Before Hiccup ever set foot in the Dragon Killing Arena, another group faced the flames first.
On the Isle of Berk, young Vikings are trained to face dragons, but Draven, Hiccup's older cousin, is tasked with something greater: leading a mission beyond the village's shores. When the journey turns disastrous, Draven and his crew of five are swept off course and lost to the endless sea.
Now stranded in the far reaches of the Archipelago, they must battle storms, strange lands, and dragons unlike any they have known, all while holding on to the hope of finding their way back to Berk. Every island brings new dangers, every choice tests their unity, and the further they go, the more they realize the journey home may change them forever.
Hiccup was always considered the weakling of the village, he was bullied, pushed around and beaten up by all the other teens, even his cousin and the girl he loved. but it was only until one day when he shot down a night fury the most feared dragon in the whole archipelago, the so called offspring of lightning and death itself. But when he couldn't kill the dragon he took the other option... and trained it. him and toothless were the best of friends but one day when he is chosen to kill the monstrous night mare in dragon training , he can't handle it so he runs away on the back of toothless, but only for the two to be snatched up by dragons.
but 5 years later when hiccup returns to Berk, he is not the hiccup they all once knew.
