Hiccup is devastated, he has been chosen to kill the dragon. But he can't, that would be betraying Toothless, not that he would be able to do it anyway. What would happen if he ran away, never to return? Well that's exactly what he does. And if misfortune leads the gang to his island 5 years later, what will happen? And what adventures will follow?
