AN: To kick this story off, please note that there are WARNINGS that I will post now. Please be advised: Adult themes are in the works, blood, sex, drugs, foul language, and crack pairings up the wazoo. Mature audiences only, please!

Disclaimer: I do not own Fairy Tail, but there are a few OC's that I do own (seriously, like I wrote a whole 3 part story a long time ago, and I plan on using characters from that story) so please don't steal my OC's. Everything Fairy Tail related belongs to Hiro Mashima.

More notes at the bottom, but until then, please enjoy the prologue.

~Prologue~

The girl ran, faster than the average human of the age her body appeared, though her nightgown hindered her movement some. She ran as if there was physical form to the angry mob that chased her inside her mind. Well, for all she knew, there probably was, but her eyes were so blurred by the tears she could barely see what was in front of her, let alone behind her. Why shouldn't they be chasing her, though? It was obvious she had killed that woman. Maybe they hadn't noticed at the time, but they'd find out eventually.

She had never been the cause of anyone's death before - it had always been him who had done the deed, saying she was too heavenly to take a mortal's life. He felt little to no remorse for doing what needed to be done...then again, this wasn't supposed to have happened - this particular event was a complete accident.

The girl wasn't even sure how it happened. One moment, she was holding the woman's newborn baby, and, when she leaned down to place a kiss on the woman's forehead, she closed her eyes contently, looking for all the world that she was just going to sleep after the grueling task of bringing new life into the world.

The girl knew better, however. She gave the boy to his father, and, before anyone realized what had happened, she ran.

Her foot caught a root, tripping her, causing her to stumble forward. She would have fallen, but a lean arm had caught her. She didn't have to look up to know who had her - she spent enough time with him over the years to know how his arm felt wrapped around her. She turned to his body, grabbed the front of his shirt, and let out the sobs she had been holding in.

He remained quiet, for which she was thankful. She never once complained about her lifestyle, but, then again she never had to take anyone's life before. She had willingly agreed to be his servant, since it was her birthright, and he even accepted her terms of staying almost completely out of her life, showing up only when he needed her. He kept his promise, and she kept hers, for nearly a hundred years now…

But then she became friends with this small group of people, and only after did she realize their hatred for vampires. She loved them like family, so she kept her life a secret. As far as they knew she had a growth condition that kept her looking like she was still thirteen, when they really believed she was in her early twenties, like the rest of them.

She held her tongue when they decided to start a vampire hunting guild. Well, what would they have done if they had found out that she was, in fact, the servant to the king of vampires? She wanted to believe that they would put their friendship first, but then she had killed her best friend's wife right after she had given birth to a son - and then ran - she had little doubt that they'd probably kill her.

It took a long time, but she finally calmed. They sat in silence, both looking up at the treeline, her sitting sideways in his lap with her head on his shoulder. Sure, he may have been the king of the creatures she ended up swearing to protect the human race from, but he wasn't like the ruthless vampires who killed because they could. He only killed when he fed, which was very rarely anyway considering he prefered her blood.

She lost track of how long they were sitting there like that, but, eventually, she sighed and pushed herself off him.

"I can't do this anymore," she whispered, turning her back to him. He remained quiet, letting her speak her mind. "This life I have doesn't agree with the life I want. I've been lying to my friends just so I could stay with them, but it still leaked through." She clenched her fists in her lap as she felt the sadness and despair well up again. "I killed one of the people I love most. I can't go back there, not now. But I don't know if I can live knowing they hate me."

Finally, she brought her wide, tear stained eyes to look at him. He looked back at her, peaceful as always, his face a blank slate. She never knew what he was thinking, and she would have liked to know she meant more to him than a life source. She's kept him alive for nearly a hundred years, surely he treasured her a little?

"I'd rather die than be an enemy of Fairy Tail," she concluded.

The king sighed, glancing to the side. "Are you really that concerned about them taking their revenge?"

She smiled softly. Of course he'd think about that; she doubted he was ever concerned with anything other than life or death. Didn't he have someone he truly cared for? He's lived a long time, there had to be someone, at some point in his long life, that he loved so much he couldn't stand to be away from them.

"It's not about that. They were my family, and I'd like to think that, despite what I had done, they still cared for me enough to want to end my misery quickly. I took one of their own away from them...If it had been anyone else Fairy Tail would come back and drive a stake in that heart so far deep that it's own children would feel the damage as if it were their own, and any vampire would think twice before showing their face to Fairy Tail again."

She fell silent, watching his reactions. He was so good at hiding what he was thinking, but she'd spent enough time in his presence to know his little quirks. He blinked, and she knew he was thinking of ways to argue with her. He knew what she wanted from him.

"I had a sister," she continued. "I've been watching over her family, making sure they were kept safe all these years. They're just as qualified to keep you as I am."

He looked at her. "There's more to letting go of a servant than just killing you and taking one as I please."

"I know, Zeref. I just wanted you know that I'm not your last hope at living. There's still a long line of angel descendants to make sure you stay alive. Make sure they're protected, so when you wake, you can continue on like you want to." She slouched and looked away. "When you're done with me, you'll have enough energy to set your affairs in order." She sniffed as a fresh wave of tears threatened to break through. "I'm tired. Maybe I'm being selfish, but if you don't end it between us, I will. There's only one way I can do it, and I'm pretty sure you don't want to die today."

Zeref sighed, and made his way to her, which wasn't very far. He did feel pity for her, but he couldn't lie when he said he wasn't at least a little surprised this had affected her as muchas it did. She's lived a long time, she has loved and lost before...so what exactly was different with this group of Fairy Tail? He placed his hands on either side of her head, and brought her face close to his.

He paused when she closed her eyes and sighed. With a small smile, he placed his forehead against her own.

"I'll miss you," he whispered.

Her eyes snapped open and she stared at him for a beat. He had closed his eyes, but his eyebrows were furrowed in discomfort. After a moment, she gently grasped his wrists and smiled softly.

"Thank you, Zeref," she whispered in response. She understood his hesitation. After all, they had spent four hundred years together, and she'd grown to realize he was more gentle than the rest of the world believed him to be.

The vampire nodded and without any more hesitation he placed his lips against hers, allowing her one last heartfelt kiss before abruptly cutting off his magic. He took in a shaky breath as her now lifeless body fell limp in his arms.

Already he could feel his body weakening, but he knew he still had quite awhile before the eternal sleep took him again. He picked up the girl's body, and started the first step in putting all affairs in order. He needed to find Mavis' sister, first and foremost, and he hoped the humans of Fairy Tail would tell him where to begin searching.

AN: Hey guys! Long time no see, I know...I suck. -Sad face- For those of you who have faved/followed me, you're probably expecting an update on my other stories. The truth is, I've run out of juice on them. I've tried to continue, but I just stare blankly at what I've written so far, and I can't come up with anything (a couple of them weren't even being worked on religiously anyway, so it had been warned that they weren't going to be updated often anyway). So, here's my official apology.

Now, then, notes on this story. So, if anyone has visited my page, you'd know this one has been a long time in the making. This is my first official LucyXZeref story. I've got more in the works, but I'm going to start with this one to ease everyone into my Zercy obsession. There aren't very many stories out there, but I plan to change that. I've got a few one-shots to put out, so, if you like this pairing, keep an eye out for those.

As I stated before, there are plenty of mature themes (it's rated the way it's rated for a reason, ya know!), so read at your own discretion.

Now then, since that's all finished, please review/fave/follow, and I'll see you next time. Thanks for taking the time to read.
