Chapter 1 Diagon Alley

/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/

Without sound, Jack landed in front of the Leaky Cauldron. He brushed some snow of his dark blue robe and opened the door to the pub.

The inside was dimly lit with a stuffy atmosphere and a fire was smouldering in the corner. Jack wrinkled his nose. He had never gotten along with fire, which was understandable since he was the spirit of winter.

The room was filled with people. Wizards and witches with colourful pointed hats and long robes sat at the large tables, deeply immersed in their conversations.

None of them looked up as Jack entered the tavern. They merely shivered slightly as the wind make its way through the bar.

It was a cold day. Courtesy of yours truly, Jack Frost.

Grinning, Jack made a big circle around the fire as he walked towards the back entrance of the room. He stepped through the door way, into a small backyard.

Jack raised his staff and mumbled: "Diminuendo!"

The staff shrunk to the size of a normal wand, yet it still had the woven design of its initial form.

He reached into his pocket and took out a silver pendant. It bared a pretty snowflake design. The spirit placed the chain around his neck and felt the power spreading through his body.

Jack had made the pendant a few years back, when he got tired of people not seeing him. It made him visible to normal people.

He wore it a while but it pained him that, although people could see him now, they didn't truly believe in him. He was the spirit of winter and he wanted to be believed in. That was his goal.

When he had worn the pendant, he spread his name the best he could but nobody truly believed. He became a myth instead. The myth of Jack Frost, who nibs on your nose, if you aren't dressed warmly enough.

One-day people would truly believe in him and he wouldn't have to wear it anymore. He couldn't depend on a pendant for all eternity.

But right now it was necessary.

Jack had known about the wizarding world for a long time.

When one was immortal, a secret society as noticeable as this wasn't very secret. He had always been a brilliant prankster and prided himself in sticking his nose in other people's business.

The spirit had witnessed the wizarding war fourteen years ago.

He didn't interfere even though it pained him to watch so much death and not being able to do anything about it.

Jack had watched many wars over his three hundred year long live. Muggle wars mostly. And he didn't take part in any of them. He wasn't a muggle and he certainly wasn't a wizard. It wasn't his place to interfere.

But this time was different.

Lord Voldemort was back.

A second big wizarding war stood before.

And this time Hogwarts, school of witchcraft and wizardry, stood in the centre of it.

Jack had always had a soft spot for children. He loved making them laugh. Loved watching them have fun in the snow. Loved watching them mature and grow up.

He had to do something.

The daily prophet was making Harry Potter, the same boy who had ended the war fourteen years ago, out to be the bad guy.

They called him a liar. He who had defeated Voldemort before, he who had saved Hogwarts again and again, he who was only just a boy.

And so Jack decided: He would attend Hogwarts for the year.

He didn't like the idea.

School was boring, always is, and Jack, who had experienced enough boredom in his live, didn't look forward to it.

It was necessary, that he knew, but it would be hard. Hiding his powers from everyone around him, not being able to fly whenever he wanted to and he had to gain Harry's trust on top of it.

Jack sighed. No point in thinking about it now.

He stepped forward and started counting the bricks of the wall in front of him. Three up and two across.

He tapped the brick with his shrunken staff three times. A thin husk of frost coated the brick.

At first nothing happened but after a few moments, the wall started moving. The bricks shuffled to the side, forming a large hole.

Jack stepped through the wall onto a busy street, full of people and colourful shops of all kinds.

He had been here a few times before when he was invisible but it was still a breath-taking sight.

The spirit tucked his pendant under his robe before looking at every shop with interest. Muggle streets didn't even come close to the variety of shops that were present here.

A cluster of teenagers stood around a broom shop. Jack looked over their shoulders at the broom they were admiring and chuckled. He could easily outfly it. Owls shrieked as he walked past them. Animals could always sense that he was different.

Jack made his way over to Gringotts, the bank ran by goblins.

He got some odd looks as he stepped through the crowd. It wasn't surprising since his white hair and piercing blue eyes weren't a common sight. Plus, he wasn't wearing any shoes. He would have to wear them at Hogwarts and wanted to enjoy his bare feet as long as possible.

The spirit stopped in front of Gringotts to read the sign on the door.

Enter, stranger, but take heed

Of what awaits the sin of greed

For those who take, but do not earn,

Must pay most dearly in their turn.

So if you seek beneath our floors

A treasure that was never yours,

Thief, you have been warned, beware

Of finding more than treasure there.

Jack grinned. Goblins always had been a bit eccentric. Just his type of people.

He pushed through the door to find the familiar marble hall. A goblin bowed to him at the door and pointed him to a free shelter.

"Thank you", said Jack and lowered his head respectfully.

He stepped up to the strict looking goblin at the shelter.

"Hello, my name is Jack Frost. I would like to withdraw some money from my vault", he said with a sheepish grin.

He would have to take on a different name at Hogwarts but his vault was registered under his true name.

"Key?", asked the goblin and held out his hand.

Jack took out a small silver key, which had frosted over slightly and handed it to the creature.

It studied the key for a moment before nodding sharply and calling over another goblin.

The way down to the vault took a while but Jack didn't mind at all. He loved the fast and exhilarating ride. It reminded him of his flights through the clouds and he laughed the whole way.

His vault wasn't very full since he didn't make much money in he short time he wore his pendant but it would have to do for the year. He didn't need much anyway.

When Jack finally stepped out of the bank and squinted in the sun light, it was just past noon. He would have to hurry if he still wanted to make it to the weekly snowstorm in Alaska in time.

He quickly made his way into the first shop, Flourish and Blotts. Better get the worst part over with first.

Jack had never liked books. They were boring and he could think of a hundred different things he could do with his time instead. Another reason why he didn't like school. Too many books and too much study time.

He found his books easily since he just asked the young shop attendant for all the necessary school books for the fifth year at Hogwarts.

The young lady looked at him a bit dazed and blushed a little when Jack asked her if everything was alright.

He handed her a few Gallons and then made his way over to the next shop.

When he bought his robes, Jack reluctantly also tried on a pair of shoes. He felt restricted as soon as he put them on and pulled them off again quickly. The middle-aged shop attendant looked at him strangely but didn't say anything as he gave her a small smile.

Jack made a few last stops and when he finally had everything, made his way back to the Leaky Cauldron.

With full bags, Jack stepped through the whole in the wall again.

He took of his silver pendant and placed it back in his pocket. Then he took out his staff again before mumbling: "Engorgio!"

The staff grew back to its original size and Jack gave a relieved laugh before grabbing his bags.

"To Alaska, my friend", Jack said to the wind and laughed as it gathered around him and lifted him in the air, away from London.

This takes place bevor the events and The Rise Of The Guardians and wont star any of the others except Jack, who isn't a Guardian yet. It will be close to canon at times but it will be different later on. I'm a slow person and it takes me lots of times to write, especially since English isn't my first language, but I'm on summer break right now and have lots of time for this. I haven't uploaded on this site before and it might take me some time to get used to this but I'll try my best.
