So... How about a Frozen and Harry Potter Crossover? First time I have ever seen one, and perhaps I am the first to do this?

I only own my OCs and ideas and crap. I don't own Harry Potter or Frozen.

Let It Go

~Prologue~

Kristoff and Anna Bjorgman were expecting their frist born child any day now. They planned to make Elsa, Anna's sister, the godmother of their baby as well.

Elsa was the Queen of Arendelle, and she also had the power to create snow and freeze things. The whole kingdom had had their share with this power about four years ago, when Elsa got angered by her sister and froze the whole kingdom.

What worried the young couple the most was that they lacked information if Elsa's power was a genetic or not. What would the kingdom do with another royal with the power? They dreaded to find out.

Our story starts on a snowy, bright, Tuesday morning. The date was January first, and at exactly nine o'clock in the morning on New Years Day, the daughter of the young Bjorgman couple was welcomed into the world.

Their first born child was a girl. They decided to name her Winter Elsa Bjorgman. Her hair was platinum blonde- like snow, almost- deep, green eyes, and skin as pale as snow. She took over her Aunt (and godmother) Elsa in the appearance department, but when Elsa first saw her when she was brought home to the castle, fear was easily shown in her own green eyes.

"Does she... Have it?" Elsa asked, curious and fearful.

"We don't exactly know yet." Kristoff said, holding his baby girl, who was reaching her arms out towards the air.

It was then that their worst fear was confirmed.

Ice shot out of Winter's hand, freezing one of the sections on the floor of the Enterance Hall. Winter giggled and froze a plate of chocolate in the corner of the room.

In any normal circumstance, Anna would say "No! Not the chocolate!", but this circumstance was more important than that.

"She has it! You need to see the Trolls, Anna, Kristoff! She has what I have... The Trolls might have a cure for her..."

After much pleaing on Elsa's part, Kristoff, Anna, Elsa and Winter traveled into the forest, and watched as the Trolls rolled out of their rock form.

"What is it- is this the new baby?" Grandmother Troll asked.

The new parents nodded, and Elsa sighed as she held her goddaughter.

"She has my curse. The Frozen curse. Is there a way to cure it? I will not have my goddaughter go through what I had to go through." Elsa protectively said.

"Yes, their is..." Grandmother Troll began. "It will only work at age eighteen. At age eighteen, she will go to Hogwarts School of Witchcraft and Wizardry, where she will learn to controll her magical powers, and the Frozen curse will be lifted from this family for ever."

Kristoff and Anna glanced at eachother, then at Elsa's pleading face, and then finally at their baby.

"She will go at eighteen. What about now? Shall we..." Kristoff trailed off.

"Close the gates?" Anna said, smally, tears welling up in her blue eyes.

"It may be for the best. Keep Winter inside at all times, until age eighteen. You may go out, Elsa, Kristoff, Anna and any other children you may have- but you must keep her inside."

It was the last thing that they wanted to do, but they had to do it.

Within four years, Winter finally asked, "Why can't I go outside?"

"Because... It is unsafe." Replied her father.

"But you two and Auntie Elsa and Olaf can! Why can't I?"

"It is too dangerous out there!"

"But you've said that all these years, mama! I want to! I NEED TO!"

And so ice shot out of Winter's hand, and hit the picture of fruit on the wall. Winter looked at her parents, scared. Her breath shaky, she asked, "Is this why?"

They nodded, and Winter ran to her room.

At age five, Winter acquired a baby brother by the name of Jacob. He had Anna's hair and Kristoffs warm brown eyes. He was the perfect baby- plus, he didn't have the curse that his older sister did.

The one time she did hold him was the time that she knew she had to wear gloves. Jacob's blankets were freezing at her touch, and she quickly shoved the baby in her father's face.

So, she got gloves from her mother that she was never to take off.

At age seven, Winter also acquired a baby sister. They named her Summer, and she had Kristoff's blonde hair and Anna's blue eyes. She didn't get the curse either.

Winter never had the pleasure of holding her baby sister, nor did she want to.

By age nine, she became very introverted, and often took refuge in her room. It took days at a time to persuade her to come out and have a simple meal, and it got worse and worse each day. She ended up seeking refuge in her room, only talking to Olaf.

At age eleven, Jacob started going to school in the kingdom, and made many friends. Winter, of course, was jealous.

In fact, it was not until age fifteen that things took a turn for the worse for Winter Elsa Bjorgman.

She had had enough with it, and her ten year old brother and eight year old sister actually saw their sister fully for the first time. It was not the best time to see her.

"I want to go outside the gates, mother, father!"

"You can't, Winter." Her father consulted.

"I NEED TO!"

"But you can't! It's dangerous!" Her mother exclaimed.

"But why do you let Jacob and Summer out there? I have never seen the sun! I don't know what it looks like!"

"YOU CAN'T GO OUTSIDE, WINTER!" Exclaimed Anna, who was normally the calm one.

"Winter- you can't..." Elsa agreed with her sister.

Winter felt tears roll down her cheeks. They froze as the fell to the floor.

"Fine! I'll let the storm range on! This perfect girl is gone!" She cried, and looked at her family before running out of the castle, something she never has done before.

She ran through the kingdom of Arendelle, ignoring the people who in her way. She raced across the lake once it froze at her touch.

Racing into the forest, she ran to the highest mountain in the wood. She used her powers to create steps to reach it, and she reached the top, creating a castle made of ice.

She unclipped her dark violet cape from her dress, and let it fly into the sky behind her. She ran her hand through her hair, making the bun fall into a beautiful, messy French braid. Her dress soon turned into a long white and blue gown that she often saw her Aunt Elsa wear.

Once she opened the door to the ice balcony that she made, she oversaw the kingdon she never knew of.

"Let the storm rage on..." She smirked, "The cold never bothered me anyways."

I hope you guys like the Prologue. I think it's pretty good, but I'm suppouse to think that.

Hope you enjoy!
