Prologue

England, 1492

Lydia pushed her dark brown hair out of her eyes as servants packed up her bags for her. She was leaving England, leaving her brothers. If she had realized how dangerous a task that was, things might have ended up differently for her.

Lydia couldn't help but feel a little guilty, for she was breaking a promise by leaving. And Lydia never broke promises. One thing she praised herself on was her loyalty, how she never, ever broke a promise. Lydia's word meant something. Or, at least, it used to.

She had promised her little brother, Niklaus, several things. She promised she'd help him break the curse their mother placed on him, she promised her loyalty, but, above all, she promised always and forever. Along with Rebekah and Elijah, she promised Klaus always and forever.

And now she was turning her back on all of those promises.

Leaving was definitely not the most honorable thing she had ever done. But she was finally seeing Niklaus in a new light. She no longer trusted him. She had to leave before she ended up like Finn. Kol, ironically, had been the smartest out of all of them. As soon as Finn was deposited in his coffin and hidden only God knows where, he was gone. Elijah, Rebekah, and Lydia had stayed, though. But now, almost four hundred years later, Lydia was leaving too.

The Niklaus she called a brother now was not the same Klaus she grew up with, took care of. He wasn't her baby brother, not anymore. She realized that the second he threatened to kill Elijah if Katerina wasn't found- Katerina, the doppelganger of Tatia. Katerina, who Elijah had foolishly fallen for. Katerina, who had been "courted" by Niklaus, when, really, he meant to sacrifice her and break his curse. Katerina, who had escaped with the help of Trevor.

So now Lydia was leaving. She had urged Elijah to leave with her, but he stubbornly insisted to stay, that Niklaus was still their brother, that they gave him their word. Lydia was almost tempted to stay as well, but her sense of self-preservation won out and now she was quickly packing her things, hoping to leave before Niklaus realized what she was doing.

"Thank you for your services," she told the servants, indicating their dismissal. They bowed their heads before leaving the room. Lydia sighed and started towards a book shelf, debating internally what books she should bring with her. She didn't even know where she would go. Check on Kol, maybe?

"What are you doing, Lydia?"

Lydia stiffened at his voice. She had to act normally, though. "Has Katerina been found yet?" she asked, completely ignoring his question.

Lydia turned around to look at her brother. He looked eerily calm. Scarily calm. The kind of calm that people were when they were about to snap. Lydia knew Niklaus almost better than anybody else. She knew that when he snapped, people lost their lives.

Klaus gritted his teeth, the muscles in his jaw tightening noticeably. "No, she has not. But, no matter. I will find a way to make the doppelganger pay. Not only did she run away, but she took the moonstone with her. She will regret her decision," he told her.

Lydia knew that somebody the doppelganger cared about was going to die, her family most likely. She looked back towards the bags on her bed, and Klaus followed her gaze. "What are you doing, Lydia?" he repeated, this time with a sharp edge in his voice. He knew exactly what she was doing.

Lydia took a deep, unnecessary breath. "I am leaving, brother."

Those four words put a noticeable change in Klaus. His eyes darkened, barely concealed rage hidden in the contours of his face. He stalked slowly towards his elder sister. Lydia stood her ground, though. She didn't cower in fear. She didn't stutter out an apology. She was unafraid of her little brother. And that made him only angrier.

"Are you now? And where do you plan to go, sister?" it was a sarcastic comment, slightly patronizing. Lydia held her head high and answered it seriously, though.

"I am not sure. Rebekah is in France right now, is she not? With Kol, I believe. I bet those two are at each other's throats as we speak. I better go make sure that everything is alright-"

She gasped suddenly when Klaus slammed her against a wall, hand on her throat. His eyes were full of rage. That was a downside to her little brother being half-werewolf. He suffered from werewolf rage at times. It was what made him so dangerous, his rage. It made him impulsive.

Lydia calmly placed a hand over Klaus', the one that was clenched around her throat. "Unhand me, brother, if you know what's good for you," she said calmly, though her voice was serious, her brown eyes darkening with anger.

"You promised, Lydia. Did you forget about your promise or are you no longer a woman of your word?" Klaus asked, his grip loosening slightly.

"I did not forget, Niklaus. But there is nothing more I can do. The doppelganger has fled, the moonstone is missing. I'm afraid that your curse might never-" her words cut off into a choked gasp, as Klaus tightened his gasp.

Quickly, with the strength and speed only an original could possess, Lydia slipped from Klaus' grip and slammed him against the wall by his throat. Her eyes darkened, though her truly demonic face- the face of a vampire- didn't appear. She didn't need red eyes and fangs to be menacing, to be terrifying.

"Don't you ever do that again," she said slowly, meaningfully. "I am not one of your lackeys, Niklaus. I am your sister and an original vampire and I will be treated as such."

Lydia let go of Klaus and turned her back on him. Slowly, she began to walk towards her bed again. "I am sorry, brother," she said quietly, shamefully almost. "Really, I am."

"As am I, sister."

Lydia's eyebrows furrowed and she turned around to ask Klaus why he was sorry, when he gripped her suddenly with one hand and, using the other, shoved a dagger with the ash of the white oak tree into her heart.

Gasping, Lydia's brown eyes went wide. She stared accusingly up at her brother, her killer. He stared back down at her, blue never leaving brown. She saw something flicker in them- was it regret? She hoped it was. She hoped her baby brother regretted killing her.

She felt her body shut down. She felt herself grow weak until she couldn't stand anymore. Klaus supported her in his arms as her skin grew gray and the veins protruded out. When he laid her gently down on her bed, Lydia Mikaelson was already dead- or good as.

A/N: New story I've had in my head. I really wanted to write an original sister story so badly. This story kind of follows season 3, but not really. I will incorporate some things from that season into here, but some things will change. Like always, I'm not following the show, I'm following the story in my mind.

I think I mentioned it in the prologue, but Lydia is the third oldest- at least in the story, the oldest is Elijah, then Finn, Lydia, Klaus, Kol, Rebekah, and then poor little Henrik. Just in case you're curious.

Drop a review, please!
