In Arendelle, the Aurora Borealis glowed in the sky. No one was awake to see it. Well, someone was awake…

"Elsa" whispered Anna urgently, clambering onto her sister's bed. "Hmmmm." replied Elsa sleepily. "Let's go play."

"Go back to sleep, Anna."

"But the sky's awake, so I'm awake, so we have to play." explained Anna in a reasonable tone.

"Go play by yourself." grumbled Elsa as she shoved Anna off the bed.

"Hmph" said Anna in an injured tone. Then her expression brightened. She climbed up again. "Do you wanna build a snowman?" she asked, pulling Elsa's eyelid open. Elsa opened her other eyelid and smiled.

Anna giggled excitedly as they ran down the stairs to the ballroom. "Hurry, hurry!" she implored her older sister. "Shhh" cautioned Elsa, who was making at least as much noise as Anna. They skidded into the ballroom and closed the elaborate double doors.

"Are you ready?" asked Anna, and promptly sent a glowing ball into the air. It exploded into snow, and soon, the ballroom was unrecognizable. Anna stomped her foot, and ice spread from the point of contact.

"Hi, I'm Olaf, and I like warm hugs!" said Elsa, hiding behind a snowman with a large carrot nose .Anna laughed. "I love you, Olaf!" she hugged the snowman. They skated around the room, powered by Anna's snow.

"Jump, Elsa!" shouted Anna. It was a trick they'd been practicing for ages. Elsa jumped off a snow drift, and Anna caught her in another. Elsa began jumping faster and faster, and Anna practically had to turn pirouettes to keep up.

Suddenly, Anna slipped on the ice. She fell, her short blond pigtails swinging. She pushed herself into a half sitting position, just in time to see Elsa spin through the air. "Elsa!" she cried, shooting a blast of her snow magic.

It hit the crown princess in the head. Elsa crashed to the ground. Anna ran towards her sister's limp form."Mama! Papa!" she cried, cradling the unconscious Elsa's head in her lap.
