Arendelle put under Eternal Winter
Queen Elsa's coronation goes terribly wrong after she uses her powers to curse Andredelle
In the shock that her younger sister got engaged, to a complete stranger, Queen Elsa goes berserk on Arendelle and shows her true colours.
Baffled and in complete shock over what her sister had just done, Elsa and Anna get into a heated argument over whether Anna should be allowed to marry Prince Hans of the Southern Isles. The moment Anna removes the glove off Elsa's hand, a blast of ice shoots out her hand and freezes into an icy shard. The whole room stops breathing as they watch Elsa run out of the room and onto the streets of Arendelle.
As the crowd starts gathering around her wondering what is wrong with their queen, Elsa starts panicking and freezes everything in sight. As the crowd starts screaming in terror, it gets even worse.
Anna runs up to her sister trying to comfort, but is stopped by sharp icicles, nearly stabbing her. Seeing that she was about to kill her own sister, Elsa starts to flee with Anna pursuing her
Elsa starts running towards the mountains, in the attempts to escape her actions. As she runs across the river (yes, she can run on water), the water beneath her feet start freezing over the fjord. Soon the whole body of water is frozen, and in the process the ships that brought their guest here are trapped in the ice. This brings an eternal winter upon Arendelle and the kingdom has no other choice than to stay and survive this winter.
The Duke of Weleston decides that kingdom should take action over Elsa's actions but Anna intervenes and becomes determined to coax her to come back and stop the eternal winter. Anna sets off on her horse to go find her sister and leaves her fiancé, Prince Hans, in charge of the kingdom.
Will Anna succeed on finding Elsa to stop this winter in time? If not we will have to dethrone Elsa and find someone more fit to rule Arendelle.
