Chapter 1: Beginnings

"It was supposed to just be a fun night with Anna… It was supposed to be our own Winter Wonderland Adventure…" a young princess thought as she raced with her parents to meet with the rock trolls. "Why did it have to turn out this way… Anna…" She would have cried, but she was too scared of what might have happened to her beloved younger sister Anna if she didn't control herself right now.

The family finally made it to the Troll Grove after a little time and immediately the creatures rolled up to the King of Arendelle as he pleaded for their help.

"Let me see her," an elderly troll said. The King of Arendelle handed over his youngest daughter for the troll's inspection. The troll placed his rocky hand over Anna's head near the base of her hair delicately.

"Born with the powers or cursed?" the troll causally asked. Elsa tensed at his words. She hadn't really put much thought into where her powers came from really. They were just a part of her somehow.

"Born," The king replied. Elsa felt a little relieved hearing that, but only a little. It didn't matter where her powers came from, she had still hurt her sister. "And they're growing stronger," her father added.

The troll nodded and said, "You are lucky. I can save her," the elder troll said. The whole family felt relieved as he continued to speak, "The magic struck her mind. If it struck her heart, then it would be a different matter. However, the head can be… persuaded."

Elsa again felt a little scared of herself hearing his words. The elder troll continued, "I will remove all memory of magic from her head." He started waving his hand over Anna.

"You mean Anna won't remember anything?" Elsa asked in fear. Magic was part of her. Was the troll going to remove all memory of her as well? Would she never know her sister again?

Her mother gave her daughter a sad expression as she said, "It's for the best, honey." Elsa's heart sank at those words. She feared her mother was saying it was best Anna never knew her after tonight.

The troll looked to the family with critical eyes as he started working his magic. "I will leave the fun." This family looked like it was going to unfortunately be difficult for him. They were all panicking at the moment. He hoped they would listen to him and heed his words.

Images of Anna's memories formed above her head. Elsa relaxed as the memories still showed her and Anna together happy and having fun. It was just different. They were outside in the snow instead of in one of the great halls of the castle. Elsa still felt fearful of her powers never the less.

Once the magic was complete, the troll spoke to her directly. "Elsa. Your powers will grow strong. There is beauty in them."

Elsa relaxed as she watched the display he gave her. She watched as a figure made snow while other figures danced in happiness.

"But there is also great danger!" The display turned dark as the show exploded and she heard a scream of terror. Elsa clenched her hand placed on her heart.

"You must learn to control them. Fear will be your enemy," the troll finished as he looked Elsa right in the eyes. Elsa felt a little uneasy under his gaze not sure what to make of his warning.

"We'll protect her. She can learn to control it. I'm sure. Until then we will close the gates. Cut the staff. Limit her contact with people. Keep her powers hidden… even from Anna," the King said as they made ready to leave.

Elsa didn't like this one bit at all. She knew she deserved to be punished for what she did to Anna, but she feared this punishment would really hurt her sister along with herself. "I'm just a child… I don't really know better…" she thought darkly as she was ready to resign to what her father said.

The troll gave a frown. He didn't like where this was going. Maybe he was too extreme in his warning. "Those are decent precautions…" he started as the Royal family stopped mid step and looked to him.

He spoke again, "However… I think you may have misunderstood my warning. Complete Isolation is not the answer. Keeping these two sisters, with such a strong bond already, completely separate will only make things worse."

The royal family walked back over to him eager to listen. "When I said fear would be her enemy. I meant fear of herself and her powers and letting that fear control her. I guess I should have better explained my warning. It is her own fear that will be a great danger."

The royal family looked to each other as Elsa thought maybe there would be some hope after all. The Queen next spoke, "What do you recommend, Grand Pabbie?"

Grand Pabbie, the leader of the rock trolls, scratched his chin in thought before responding. "I think you should start young Elsa's Queen training very soon." The family looked to him with frowns.

"Her situation is different from your mother's, my Queen. Her powers have already awakened." He looked to Elsa as he spoke again. "When the time comes, you will receive a letter from a famed school in the magical world. The headmaster will know your royal heritage, but not of your ice powers. Your powers should be kept secret, so others won't try to use you for their own ends."

He looked to the parents now. "Also, with those young like your daughter here their powers can sometimes overflow due to emotion. Emotions shouldn't be completely rid of, but they should be controlled. The queen training will help with this. Let her still visit with her sister, maybe they should be separated to a degree, however not completely."

"Then we will still keep the castle gates closed. Limit contact with others for now. And keep the powers a secret, but at the same time..." The King said as he looked to his oldest daughter. He gave her a small smile, "We will allow you and Anna to roam the castle and spend time with each other." The Queen and the elder troll nodded to this in agreement and the royal family left the grove.

Elsa felt relieved as they made their way back to the castle at an easier pace. Anna and she wouldn't have to stay completely away from each other. Elsa wasn't happy about having to start her Queen training early, but if the trolls said it would work she was sure it would. If it meant she would still get to be with her sister as well, then there wasn't much chance she wouldn't go through with this plan.

She still wondered though, "What did he mean about, Grandma?" Her grandmother had died before she was born. She had seen pictures and heard stories from her parents about her though. However none of those stories mentioned her grandma having powers.

"The powers you have are part of the Royal Arendelle bloodline, Elsa. However, they don't always awaken, so they are usually kept secret," her mother answered.

"Your Grandmother had ice powers as well, Elsa. Unlike you, her powers didn't awaken until much later in her life," her father added.

"Because of the powers running in the family, even if they don't always surface, Arendelle's Royal training focuses more on meditation and controlling emotions." Her mother gave a sigh, "Until tonight we didn't think it was something we really needed to practice with you yet, Elsa."

Her father gave a sigh as well, "We wanted you and Anna to have as much of a childhood as you two could before getting into it. You two are both very well behaved children, even if your sister is much more… rambunctious."

"You two have never really had any outbursts of emotions. We also didn't really know emotions could cause you to lose control of your powers. Like we said your grandmother's awakened later in her life. I am just a carrier of the powers like all females in our family. Mine haven't awakened and I doubt they will," her mother said.

The queen then gave a small smile, "I always thought the training was needlessly extra rigid, myself. After hearing Grand Pabbie's warning and his clarification, it all makes much more sense now."

The mother then ran her hand through Elsa's hair and gave her daughter a hug as she said, "I'm sorry I couldn't have been more help, dear."

Elsa gave her parents a reassuring smile as she said, "I'm just glad Anna's going to be alright and I'm not going to be completely locked away from her. Even if I have to keep these powers a secret from her, it doesn't matter so long as I have my sister in my life."

The King gave a tired smile as he said, "I get the feeling you will be one of Arendelle's greatest rulers when the time comes, Elsa. I'm even surer you'll learn to control your powers. One day in the future I'm sure you'll be able to share your powers with Anna once again."

"It just might not be until she remembers about your magic. Even if the mind can be 'persuaded', I'm not sure it can be completely rewritten with just this one spell," her mother said to her.

"I'm more curious about this school he mentioned. Do you know anything about it, Honey?" the king asked as they made their way back to the castle.

The Queen was lost in thought for a few seconds as she tried to remember details about it. "I seem to remember reading something about a Hogwarts School for Witchcraft and Wizardry. It was under the education part of the Queenly Education Annuals. When a daughter or son of Arendelle awakens their powers at a young enough age, they attend under the name of Evergreen."

"When does this happen and at what age?" the king asked his wife. Elsa was just listening to the adults talk. She found that to be a good way to learn many things. Just let the adults talk and you will hear them say all sorts of things they otherwise wouldn't.

"Around the age of eleven, I was going to tell you when Elsa was closer to that age. I didn't want you to ask too many questions about magic and such with some of our guests," the queen answered.

"Wait a minute?" Elsa finally spoke out. Her parents were a little startled by her sudden interruption. "You mean to tell me there are others with magic? And you know about them? Why do I need to hide my powers if others can use magic anyways?"

Both parents gave knowing sighs. Her father started. "Yes. There is magic in the world, but it doesn't usually work in Arendelle. Our land is rich in ancient magic. It along with its people have developed a strong resistance to it if not a full on immunity."

"Our bloodline's powers, however, are an exception along with those who awaken them. You will find yourself resistant to hostel magic. I don't know how that is the case, but if what I have read from the protected histories is at all slightly correct. This is the case with every person in our family who awakens what we call 'The Gift'," her mother picked up and continued.

The Queen took in a deep breath and let it out, "The powers that come with this awakening are not the same as what other magic users have. It is far stronger. It is much more natural in both senses. Powers such as yours would be highly sought after by those who wished to have more power their selves. They would do whatever they could to gain them and have you use them on their behalf. Be extra careful who you let know about your powers, Elsa."

Her father then started again, "You don't have to let anyone know apart from us if you wish it. The choice is ultimately yours, Elsa. We just hope you will be careful."

"Also realize that as Crown Princess and future Queen of Arendelle you have to think of not only what is best for you, but our country as well," her mother added.

"We're home now. Let's all get to bed. Anna probably won't wake up until late tomorrow thanks to Grand Pabbie's magic," the King said. Elsa gave a yawn followed by her mom. The king gave a chuckle at how similarly his wife and oldest daughter yawned. "I think we're all ready for some sleep," he concluded.

"Actually," the Queen started. "It might be best if we have Anna and Elsa use separate bedrooms from now on."

Elsa's eyes widened. "Are we not going to be able to see each other anymore?!" She asked in panic.

Her mother wrapped her oldest in a hug. "No, Elsa. Just separate bedrooms. With your powers having to be kept secret and starting your Queen training soon. It will be for the best. You can relax a little more when you are in your room alone and you will be able to study uninterrupted when you want."

Elsa frowned but nodded her head in agreement. She didn't like the idea. Her and Anna had shared a bedroom since forever, or well since Anna stopped needing a crib. She also knew her mother was right that it would be for the best, even if she wasn't happy about it.

Anna was placed in her bed for the night. Their mother watched over Anna while their dad gathered up servants to help with moving Elsa's stuff into a new room. Elsa sat on a couch and watched with tired wonderment at how quickly and quietly the servants managed to move her stuff.

The blonde princess gave yet another mighty yawn for her small size when her father returned and said the new room was ready. Elsa gave a frown to what used to be her side of the room as she sleepily followed her parents to her new one. She was glad it at least wasn't too far from the old room. She might have cried at the fact she no longer shared a room with Anna as she laid down and was tucked into her bed, but she was too exhausted emotionally and physically from the night's events.

In the morning, she would start to fear what Anna would think after everything. She would then worry, not for the last time, what would happen if her sister again found out about her magic. Would it not matter? Would her sister suddenly collapse and the magic return that almost killed her? It wouldn't be easy keeping things from Anna, but it would be necessary for them both Elsa was sure. She gave one more yawn and closed her eyes as she lay in her bed.

A/N: This is going to be a Harry Potter and Frozen cross over. I have tried to modernize Arendelle as a financial powerhouse nation and have changed some other things. It will take a little time until Harry Potter and the others come into play with the story, but they will be a big part of it. Also, this won't be a Dumbledore is secretly evil story either. I don't plan on bashing Ron either.
