I'm here with a new story! I've wanted to write a story about E.N.D ever since he was revealed. Of course my other story Dragon King of Fairy Tail will still be on going, I just couldn't get this story idea out of my head and had to write about it. Tell me what you think about this prologue

There wasn't much to look at; those were the first thoughts for Mavis Vermillion as she was standing in front of an empty looking mountain. There was no grass, no tree's, not even the occasional roots; just stone's and pebbles, Mavis glanced back and overlooked the small town below. She was currently on a job request, a difficult one at that, she had been given questioning looks due to her age and the fact that her guild has only been established for a couple of months, but she merely brushed them off; after all if she could get the job done, none of their opinions mattered. This was actually going to be her fourth job outside of Magnolia; she was used to it but was still a little nervous. Her job was to exterminate a demon that had been terrorizing the town; a job that was considered to be given to the higher level mages and not normally given to guilds that have been established for such a short time, but from what she has heard the mayor of the town has been getting desperate and has requested the job be delivered to every available guild. She took a deep breath before making her way up the mountain; from the information she gathered, the demon terrorizing the town was incredibly powerful, in fact many high level mages have been killed trying to complete this job, the council has even sent squadrons of rune knights to try and subjugate the demon but none returned alive; this job request was the mayors last attempt before the town would be forced to relocate.

Mavis made her way into a cave, she could feel an ominous presence coming from within. Taking a deep breath Mavis walked deeper and much to her surprise the deeper she traveled the brighter the cave started to become. She started to come across books littered across the floor, careful to not step on them, Mavis found herself in a large space, towers after towers of books piled all over the place, she looked around,

"you know, I've been wondering why demon's are always depicted as evil in these story books" a voice said catching Mavis off guard, she didn't say anything instead she tried to hide her presence,

"no need to be shy, I don't bite" Mavis squeezed passed the pile of books and found a young man sitting on the ground with multiple candles lit around, the man in her honest opinion was quite handsome though she did find it odd that his spiked hair was pink,

"hmm, so they decided to send a little girl this time, the mayor must be really desperate" he commented looking at Mavis,

"you must be the demon" she asked ignoring his comment about her

"bingo! You get a gold star" he closed the book he was reading, "but answer my first question, why are demon's always depicted as evil in stories?" Mavis was hesitant in answering; it was obvious that her next words would be the difference between life or death,

"it's a cliché" she said,

"a cliché?"

"that's right, most stories nowadays use cliché's to bring forth something familiar that the readers can identify, it becomes a template and prevents stories from being too foreign. In the end it set's a genre" she said hoping that her answer would satisfy the demon. Much to her relief he smiled, nodding in approval,

"good, good, you pass" he said giving her a short clap, "now tell me; what can I do for you?" Mavis paused, glad that she didn't anger the demon; despite his calm and playful look she could tell that the man in front of her was incredibly powerful,

"I am here to have you relocate" she said, the demon grinned,

"interesting choice of words" standing up, the man stretched, "but like I said, no need to hide, you're here to exterminate me" he spread his arms out, "well then give me your best shot" Mavis stepped back, unsure as to how she was supposed to react, there had to be something she was missing,

"I would like to try and not use violence" she said,

"hmm, an unusual reaction, normally people would jump at the chance to kill me" he let his hands fall by his side, "tell me, what is your name?"

"Mavis Vermillion" she said, the demon gave her a mock bow,

"greetings Mavis Vermillion, you may call me Natsu Dragneel or E.N.D; whatever fit's your taste" Mavis blinked, "so tell me Mavis how do you plan to remove me from this place?" honestly Mavis didn't know, everything that has happened so far has surprised her, she honestly didn't think that the demon would be so civil which was unlike any of the information she gathered. However a thought appeared, something she and Yury did when they first met,

"how about we play a game?" she finally said

"a game?" he said, judging by the smile Mavis guessed Natsu was interested,

"yes a game. This is a game of guessing the truths about one another"

"interesting... please explain" Mavis nodded,

"for example, let us say it was my turn, I would say 'you are a male', if what I said was true it would be your turn" she explained,

"so I would say something like 'you are female'" Mavis nodded

"that's right, the first person to guess wrong loses and of course you are not allowed to lie" Natsu crossed his arms,

"hmm, that sounds a bit too easy, there must be a catch" Mavis nodded,

"there is one additional rule. You are not allowed to say things that are related to each other, so things like 'you have eyes' and 'you have hair' otherwise the game will just keep going on forever" Natsu nodded,

"sounds fun!" he crossed his arms, eyes focused on the young girl before him,

"would you like to try a dry run?" Mavis asked,

"no, I think I've understood the game" he said, "but what do I get if I were to win?" Mavis' gaze looked into Natsu's

"what do you want?" she asked. Natsu grinned; he honestly found the girl in front of him intriguing; she was very different when compared to the other human's he's met,

"if I win, I want you to become mine" Mavis' eyes widened, a light blush formed on her cheeks, she took another step back,

"wh-what are you saying?" she stammered,

"I find you interesting, and I like interesting things" a little stunned by his words, Mavis tried to convince him,

"maybe you would like something else?" Natsu shook his head,

"I want you if I win" Mavis swallowed hard knowing full well that she couldn't change the demon's mind; the only thing she could do now was to make sure that she won.

"Then I will go first" Natsu said, "you are a female mage" he started with something simple, a smart move Mavis thought,

"you have pink hair" she too started easy; in all honesty she could have pulled the move she did with Yura, but something was telling her that Natsu also had a trick up his sleeve,

"you like fairies" he said, Mavis was surprised, she didn't expect for him to know that about her. Natsu smiled pointing at her clothes and bracelet, "you should probably wear less obvious accessories if you're trying to hide it" Mavis looked down at the fairy embroidery that was on the side of her dress and the small fairy shaped jewel hanging from her wrist; she blushed knowing that she was careless. She sighed, she needed to step up her game, she glanced around and took a good look at one of the open books Natsu had set down,

"all these books were written by you" Natsu smiled, bingo, she fell for his trap,

"you are correct in saying that they were written by me" his grin formed into a smirk, "but you are incorrect in assuming that these are books" as he said that some of the books started to glow before morphing. Mavis was now surrounded, "these books are in fact demon's"

"Master E.N.D" they all said in unison,

"this girl, do you wish for us to dispose of her?" a woman said her most notable feature was her hands which took the form of sharp scaly talon's. Natsu shook his head,

"no Kyouka, Mavis and I are playing a game" he turned to Mavis who was looking between the demon's warily, "and it would seem that I have won"

"not exactly" she said; Natsu raised a brow, "they may be demon's now, but from what I observe their existence is derived from the books you wrote. Meaning my statement was both correct and incorrect"

"I suppose you speak the truth, which would mean the game ends in a tie" Mavis nodded, she mentally sighed in relief, but at the same time realized she couldn't complete the main objective, "I suppose, we could end it as a tie" Natsu shrugged,

"that would mean none of our wagers matter" Mavis said,

"correct" Natsu started to ponder stroking his chin in deep thought, "I have a better game we can play" Mavis stared at him staying silent allowing him to continue, "a game of conquest" Mavis' eyes widened,

"you want to declare war?" she exclaimed, Natsu shook his head,

"of course not, now pay attention; the rules are simple, every once in a while we will select a random human in this country, my job is to convert them into demon's, your job is to ensure their humanity. The first person to convert ten people wins the game" Mavis didn't like the sound of it, to play around with human lives was against her moral code,

"let's play a different game" she tried, but Natsu shook his head,

"you chose the first game, it is my turn to choose one" Mavis' eyes narrowed obviously angry with disapproval "well, you can choose not to play the game and in that case, you will not leave this place alive" she could feel the stares of the other demons, and honestly she now had little choice, she knew she couldn't fight these odd's, it was either play the game and live, or not and die; despite having a body that didn't age she had a suspicion that the demons before her could easily destroy her. The best case scenario was to ensure every victory in each encounter so that nobody would get hurt. Mavis nodded,

"good, that's the spirit. As a gesture of good faith we will migrate to a different location and no longer step foot in the town below" Mavis was taken back not expecting him to take such action, "my wager is still present though, if I win you will become mine; but since your wager is no longer relevant, what would you like?" he asked, Mavis did not know what Natsu could offer her, however she did have an idea, or more like a contingency plan,

"if I win, you will be at my mercy" there was a brief moment of silence before Natsu burst out laughing,

"excellent! You've made this game more fun" he nodded, "I accept those conditions" there was a sudden light that bound around Natsu and Mavis. As the light dimmed Mavis slowly opened her eyes, before realizing there was a wing like mark on her hand,

"that is our contract; should you ever decide to run from your wager the mark on your hand will take control of your body and you will become a mere doll for the victor" Mavis swallowed nervously before nodding,

"I understand, but how will I know who will be part of the game?" she asked,

"do not worry, the mark on your hand will provide you with of all the information you will need" Mavis looked at the mark with interest, it didn't look like any rune she was familiar with, "now then, let us commence the start of the game!" and with another blinding light, Natsu and the other demon's disappeared along with his remaining books. Mavis looked around the now empty cave, falling to her knees she let out a breath of relief she didn't realize she was holding, she could no longer feel the demon's magical presence. Mavis didn't know whether or not she did the right thing, but she knew her life in the future will no longer be the same.

Natsu stood on top of a pillar overlooking some ruins, a smile plastered on his lips; the other demons were busy carefully stacking the remaining of their master's books. He was in deep thought,

"a guild huh..." he mumbled to himself,

"Master E.N.D" a voice called out from below,

"Mard Geer; are the preparations complete?" the demon nodded; Natsu hopped off from where he stood and walked towards the center of the mountain of books, he did a quick count and nodded in approval, not including the eight demon's that stood on the sidelines there was a total of one hundred books. He clapped his hands, a few seconds later the books were eloped in a purple light,

"release!" he called, the purple light shot up piercing through the clouds. Slowly dimming down, Natsu looked around satisfied; he was no longer standing by books, but rather a horde of demon's, they all bowed before him,

"Master E.N.D!" they called,

"Our plans have changed my demons" he said, "my brother Zeref seeks to destroy humanity, he seeks to destroy this place, this country. However I have come to like this world, the human's are intriguing and make this world far from boring. I seek to fight against Zeref, I seek to ensure humanities survival, I seek to live in a world of entertainment" Natsu turned around, gazing into the eyes of his demons, "tell me, what are your allegiances?"

"we align to our creator, to the one who watches over us, to the one who has remained by our side, we follow Master E.N.D!" Natsu nodded, and saw Mard walking towards him,

"Master, why the sudden change?" he asked in a whisper, Natsu smiled,

"the game I'm playing has sparked an interesting experiment. I want to see what human nature truly turns out to be. Is it as pure as they are depicted in stories? Or are they just as much as demons as we are" Mard didn't say anything but the thought did make him curious, Natsu continued "now that I think about it I think we should become a guild"

"a guild?" Mard questioned,

"it sounds fun doesn't it, a guild of demons that is" Natsu turned to his demons a wide grin spread across his lips, he stepped forth, "Yes! From today onward's, we shall be known as Tartaros!"

Just a quick authors note, I know that Zeref was the one who created Mard Geer and the other demons, but in this story they were all created by E.N.D.
