot! Laxus he's getting away!" Gray says. He wanted revenge. Revenge for the fallen friends on the mountain, for Sabertooth. And for Makarov just now. "Open your eyes and ears Gray!" Laxus yelled back. Makarov turned back to normal but his marks... they were all gone.

"The old man" Natsu's voice cut through the silence of shock the others seemed to have. "If he's as important to you as he seems. You should take better care of him" he says then turns to look back at them "you need to take care of your family" he states then continues to walk away. Happy had started to cry then flew away from the group. He yelled towards Natsu

"E.N.D!" He yells and the demon stops. He didn't turn to face him this time but he obviously listened, a small incline of his head towards him the only real mark of the fact. Happy was sobbing as he continued

"I...' he rubs at his eyes then yells at him again "i'll make sure you'll never have to be apart from your family again! Fairy Tail will make sure you'll finally rest in peace!" He says. The demon didn't seem to move for awhile then a quiet chuckle was heard. Only the exceeds and dragon slayers managed to hear it

"Fairy Tail huh....you sure are an interesting bunch" he says then turns to look at him. A warm look in his earlier cold eyes and just as warm a smile on his lips "thanks for your help" he says then his wings spread wide. The demon turned his back to them and flew away

This was the last time anyone heard or saw the pink haired dragon slayer ever again. His body lost in the battle, like Zeref's

-----

Later, after the war had ended. They managed to find Sabertooth with the other mages. Apparently, according to Rogue. Natsu's flames had teleported them away from the battlefield, to a village some ways away from Magnolia. It was abandoned but they had some rations to survive and managed to find medical supplies to get the basic treatment.

Makarov made a swift recovery with even most of his previous conditions healed. When Gray asked Laxus how he knew that Natsu wouldn't harm their master, laxus explained.

"I saw him touch his chest and pull out the flames from basically within him. It was like he was giving part of his soul to him. It was really weird" he explains. Happy would listen to it all and cry for his lost friend.

Lucy finally addressed Happy thought "Happy what you said before...what did you mean when you told Natsu that we'll make sure he rests in peace?" She asks. Happy stiffened at being addressed but told them. He explained everything that happened during Natsu's first fight with Zeref. What they learned and everything.

Gray looked away guilty after the explanation. The demon he had swore to kill was actually the soul of a child. A child that grew up too fast and had to kill his own family.

"Do you think....he'll find them? His family" Levy asks, looking at Gajeel. The metal dragon slayer shaking his head then smiles "i'm sure he has. They both had...." he says then looks down "and we probably shouldn't be referring to him as a demon anymore too..." he adds. "Natsu...may have been more human than all of us" he says.

"He never attacked without someone first going after him. It was self defense all along. All he wanted...was to go along with his duty in peace" Lucy explains further after hearing their stories.

Makarov sighs, his long years seemingly appeared out of nowhere as he too says.
"In the end. The most feared people in the world. That could burn it down with merely a flick of their wrists. Were also human, children that lost their path. But unlike most of us" his frown deepens "they will never actually find it...so it's like Happy said. We should make sure that nothing awakens those poor souls...400 years of burden is more than enough"

2 years later

Fairy Tail and the other guilds had come out stronger after the war. They learned to forgive and not judge a book from it's cover, which helped a lot on the long run. New friends and enemies appeared down the line. But the old ones were never forgotten.

Happy had managed to retrieve Natsu's scarf and Zeref's pendant, the later a request from Mavis herself. They were put up on the second floor as a display for them that they were remembered. Zeref's was mostly put up for Mavis sake and for Natsu. The picture hanging over the memorials was a remade picture of the one that Zeref had in his pendant. Thanks to Reedus, it seemed almost alive even.

Two brothers, so different with each other. Burdened with so much pain and sorrow. Yet in the picture, as they hugged each other and were grinning to each other, they seemed just like any other person their age. And this picture served as a promise, or rather a hope. A hope that, somewhere out there. The two brothers would meet once again and finally get the happiness they deserve
