AN: Hi everyone who came across my story! Thanks for giving it a chance. I was inspired by BigTimeOT4's story Libérée Délivrée (please read the story, it's great).

In the first two years we will mostly see Elsa (and our beloved twins). Anna will appear now and then. In Elsa's third year Harry, Ron and Hermoine will join Hogwarts. Though you can, if you have any idea, for Elsa's first two years, let me know in the reviews, which are appreciated.

I don't have a beta reader and English isn't my native language, but I try to make no mistakes. If you find some, let me know, though I can correct them.

Disclaimer: I don't own Frozen or Harry Potter.

Now on to chapter one! Enjoy reading :-)

The Acceptance Letter

Eight years. Eight years had passed since the dark times ended. Eight years since Lord Voldemort, the most powerful and fearful wizard of the modern days, was gone and since eight years, the entire wizarding world knew the story of Harry Potter and his deceased parents Lily and James. And everyone knew of the events, which happened on October 31, the day Voldemort's cruel reign fell.

Voldemort and his followers – Death Eaters – murdered a lot of wizards and witches, who refused to join Voldemort's side. Lily and James Potter weren't an exception. Most wizards and witches who thought back at these times, only remembered the story of Harry Potter, the boy who lived. But, only a few people knew, that there were two girls, whose story was connected to the events, than it seemed it was.

Two girls lost their mother too; only four months before Voldemort killed the Potters and unbeknownst to him, would end his own reign over the wizarding world.

Eight years had passed since the girls' godfather brought them to Arendelle, a Norwegian coastal town, which was far away from their wizarding world, where no one would know and recognize the girls, until they were old enough to become a part of their world again. It was hard for their grandfather to leave the girls by strange people, who didn't know and understand anything about magic. They were – like everyone called non-magical people in the wizarding world – Muggles.

In the residence, which was connected to the rest of the town through a stone bridge, an eight-year-old girl sat on the comfy sofa in front of the large window in her room, which she shared with her older sister. Her alarm clock on her nightstand showed 4am, but the girl didn't care. It wasn't the first time she got up in the early morning hours to watch the sky. Usually she watched the Aurora Borealis, the Northern Lights. But it was summer and though the Northern Lights didn't appear. That didn't matter for the girl; she watched the moon, which fell on the town.

After a few moments, the strawberry blonde girl turned around and tiptoed to the opposite side of the room, where her sister lay asleep in her bed. With some effort the eight-year-old girl managed to climb onto her sister's bed. "Psst Elsa" she whispered, but her older sister remained asleep. The younger girl didn't give up so easily and sat down on her sister. But Elsa didn't move. With her full weight, the younger girl roughly shook Elsa. "Wake up! Wake up! Wake up!" she said, this time her voice was louder than before. Elsa sighed. "Anna, go back to sleep" Elsa mumbled sleepily. "I can't!" Anna exclaimed. With her back she lay on top of Elsa, laid her back of her right hand over her forehead and sighed dramatically. "The sky is awake! So, I am awake! So we have to play!"

Elsa sighed once more; she knew this game. Anna would wake up in the middle of the night, would wake her up and they would play. And in the morning, their foster parents would scold them for getting up in the middle of the night. There were hardly times worth mentioning in which Elsa resisted of a late play time with her little sister, but this time she didn't want to get up. "No, go play by yourself!" she replied and pushed her sister away, who rolled over the edge of the bed and plopped to the ground. Anna landed on her bottom and felt some pain for a moment, but the pain faded quickly as if it didn't appear. Anna was clumsy and fell at least once every day; therefore she was used to the pain. Anna sat pouting before Elsa's bed. She wanted to play! How could she persuade her big sister? Her bright blue eyes suddenly lit up, when an idea struck her. Quickly she climbed onto her sister's bed again and looked just for a moment mischievously at her peacefully sleeping sister. Carefully, Anna slid Elsa's left eyelid up, though Elsa was forced to look with her left eye at Anna.

"Do you want to build a snowman?"

That was it! This was the question Anna needed, though her older sister would play with her. Sheepishly Elsa grinned and opened her right eye too. With Elsa's brief nod, Anna hopped down her bed and ran to her closet. "You should change into some warm close. You will be cold" Elsa said motherly. "Not necessary" Anna said absently and rummaged through her closet, throwing shirts, tops, pants, shoes and jackets on the ground, until she found, what she was looking for. While Anna put on her brown warm winter boots, Elsa looked doubtfully at Anna's pink summer night gown, which had short sleeves. But then Elsa shrugged and slipped into her blue slippers, which matched her blue silk pyjama.

Three minutes later, Elsa and Anna raced through the house. They went along the hall, down the stairs and through another hallway. Both stopped for just a second in front of a door before Elsa opened it. The girls slipped through the door and entered the large dining room. Elsa closed the door behind them. Anna pulled Elsa in the centre of the room, the large dining table stood near the large windows, that made the room brighter and friendlier and it gave the girls plenty of space to play. Excitedly Anna looked with her big bright blue eyes expectedly at her older sister. The eleven-year-old girl could withstand her sister's big blue eyes just for several seconds.

"Do the magic! Do the magic!" Anna demanded expectedly.

Elsa raised her hands, which Anna closely observed with wide eyes, and formed an invisible small ball. In a blink of an eye, white and blue glowing snowflakes started to float around Elsa's hands. The snowflakes gathered in her hands and a snowball was formed. She briefly paused, when she thought her snowball was big enough.

"Ready?"

Anna nodded violently; grinning from ear to ear. Elsa threw her snowball till under the ceiling, where the snowball exploded and a slight snowfall rained on the girls. Anna jumped up and down in excitement and tried to catch snowflakes with her mouth.

"This is amazing!" Anna exclaimed happily. Elsa smiled at her little sister's joy. She loved seeing Anna happy. And when Anna was happy, Elsa was happy too and vice versa.

Anna admired her older sister; especially when Anna saw Elsa using her special ability, which made her sister unique in her own way. From the moment Elsa was born, she had the ability to control ice and snow. Of course, there were spells to create ice and snow, like spells to create fire, water, wind and other things, which were related to the four elements; however, you always needed a spell and a wand. And it were just minor spells, which would dissolve after several moments; just long enough to create what you want for the reason you want it. Elsa however, didn't need a wand or a spell. Her ice magic was closely related to her emotions; which sometimes wasn't useful; if she was stressed, scared or angry her magic could get out of control. But the times, when Elsa would lose control over her ability were rare, because she had trained with her grandfather, how to control it in every situation. Just in extreme situations, the possibility she would lose control was high. Her grandfather had once told her, there was beauty in her power, but also great danger and therefore it was very important for her to learn to control her power.

Elsa didn't know where her ability came from and how she got it. As far as she knew, no one in her family, there was neither in her mother's side or her father's side of the family, who had the same ability. And she knew no one, who had a similar ability or was in a similar situation as she was.

Elsa's ice magic also was the reason, why she looked different than the rest of her family. Her appearance clearly resembled her ability: Her skin was much paler than the others in her family, it looked almost white, her wavy platinum blonde hair was always braided and could also easily be mistaken as white, especially because there also were some snowflakes in her hair. Her eyes were ice blue, the purest ice. Several freckles around her nose and her rosy cheeks and lips were a great contrast to her pale skin. Matching her unique ability, Elsa loved the colours light blue and white and often dressed that way. Anna often referred to Elsa as the 'Ice Queen', because of her ability, her regal and graceful manners and sometimes because of her cold appearance towards other people.

When Elsa thought they had enough snow to build that snowman, she waved with her hands and automatically the snowfall stopped. Both girls rolled snowballs in different seize and put them together. Then both girls ran to the kitchen, grabbed a carrot and some old black coal. While Anna went back to the dining room, Elsa went into the small garden and looked for two fitting twigs, which they could use as the snowman's arms. It didn't take Elsa long to find two matching twigs and she went back to Anna.

Anna sat on one of the chairs at the dining table, while Elsa put carrot, coal and twigs on their place. Then she turned the snowman around, though it would face Anna. Elsa hid behind the snowman, put the twig-arms in her own hands and waved at Anna. "Hi, I'm Olaf and I like warm hugs!" she said in a deep silly Olaf-voice. Anna got up from the chair, threw her hands joyfully in the air and made a giggling sound. She ran to Olaf and Elsa. "I love you, Olaf!" she replied while hugging the snowman. Both girls giggled. Elsa then got to her feet.

"Watch this!" Elsa said to her sister. Excitedly Anna closely observed her sister, who stomped her right foot a little harder onto the ground. Immediately the ground under her feet froze and spread in a circle around the girls. Anna's blue eyes widened at the sight in astonishment. "Wow!" she said. It was the only word she could think of. Anna admired her older sister.

"Anna, please help me. I like to skate." Elsa said in her Olaf voice. Anna took the twig arms in her hands and pulled Olaf. Elsa helped with her ice magic and the two girls and the snowman skated together. Both girls laughed with joy. After skating with Olaf, they had a snowball fight, which Elsa won and after that they slid down some snow hills. At the end of the snow hill Anna fell face forward into another snow hill. She appeared in the middle of the snow hill and laughed, Elsa quickly joining her. Then Anna started to jump in the air, while Elsa conjured a snow hill for her.

"Catch me!" Anna shouted to her sister, while jumping in the air and landing on another snow hill which instantly appeared. "I got you!" Elsa replied smiling. Anna kept jumping and laughing. She jumped faster and faster and Elsa had trouble to keep up with her sister.

"Anna wait!" she shouted to her sister, "Slow down!"

But Anna was so focused on her fun that she didn't hear her sister's warning. Suddenly Elsa slipped on her ice and fell backwards, landing hard on her ice. Anna didn't notice that and jumped. Horrified Elsa saw Anna jumping from the last and highest snow hill she had conjured with her magic. Elsa quickly got to her knees and raised her hand. Not a second to late, another snow hill appeared in which Anna fell softly. She was still laughing. Elsa quickly got to her feet and ran over to her sister. "Anna! Is everything alright?!" she asked concerned. But Anna was still laughing and couldn't answer, however that was an answer for Elsa.

"That was close!" a sharp voice said suddenly.

Anna and Elsa, both surprised and shocked, turned in the direction of the voice. It was Kai, their foster father. "It could have been worse, if Elsa hadn't been able to act so quickly. Sometimes safety comes before fun, Anna. Remember that the next time." Kai scolded the eight-year old girl, who nodded with her head dropped. "No jumping from high snow hills! Do you understand?!"

"Yes Kai." Anna replied quietly. "And Elsa… you should be an example for your sister. You shouldn't have let Anna drag you in the dining room to play." Kai continued scolding. Elsa nodded silently. A cracked smile appeared on the stoic features of Kai. He couldn't stay mad at the girls for long.

"And now Elsa, please clean this mess up," Kai told the older girl. "After our snowball fight," he added laughingly and rolled a small snowball. He tossed it around and hit Anna, who hadn't expected it, right in her face. For a split second, Anna looked curious, causing Elsa and Kai to laugh. Then Anna also started laughing and the three were deep into a snowball fight – Elsa and Anna against Kai.

Gerda, Kai's wife, stood silently in the doorway; a warm smile graced her face. She loved the girls as if they were her and Kai's own daughters. And they couldn't stay angry for a long amount of time, although both girls could be very mischievous and often got into trouble, but after a few scolding words, their anger always passed as soon as it had appeared. "Breakfast is ready!" Gerda audibly announced after some minutes. Kai, who hadn't noticed his wife in the doorway, looked to her and forgot Elsa and Anna, who were forming another – this time larger – snowball. The snowball hit Kai right his face. Gerda, Elsa and Anna laughed and after Kai wiped the rest of the snow out of his face, he joined them. "Let's go eating," he said between several laughs.

Five minutes later, the family sat at the breakfast table. Anna and Elsa usually ate Chocolate Chip Pancakes – their favourite which wasn't surprising, because they loved everything with chocolate in it. Gerda put a cup of hot chocolate before the girls.A penetrating knock at the window disturbed the morning silence. "What is that?" Kai and Gerda asked in unison. "Mail!" Anna exclaimed with her full mouth. "Anna please chew and swallow, before you speak" Kai lectured her.

"Sorry"

Elsa in the meantime has seen the owl and got up from the table. She went to the window and opened it to let the owl, which had an envelope in her beak, in. The owl flew some circles in the room, then landed before Elsa on the table.

"Who wrote?" Anna asked curious. She was one of the most impatient people, Elsa had ever known, but Elsa loved Anna for who she was and her impatience definitely underlined Anna's personality. "Grandpa wrote…"

"Open the letter, Elsa!" Anna demanded and hopped from her seat, running to Elsa. She wanted to know, what their grandfather had written and she didn't want to wait any longer.

Ms. Elsa And Ms. Anna

Royal Alley 21

Fourth Bedroom on the Second Flour

Arendelle

"What do you think, Grandpa wrote about? Maybe about Hogwarts? Maybe it's your acceptance letter!" Anna shouted excitedly as if she was the one having received the acceptance letter. "C'mon Elsa, open it!" Anna said impatiently, shifting her weight from one foot to the other, after she got up and went next to her sister. Elsa slowly turned the envelope around and opened the seal, a beautiful seal, she knew way too well. Then she opened it and put out the letter and began to read aloud for Anna:

My dearest Elsa and Anna,

I am very sorry that I wasn't able to write earlier, but I was busy. I had to take care of some things. But I wanted to tell you the good news first-hand Elsa. You are accepted at Hogwarts. I think you (and especially Anna) already knew it. It isn't surprising, is it? Well I couldn't resist answering your acceptance letter by myself. Though, you don't have to do it. The school term will start on 1. September, departure is at King's Cross, London, platform 93/4.

Don't worry Anna, Elsa will be home a few months later during the Christmas holidays. I know that you will be sad after the first wave of excitement vanished. I know it won't be easy for both of you, the first few months of being away from each other. Anna, don't worry, your time will come. You will definitely receive an acceptance letter. And until then, Gerda and Kai will take good care of you. I am sure, they will do a lot of great things with you, though you will be able to tell Elsa about your months without her. Ah, before I forget it, Anna you will get a gift from me, because I couldn't come to your birthday party. I hope you enjoy your delicious gift.

Until my next letter (or until we see each other, Elsa), I wish you a great summer. By the way, don't be so mischievous girls! Don't cause Gerda and Kai so much trouble!

Love Grandpa

"Hogwarts! You will learn how to do magic!" Anna exclaimed admiringly. "Not that you would need it, I mean… you have ice magic… that is the powerfullest – I mean most powerful magic – I've ever seen…" Anna added in her rambling way. Elsa giggled at Anna's words. "You are going, right?! I mean, you have to! Mom was there and Dad and Grandpa! I mean, you are the first of us to go to Hogwarts, how cool is that?! I'm soooo jealous!"

"Anna, Sweetie, breathe" Gerda instructed to calm the excited eight-year-old girl down. Elsa on the other side was more reserved and although she didn't show her joy and happiness about the letter as her sister did, she shouted joyfully inwardly.

"That means, we have to travel to London in a few weeks." Kai said thoughtfully. "You should take some vacation, though we will be able to travel with Elsa to London. I don't want to let her travel alone." Gerda said, while Kai nodded. "Can I come with you and Elsa?"

"Oh Anna… of course dear. We wouldn't let you stay alone at home, while we are in London."

Together the four ate breakfast and discussed about the next few weeks. They only needed a few minutes to set up the travel plans. "Elsa, look! Here is the list with the school supplies you will need in your first year at Hogwarts!" Anna waved with another sheet in her hand. "Oh man, you have to read all those books?"

Elsa looked over her sister's shoulder to read what was written on the list. "Hopefully we need less books than you do."

"I don't think so Anna." Elsa shrugged. It didn't bother reading books and studying. Anna on the other side didn't like reading books for studying. She liked to read a few books about miracles, but nothing more. Her books should always have funny, romantic and adventurous stories – otherwise she wouldn't pick it up. "Do you think you will need a winter cloak. I mean, the cold never bothered you anyway. Why should you were a winter cloak?"

"We will see if it really is needed. Maybe, Elsa you can write your grandfather and ask about the winter cloak." Gerda suggested. Elsa nodded. "I will."

Four weeks later, the four travelled to London a day before Elsa's departure to Hogwarts. August passed quicker than the girls liked and especially Anna became more and more sad, when she thought about being alone at home, while Elsa was gone. Kai and Gerda booked two rooms in a hotel in London near the location, the Leaky Cauldron according to Elsa was. Though Kai and Gerda were Muggles, they couldn't see the pub and let Elsa and Anna lead the way. When they arrived, Gerda was a bit shocked to enter an old dark and shabby pub. In her eyes, it wasn't a place where young children - magical or not - should be alone.

The Leaky Cauldron was filled with chatting wizards and witches; some were drinking, some eating and others were just talking or sitting around. No one paid attention to them, which was quite alright for Gerda and Kai. The four quickly crossed the pub and exited on the backside, where they stood before a brick wall. "And now? Where should we go?" Gerda asked curious.

"Is there a way - maybe a door - at all to get to Diagon Alley? Or do you have to do magic?" Anna laughed about Kai's comment. "No, you have to tap a special brick three times. But whwere was it? Four times up and One right... no, no, no... two times up and four times right... Oh my god, I can't remember what Grandpa told us? Do you know it Elsa? Because if you don't and I don't then you can't buy or stuff and then you can't go to Hogwarts and study magic... and..."

"Anna! Stop!" Elsa interrupted her ranting sister. "Oops, I got carried away, like always."

Elsa nodded and used her magic to tap the right brick three times (three bricks above the trash can and two bricks to the right). Moments later the bricks parted and the four stood under an archway, which granted them entrance to Diagon Alley.

Busy witches and wizards passed the four on boths sides. Some entered or exited shops, a few were standing on the side and talked with other people. Some children pressed their noses against the glasses of the shop windows to stare into the shops. At first, they went to Gringotts to change money, though Elsa would be able to pay her things. Then they went to Madam Malkin's shop to get Elsa's uniforms.

While Elsa was in Madam Malkin's shop, the other three bought Elsa's books, one set of crystal phials and for Anna they bought a Mini-Quidditch-Field to play. Thirty minutes later, they met again and went to buy the other things like a telescope, brass scales and a cauldron.

At lunch they ate in a nice small café. Shopping made them hungry. "So, what do we still need?" Gerda asked, while they were sitting at a table, eating lunch. She put her full fork into her mouth. Anna handed Elsa the list. "I still need a wand and I can bring an animal with me. An owl, a cat or a toad..."

"No toad!" Anna protested, "A toad isn't the fitting pet for you."

"Fine. An owl maybe? Then I can send you letters. But I guess, there are owls at Hogwarts I can use."

"Then it's a cat for you." Anna said determined. Gerda and Kai agreed. "A cat then." Elsa agreed to. After lunch, they bought Elsa a snowy white cat and then went into the direction of Ollivander's shop. "What do you name the cat? Marshmallow would be cute."

"I don't know Anna. Maybe I call it that. Or maybe Olaf. What do you think?"

"No, Olaf doesn't fit and we named our snowman that."

"True."

"Maybe... Snowflake?"

But Elsa shook her head. "Hm?"

"Maybe I should call her Anna, though I only have to hug my cat, when I miss you during school."

"No way! That's my name!" Anna protested forcefully. Elsa laughed, "I was just joking. I think I call her Skjebni What do you think?"

"Cool The perfect name." Anna said.

Gerda waited outside Ollivander's shop with Skjebni; the shopping bags lay next to her feet. Kai, Elsa and Anna entered the dusty shop. But no one was there. "Hello? Is somebody here?" Kai said loudly. They all flinched when they heard a moving ladder. "Ah! Finally! Finally! I awaited you!" Ollivander an old wizard. "I need..."

"A wand, I know Ms. Elsa." Ollivander interrupted her. "I remember your mother and father buying their first wands, when they were in your age." he said and disappeared between two shelves. He appeared a moment later with a few long boxes. "Really? You knew mother and father?" Anna asked excitedly. Ollivander nodded. "Yes of course I do or I did. Horrible thing, what happened to them."

"Alright, let's try that one - cherry wood, unicorn hair, bendy and 10 inch."

Elsa took the wand and after Ollivander told her to swing it, she did. But the glass of the door shattered. "No, no, no! Clearly no!" Ollivander snatched the wand out of Elsa's hand and handed her the next. "Chestnut, eleven and one-quarter inch, dragon heartstring and swishy." Ollivander explained. Elsa waved the wand and a light tornado blew through the shop. Gerda outside became worried about the others, when she saw the tornado, but she didn't know, if she should go in and see, if they were all okay. But the tornado disappeared when Ollivander took the wand out of Elsa's hand.

"No, definitely no." he said and looked through the boxes to find another wand for Elsa to try out. "Hm," he mumbled, "maybe... Yes, why shouldn't you trry it out."

Ollivander handed Elsa another wand. "Arcacia, stiff, unicorn hair and nine and a half inch long." he explained. Elsa took it and felt warmth rising from her fingertips, which were wrapped around the wand. The feeling spread in her entire body and of the tip of the wand came white and blue sparks. "Yes, this is it." Ollivander said joyfully.

After Elsa paid the wand, they exited Ollivander's shop and all four walked into the direction of the Leaky Cauldron to get to the non-magical part of the city. The guests and receptionists in the hotel, where they had booked two rooms, looked confused at the things they had bought. Of course, they did. No one would think about taking a cauldron to a hotel. But Gerda, Kai and the girls ignored the looks, which they got from all people they passed.

"Good night Elsa. I love you." Anna mumbled wrapping her blanket tighter around her to cuddle into it. "Good night Anna. I love you too."

Elsa and Anna wanted to stay up longer and talk about Hogwarts, but they were too tired and their foster parents had sent them to bed after dinner. The shopping day had been exhausted. But their was one advantage: Elsa now couldn't think about tomorrow and worry about it, because she was too tired. As soon as Elsa's head hit the pillow, she was fast asleep, like her sister.

Tomorrow would be an exhausting day too, therefore, sleep was much needed.

Side not: Skjebni was derived from the Norwegian word skjebne and means fate or destiny in English.
