(NOTE: This fanfic takes place after the second HTTYD movie) What if there had been a mistake? What if Hiccup had the chance to bring his father back to life? But he had to travel to Valhalla itself to do so? After the death of his father, Stoick the Vast, Hiccup Horrendus Haddock III is visited by Odin (the king of Asgard) in his dream, informing Hiccup that Stoick wasn't ready to die yet and Hiccup could revive him if he is willing to travel to Valhalla. Without hesitation, Hiccup accepts the offer and with Toothless' aid, Hiccup begins his journey to Valhalla to rescue his father.
