Oneshot- Hiccup left Berk after failing to prove that the dragons could be tamed. Years later, he returns to save his old home from an Outcast attack. (M for violence)
Just a very short story of Hiccup and Berk growing into their own as they take separate paths before reuniting.
Just another Hiccup leaves AU - Hiccup leaves with the arena dragons to go after Toothless and the Berkians, leaving the teens behind. The arena dragons carry Hiccup and Toothless' bodies away before they are found by Stoick, leading the Berkians to believe that their heir is dead. Full story of my oneshot 'Return of a Demon'
