A small disturbance can cause an avalanche, metaphorically speaking. Small changes in how events play out, caused by little changes in how the world works can have a big impact on unexpected people. (Diehard fans of Astrid, consider yourselves warned. You might not like what is coming.) AU. Starts off like the first movie, veers massively away from the original by chapter 9.

After being gone three years, a Hiccup who has left his mark in the world comes to Berk by chance and ends up saving it from the Outcast. Deed done, he wants to go back to exile, but some Berkians conspire to keep him closer to home...

The punishment for murder is death. When Hiccup commits the unholy sin, he is cast out, exiled for his crime. All hope seems lost for him. But his Fate is not yet over and now he must face new troubles, new feelings and a new future outside the world of Berk. But can he move on from his troublesome past and his dark, dark secret?
