Hey everyone! Maybe you know me, maybe you don't, but that doesn't matter! This is my first attempt at a crossover, and I hope it will turn out well. For those who don't know me: I try to post a new chapter once a week, and if I won't be able, I will let you know!

This chapter might be a bit short compared to what I use to post, but I really want to know what you think of it. It will be centered around Jack, Hiccup will appear later in this story.

Well, I don't know what else I could say... Let's just begin with this story!

It was the night of December the 22th. A think blanket of snow adorned the city of Burgess and in only a few houses the lights were lit. The moon shone brightly, making everything just a little visible. Visible enough to see the houses, the traffic lanterns, the woods at the edge of the village and the boy that sat on the center of a lake in the woods.

The boy wore a blue hoodie, brown pants and had bare feet. But that wasn't the most outstanding. If you would look a little closer, you could see that the boy had snow white hair, and if you looked more closer, you saw his icy blue eyes.

His name? Jack Frost. Although he looked seventeen years old, he really was much older than that. Jack didn't know when his birthday was exactly, so he decided to make the first day of winter his birthday. That meant that he was 319 years old.

Yes, two years had passed since the fight with Pitch. Two years had passed of Jack being a Guardian. For two years, Jack had believers.

But right now, that wasn't what Jack was thinking of. He was thinking the past few hours. Or actually, he was wondering what had happened the past few hours. Because he couldn't remember. He felt like he'd just awoken from some kind of trance. He couldn't recall how he'd ended up here. The last thing he remembered was that he'd frozen some elves again at the Pole, and that Phil was chasing him for painting the pile of toy-robots Phil was painting red, blue.

His thoughts were interrupted when the wind started to blow softly at his skin, but didn't whisper anything. And that was something that the wind did rarely. What happened?

'Wind? What's wrong?' Jack asked, wondering if he'd done something wrong. But the wind said nothing. It just kept blowing slightly, bringing the cold with it. Not that it really mattered to Jack; he couldn't feel cold. But still. What could've happened to make the wind stop talking to him?

Jack realized he was still sitting on the ice, and with surprisingly much effort he managed to stand up. Why do I feel so numb? Jack thought. He looked around, and it occurred to him that is was night. Judging by the moon, probably somewhere around 2:30 am. The moon, Jack suddenly thought. Maybe Manny knows why I woke up here. Jack looked up, and saw that the moon was shining brighter.

'Hey Manny!' Jack said aloud. 'Maybe you know why I am here?' But to Jack's –not so much- surprise, the moon didn't respond. Jack looked at the moon for a little longer, and that was when he realized he didn't have his staff. He looked around, the panic clearly shown. He sighed when he found it lying a few meters away from him. He walked towards it, and tested it by touching the ice from the lake with the end of his staff, but nothing happened. Jack frowned at this. He was surprised that the staff didn't work. Normally, beautiful flower patterns would have appeared on the ice, but now nothing happened. Jack examined the staff closely, looking for anything that could have blocked the icy magic, but he didn't find anything. Just then he noticed that there wasn't any frost on his staff, nor on his hoodie. Panic rose within Jack. What was happening? He looked around again. He had to find someone. Someone who could explain what was going on.

'Jamie…' Jack muttered. He jumped in the air, and was relieved when the wind caught him. 'Take me to Jamie,' Jack whispered. The wind obeyed, and soon he could see the lights that came from Burgess. He knew exactly where Jamie lived. Since the defeat of Pitch, what had happened almost two years ago, he visited the boy and his friends frequently.

Jack realized that he'd been on the lake for quite a while, because when he flew through the air, the sun was already rising. While Jack was swirling through the air, he remembered that Jamie had Christmas holiday, and that meant that they could be together the whole day.

He smiled at the thought, and then went towards the town.

It didn't take long for Jack to reach Burgess, and it only took about fifteen seconds to reach Jamie's house. Jack knew that Jamie was still asleep though, so he decided that Burgess could do with a little more snow. Jack flew up again, with Wind's help, and raised his staff towards the sky. He thought about the snowflakes falling down at a gently pace, just like every other time he wanted it to snow.

Only, nothing happened this time. Jack tried again, and again, and again, but it seemed like he couldn't make it snow. Again he looked at his staff. He was sure that there was nothing wrong with it. So why couldn't he make it snow? For the 302 years that he'd been Jack Frost, nothing like this had ever happened.

Jack descended towards the window that belonged to Jamie's room. The time went past really quickly. Judging by the clock on Jamie's nightstand, it was 7:39 am.

But then he saw it, in the reflection of the window. Yes, he saw himself, obviously. But that wasn't the thing that had bothered him. When he looked at his own reflection, Jack saw to his utter surprise, that his white hair had turned brown, and his eyes were turned into a hazel brown. Just like his past self. When he was Jackson Overland, and not Jack Frost. He stumbled backwards, and only too late did he realize that he wasn't on the steady ground below. Jack came down with a thud, the wind not being able to catch him in time. Groggily he sat up, and rubbed his head a few times. It wasn't like he hit it or something; it was just an unconscious action. After he adjusted to the pained feeling, he grinned. Jack never was the one to mourn over something like this for long. He was able to always see the fun side of it. Too bad it took him 300 years to remember that.

Jack waited for Jamie to come outside, and although he didn't like to wait much, he knew it would be worth it. Every time he was with Jamie, was something to never forget.

After what seemed like hours, Jamie exited the house, and went towards the park. To meet up with his other friends, probably. He hadn't noticed Jack yet, so he decided to follow his first believer.

Jamie was the first of his friends. Only a few people were occupying themselves at the park. Jamie looked around to make sure that he was the first, that he hadn't overlooked someone. Jack could see Jamie was a little bit disappointed to see that he was indeed the first. The boy sighed a little, but was soon distracted with the damp that formed in front of him.

'Hey, Jamie!' Jack called. He didn't want the boy to feel alone, so he decided it was about time that he took notice of the Winter Spirit. But Jamie didn't hear him. He was busy playing with the fog that appeared every time that he breathed, and didn't pay attention to his surroundings.

'Jamie?' Jack found it strange that Jamie still didn't hear him after the second time. Maybe he was fooling the Spirit by pretending he didn't see or hear him. But that wasn't something for Jamie to do. He knew all too well that Jack didn't like such games. It reminded him of his lonely years, from before he became a Guardian. Jamie knew that Jack was sensitive about that time. So why did he act like this right now?

Tired of Jamie acting like that, Jack went to stand in front of him. 'All right, Jamie. You know that isn't funny. So please can you-' Before Jack could finish his sentence, Jamie turned around and ran.

Right through him.
