A run away fic. Eventual Hiccstrid. Hiccup has found and tamed the most feared dragon of all. A Nightfury. He has been learning secrets about dragons, and these secrets have lead him to be chosen to kill a Monstrous-Nightmare. No one knows about the Nightfury he has named Toothless, but if they did it could only lead to bad things. Hiccup has two choices. Stay, and kill the dragon, or die doing it, all the while losing Toothless's trust, or leave Berk forever, at the same time leaving everything he knows. What will Hiccup choose? And when he chooses, what will happen? My first fanfic, so I hope you enjoy it, and I will try my best to make it interesting! :) Disclaimer: Sadly, no. I don't own HTTYD.
