A little under a year after defeating The Red Death, Hiccup and Toothless are flying around Berk, on a small island they find a book about Hiccups family. The insides reveal a forgotten time where humans and dragons lived in harmony, dating all the way back to over a thousand years ago when Hiccup Horrendous Haddock I, became the first King of the Wilderwest. This fanfiction draws inspiration from the original book series, such as characters, places, and objects, if you want to know more about these things I advice visiting the Wikia, and boing to the book section.
