A/N: Hey, guys! So if you read my other fanfic, This Is Our Fairytale, you may realize that I've mentioned that I am a huge Klaroline shipper (and practically ships Caroline Forbes with anything and anyone) and decided, hey, let's write a Klaroline fanfic because… well, why the hell not! This is sorta, kinda AU. Everything else that happened in the TVD and TO universe until TO season 3 are cannon except for the ones where Caroline is involved. I love idea of Caroline being a badass chick who takes no sh*t from Klaus or anybody and I also love the idea of Klaus actually have a friend and confidante he could truly depend on, like a best friend and also, I totally love the idea of the sire line, the vampires that comes after the Originals. I decided to mash up all those three together and now we have this fanfic. There'll be some Carlijah (I'm sorry, I just could help but to put these two together), some Klamille or Klayley (I'm not a fan of these ships but I'm not a hater either so just bear it with me) and probably some other ships too but the endgame will be Klaroline so don't you worry about that. I hope you guys enjoy it and don't forget to leave a review for it.

*English is not my first language so I apologize for any grammatical mistake or if the sentences doesn't make an actual sense sometimes.*

Pairing: Klaroline

Summary: His whole life, Klaus had gotten used to being disappointed and betrayed by everyone he knows and cares about, especially his own family but she was always an exception to that rule. If there is one person in his life who would never, ever betray him or let him down, it would be his one and only true friend, Caroline Forbes.

Of Darkness and Light

PROLOGUE

PEOPLE enjoys glorifying eternity. They wrote books, movies and God knows what else glorifying the idea of being able to live forever, never growing old, never getting sick and being absolutely invincible. That's why the thought of being a vampire, of being powerful, ageless and fearless are so appealing to them, that if you got to be all of that, it didn't matter if you end up being a monster, as long as you have power, nothing seems to matter. What most people doesn't know though is that all that power, all that eternity they seek, always comes with a price. Nothing is ever without a cost, every decision, every choice and every move you make, there will always be consequences. The most annoying thing about it is that sometimes, you ended up paying for someone else's decision, some else's choice, someone else's move.

That is practically the life story of Caroline Forbes, the former witch apprentice that lost her parents at such a young age and was taken by a coven of witches that resides in a Viking village. Every day, as she live and breathe the air and walk the earth with an unbeaten heart, she was reminded by the fact that this is not the life she had chosen for herself, that it was never her decision to be a vampire, a monster. It is the act of a person she loathe and loves with her whole heart at the same time. It's practically why she hadn't yet seek a way to end his pathetic life.

The former red-head now turned blonde let out a deep sigh as she twirled the glass of scotch in hand and watched as the liquid moved inside of the clear glass. Why the hell was she even here, in New Orleans anyway? She was having a great time sunbathing in the Caribbean with a hot male specimen that look like he just walked out of an Abercrombie ad or something, she would have even gotten laid with said male specimen if Klaus hadn't picked up his damn phone and call her. Damn him for picking up his phone and dialed her number – actually, damn him for existing all together because if it wasn't for him, Caroline would be peacefully dead by now. She would be a history long forgotten and she would have been perfectly fine with it. But nooo, Klaus couldn't have that. He just had to meddle into things and messed up everything. Although technically, the one she should hate is Esther – she was the one who decided to meddle with dark magic and changed her children into vampires that sets a chain reaction of a global size catastrophe in the form of blood sucking monsters – but still, it's Klaus' fault as far as Caroline's concern.

When she saw Klaus' name appeared on the screen of her phone that day at the beach, she simply ignored the call – she was still mad at him for what happened to Lucas, her vampire company back in the 20th century, so for all she cares, he could go to hell and it would not have mattered to her – but then her phone just wouldn't stop ringing and though the thought of throwing that piece of technology deep into the ocean had come across her mind, Caroline refrain from doing such thing – it's new and Caroline would be damn before she let Klaus ruin even that for her – and ended up answering his call.

Like a complete egotistical jerk he is, he demanded for Caroline to come to New Orleans because he 'requires her assistance' as if she was some kind of a low-life minions of his. Oh, the nerves that pompous ass had! Before he could even finished his 'demands', Caroline had given him a piece of her mind – which turned into her yelling at the phone for like two hours or so and no doubt attracting all the unwanted attention around her – and was so close to ignoring the Original for the next millennium when he played dirty and uses the 'friendship card'.

Honestly, Caroline doesn't even know why she even let him uses that card against her anymore. Like, when was the last time he acted like a friend anyway? That card had long been thrown away and left forgotten the moment Klaus decided to be… well, Klaus – which means he's being a complete ass – and decided that he can control her the way he controls his siblings and his minions. She should have just laugh straight at his face, well, laugh straight at his phone call when he started bringing up his so-called privilege as her friend but of course she didn't! Caroline Forbes is loyal to a fault, that is just who she is as a person. Whenever someone she cares about call for her help, she will always come, through heaven and hell, sun and the earth, she will come. Unfortunately for her though, that includes the complete psychotic asshat that drives her crazy all the time too.

Isn't that annoying though? How she just couldn't turn down Klaus after everything he had done. No matter how many decades, even millennium had passed, whatever transgression Klaus had done, Caroline just simply could not turn her back on him. He's her best friend, she would go through hell and earth back and forth for him if he'd asked her to, nothing will ever change that and Caroline hates it. She kept giving him chances, she kept giving him a pass for all the horrible things he had done and what did he gave her back in return? He turned her friends, killed her companions, threatened the man she loves and just ruins every single damn thing for her. Like, what kind of a friend does that?

Ugh! Why was she even here anyway? In New Orleans? She wants no part in whatever hell Klaus had gotten himself into or the ones he himself had raised on people, she absolutely have no interest in his diabolical plan to control the supernatural world and God, does she does not want to get involved in his family drama! She is so over the Mikaelsons and their feud! She is especially over the tug of war he kept having with Elijah– Ugh! Elijah… Caroline had totally forgotten about his reconciliation with Klaus recently. Apparently their long twisted and complicated feud had ended and they are now back in the bromance territory, at least that's how it was the last time Caroline had checked – you can never be too sure with these Mikaelsons. They're worse than the Kardashians! If Klaus is here in New Orleans, that means Elijah must be too – he is big on family and their 'always and forever' motto – and that alone makes the girl want to drown herself in a pool of alcohol.

She had sworn to never, ever, ever see Elijah's face ever again. Caroline had spent the last few decades making sure that she won't ever have to come face to face with that Original again but of course Klaus had to ruin it like everything else he had ruined for her. Why does she even bother to still care about these people anyway is beyond her.

Caroline took another deep sigh and downed the whole glass of scotch she had ordered, enjoying the burning sensation the alcohol was giving her before ordering a few more glasses. She reached about at least, ten of those glasses before she finally decided that she was drunk enough to deal with Klaus and Co. Word of advice to whoever out there that has to deal with the Originals, make sure you're at least drunk enough to forget what time it is before you go and see them or else they'll be too much for you to handle. Either way, you will definitely get a massive headache to deal with the next day but at least the alcohol was worth it, the Mikaelsons are so totally not.

After downing her last glass of scotch that evening, Caroline finally left the bar and made her way to meet the bane of her existence, Niklaus Mikaelson who just so happens to be her freaking Vampire Sire.
