When Hiccup, Merida, and Rapunzel all die and become spirits, they meet the Guardians. The three plus Jack Frost become the Big Four. They're the only ones who can defeat a rising enemy, but when more problems are caused, things get complicated, and dangerous.

This is a excerpt of a fanfic I'm thinking about writing. If it gets good feedback, there'll be a whole story. It's a school setting where the four attend, the pairings will be Mericcup and Jackunzel. OFFICIAL STORY CHAPTER UP!

SCI-FI AU The crew of the Night Fury - Hiccup Haddock (captain), Merida Haddock (first mate), and Jack Frost (Pilot) - have a habit of getting into trouble. Accidentally rescuing Princess Rapunzel of the planet Corona puts them in more trouble than they can deal with... unless Jack can admit he was wrong. The requested expansion of my submission for day 3 of Jackunzel Week.

But the return of Pitch and the evil Pandora throws the world into chaos once more, so North reveals a legend of the Final Four. It is their destiny to seal Pandora's Box once and for all, but who are these four, and where are the keys they need?
