Summary: In a world where Vampires openly co-exist alongside Humans, the two sides live in relative peaceful harmony, respecting the rules and regulations agreed upon by both sides.

Regina Mills, a Vampire who has seen much in her hundred years on this earth, now prefers the quiet and peaceful silence of solitude. She keeps to herself and doesn't make waves, working diligently to blend in with the Humans. But, even though she enjoyed the simplicity of her solitary life, she always felt like something was missing. An uncharacteristic decision one night caused everything to change suddenly, when she saw the beautiful blonde vampire hunter for the first time.

Emma Swan, a vampire hunter who was recently promoted to Boston after bouncing from city to city for work, tries to acclimate to the New England weather. She didn't know what it was about the old city that called to her, but perhaps it had something to do with the beautiful woman with the stunning brown eyes, that she crashed into one night in front of the Boston Public Library.

A/N: HI! Welcome to my new fic! There have been a few fics that I've written so far that feels like I poured my blood, sweat and tears into, and this one is one of them. I am so incredibly proud of how this turned out and so so so incredibly exited for you to read it! I really really hope you enjoy it as much as I enjoyed writing it! As always, there's a few bits of housekeeping that I want to discuss before we take a bite of this story.

First, let's talk trigger warnings. Firstly, this is a Vampire story, and it goes without saying that there will be a LOT of mentions of blood as well as drinking blood. That's the nature of vampires. The biggest trigger warning is for self harm as well as suicidal attempts and discussions. None of the attempts result in death and the self harm does have a purpose in the story. There is also a major character death, but I PROMISE it is only temporary. I can't ever REALLLY kill them. There is a happy ending, as always! There is also a bit of violence as well as a brief discussion of a past non-con incident as well as a discussion of torture. All warnings will be marked in the beginning of each chapter so you know it's coming, that I promise you!

Second, I want to thank my amazing artist, Dragoon23 for creating the amazing art for this story! Please go check it out on AO3

And, as always I do not own Once Upon a Time, nor any characters, locations or events associated with it. The story belongs to me, but the world belongs to them.

And now, without further ado, I proudly and excitedly present "Only You"

Chapter 1

The air was crisp as Emma Swan entered the cemetery, the light of the full moon illuminating the headstones while she slowly walked through the rows and rows of graves. She kicked a stray rock, scanning the surroundings, searching for signs of anything out of the ordinary. She had only been in Boston for a few days, having recently been transferred to the Boston office from Tallahassee a week prior, and tonight was her first official night working in the new city. She had packed up her few possessions, jumped into her car, and drove north as soon as she heard about the promotion, leaving the warm sunshine behind.

What she didn't expect was how cold it would be in Boston at night. She pulled her jacket tighter around her body, shivering slightly before she continued to walk through the cemetery, a wooden stake hidden in the sleeve of her right arm, knives dipped in holy water attached to her belt hidden under her shirt. Emma Swan was a vampire hunter, and a pretty good one at that. Her hard work and dedication to the cause allowed her to quickly work her way up the totem pole, and it helped her to be transferred to the regional office of The Agency. She had been looking forward to moving to Boston until she felt the cold air on her face for the first time. Even though it was much colder than Tallahassee, there was something intriguing about the old city, and she was excited to finally get the chance to explore and see the sights. But for now, she was on cemetery duty for the night.

In the early 90s, the high counsel of Vampires decided they were tired of living in secret, and after three hundred years of hiding away from the world, they made their presence known and demanded rights as citizens, which did not go over well at first. Humans saw them as a threat, not only to their lives but to their status in society. Violence ensued, a war was fought and lives were lost. In the end, Vampires won and were able to begin living in society, agreeing to certain rules and regulations, the largest and most enforced was known as the blood principle. Vampires are strictly forbidden to feed off of Humans without their permissions.

Because of this, Vampires began developing a substitute for human blood. Eventually, they came up with a combination of animal blood mixed with just a small amount of human blood, allowing them to continue to live without hunting Humans, thus allowing them to remain a part of society. Most Vampires choose to live a quiet existence, happily consuming this new blend of blood. In return for this peaceful existence, the Humans agreed not to hunt or harm Vampires, unless provoked. That was when The Agency was developed. The Agency was a country-wide organization, and its only purpose was to protect Humans from rogue Vampires, those who still wish to feed from Humans in a violent manner. The emergence of Vampires into society suddenly solved thousands of missing persons cases for hundreds of years as the missing people came forward to explain they had been living as Vampires the whole time. Families received the closure they desperately needed and were able to be reunited with missing members. After all the fighting ended, the revolution turned out to have a positive end.

Emma had been young when the revolution had taken place, and as a result, she didn't remember much about it. The only change that really occurred to Emma's young life was the knowledge to be extra vigilant when walking at night, and to avoid being outside after sunset, even in their own backyard, if at all possible. Her parents insisted she be home before dark and would only allow her to visit her friend's homes during the day and only after they had seen every member of the household in the sunlight. But Emma thought nothing of these strange rules and grew up not knowing any other way. Until one day, when her entire life was turned upside down.

When she was fourteen years old, she lost her mother to a Vampire attack. Her mother found herself stranded on the side of a mostly deserted road with a flat tire after sundown. She tried calling a tow truck to help her but, as her bad luck continued, she discovered a lack of cell phone signal. She quickly got to work on changing the flat but was only able to remove the damaged tire before she was attacked. Twenty-four hours later, once her family was able to officially report her as a missing person, the police found her car on the side of the road. Nothing had been taken from the car, and all that was left was her car, still on the jack, and a small puddle of blood next to the removed tire on the ground. From that moment on, Emma vowed she would enlist in The Agency once she was old enough. She would avenge her mother's death in any way she could. So, on the day of her eighteenth birthday, Emma enlisted and started her training the next day. After receiving her training, she bounced around from city to city for years before receiving her assignment in Tallahassee. She liked Florida, but there was always something missing when she was there, which was why she was excited to be relocated. To start over. To find what was missing in her life.

Emma sighed as she continued to scan the old cemetery, searching for signs of new graves or any evidence that the earth had been recently disturbed. Most of the time, Vampires will bury the bodies of those they are attempting to change during the day to protect them from the sun while they endure the transformation. Not all Humans survive the change, but those that do will emerge from their shallow graves shortly after sunset, hopefully to their waiting Sires. Only those very special and very precious to the Sire are invited to endure the change in the Sire's bed with them, so most Fledgling Vampires begin their Vampiric life underground. As an experienced hunter, Emma knew cemeteries were the preferred burial sight for Fledgling Vampires, because no one would suspect foul play when they see a fresh grave in a cemetery.

Just as expected, Emma caught movement under an old tree out of the corner of her eye. The ground was moving under what appeared to be a fresh grave. Sloppy work, she thought as she casually walked toward the moving ground, making it over to the unmarked grave just in time to see a confused head popping out of the ground. If the Vampire who had turned this Human cared about their Fledgling, they would be close by, ready to collect their Fledgling. Maybe I'll see some real action tonight after all, she thought to herself as she approached the grave. Unless the Sire abandons them. Even though it was technically against the treaty with the Vampires to kill innocent Vampires, it was always the policy of The Agency to eliminate the threat at the source before the threat was present. A moment later, a hand broke through the soil, frantically waving around for someone or something to hold onto. Emma reached down and connected with the poor soul, gently pulling to help them up.


Regina Mills began to stir in her bed just as the sun set behind the horizon. After almost a hundred years of living as a Vampire, her body had learned to react to the exact moment of sunset, waking her up as soon as it was safe for her to emerge. She stretched and checked the clock on her nightstand, contemplating going back to sleep for a little longer. Fuck, she thought as she rolled over, suddenly remembering that she had a new Fledgling buried in the cemetery from the previous night. She wasn't particularly attached to the young man she had attempted to change, but she felt obligated to at least retrieve him and ensure he had his first feed before sending him on his way. That was, if he even survived the change at all.

She sighed as she forced herself out of bed, instantly regretting her last-minute decision to change someone the previous night. She hadn't attempted to create another Vampire for decades, and she didn't know what suddenly made her decide to create one last night. It wasn't that the young man was particularly memorable. She didn't even remember his name. Shaking off her confusion, she began to prepare for her night out, regretting her decision the entire time. She eventually left her tiny studio apartment and made her way toward the cemetery where she had buried her Fledgling the night before.

She kept her head down as she approached the cemetery, attempting to keep a low profile as she pushed the old gates open, the hinges squeaking slightly as they moved. She kept to the shadows as much as possible as she made her way over to the tree she had left her Fledgling buried under the night before.

That's when she saw her. The vampire hunter.

Regina had become proficient in spotting a vampire hunter from miles away. And the blonde woman standing under the tree was definitely one. Fresh meat, she thought to herself as she watched the new hunter from a safe distance. Although she had never seen the blonde woman before, there was something about her that was intriguing, almost familiar. She watched as the blonde hunter reached down to grab her Fledgling's waving hand, helping to pull him out of the ground. As soon as his chest was freed from the ground, she effortlessly drove a wooden stake straight through his heart, turning his body into dust instantly. She was good, a seasoned hunter by the looks of it, based on the ease in which she drove the stake into his chest, as if this wasn't the first Vampire she had killed.

Regina shrugged it off, silently thanking the hunter for taking the Fledgling off her hands. She wasn't in the mood to deal with a new Vampire tonight, and if she remembered correctly, he was a bit of a clinger anyway. After nearly three decades of solitude, she wasn't about to start babysitting a baby Vampire now. She turned on her heels and made her way out of the cemetery, turning around once more to make sure no one was watching as she slipped through the gate she had entered not long ago. Her eyes fell upon the blonde hunter through the wrought iron fence that surrounded the cemetery, watching as the hunter appeared to wander aimlessly through the old gravestones. Regina knew better. She knew the hunter was searching for more newly risen Fledglings. As she stared at the woman for a few more moments, she couldn't help but notice how the light from the full moon fell upon her long blonde hair in such a way that she almost looked like she was glowing. She certainly was an incredibly beautiful woman.

Once the beautiful hunter moved out of her sight, she began to walk down the street, her head hanging low in an attempt to keep a low profile. She made her way down the quiet streets, reaching her destination just as a flurry of snow began to fall from the sky. The snow is coming early this year, she thought to herself as she reached for the door handle in front of her. It doesn't usually start snowing until after Halloween.

She pulled the heavy metal door of The Blood Moon open, rushing in and pulling the door closed behind her in an effort to keep the cold air outside. The Blood Moon was a well known Vampire bar in Boston, catering to both Vampires and Humans alike. The Blood Moon allowed for a safe place for Vampires and Humans to mingle together, giving Vampires an opportunity to find willing Humans that will allow them to feed off them. Regina hated that aspect of the place. She found the ways some Humans would practically throw themselves at any Vampire that would give them the time of day, with the slightest hopes of becoming one of the immortals themselves, to be disgusting and disrespectful. They only cared about one thing, and it wasn't the Vampire they were approaching.

As soon as Regina walked in, she was approached by a young boy, offering her a drink from his neck, which she politely declined before he could even finish his sentence. She was even less in the mood to babysit hopeful Humans. When they were that young, they were only seeking the hopes of immortality that being a Vampire offers. They didn't care about her, only what she could do for them. Why can't a mature young lady approach me for once? I can't stand these children anymore, she thought to herself as she took her usual seat at the bar.

"Hey, Regina, what can I getcha?" the familiar bartender asked as he approached her from behind the bar.

"Do you have any AB+ on tap, Graham?" she asked.

"Fresh out, Regina, sorry. It's been a slow month for AB. I have some vegan crap for those hipster Vamps. They swear it tastes just like AB," Graham said, rolling his eyes. "I can't bring myself to try it though."

"I think I'll pass on that as well," Regina said, rolling her eyes. "B+?"

"That I can do." Graham smiled, his fangs showing as he filled a pint glass with the warm blood from the tap, placing the drink in front of Regina before disappearing down the bar to help other customers. She took a sip of the warm thick liquid, her thirst instantly quenched as she looked around at the crowd that had begun to form. She recognized the regular Vampires who frequented the bar, looking for their next meal, preying on the young and pretty Humans, the ones looking for immortality. Those were the ones who usually didn't survive the change; that is, if the Vampire chooses to give them their dying wish. It's common knowledge that the younger the body, the harder the change is, decreasing the likelihood of survival. But the promise of immortality and eternal youth was always too addictive.

Regina was an Elder Vampire, living for over a hundred years. She was changed in the early 1920s at the age of thirty-five and abandoned by her Sire after a few weeks of being together. When Vampires revealed themselves years ago, Regina stayed in the shadows. She didn't want any trouble; she just wanted a quiet and peaceful existence, free of violence and drama. She genuinely kept to herself most of the time, except when she made her way to The Blood Moon to spend time with her only friend, Graham, who was the bartender and owner of the establishment. After decades of being alone, she had given up the idea of finding a mate and accepted the loneliness she felt every morning when she was alone in bed before she fell asleep.

Regina drank her meal slowly, in no rush to get back home, but still not looking to make idle chit-chat with anyone, Vampire or Human alike.

"Hey there, pretty lady. Let me see those fangs," a young voice said behind her, startling Regina slightly.

"You have got to be kidding me." Regina rolled her eyes, looking over her shoulder at the young boy behind her. He was practically a fetus. "And that is my cue to leave," Regina said, swallowing the last of her meal.

"Aww come on, let me buy you some nice O-," the kid said, trying to convince Regina to stay.

"Clearly, you've never done this before. You never offer O- to a Vampire. O- is reserved for Fledgling Vampires on their first feed, or Vampires who are sick or hurt." Regina laughed as the boy's face turned bright red from embarrassment.

"Graham, may I have a second, to go, please?" Regina asked, passing an empty glass bottle to the bartender, now completely ignoring the child behind her. Graham quickly filled the bottle with B+ blood, sealing it tight before passing it back to Regina. She offered a few bills to Graham to pay for her second order, but he refused.

"This one is on the house," Graham answered, pointing to the child still hovering behind Regina, desperate for her attention. She gracefully climbed off the bar stool and made her way toward the door, completely ignoring the child who started to follow her toward the door.

"It's considered rude for a non-Vampire to approach an Elder Vampire without permission. Learn more about Vampire culture if you wish to become a part of it," Regina said without turning around, walking out of the bar and back into the late autumn night. She walked home slowly, wishing she could still feel the coolness of a crispy autumn night. However, due to the low body temperature of Vampires, the cold doesn't affect her anymore. At least she could still smell that unique scent of autumn, which was slowly being replaced by the distinct smell of ice and snow that winter brings.

She eventually made it back to her small apartment, locking the door behind her once she was inside. At least I don't have to deal with anyone else for the rest of the night, she thought to herself as she made her way to the kitchen, pouring a small amount of the blood she had brought home from The Blood Moon into a small saucepan, placing the rest in the refrigerator for another time. She turned on the stove and began stirring the blood she was slowly warming to ensure it didn't burn. Once her snack was warm enough, she poured it into a mug, using a plastic spatula to make sure every single drop of blood made it into the mug. She settled into bed with her cup of warm blood and a dusty old paperback book with a missing cover and frayed pages from decades of readings. That's where she spent the remainder of the night, in bed alone with a mug of warm blood and a good book, eventually turning in for the day when she felt the sunrise approaching.


The sun was already starting to rise as Emma unlocked the door to her small apartment. It had been a successful evening after all. She killed three Fledglings and even went head-to-head with one of the Fledgling's Sires, sending them to their eternal sleep along with the rest of them. She made a beeline to the fridge the moment she locked the door behind her, pulling out a beer. She knew it was probably too late to be drinking, but she didn't care. She had a good night and wanted to reward herself for a job well done.

She cracked open the bottle, tossing the cap into the sink as she took a long sip of the cold liquid. She carefully placed the beer on the counter before she started emptying her pockets, tossing her stakes in the small cardboard box she kept on her kitchen counter, placing her collection of knives neatly on top of the pile. She started walking away, only to stop and return to the counter, grabbing a bottle of holy water from the cabinet to remind herself to dip her knives in the liquid before she went out hunting the following night, making a mental note to restock her supply the next time she was in The Agency headquarters building. As much as she didn't mind working for The Agency, she really hated going to the headquarters buildings. No matter what city she was in, they were always too big and uninviting and she avoided going there as much as possible.

She slowly made her way to the living room, taking another swig of beer before flopping onto her couch, an exhausted sigh escaping her lips as she settled into the slightly lumpy cushions. Taking yet another swig of beer, she flipped on the TV, the sounds of an infomercial kept her company as she turned on her computer, attempting to fill out as much of her nightly reports as she could before she passed out from exhaustion. A few minutes into filling out the first report, her computer chimed, indicating a new work email. She had a bad feeling about the email; it was never a good sign when work was emailing her so early in the morning.

"You have GOT to be kidding me." She growled as her eyes scanned the email in front of her, indicating they were requiring her to be in the office at ten o'clock for a mandatory staff meeting. "Don't they understand that hunters work at night? It's inhumane to expect a hunter to be anywhere at 10am." She rolled her eyes as she chugged most of the beer she had left in her bottle. Sighing, she abandoned what was left of her celebratory drink on the table next to her computer containing her unfinished reports and she made her way to the shower. She took the fastest shower she could manage while still making sure to completely wash and condition her long blonde hair before crawling into bed to sleep for a few hours. Emma was definitely going to be late for the meeting that morning, but she really didn't care.
