All you need is love [An Elsa and Merida love story]

Elsa

My sister Anna walks into the room dressed in a beautiful white gown.
   The sleeves of her dress stretched outwards and wrapped around her arm like it had been a part of her. 
   The decorations of the fabric formed the shape of a flower. It connected into a V around her neck. The bottom half stretched out into a hoop skirt, she looked as beautiful ever. She reminded me of Mother in her wedding photo.
   "This was our mother's wedding dress," smiled Anna.
"You look beautiful," I said.
   If only mother were here to see this." Anna spun around.
"Mother would have been proud" I held Anna's shoulder. Anna opens her mouth about to say something. I let go of her as soon as I hear a thud on the door. Five guards march inside.
  "Your highness." A guard bowed, "We're under attack." The other guard interrupted.
   "Wait. What!" Anna ran towards the window her wedding dress flopping along as she ran. I followed her.
I see a woman throwing objects around the kingdom. They looked like ... flames?
   "Why is she doing this?" Anna screamed.
"Guards! Send in the troops!"  I gestured towards my soldiers. They nodded then ran through the doorway.
  "Stay inside," I told Anna and ran alongside with my guards.
"Elsa I'm coming too, she could mean no harm!" Anna's voice echoed from behind me.     "No! Anna your staying inside it's too dangerous, for you," I said.
      The villages and houses were on fire. my kingdom was no longer sparkling snow and ice that it had been a minute ago.
   Villagers screamed and ran like a swarm of bees.
  "Queen Elsa" a little girl held my hand. "Please help us, it's a witch!"' the little girl hugged me then ran off to her mother.
    I waved my hands around my periphery and sent snow and ice to circle the flames - cooling it down
   "OWW that hurt!" echoed a voice nearby. I turned around and saw her. The girl in the red dress. She had Long black hair, pale skin, deep brown eyes. She looked no older than I was; 20-25 years old?
     "Who are you? And why are you trying to destroy my home."  I demanded. The woman smiled and drew flames from one hand.   Then I realised the flames were coming out of her, from her. She was the polar opposite of my own powers.
"You're... like me!" I gasped.
   "Not exactly" the woman said.
"Who are you?!" I questioned.
      "My name is Theodora," the woman said, staring at me like I was a pile of mud.
"Why are you doing this?" I asked.
  Flames ignited around her body as she blasted heat through out my body. I caught the flames with snow I had summoned and pushed power back towards her. I could feel the heat burning into my flesh as the fire and snow connected.  Theodora fell back, her flames dying out.
"Ill be back Elsa! You'll see. I will be back for revenge!" The girl spat, turned into a halo of flames then vanished in a wisp of smoke.
