Chapter 1- The night when everything would change.

It was a winter's night in the Arendelle castle. The aurora borealis shone in the night sky. At this hour everyone in the kingdom should have been tucked up in bed, but that was not the case for the two princesses. In one of the castle's largest bedrooms Anna, the youngest of the princesses, had given up on trying to sleep and snuck up to her sister's bed.

"Psst Elsa!" Anna whispered, jumping up on the side of the bed. Her sister did not move."Psst Elsa!" Elsa still did not awaken. Anna decided to take the direct approach. She jumped onto the bed with her tiny legs and shook her sister "WAKE UP, WAKE UP!"

"Go back to sleep Anna." Elsa murmured drowsily.

"I can't sleep, the sky's awake, so I'm awake," the young princess pleaded, "so we gotta play!"

"Go play by yourself." Elsa said, pushing Anna off the bed. Anna sat on the floor and wracked her brains for a plan. Her entire body tensed with excitement as she finally came up with an idea. She climbed up onto the bed and opened her older sister's eye.

"D'you wanna build a snowman?" Both of Elsa's eyes opened.

"You win."

Soon enough, the two young princesses were out of their beds and sneaking their way down to the royal ballroom.

"Remember, we have to be quiet if we do this." Elsa instructed solemnly. She knew they would both be in trouble for this, but she loved making her little sister happy, especially when she used her magic. "Are you ready?" Elsa asked as she held out her hands. Anna nodded playfully and Elsa held out her hands. Suddenly, a shiver ran up her spine and she felt as if something was about to go terribly wrong.

"Elsa?" Anna asked curiously, "Why aren't you doing the magic? Are you ok?"

"I'm fine." Elsa replied, taking a deep breath. She held out her hands to make a ball of ice, but she was interrupted. A blinding flash of light filled her eyes. An older version of herself was next to a door, crying. As quickly as it came the vision went. Elsa saw Anna in front of her, cheering her on to "do the magic". Elsa smiled and shot the ice ball that was now in her hands into the air, letting it explode into a shower of snow. Anna giggled and danced around, her hands trying to catch the snowflakes as they fell.

"It's so pretty." Elsa smiled. Then another flash. This time, an older Anna danced around the halls of the castle. Her vision returned to normal once again and Elsa still saw her little sister playing with the snow she made. Why is this happening? She thought. Is it just because I'm tired?

Elsa stamped her foot on the floor, turning it into a miniature ice rink for herself and Anna. Yet another vision filled her sight, this time she was running across the fjord while freezing the surface. Shaking herself back to normal, Elsa returned to playing with her sister. The next few minutes consisted of the princesses gliding on skates made of ice, ensuing snowball fights (which Elsa let Anna win) and making snow angels. Again the sister's playtime was interrupted. All Elsa saw was white. Blinding white. She was running, but from what? Or, from whom?She took a deep breath and calmed down. She didn't know what these visions were but they were not going let her ruin her and her sister's playtime. She created a big pile of snow and made a crude face out of it. Stealing some twigs from a nearby plant, she stuck them in the sides of the snowman.

"Hey I'm Olaf and I like warm hugs." Elsa said in a goofy voice, but as she did so she saw her creation eating … cake? Elsa returned from this vision to see Anna staring back at her with her big beady eyes, hugging the snowman.

"He's so fluffy, thank you Elsa." Anna giggled. Elsa's cheeks turned a rosy pink. She always loved it when Anna complimented her. Ever since the day she was born, Elsa had been there to protect and care for Anna, even more so than their mother and father. She had always felt a special connection with Anna that she knew no one else shared, and deep in Anna's little heart, she felt it too. "Let's play some more!" Anna cheered as she ran over to a big pile of snow. "Try to catch me!" Anna jumped off the pile into the air, landing onto a higher snow pile made by Elsa.

"Hold still!" Elsa cried as Anna leapt higher and higher. Elsa struggled to keep the platforms underneath her sister. Soon Anna was near the ceiling, Elsa knew she had to keep her sister safe. She reached out her hand to fire a burst of ice to catch her, but before she could do so, a vision flashed in her mind again. This time however, she saw herself, the same age she currently was. She was cradling Anna's lifeless body, a white streak in her sister's hair.

"Don't fire that ice blast Elsa," A voice said in her mind "Fire it at the floor beneath Anna". Elsa did not know who that voice was but her natural instinct was to trust it. As soon as her sight returned to normal, she fired her ice blast into a cushion of snow on the floor. Anna landed into it with a soft thud. Elsa rushed to her sister's side. Please let her be alright she prayed silently,I don't know what I would do if she wasn't. "Anna?" Elsa quietly spoke, shaking her sister's body.

"Looks like you win Elsa." Anna weakly giggled, "you caught me."

"Oh Anna." Elsa said relieved, hugging her baby sister tightly.

"You're my knight in shining armor." Anna declared, hugging her sister back.

Elsa giggled and slightly teared up, part of her felt such joy in seeing her little sister, her best friend safe. However this joy was sadly interrupted.

"Elsa? Anna? What have you been doing?" Their father demanded, entering the room with their mother.

"It's all my fault papa." Anna replied, taking responsibility, "I got Elsa to make the snow so we could play, I'm sorry." Their father smiled as he hugged his youngest daughter.

"It's alright Anna, but you and Elsa will have to clean up this mess."

"We know papa."

Elsa butted in, "we're sorry." Elsa whisked her hands, and the snow melted away.

"Now you two get back to bed." Their mother said, "beautiful princesses need their beauty sleep."

"Ok!" Anna replied excitedly, grabbing Elsa's hand. "C'mon Elsa, let's go back to sleep and be pretty!"

"I don't think that's what mama meant." Elsa laughed as Anna led them back to their room.

As the two girls entered their beds, Anna gave Elsa a cute little smile. "Thanks for saving me."

"Thanks for sticking up for us." Elsa thanked her sister, her cheeks rosy again.

"It's ok, I didn't wanna have mama and papa shout at us and make you cry."

Anna squeaked in her little voice.

Elsa blushed again as she curled up under her blankets.

"I love you Elsa." Anna yawned as she fell into a deep sleep. Elsa smiled and responded.

"I love you too Anna".
