Hiccup Haddock was once a said to be a useless runt of Berk. But everything had changed when he had befriended and trained a Night Fury named Toothless. He soon decided to run away from Berk as well as its people, since he knew that they didn't care about him and had despised him since he was born. He decided to explore the world and make a tribe of his own with all the Dragon Riders he had befriended in his travels. The Night Tribe, the most mysterious and powerful tribe of them all, with close alliances with the Berserker Tribe, the Outcast Tribe, the Defenders of the Wing, and the Wingmaidens. But what happens if the past comes back to haunt him? What will happen? What will he do?
