A/N: An idea that popped into my head and wouldn't get out. So here goes...the really short prologue of my first Frozen fanfic, of the movie I fell in love with three days ago.


13 years ago...

Eight-year-old Elsa knew herself to be a light sleeper, so it wasn't a surprise to her when she woke up in the middle of the night. What surprised her was the funny smell of their room. It smelt like smoke...like of something burning.

Her eyes flew open, jerking awake in her bed and turning to face the source.

Opposite her, small Anna was asleep in her bed, tucked snugly beneath her crimson covers with one hand flung out to the side. Her face was illuminated by an orange glow, which Elsa realized came from the burning nightstand beside, encased in a flurry of crackling flames. Her heart jumped to her throat.

"Anna!" she screamed, instinctively shooting a jet of ice at the white hot fire.

That night, Anna wasn't harmed, and the fire had been doused, but not the fear in Elsa's heart. It was a matter of restless hours before Elsa could finally calm down and get some shuteye, so it was an irk to have the bubbly Anna wake her after only another three hours.

"Elsa! Wake up!" hollered her sister, bouncing on her bed. "Wake up, wake up!"

"It's too early," she groaned, not opening her eyes. "Go back to sleep, Anna." However, instead of feeling the weight leave her bed, she felt Anna shift until she was sprawled all over her elder sister.

"I just can't!" whined her sister. "The sky's awake, so I'm awake, so we have to play!" From the sound of her tone, Anna showed no sign of knowing how close she'd been to death last night. Elsa suppressed a shudder at the mention of the sky. It reminded her of the sun, and the sun reminded her of fire.

"Go play by yourself," she mumbled, nudging the five-year-old off onto the floor.

There was a thump, and for a moment, she almost expected her sister to release the tears. But she knew that wasn't Anna's thing - to cry - not when her personality was akin to a burst of golden sunshine. So it wasn't unexpected when the jovial child bounced back upon her bed.

This time Anna whispered, but the excitement was still there. "Do you wanna build a snowman?"

Had Elsa known what was coming, she wouldn't have opened her eyes.
