Jack Frost is responsible for bringing about winter every year. While bringing winter to Berk, a small Viking village at the edge of the known world, Jack meets a fierce and beautiful girl named Astrid. The village begins to accept Jack as one of their own, until they discover that he's not who they think he is. Jastrid. Slightly OOC. Takes place in the Viking Era.

Ch. 1: Winter Comes to Berk

Jack never did like the village of Berk. Not only was the weather rotten, but there were always dragons everywhere! Jack hated dragons with a passion. It isn't much of a surprise that the Spirit of Winter doesn't get along very well with a beast that breathes fire. Since the dragons gave Jack such a hard time getting into Berk, he always gave them an extra long, extra frosty winter, just out of spite. Needless to say, the villagers did not appreciate it. Not that Jack really cared. Anybody who spends all their time with dragons is obviously not right in the head.

It was early September, which meant it was time for another long, annoying trip to Berk. Oh joy.

"I'm heading out!" Jack shouted to the other guardians, who had met up at North's place.

"Not even going to say goodbye?" pouted Tooth. She had this strange attraction to him. He suspected that it had a lot to do with her strange fetish for nice teeth.

"You'll see me again in a week at the most, Tooth. It's not like I'll be gone for forever."

"You never know, those dragons can be pretty feisty," she teased.

"I can take a dragon anytime. Don't you worry," Jack said before taking off.

...

The trip to Berk was going by uneventfully, except for a mild scrape with a nest of giant buzzards. Jack was just starting to think he'd make it without any trouble, until he heard the telltale sound of dragon wings coming from behind him.

"Great, just what I need," he grumbled, turning to face the beast. It was a Deadly Nadder, one of the nastier species of dragons. It had a giant horn coming out of its nose, with spikes everywhere and leathery bat wings. It didn't seem thrilled to see Jack, either.

Jack flew away as fast as he could, shooting bolts of ice out of the end of his staff as he went. It didn't even seem to faze the Nadder, who simply melted each bolt with a breath of fire, singeing the tips of Jack's bare toes in the process. This startled Jack enough to cause him to lose his balance and fall a few meters in the air.

"Hey!" He shouted, shooting a bigger blast of ice at the dragon. The blast barely missed the dragon, but hit something else, something on the dragons back. Then Jack realized that he wasn't just going against a dragon—there was somebody riding it. And that somebody was frozen and falling to their death.

Jack snapped out of his surprised shock and shot down towards the ground, trying to catch the rider before it was too late. Jack may not have liked dragons, but he had no reason to kill a human.

Even though he was flying as fast as he could toward the earth, he barely caught the person before hitting the ground, hard. Looking closer, Jack saw that it was a girl, and a pretty one at that. She had big blue eyes and light blonde hair in a long braid down her back, and bangs that covered part of her face. She was freezing cold, even though the rapid fall had caused most of the ice to melt off of her. Not knowing what else to do, Jack took off his thick blue cloak and wrapped it around her, holding her close to him. The Man in Moon would most likely not be happy with him if he gave a human hypothermia, accident or not.

They sat like that for what felt like hours, while Jack waited for the girl to wake up.

What is she doing here, Jack wondered to himself. We're over a hundred miles away from Berk!

Jack was just beginning to doze off as the sun was setting. He was brought out of his half-slumber when he heard the girl start to wake up.

"Are you alright?!"

The girl's eyes shot open quickly, and she jumped up and away from him.

"Who are you? Where is Stormfly? What did you do to me?!"

"Stormfly? You mean that beast that tried to kill me? You have a name for it? Geez, you villagers are crazier than I thought…"

"Don't you insult Berk like that! You don't know anything about us! Who the heck are you, anyway? Some sort of flying imp? Maybe a skinny frost giant?" This girl certainly was aggressive.

"You know, you could be a little grateful. Maybe you could even say thank you? I kind of just saved your life!"

"Yeah, after you almost killed me!"

"And whose fault was that? I wouldn't have hit you with that blast if you and your beast hadn't been attacking me! What are you doing this far away from Berk, anyway?"

"I don't see why that's any of your business," the girl responded quickly.

"You aren't supposed to be here, are you?" Jack asked, eyebrow raised.

"Of course I am. I've been sent out to scout the neighboring islands," She answered, not meeting his eyes.

"So I can check that with the chief of Berk, then? And he'll agree?"

"NOOO!" She clamped her hands over her mouth, angry at herself for letting that slip. "Please don't tell them I'm out here. I just wanted to see what it was like outside of Berk."

"Hmmm. What's in it for me?" Jack teased, crossing his arms and putting on his best smirk.

"I won't tell them about the whole flying-guy-who-can-shoot-ice-from-a-stick thing, and you don't tell them that you saw me out here?"

"Sounds good to me. Now, I'll accompany you back to Berk if you promise that your Skyfly—"

"Stormfly!"

"Whatever. I will help you get back to Berk if you promise that your dragon won't burn me to bits."

"We have to find him first." As she was saying that, the dragon flew out from where it was hiding behind the tree line, knocking her over and licking her face with his lizard tongue. "Stormfly! I was worried about you!"

I'll never understand Vikings, thought Jack.
