The Past

Hiccup, two weeks after the events of httyd 3, wonders the Forrest of new berk where he stumbles upon a cave with odd runes inside. Taking a risk he places his hand upon them and closes his eyes.

Upon opening them he is once again standing infront of the nightmare, the day he shot down toothless, not only that the runes gave him knowledge such as how to speak the language of the dragons, how to give people there memory's of the future and now paired with his own knowledge of the future, can he change the past so dragons and Viking's can live to be free again.

(Hiccstrid never happened, so no wedding and all that)
