Prologue: Three Sisters and the Cost of Magic

In the kingdom of Arendelle, there were three sisters; Brielle, Elsa, and Anna. They may have been princesses, but they were first and foremost sisters. Even though both Brielle and Elsa had magic, they were still able to have fun through all the fear and uncertainty.

Elsa had the power to manipulate ice and snow. While Brielle had the power of fire. Although they were supposed polar opposites, they seemed to be the closest of the three, but then again, all three were close no matter what.

Elsa's powers appeared first. When Elsa was 6 years-old, Brielle was 5, and Anna was 3, Elsa started using her powers for fun. This worried their parents greatly. They warned Elsa to be careful with her powers. Elsa promised that she would, but that was easier said than done sometimes.

Brielle had yet to reveal her powers to her sisters, she was too afraid of what her sisters would think. Would they be afraid of her? But Elsa had powers too, so of all people she would understand. Would she understand? But their powers were complete opposites. Besides, fire is more dangerous than snow or ice, or at least that's what she thought. The last thing she'd ever want to happen was hurt her sisters. She loved her sisters too dearly to take that chance.

So, Brielle decided to keep her powers a secret from her sisters, and their parents had seemed to have already agreed to that. Brielle was surprised to find that she had little trouble control of her powers. That fact gave her comfort, and lessened the fear of hurting her sisters, but she still couldn't bring herself to let her guard down. Brielle sometimes felt that she was the real older sister because she had thoughts and feelings that seemed beyond her young age. Although she was one year older, Elsa didn't experience the nagging fear of hurting the people she loved, Or at least…not yet

Two years later, Elsa and Brielle were woken up one night by the shaking of a very persistent Anna. Elsa and Brielle shared the same room, because of their parents desire to keep Anna separated from her sister's magic. And as long as Brielle and Elsa kept their powers relatively under control, it didn't seem to cause any problems. They were pretty sure that Brielle and Elsa wouldn't have a problem with it, considering how close they had always been, they didn't.

Anna had gotten into the habit of sneaking into her sisters' when she wanted something. Whether it was comfort from a nightmare, or many other things.

"Elsa, Brielle," Anna whispered softly, "Wake up,"

Elsa moaned, "Anna, go back to bed."

"Yeah," Brielle added groggily, "and besides, it's late."

The two sisters turned over and snuggled back into their covers, hopping they would fall back to sleep.

Anna climbed up on Elsa's bed and whispered in her ear, "Do you wanna build a snowman?"

Elsa and Brielle's eyes snapped open at this. They quiet got out of their beds and crept down the many hallways, careful not to make any noise. After a few minutes of silence and anticipation, they finally reach their destination, the ballroom.

"You guys ready?" Elsa asked, a small snowflake hovered above her palm.

Her sisters nodded eagerly as Elsa turned the ballroom into an ice rink-like wonderland. This was a special time for them. This was the one time when they could be together in the snow without the worried yet watchful eyes of their parents.

They immediately began constructing their snowman, and in a short time they had built a cute snowman with an oval-shaped head.

"Hi. My name is Olaf, and I like warm hugs," Anna said in somewhat deep voice. This produced a happy laugh from all three girls.

Elsa then began to make ice platforms for the girls to jump on. This was something Anna always enjoyed, although her sisters didn't understand why.

Brielle followed behind Anna as the platforms came higher off the ground, wanting to be there in case something went wrong.

As Anna began to run faster, Brielle began to fall further and further behind her sister, "Anna slow down. I can't keep up with you."

"Yeah, you're going too fast," Elsa said, somewhat panicky, just barely able to keep up with her sister.

Anna wouldn't listen, and ran forward before Elsa was able to create another platform, and began to fall.

"Anna!" he sisters exclaimed.

Elsa shot a line of her power towards Anna, hopping to stop Anna from falling, only to have it hit her in the head. Elsa and Brielle ran to Anna as she fell to the ground. They knelt beside their sister, her eyes were closed, and she felt ice cold to the touch. This terrified Elsa. What had she done? She hadn't meant to hurt her, and now she was fearing for her sister's life.

"Anna, Anna. Please wake up," Brielle pleaded.

"We're right here," Elsa said softly.

Just then, their parents appeared in the doorway of the ballroom, shocked expressions on their faces.

"Elsa, what have you done?!" their father exclaimed, "We told you to be careful."

"I know, but it was just an accident," Elsa replied, scared for more reasons than one.

"I tried to protect her, Daddy," Brielle added, hopping to soothe some of her parents' anger at Elsa.

"I'm sure you did, Brielle," their father replied.

Their mother ran toward Anna and picked her up, "She's ice cold."

"I know just where we need to go," the king said.

The royal family headed deep into the forest before stopping in a clearing filled with rocks.

"Please, my daughter needs help," the king called out.

The family stood in silence and waited for something to happen. Just then, the rocks began to move, and they suddenly became trolls.

"Hey look, it's the king," a troll said

An old-looking troll made his way to the family and looked at Anna, "She was struck on the head, which is easier to fix. You're lucky it didn't hit her heart."

"I can heal her, but I will erase her memories of magic, and just leave the happy parts," the troll said.

So that meant Anna would have no memory of Elsa's magic. Brielle didn't know how she should react to this, so she just stayed silent.

"It would be best to remove all magic," the troll continued.

Brielle felt sorry for Elsa, that meant she would have to hide her powers from Anna, and she knew that meant her too.

He then turned to look at Elsa and Brielle, "Both of you have extraordinary gifts. Gifts that hold great beauty, and great danger. If fear ever takes hold of you, the harder they will be to control. And the more your powers mature, the harder it will be to counteract each other."

Elsa shot Brielle a questioning look. Anything that Brielle had planned to say froze in her throat. She knew it would've come out at some point. She supposed it was better it came out now. Her only hope was that Elsa would forget over time. Luckily there never were specifics about her powers.

The girls nodded in understanding. Anna finally opened her eyes, which gave them unspeakable amounts of relief. They royal family thanked the trolls and headed back home. Brielle and Elsa were somewhat relieved that Anna wouldn't remember what had happened, but also sad that she would never truly remember all the fun that they had together.

Brielle was secretly happy that she would never have to fear telling her sisters about her powers. Yet, she was completely unaware of the consequences that came with secrecy. But she would soon find out.
