Chapter 1

E.N.D

It all had happened so fast. It was not too long ago that Lucy was fighting for her life against members of Tartaros, swimming in poisoned water, and losing all of her magic to Face. Even though the Master had ordered everyone to return to the destroyed guild hall, Lucy was too worried about her teammates that were left behind, risking their lives to defeat what was left of Tartaros. Erza was fighting Kyouka to prevent her from activating Face, Levy and Gajeel were on their way back to the guild to give the final ingredient to Porlyusica to save the Thunder Legion and Gray and Natsu were fighting Mard Geer, attempting to retrieve the book of E.N.D. She had told everyone that she was going to go back and look for the others, hoping she would be able to give a hand.

"No way! It's too dangerous now, especially since you don't have your magic." Duranbold said strictly.

"Lucy, we need to head back to the guild. The Master is waiting." Lisanna added.

"I can't! I'm worried about them. We are a team and they need my help." Lucy attempted to head back to the fighting grounds, but Lisanna grabbed her wrist, preventing her from leaving. She looks back at the Animal Soul wizard and saw her face filled with worry. "Lisanna…" She said in a hush. "I have to go."

Lisanna saw the determination in Lucy's eyes, the same determination that she has seen before in other members in Fairy Tail, even in her own siblings, in her own self. She knew there was no changing her mind. Lisanna softened her grip and held Lucy's hands into hers. "Don't forget your promise."

That is all she said, and that is all Lucy needed to understand what she meant. "Don't worry, I won't." She slowly took her hand away from Lisanna's and started running, never looking back.

Lucy kept her eyes on the sky where two dragons were fighting what seemed like to the death. She knew that one of them was Igneel, Natsu's father, and wherever he was, Natsu would follow. "I'm coming Natsu." She kept running, no intentions of stopping. However, because all of magic had been taken away from the continent, she was too weak and was slowing down. The dragons' roars, even at a far distance, would periodically shake the ground, resulting into tumbles. But she would keep moving, and even if it meant crawling, she would get to him.

In the back of her mind she would think of the others. The minute they had learned that Face was successful, she was worried if something had happened to Erza and the others. It was unavoidable that she would think the worst would have happened, but she had to remain focused. There was no question she would go to their aid, but she had no idea where they were located. "No." She huffed. "They're okay." and she marched on.

With every step, she was getting closer and closer to the two dragons in the sky, so she knew that Natsu was somewhere close by. The voices of two shouting men were heard in the distance, but she could not quite make out whose they belonged to. A little more walking and she saw Natsu and Gray in the middle of an opening, both in one piece. She wanted to yell out of joy for finally finding them and seeing that they were unharmed, but nothing would come out. She was too choked up and exhausted to even speak. What amazed her the most was the unconscious body of the king of Tartaros, Mard Geer, in the near distance. They both managed to beat him.

"Give me the Book, Ice Princess." Natsu yelled.

"I told you no. I'm going to destroy it. I promised my father." Gray replied a little more calmly.

"I did too, now give me the Book or I'll roast you."

"Go ahead ya Pyro, but I'm not giving it to you."

The scene before her made her giggle. They finally were able to defeat one of the strongest opponents of Tartaros and retrieve the Book of E.N.D., and there they were fighting like they always did. She was happy.

The two boys looked in her direction after hearing her laugh and they both had smiles on their faces. "Lucy!" They said in unison. Completely forgetting about their argument, they walked towards Lucy.

"We thought you were with the others." Natsu said.

"I came looking for you in case you needed help. But I guess you have everything under control." She laughed again.

"Yeah, we just-" Completely caught off guard, Gray lost his balance and fell to the ground, releasing the Book which flew through the air. "What the-?" Gray looked behind him and saw that his ankle was wrapped in a branch filled with thorns, much like the ones Mard Geer was using to fight them. He look over, and saw Mard Geer barely conscious, smirking.

"I got it!" Natsu yelled. In one swoop he had the Book in his hands. Relieved, Lucy lets out a sigh. She knew that the seal was far too weak to hold E.N.D.'s powers now that all of the magic on the continent had vanished, and the Book being opened in its current state would have been disastrous. Natsu smiled his characteristic grin. "See, told ya." He laughed.

"Nice going Flame Brain, now give it back." Gray said.

"Flat chase you clumsy popsicle." Natsu snapped back.

"It will not matter." Mard Geer chuckled in the near distance, grabbing everyone's attention. "For it has already begun."

"Wha-?" Natsu looked at his wrist and saw black marking coming from the book covering his body, slowly rushing up his arm. "What is this?" It wasn't until it reached his shoulder and his chest that Gray knew what was happening.

"Natsu, no-!" Gray was silenced when he took a hard hit in the back of his head, blacking out.

Natsu screamed in pain. More than he had ever before. The transformation that he was undergoing was even more gruesome than the yells of grew rapidly on his fingertips, sharp fangs emerged from his mouth, and massive horns sprouted from his head. And that was only the beginning. Scales appeared on his skin all over his body. It was like a dragon force transformation just like before, only more terrifying. Lucy could not believe her eyes. Fear was surging through her whole body, making it difficult for her to even stand. Her friend was in pain. Natsu was in pain. She didn't know why. All she knew is that she wanted it to stop. She took a few steps forward, slowly coming closer to Natsu. With the pain, he could barely keep his eyes open, but once he saw Lucy coming closer and closer, he got scared. He didn't know if he could control himself any longer. Lucy was just a stretch away from reaching over to him when he forcefully shrugged her away. "No, Lucy! Stay away! I don't want to hurt you!" He pleaded.

Lucy saw the horror in his eyes, the fear he was feeling. He was afraid of himself. She felt hurt. She didn't want him to feel this way. The Natsu she knew was confident and would never hurt his loved ones. "Natsu, don't be silly." She smiled, trying to avoid reality. "You don't have to be afraid." She reached over one more time, just inches away from touching his shoulder. "Natsu is Natsu. Always."

In an instant, Natsu's hand grabbed Lucy's and held it tight to the point of bones breaking. Lucy let out a sharp scream from the pain. It still wasn't broken, but the pain was unbearable. She looked over to him and saw his onyx eyes burning blood red, much like a monster's. His deep hoarse voice that was filled with malevolence spoke in a way that made Lucy shiver. "You sure about that, Luce?" He chuckled.

It was the same voice that she knew and loved, but it was definitely different. "Natsu?" Her voice trembled.

"Guess again." He laughed almost bringing her to tears. "I am E.N.D." he wrapped his scaly arm around her petite waist, bring her closer to him. "and you are mine." Flames engulfed his body, along with Lucy's too, and in a flash, they disappeared into thin air.

I've been OBSESSING over this whole E.N.D. theory, and Hiro Mashima is getting on my nerves that he is not revealing his true identity. So I decided to go along an write this story that has been on my mind for months now. What really made me write it is that I've been waiting for over a week for the Chapter "The Book of E.N.D." to come out and it hasn't yet. So lets see how close I am to the truth.

Now here is were you come in. I will be updating very frequently on this story until it is done (It won't be really long.) There have been many theories from different people and I want you guys to share your ideas with me so they can appear in the next chapters. Just review, and if you want to surprise our fellow readers, feel free to PM me. (I would like to keep it in 3rd person perspective, so keep that in mind.)

So for how this chapter ended, I'm not sure if I should do anything like killing off Lucy or anything like that. I also don't trust myself with smut, but if that is something you would enjoy, I could certainly try. (Whatever your dirty little minds desire :3)

As always, Favorite and Follow.

Love ya
