This is my new HTTYD story but with finally happy ending. Sets in moden RTTE. I mean 18 years old characters from HTTYD in the present day AU. I played Far Cry 3 and I get idea for crossover. Basically it's FC in Scandinavia with HTTYD characters and another plot.

List of HTTYD characters in roles of FC3 characters in crossover:

Hiccup = Jason Brody

Astrid = Daisy

Viggo= Vaas Montenegro

Ryker Grimborn= Hoyt Volker

Atali= Citra

Dagur= Sam Becker

Agent Buck Willis= as himself

Factions: Wingmaidens= Rakyats

Dragon Hunters= Privateers

House Grimborn faction= Vaas's pirates

This is just author note, so next chapter is chapter 1. I have two books about Magnus Chase by Rick Riordan. I use dictionary from the book for more historical accurate about Viking's mythology.
