I Am Not Elsa
Disclaimer: I don't own Narnia or Frozen.
I paused outside the small, rundown shack. Once I enter, I can never go back. I then remembered that it was growing harder to control Arendelle, as it had been called in the past, with only my ice powers and other small spells. Resolved, I entered the hovel and learned the word that, if spoken with the right ceremonies, would destroy everyone except the speaker. Once I had learned it, as I left, I decimated the cabin so that no one else could learn this magic weapon.
When I returned home, Anna, along with half of the army, was gone. All that was left was a note, which read: You've changed, Elsa, and not for the better. I wish my sister would come back. But I don't think she will and so I'm leaving, but I will return, and I will take the throne to protect our people. Be ready, sister. I crushed the paper in my hand. "Oh, I'll be ready. You can count on that."
I spent the next several months preparing my armies for war. I knew Anna would return because she had promised she would. I didn't even care that I would be fighting my own sister. She was standing in my way and I would win the ensuing battle. No matter what it took.
My sister came. I was ready. We agreed to use no magic, though I did not care about any such agreement. If magic was the only way to win, I would use it.
My men fought. They fought until the last one of them was dead. As my sister reached the peak from which I was watching, she said, "Victory."
I waited until I could see her face through the blizzard I had made. "Yes, victory, but not yours." I spoke the word. In that moment, I was the only living thing under the red sun. As I joined my ancestors in slumber until the bell should be rung and I was awakened, one last thought entered my mind. I am not Elsa.
I am Jadis.
