How Do You Fight A Nightmare? (ROTBTFD)

Princess Anna of Arendelle is gone, and Elsa will do anything to save her. She'll go on a journey, storm the land, even sail across the sea to the horizon. But will she be able to get along with those four people who claim to be her only hope?

Jack didn't want this job. It just wasn't for him. As the guardian of fun, he should be out there throwing snowballs, not sitting in a diplomatic meeting in a room full of people who can't see him, and one person he wished that couldn't have seen him. But when the princess got kidnapped, he know that he'll do whatever he can - because no matter how he hate himself for it, he just can't stand the queen's sorrow.

Raponzel had never thought that this trip to meet her long-lost cousins will turn out like this. But here she is, on a trip to save a girl she had barely met before, with an invisible boy, crazy archer, and a dragon. And as she thinks it can't be worse, she runs into the last person she wanted to see. Person she believed who was dead.

Merida is furious. Her brother was kidnapped, by the same woman who cheated her three years ago. The same woman who turned her mother into a bear. Merida had changed her fate- or had she? No matter what she does, everything she do seems to only cause more sadness. Perhaps she can not escape her fate, after all?
And worse of all- was it her fault that her family was ripped apart?

Hiccup feels guilty. He has to go on a quest to save the princess of Arendelle - princess who was kidnapped by the most terrible person he know, who used Hiccup's name to do it. Hiccup has to find him- and finish him one and for all. Because a world that ruled by Draco Blood Vist, is a nightmare world.

Their nightmares are rising. Their fears are growing. Their minds are falling apart. And there's only one person who would gain from it- the king of nightmares, the lord of darkness, the master of shadows.
