Legacy of Mischief

Hello everyone, Selene – Daughter of the Sea here (and yes I changed my username, though I am still the same author). I know you're all tired of me adding new stories and not updating my other ones, but I got so many stories bouncing in my head that I just have to put them on here. I'm also trying a new direction this time, with a different type of crossover, so bear with me on this. Thanks.

Summary: It has been a year since the war with Gaea and her sons, and Perci has been keeping a secret from her friends. She is a demigod, true, but she is also a legacy of a god that is not even Greek or Roman, but a Norse god. When the Avengers arrive to try and find Loki's descendnet, trust is broken and truths are revealed. Why did Perci keep it secret? All will be revealed in time. Set after the Heroes of Olympus and The Avengers movie.

Disclaimer: I don't own either Percy Jackson or the Avengers.

Without farther adieu, here's the prologue.

Prologue~

Flames lit up the sky as a young Perci Jackson watched. Her mother just steps behind her, watching their only home go up in flames.

"What will we do, mama?" the five-year-old asked, turning her sea-green eyes on her mother.

Sally Jackson smiled sadly, looking at her daughter. "We survive, little one. The world doesn't stop turning just because of one disaster. It moves on and so shall we."

Perci nodded, eyes turned to her mom. "Where will we go?"

"There are two places I learned about from your father that would be safe, but we'll keep those options open for now. Let's find a cheap place to stay for the night and decide then, alright?" Sally asked.

Perci nodded, grabbing her mom's hand and together they walked away.

(Two years later, Near the wolf house)

"There you go, brat. A nice place for you to go and stay out of my hair," Gabriel Ugliano growled, as he dragged his seven-year-old daughter by the hair near what looked like an abandoned building. "You'll never bother me now, and hopefully no one who is normal." He kicked her in the side once before heading back to his car and driving away.

Perci sat up, wary of her bruised ribs as she watched her stepfather drive away. She knew that it was unlikely that she would survive with no supplies and only the clothes on her back. As she bit her lip to stop from crying, a voice rang in the clearing.

"What's this? A child abandoned by their family?"

Perci turned quickly and her eyes widened as a giant, pure white wolf stepped into the clearing. Her eyes widening, she scrambled to get up as the wolf came nearer. The wolf stopped a foot from her and sniffed the air then snarled.

"How dare a mortal lay a hand on a child of Rome?" The she-wolf, for it was a female voice that spoke, growled.

"Who-who are you?" Perci asked, sounding braver than she felt. "And what do you mean by a child of Rome?"

The wolf looked at her then nodded. "I am Lupa, Patron of New Rome, and the wolf goddess, little demigod. I call you a child of Rome as one of your parents is a Roman god, but I sense the conflict in you as if they are a mix of Greek as well. Very odd, but you will still be welcomed to Camp Jupiter, that is, if you make it there. There is also a fainter scent, not one of either Parthenon that I cannot place."

"I can do it. What must I do?" Perci asked, standing straight.

"Hush, little demigod. First you must pass my tests and survive. Only then, if you are still alive, will you be given the chance to head to the camp." Lupa snorted.

Perci nodded, understanding what Lupa meant.

"Smart, considering the smell that comes from you telling about your parent. And if I'm right, then you are his only demigod daughter. Follow me and your tests will commence." Lupa said then turned, heading back the way she came.

Perci steeled her resolve and followed. She would do her best to survive, and then show everyone that she wasn't one to be messed with.

(4 years later, San Francisco)

"Come on," a voice called. Perci turned to the speaker, a blonde haired boy that wasn't that much older than her. Jason Grace was a son Jupiter, one, who like her, wasn't supposed to be alive, as it meant that their fathers had broken an oath they had made decades ago.

"Where are we going?" She asked, looking at him. On both their arms, stood out three distinct markings: SPQR, the motto of Camp Jupiter, lines on their arms, telling how long they had been at camp (Jason had seven while she only had three), and then above the lines, the symbol of their godly parent. On Jason's arm, there was an eagle, the symbol of his father Jupiter. Perci, however, had a trident with a fainter symbol next to it, that of a snake. Her father was Neptune, but the second symbol, showing who's legacy she was, was a mystery as no god that they knew of had that symbol.

"We're going hunting, as there is supposed to be a tough monster nearby that is attacking any half-blood that comes through." He explained, his gladius in his hand.

"Are you sure it's okay for us to be here? I thought we had to get permission to leave camp." Perci asked, her two blades in her hands. Two of the weapons shone pale gold in the light, while the other was the color of pale bronze.

"Don't worry, Perci. I got permission." Jason said, looking around. "Hey, what's this?" He asked, spotting a poster for a missing child. "Perci, come look at this." He called.

Perci was walking over to see when a hand landed on her shoulder. "Looks like those posters worked boys." An older voice said.

Perci froze, looking up. Behind her, a police officer was smiling at her, calling for the others nearby. "We found the missing girl. You've been gone four years girl, your mama's worried." He said.

"I-" she started.

"I know, I know. You most likely don't remember much about her, but we'll be sending you back to her in New York. She was terrified for your safety, but with her husband, sorry, ex-husband dead, she wants you back home."

Out of the corner of her eye, she saw Jason heading for them and she shook her head in warning. He nodded and watched, worry in his eyes.

"Let's go, boys." The officer said, and with his hand still on Perci's shoulder, led her away from her best friend, neither of them knowing that it would be another six years before they saw each other again.

A/n: Whoo! Prologue is done. If you're wondering why I started with the story before either the books or the movie, it's because I chose to do it that way. I hope you all enjoyed it and I can't wait to see what you all say. PM me any questions you might have or ask in review. Also, if you got a better idea for the title let me know. Thanks!
