Anna stormed around the upper floor of her palace, smashing pillars and regrowing them. Olaf tried to calm her , most of his methods involved summer. Not good for a raging ice princess.

Anna calmed down by herself eventually. She descended the stairs.

" Elsa," she called." I'm...I'm sorry."

Silence greeted her.

"Elsa!" she shouted, panicking. Elsa had always been there for her. Now...

She slid down the banister and blasted the door open.

There in the snow lay a set of footprints, leading down the mountain.

"Oh no." she whispered." What have I done?"

Elsa struggled through a snowdrift. Her bun had come undone and her braid was threatening to do so. She glumly concluded that a coronation gown was not the best thing to wade through snow in.

An ominous creaking noise. She looked up. A pile of snow slid off a branch.

The search party floundered around in the snow. They hadn't even managed to get to the foot of the mountain. They carried a jumble of weapons, no one knew why, including the bearers. They looked to the sea.

A forest of masts moved steadily towards Arendelle. They were still in the distance, but they were moving fast with a strong following wind. The citizens of Arendelle went about their business and prayed for the Queen to return.

The Queen of Arendelle was currently thinking a lot of swear words. Her dress hadn't frozen, being ice. But her feet were cold. If only she hadn't gotten lost... No. Queens did not get lost. Queens always knew where they were. It was everything else that didn't know where they were. If only she hadn't left Anna. If only they hadn't quarrelled.

Anna was sledding. She had made an ice sled. Olaf was sliding along on his, for want of a better word, belly. She clenched her teeth and concentrated on not creating a snowstorm. She needed to follow those tracks.

Elsa looked seaward. What she saw made her roll several feet down the mountain. A fleet bearing the crest of Hammerfest. Not friendly. Not if there are cannons pointing at the shore you're heading for. She had to assemble the army. Either word had gotten out that the royalty were missing or Hammerfest thought that with a Queen on the throne, especially a new one, Arendelle wouldn't stand a chance. Whatever the case, Arendelle was in danger. She ran.

Anna caught sight of Elsa running through the trees. She had cheated considerably, using her snow powers to move the sled. Her heart sank. Would Elsa forgive her? Only one way to find out. "See you later Olaf!" She shouted, pushing her sled forwards.

Tree ahead. Brakes. Where are the brakes? No brakes. Uh oh. Anna panicked, lost her head and attempted to use a blast of her powers as brakes.

That's when it happened.

Ana misfired, hitting Elsa. Elsa crumpled to the ground. The search party burst through the trees ahead.

"Witch!" spat one of them, raising a crossbow.

"No." said Elsa, struggling to her feet. I.. I'm fine. Protect Arendelle. Go! Hold the shoreline. Don't attack until Hammerfest does. That is my command. I will not require an escort."

The men left. Elsa turned to Anna, her face pale.

"I'm sorry, Elsa." whimpered Anna. "Did.. did I.."

"I'm fine." repeated Elsa. "What should we do about this invading army?"

A grin spread across Anna's face. Her mood changes were fast. "I have an idea..." she told Elsa her plan. Elsa's eyes lit up. They went down the mountain together.

A lock of Elsa's hair turned white. She was so cold... She knew Anna had hit her. She just hoped she could save her sister and the kingdom.

I know there's a bit of Brave in it. Just not enough to make it a crossover, OK?
