Hiccup and the other dragon riders have finally discovered all the dragons and stopped their war with the berserkians, and dagur finally turned over a new leaf. However, what the gang have not realized is what mysterious dangers lurk in every Island. New Hunters, New Allies, and even New Dragons (or so it seams). But not only this, a great danger is coming. something that the gang has never faced before. Will they find and fix the situation that is disrupting the nature of the Archipelago and its inhabitants?
