Disclaimer: I am not the owner of Fairy Tail or Once Upon a Time

WARNING: Contains spoilers for Alvarez Empire arc of Fairy Tail, and Season 2 of OUAT.

This story takes place during season 2 of Once Upon a Time, with a few alterations. Due to the focus on Fairy Tail for this story, Belle did not get shoved over the town line and did not lose her memories. Beyond that, the majority of Once Upon a Time has remained unchanged up to that point.

Before the Dark Curse, in the kingdom of Fiore, residing within the same realm as Arendelle and Misthaven (The Enchanted Forest)

Zeref was smiling at his achievement, deep within the guild of Fairy Tail. They had been at war for years, his Spriggan Twelve battling against the most powerful mages the guild possessed. In the end, he always knew that this would be the outcome, that he would finally have access to Fairy Heart.

If they understood the reason behind his actions, perhaps Fairy Tail would not have fought so hard. He simply sought out peace in his life, a way to end his suffering. This world was constantly rejecting him, something Zeref had learned will never change. Thus, he had few options left to turn to. He could end his own life, but that was an impossibility. There was only one weapon capable of destroying an immortal being like him, and unfortunately, it was far beyond his grasp, hidden deep within a realm with even stranger views of magic than there were here. He had tried, once, to lay claim to it, only to lose interest when he discovered the dangers that existed within that land.

There was the second option, the option of the neo eclipse gate he had in mind. Essentially, it would reset time and allow him to return to his former life, but for some reason, the idea was sounding less appealing every second. He did not want to relive the war, nor did he want to have to watch his family perish again if he found himself incapable of protecting them this time. He had lived with this curse for long enough, he had no intention of seeing any more death around him.

This was why Zeref was now settling for his third option, one which would also require Fairy Heart simply due to the sheer amount of magic required. After all of his years of studying magic, of searching for a way out of his curse, he had finally cracked the code to creating a portal between realms, and not just any portal. He had discovered how to make one between a magical realm, and one without magic, a place where he could finally be free of his curse. After all, without magic, even if his body was cursed, it could do nothing to him. No more death, and no more immortality. He would finally age and pass on from this world, just as he had been desiring for so long.

Staring up at the crystal in front of him, Zeref felt himself smiling slightly. It was time to move on from this place, and leave his brother behind. After all, without magic, END would simply not be able to live on, nor would his other creations manage to survive. You see, his spell would not just take himself to this new realm, it was also going to take all of Magnolia with him. It functioned much like an Anima, draining away those with magical ability into a new realm, though it avoided stealing away the magic itself.

He reached out tentatively towards the girl imprisoned within the crystal before him, ready and waiting for Eileen to activate Fairy Heart. It was the last thing he needed, all that he was waiting on was for her to finish dealing with the guild members and join him. Fighting was still going on, scattered throughout the city amongst his army and the members of various guilds, but he knew that he would be victorious. At least, that was what he thought when a massive crack began to appear in the crystal before him, stunning him as it began to break and shatter apart.

"Fairy Glitter!" he heard, the sound of a girl yelling behind him. Zeref turned back, seeing a wave of golden magic burst from her, attacking an unseen individual in front of her. The girl attacking had brown hair, long and curly hanging over her shoulders, and was wearing little more than a bra and pants. Before her, Zeref knew exactly who was present. Mavis' illusion body existed at that spot, and was currently under attack by one of her own guild members.

"Stop! You will ruin everything!" Zeref shouted, prepared to attack the girl, but it was already too late. A massive shattering sound was heard as crystal scattered everywhere, freeing Mavis' body from her eternal prison. Zeref watched as the girl he had loved over the last century fell out from the lacrima, her body weak and frail, but still alive. He could not believe it, not after all of these years. She had been dead, yet immortal, thus she still survived in some small form. That was how he had always thought of her curse, the one that was ultimately his own fault.

Mavis slowly got up, blinking a few times at the world around her. "Cana, thank you for…." she began, before her cheeks began to redden, glancing down at herself. Mavis shrieked, realizing that she was wearing no clothes, a result of her imprisonment in the crystal. Before Zeref could say anything, her own magic created the illusion of clothes on her body, a light pink dress seeming to cover her immediately.

"Mavis….you're still alive. Please, I need to ask you for something." Zeref stated, staring over at the girl whose gaze narrowed at him. She had every right to hate him, after everything he had done. He would tolerate that hatred, so long as he knew she was alive and well. After all, it was no different from how the rest of the world saw him, something he had grown used to over his long life.

"Zeref…you've attacked my guild and threatened the lives of my friends. Do you truly think I am willing to aid you in any way?" Mavis asked, standing and doing her best to look strong before him. Zeref gazed at her calmly, aware that she would feel this way until she heard his offer.

His gaze flickered slightly to Cana, the mage still present before them. She mattered little in the end, so he supposed it would do no harm if she overheard this conversation. "We are still cursed, Mavis, that is something that shall never change. However, I have a solution, one which you might be inclined to take." Zeref stated, watching the girl's face grow sad, thoughtfully gazing at her bare feet on the ground.

"I no longer have the intention of using the Neo Eclipse Gate, Mavis, instead, I wish to open a portal. Using Fairy Heart, I shall take us to a world where magic does not exist, where even with our curse, we will no longer be forced to watch the lives around us fade away." Zeref argued.

Mavis gazed up at him, a small amount of hope in her eyes as she struggled with her decision. "Zeref….I can't….but I don't….I don't know what to do!" she stated at last, tears in her eyes. "Even after all of this time…..part of me still wants to trust you, to love you with all of my heart. Yet I know, after everything you've done, that I won't be able to let go of my hate that easily." she stated.

Zeref held a hand out towards her, an offering for her to either take or reject his plan. "I understand, and I would expect no less from you. I am not requesting that you stay by my side, Mavis, though I would prefer it if you did. My only wish is to borrow your power, so we can be freed from our curse." Zeref stated.

"What the hell is he talking about? First, what is going on?" Cana demanded, clearly confused by everything going on. Fairy Tail had fought hard, and they still had no idea of what they were truly protecting. After a few more moments of hesitation, Mavis slowly began to nod, her hand reaching out towards Zeref and clasping it within her own.

"Very well, I will aid you. I once promised to find a way to end your curse, and this is my way of fulfilling that promise. Please, find light in your life, and let love into your heart once more." Mavis insisted, while Zeref gave her a sad smile, nodding as he felt the magic power within her open up, increasing tremendously. She was channeling it through him, allowing him access to unlimited magical power as he focused on his spell, opening a portal unlike any this continent had ever seen.

Somewhere a ways away from this place, an evil queen was also casting a spell of a similar nature. Little did the people of Fiore know, Zeref had actually saved them from a far worse fate then simply moving to a new realm. As the massive portal opened in the sky, swirling with dark black streaks of lightning running within it, the wizards believed that they had failed, that everything was over and that Fairy Tail had fallen. Their true adventure had only just begun, as they were all scattered across the globe, brought to the real world where magic was nothing but a dream, and wizards were nothing more than a fairy tale.

Arriving in the new realm was hard for everyone, especially once they realized that none of their allies were close by in many cases. Lucy felt dazed, surprised that she was still alive as she sat up, glancing at the world around her after the portal had hit. She had thought that it was what Zeref was using to change the past, but apparently, something else had happened.

She was on a busy street, in the middle of New York where people were giving her strange looks. Glancing around, Lucy realized that while her clothes weren't too out of place, they were a bit revealing compared to what everyone else was wearing. Her short skirt and heart creuz shirt definitely gave her an appearance that stood out amongst people wearing t-shirts and jeans, walking down the sidewalk and passing her as she sat on the ground.

"Where is everyone? Where am I?" Lucy asked, confused as she gaze around. Someone had finally stopped walking near her, and their eyes were wide, pointing at someone on the ground by her side. Lucy frowned, following their gaze before her own face paled, her body growing cold. Sitting on the ground next to her, was Natsu, with a blue cat sitting on top of him. Happy seemed to be concerned about his friend, but strangely, the cat didn't seem to have anything to say. He was actually meowing, like a normal cat! Something was wrong here, and Lucy had no idea what it was.

Slowly, she moved closer to them, touching Natsu's shoulder to try and wake him up. He didn't move much, but she was used to him being a heavy sleeper. Preparing herself for him to punch her, Lucy got a bit more aggressive, shoving him hard. "Come on, Natsu, get up!" she insisted, before seeing just how still he was, how his chest wasn't even moving as he breathed. Something was wrong with Natsu, if she didn't know how unstoppable he was, she would have said that he was dead.

"No…" she whispered, still not accepting this fact. She pressed her hands to his chest, rolling him over on to her lap. "Please, you can't be….Natsu, I need you!" Lucy begged, pleading with her friend as tears began to roll down her cheeks. Happy seemed to have the saddest look on his face too, standing on four legs as he moved closer to them, rubbing against Natsu with his paw. Glancing at Happy, she realized just what the issue must have been. This place was another realm, just like Edolas had been. It had no magic, instead of just limited magic, so Happy wasn't even able to talk or fly like he could in Edolas. As far as Natsu went…well, none of them understood what was wrong with him. People continued to gather around them as sirens began to sound, while Lucy continued to wail, clutching her dear friend as close to herself as possible, wishing that this was all a dream and that he would just come back to her somehow. Even so, happy endings don't come quite that easily in the real world, something that many people were beginning to learn in a town known as Storybrooke that had just appeared moments ago in this realm.

Other guild members were scattered across the globe as well, finding themselves in odd places around the country. Juvia and Gray found themselves waking up in the same city, since they had been bound together by Invel's Ice Lock when the portal opened and brought them here. Elsewhere, Levy and Gajeel found themselves dazed and confused, observing this strange world and wondering just what to do next. Even in this new world, they were still Fairy Tail wizards, and they understood how to adapt to survive. Even if it took time, they would find their way back to each other, and survive this new realm. That was what they all felt deep in their hearts, even in the hearts of those such as Sting and Rogue who were not part of the guild, now unable to talk to their closest friends who had seemed to revert into the forms of normal cats in this realm.

Wendy and Erza were side by side in this realm, deciding to act as sisters who had just survived a terrible accident. They had severe wounds from their battle with Eileen, so their cover story was quite believable to anyone who questioned them. Gajeel and Levy stayed away from others, due to Gajeel's personality and Levy's insistence that it would be better to learn about this world first before deciding who they would be in it. Sting and Rogue stuck together as always, quickly finding a job at a local fast food restaurant so they could somehow manage to get by here. Without any records for themselves, it was quite challenging to even get a job like that, making them realize just how different this world was that they had arrived in.

Mavis and Zeref were in the same spot together as well, standing on the street in Boston as they came out of the realm of magic they once lived in. Zeref was still dressed in his usual black robe with his white sash, but Mavis…well, her clothes had only been an illusion, after all. She shrieked and tried covering herself up immediately, realizing that this was going to be a problem in this new world.

Zeref closed his eyes, smiling slightly as he pulled off the sash he always wore. "It might not be much, however, I do believe it is preferable to your current state." Zeref told her, handing it over to her. Mavis blushed furiously, snatching it away from him and hurriedly wrapping it around her. It didn't look the greatest, a lot like a toga that didn't even fit her, but it was better than nothing. Zeref took in a deep breath, his gaze opened as he glanced up at the sky, feeling at peace for the first time in his life. People were all around him, walking down the street they were standing in and staring at them in confusion. He could care less about how this world viewed him, all he wanted was for it to survive his presence here. So far, it seemed to be working. No one was dying nearby him, and he could not feel even a hint of ethernano in the air around him. Magic was nonexistent, and he was finally free from his curse.

"Zeref…what are you going to do now?" Mavis asked, turning towards him with a frown on her face. It was a good question, since he had spent so long aiming for this goal. He had only ever wished to be freed from his suffering, he had never truly imagined that it would occur in a way that left him alive.

"Perhaps take some time to discover this realm and make it my home. I did well before as the ruler of an empire, perhaps I could take a similar position in this realm." he stated, knowing that he had found that task amusing in many ways. Viewing people as pawns, while not preferable, was a way to pass the time as he waited for the death that would now finally be coming for him. Just one more century of life, likely less, and his own old age would be his end.

Mavis grabbed his hand, glancing up at him nervously. "I…I want to find the others. I know that I can't do it on my own, either…." she mumbled, glancing down at the ground as she pulled back, her hands clasped together in front of her legs as she avoided Zeref's gaze nervously.

The former black wizard smiled over at her, gently touching her shoulder. It would take time to get used to the idea that contact was not going to lead to death, but with Mavis, he felt confident he could learn that quickly. "If you wish for me to aid you, I am more than willing to help. After all, I do owe you much, after everything you have done for me, Mavis." he stated, watching as she squealed in joy, surprising him when she wrapped her arms around him in a sudden hug.

"Thank you! You are the best, I promise, we're going to have the greatest adventure ever!" she shouted, skipping off down the street. Zeref smiled, shaking his head as he began to follow after her, ignoring the strange looks they got from others as they passed by. Sure, they seemed strange now, but in a few years, they would all blend in with this world. No one would ever even realize that Earth had just gained over a hundred new inhabitants within the planet, even if they all did have a few quirks that made them stand out among others.

So, I just saw Fairy Tail Dragon Cry and had to write something involving Fairy Tail! This was the result, I hope you enjoy a crossover between two of my favorite shows!

For my stories at the moment, I am working on quite a few so here is how updates will work. The two stories in progress with the most reviews will receive weekly updates! All others will be updated monthly, so if you wish to see more chapters coming out quickly, leave a review to push this story up in the ranks. Currently, second place has six reviews, so it won't take much to get this one up to weekly updates.
