A/N – Hey guys! To those who've read my previous story, La Trahison, Semper Vivens is kind of a sister story, and some of the minor characters in that are major characters in this. No worries if you haven't read that, though; it's not quite essential to the plotline.

Warnings –

This story is a tragedy. I will make no attempts to hide that it has no happy ending. If you've read La Trahison, you'll know what happens to them.

This story is very different from my other one. Vivienne is nothing like Rochelle. As a matter of fact, I admit that my OC is kind of a bitch in the beginning. That's how I want it to be.

This IS an OC story. There are people who think that all OCs are Mary Sues or self-inserts. If you're one of those people then I won't ask you not to read this story, but I will ask you not to try to share your opinions with me and expect me to agree. I don't need that kind of negativity in my life. That being said, as long as you're not prejudiced against my story without reading it, I do appreciate and welcome constructive criticism. I've deleted entire chapters and changed plotlines because I've been inspired by reviewer's suggestions and remarks.

There are claims that the Rosiers and the Blacks are related. I checked this through, and that would make Regulus and Vivienne second or third cousins, though only by marriage. They don't share any blood. If you still consider this incest, then I'm sorry. In my opinion it helps capture the reality of pureblood society. They're all somehow related to each other.

Although this is mainly Regulus/OC, it contains sub-plots of Rabastan/OC and Narcissa/Lucius

That's about it. Enjoy!

Chapter 1

Vivienne Rosier would have given anything to be on the Slytherin Quidditch team.

She lay on her stomach on the grass, chin resting on elbows as she watched the figures in green zoom around the Quidditch pitch. Mondays and Thursdays were Slytherin's allotted practice times and no matter how much homework Vivienne had, she made it a point to come down and watch from her spot on the lawns. The spot was a good distance away; she liked it best because it afforded her a good view without attracting any attention to herself.

There was something about the freedom of the wind running through her hair that Vivienne adored. She loved how nothing mattered but the smoothness of the wood under her legs and the wind roaring in her ears.

Vivienne blew a strand of hair out of her face and watched skeptically as Lucius Malfoy swerved into a dive that he couldn't possibly pull out of. Show-off, Vivienne thought, as the blonde haired boy crashed, the edge of his broom hitting the ground before he did. Luckily, another team member flew down to help him out and he seemed uninjured. Vivienne rolled her eyes. Stupid and reckless feats were usually left to the Gryffindors. Slytherins did what they had to do to win, that was all. Clearly Malfoy was yet to understand that.

"Vivienne! Viv! You'll never believe what we have to tell you!" a voice called out. Vivienne turned and saw two girls heading towards her. Narcissa Black and Freya Hazelwood were her closest friends, and they'd all bonded in their very first year at Hogwarts. The three girls shared both a dorm room and a love for gossip. Vivienne sat up as they finally reached her.

"What's the news?" she asked, watching them both catch their breath. Narcissa was a little red in the face, but Freya looked almost gleeful. "Merlin, you two are out of shape. Did you just run all the way from the dungeons?"

Freya smiled, plopping down on the grass beside her friend. "Well, we just couldn't wait to find you. Go on, Cissy, tell her. You're practically blushing."

"It's the heat," Narcissa insisted, but there was more to the unusual flush of her pale skin than just the afternoon sun. She pushed her blonde hair back from her face and looked up at Vivienne sheepishly. "I just received a letter from my Mum. I'm to be betrothed."

Vivienne's eyes widened, and she stared at her friend in surprise. "No!"

"Well, don't stop there, tell her who it is!" Freya pressed eagerly.

Narcissa's face turned an even deeper shade of red. She looked as though she was trying not to show her pleasure, but the corner of her mouth was turned up. It was clear that whoever this man was, she was very happy with the idea of him. "Lucius Malfoy."

Vivienne raised an eyebrow. "The one who thinks he can pull off a Wronski Feint when he can barely fly? I think you could do better, Cissy. He's a bit stuck up."

Narcissa shrugged, trying not to look offended. Vivienne was known for her brutal honesty, and both she and Freya had learned to handle it. Still, it hurt slightly that her friend didn't seem to think as highly of her betrothed as she did. Freya noticed Narcissa's uncomfortable expression and attempted to lighten the mood.

"Oh, sod off Viv," Freya replied simply. "You're just jealous that she found a husband before you. I think he's gorgeous, Narcissa. You're going to have the most adorable little babies!"

"As long as they don't inherit his flying skills," Vivienne retorted, smiling at Freya. The awkwardness faded away and the two girls smirked at each other, ready to start their usual banter. "But I'm afraid that pitiful flying seems to be the dominant gene nowadays."

"Well, I think Lucius is a wonderful match for Narcissa. He's quite the gentleman."

"I think he's an arrogant prick."

Narcissa rolled her eyes. The conversation wasn't even about Lucius anymore, it was that Freya and Vivienne refused to agree about anything. Vivienne's brutal honesty and Freya's willingness to say anything to make people happy, often collided. "It doesn't matter what either of you think," Narcissa pointed out. "Because I'm the one that's marrying him. And I think he's handsome."

"Fine," Vivienne shrugged, giving in. "Hopefully you can get him to cut that hair once you're married. Who gave him the idea that a ponytail would look good, I don't know."

Narcissa smiled, turning to look at the Quidditch pitch. Lucius was up in the air, yelling at one of his teammates. There was something about his confident swagger and icy blue eyes that entranced her. She knew that she was lucky to get a catch like him, especially considering the scandal her family had gone through when Sirius Black eloped over the summer. Narcissa was determined to make her parents proud. If Bellatrix could be betrothed to a rich man from an ancient pureblood line, then so could she.

"Daydreaming about him already, Cissy?" Vivienne teased, as she noticed her friend's eyes linger on her betrothed. "You're not going to be married quite yet, we still have over two years left at Hogwarts. You'll have to be content ogling him while he's playing Quidditch."

Freya raised an eyebrow at Vivienne playfully. "As if you don't already do that. To be honest, all this nonsense about you being passionate about Quidditch doesn't convince me. I've never once seen you on a broom. I think you just come down here twice a week to stare at the boys."

Vivienne laughed. She had to admit, Freya wasn't completely off. Slytherin's handsome boys did give her a little incentive to come down here whenever there was Quidditch practice, although it wasn't the only reason. "Oh, really? Do tell, which of our stunning team members do you think has caught my eye, Freya?"

"Oh, I don't know. There are so many to choose from. I would have to say that the best looking one is probably..."

"Lucius," Narcissa filled in. Vivienne raised an eyebrow at her friend.

"Really, Cissy? I understand that you're betrothed to him, but he is by no means the most handsome boy up there," Vivienne replied.

Narcissa shrugged. "I think he is," she mumbled, but Freya had already made her decision.

"Evan Rosier," Freya decided, shooting Vivienne a sneaky look. Her friend's mouth dropped open in horror and disgust. "He's got it all; the hair, the eyes and those gorgeous muscles..."

"That's my brother, you little minx!" Vivienne cried, hitting her friend playfully. "Don't you dare talk about him like that around me! And if you're getting any ideas, you should know that he has absolutely no manners. He was trying to grope Bellatrix the other day and she would have hexed him if I hadn't stepped in."

Freya shrugged, rolling onto her side so that she was out of Vivienne's reach. "All right, all right! You deserved it after what you said about Lucius, I was just playing with you!"

"And besides," Vivienne put in, once she'd given up trying to hit Freya. "We all know who you think is the most handsome one out there. Or haven't you fancied Rabastan Lestrange since second year?"

Freya shook her head, trying to keep a straight face. "Don't be silly. Everyone knows he's infatuated with Rochelle Vittori. I couldn't compete with her even if I wanted to, which I don't!"

"Vittori's a prude." Vivienne waved a hand dismissively. "She'll never fall for him. Once he realizes that, your path is clear. Maybe he just needs a prod in the right direction."

Freya blushed. She quickly got to her feet, dusting off her robes and trying not to look embarrassed. "Well, that's enough chatter for today. I'm starving and if we don't hurry, we'll be late for lunch. Come on, then."

Vivienne got up as well and followed her friends to the Great Hall, as they joked around. Deep down, she was a little glad that Regulus Black hadn't come up in their discussion. She wasn't sure what she would do if her friends ever found out she was intrigued by the only boy in their year who never shot girls a second glance.

Regulus Black entered the Great Hall still in his Quidditch robes, after a long morning of practice. He was ravenous and he plopped down beside Mulciber, who was talking loudly about some nonsense that Regulus didn't care to pay attention to. If there was one thing he detested, it was people who talked too much. It was fascinating at times, the stupidity that often came out of the mouths of fellow wizards. Besides, he heard enough incessant chatter at home, courtesy of his mother.

"Nice practice, mate," Rabastan Lestrange acknowledged Regulus from across the Slytherin table. "You're getting quite good. We'll beat Ravenclaw next week."

"We will," Regulus promised. Lestrange nodded at him before turning back to Malfoy and Regulus gave himself a moment to appreciate the compliment. It meant quite a bit coming from Lestrange; he was a bloody good player and had been on the team since his third year, while Regulus had only gotten on it in his fifth. All the same, Lestrange was prone to using cheap tactics against his opponents, especially the Gryffindors. It's a shame, Regulus thought to himself. He has a lot of talent, he just needs morals.

Regulus ate quietly, while the rest of the table chattered. Although Slytherins weren't loud and usually maintained a better semblance of discipline than the other houses, the amount of gossip and rumours that circulated around probably exceeded all the other houses combined. Everything in Slytherin happened behind closed doors.

"No! He did that? You're joking!" a female voice exclaimed. It came from the other side of the table, but it was so loud that Regulus heard it clearly from his seat. He only had to look up once to know that the person talking was Vivienne Rosier, along with her friends Freya and Narcissa.

Regulus stabbed his fork into his food, resisting the urge to roll his eyes. If Slytherin had anything close to gossip queens, it was probably those three. They never seemed to stop yapping and it was usually about something completely juvenile and immature. Regulus thought they were silly. Who cared how short Fiona Hemway's skirt was, when there was bigger issues in the world? Somebody needed to teach those girls to grow up, but it wouldn't be him. He wanted nothing to do with Evan Rosier and Bellatrix Black's little sisters.
