Screams echoed thorough the valley as the dragon swooped down for another attack. The townspeople were running everywhere, desperately trying to find a path to the castle.

Anna ran through the corridors urgently trying to find Elsa. He was back. The dragon determined to claim Arendelle for his own. The sound of shouts and chaos could be heard outside. The castle gates had been opened and more and more people were flooding in by the second, trying to get to safety. Suddenly, a ball of flame flew through the window. Anna shrieked and fell to the floor. She looked up cautiously and saw that the tapestry on the wall was ablaze. Before the fire had the chance to spread however, a blast of ice extinguished it. Elsa ran towards her sister and collapsed to her knees in front of her.

"Anna are you alright?"

"I think so, argh" she yelped in pain as she moved her arm. Elsa quickly looked at it. The heat had burned through her sleeve and left a large burn on her forearm.

"You've got quite a bad burn" Elsa said, "But this won't hurt a bit". Elsa made her hand go as cold as possible and pressed it onto Anna's skin.

"Ouch!" Anna yelled. Elsa smirked slightly at her.

"I lied"

After a few minutes, Elsa took her hand away and helped Anna to her feet. They both immediately walked to the broken window and looked out over Arendelle. The dragon was making his way towards the castle courtyard. Elsa turned to Anna.

"Get everyone inside the castle and keep them safe"

Anna nodded to show she'd understood her sister's instructions. Elsa turned away from the window and began running down the corridor towards her bedroom. Anna called after her.

"Where are you going?"

"I've got a date with a dragon" Elsa called back.

The platinum blonde entered her room and scanned it quickly for what she was looking for. A picture of her, Anna and their parents. She looked at it for a moment before moving it aside to reveal a long case. Elsa picked it up and carried it over to her bed and opened it. Inside was a bow and a quiver of arrows. She hadn't used these since the last time the dragon had attacked about a year ago. Although Elsa had her winter powers, she still liked to carry a weapon to defend her kingdom. She was still terrified of losing control and endangering everyone she cared about. This way, Elsa had a choice over using magic or not. She placed the quiver on her back, picked up the bow and walked out onto her balcony.

Anna made her way towards the front doors of the castle.

"Open the doors by order of the Queen" Anna commanded the guards. They nodded and soon Anna was faced with a very large crowed of frightened people.

"Everybody, please make your way to the Great Hall!" she shouted. The citizens of Arendelle fled inside the castle. Through all the hubbub, Anna spotted Elsa stood on her balcony. She had fitted her bow with an arrow and was now tracking the dragon, waiting for it to fly into her target range. Anna knew that Elsa would defend Arendelle to her last breath and this worried her. After being shut out for thirteen years, Anna didn't want to lose her sister again. The strawberry blonde made her way over to the guard on the door.

"It is our duty to keep these people safe. When that dragon comes to the castle, shut the doors and defend them, no matter what".

"I understand Princess Anna" the guard responded. And with that last comment, Anna ran towards the armoury.

The dragon was getting closer and closer. Elsa didn't take her eyes off it. His stomach started to glow orange and the Queen knew what that meant. Quickly, she froze the arrow and fired. It hit its target and cancelled out the would be flames. Elsa smiled. But that smile disappeared when she realised what she'd done. She may have just stopped a blazing inferno but she had alerted the dragon to her whereabouts and he was now flying straight for her.

"Oh shoot" Elsa thought to herself. She quickly reloaded her bow but before Elsa could aim and fire, the dragon's tail hit the balcony causing Elsa to fall over. The dragon heated up its breath again, preparing to strike. Elsa had no time recover before the dragon let lose its fire of fury. She closed her eyes, preparing for the worst but to her surprise, nothing happened. Elsa slowly opened her eyes to see her sister crouched in front of her, a shield blocking the flame from both of them.

"Elsa, a little help please!" Anna said. Coming back to reality, Elsa quickly leaned out from beside her sister and fired an ice blast at the dragon. It roared and fell backwards, allowing Anna and Elsa to recover.

"Thanks Anna" Elsa said.

"No problem" Anna replied.

"Hold on, why are you up here with me? I told you to protect the townspeople"

"I've informed the guards, they're more than capable to look after them and besides, I'm not letting you attack a massive dragon by yourself and by helping you, I am protecting the people"

Elsa had to admit that Anna had a fair point. The dragon was beginning thaw and preparing for another attack. The platinum blonde then had an idea.

"Right Anna, when I say, jump onto his back"

"What!?" Anna exclaimed. Ignoring her sister, Elsa continued to speak.

"I'm going to freeze your sword and then you jump on his back and stab him!"

The dragon was approaching the balcony, ready for round two. Elsa grabbed her bow and fitted another arrow. When he was close enough, she released it. The arrow pierced through the dragon's foot, securing him to the railing. He roared in pain and began to pull the arrow out. Elsa fired again and again, trying to keep him in place.

"Now Anna!" Elsa yelled. Anna stood there, her shield in one hand and her frozen sword in the other.

"Anna! You have to do this!" Elsa yelled again, realising her sister wasn't moving. Anna knew Elsa was right. She had to do this. To protect Arendelle. To protect her sister. She ran towards the dragon and jumped. Dropping her shield, she grabbed onto one of the dragon's spines and swung herself up onto its back. Taking a deep breath, she held her sword with two hands and plunged it into the dragon's hide. He threw is head back with a loud roar as the ice seeped into the wound. Anna was knocked off his back and began to fall towards the stone paving of the courtyard.

"Anna!" Elsa saw her sister falling and quickly threw her hands out. A snow bank appeared below Anna to break her fall, her sword clattering beside her. They both looked up to the sky as the dragon flew back towards the North Mountain. However, the sisters knew he would be back.

Had this idea after seeing the Desolation Of Smaug. I hope I shall be able to do regular updates. Happy New Year! :D
