A/N: I first posted this on AO3 a while back when the forth season of Originals had started airing and gave me family feels and that's what inspired this story. I love Klaroline and I love the dynamic between Klaus and Marcel and so I wanted to play around with it a bit.

I hope you like this Canon AU. Where Caroline is a part of the Mikaelson family but is not an original. Just a really, really, really old vampire. It's more angsty than my last Klaroline story though.

Caroline Forbes had lived a very long life. Centuries. Centuries she spent beside the most feared vampire in the world. Klaus Mikaelson.

But that was a long time ago. A life that was so far removed. She hadn't seen Klaus since he fled New Orleans with his siblings, not once looking back.

It had hurt that he had just left her behind, even if he thought her good as dead. She had spent hundreds of years loving him but that night she learned love was fleeting when faced with death.

But not all love was fleeting, not love built between mother and son. One good thing had come from being with Klaus. When he took in a small boy who had been nothing but rift raft he had given her something she didn't think she would ever have. A son.

And she did love Marcel as if he were her own flesh and blood. She had stood by his side ever since, had been there when he woken and he found most of his family gone all accept for the only mother he had growing up.

She stood by him even as he took the Mikaelson's plans for the city and built it in his image. She stood at his side as he built his Kingdom and his ranks.

Their family may have abandoned them but they would never abandon each other.

She was once known as Caroline Mikaelson but that was a long time ago. Not many remember there ever being a Caroline Mikaelson.

Instead she was known as Caroline Forbes and known as Marcel's oldest and most powerful ally.

Marcel had spent the last century building his kingdom, surrounding his self with his guys, he trusted them and their loyalty but there wasn't anyone he trusted more than Caroline.

She was the closest thing he had to a mother, who stood by him no matter what, who was there when he woke from being attack by Mikael who never once turned her back on him.

His guys knew to treat her with the respect she deserved and were loyal to her just as much as they were loyal to him.

Caroline was loved among the supernatural of New Orleans.

She was a constant in his life and more than his inner circle she was his family. And she proved it time and time again when she was always there for him. She was the one person he trusted to never leave him for dead, to never leave him behind.

The last thing Klaus expected to find in New Orleans was Marcel and Caroline. He had spent the last century believing them both to be dead at the hands of Mikael.

He spent years grieving them, he couldn't speak Marcel's name, couldn't bear to so much as hear Caroline's. The pain of their loss was so much it was easier to forget even if it was an impossible task.

There were moments where he would think of them and the pain became too much. To the point where he avoided New Orleans. Hadn't so much as stepped one foot back in New Orleans since.

There were times he felt Marcel's ghost haunting him, reminding him the loss of a child.

And he was unable to escape the void that losing Caroline had left inside him, he had tried to fill it over the centuries but nothing work. He still saw her in dreams, he still found himself sketching her, he still found himself whispering her name when he woke, sometimes her name left his lips like a prayer and other times like a curse.

It was a loss he never recovered from and one he didn't believe he ever would.

When Katerina said there were witches in New Orleans working against him the last thing he wanted to do was go to the city where he lost two vital pieces of himself but he wasn't about to let some arrogant witches think they could come after him, the most feared vampire in world, the original hybrid.

He would take care of the problem quickly and then leave New Orleans not wanting to be there longer than he had to when just being in the city made him want to tear everything and everyone apart leaving a bloody path in his wake of bodies and bloody entrails because why should the city and all its people continue to go on when Marcel couldn't.

When Caroline couldn't.

As far as he was concerned the city was dead and so should everyone else in it who weren't Marcel or Caroline, wanting everyone to suffer as much as he has suffered.

A/N: I know this is short but its only the introduction to the story. My chapter are usually longer. Thanks for reading and I hope you like it. Feel free to leave a review if you like.
