Rider

(Complete)

When Hiccup and the others are on a mission to free dragons from dragon hunters, they encounter something they never thought they would. A rider and its white Night Fury.
They try to find out who they are and who the mysterious rider companion is.
Will the riders come willingly to Hiccup? Will the riders be friendly? Is it really Heather on the Razorwhip? Are there more Night Furies? And will it all work out in the end?

*I do not own any of the characters in how to train your dragon except my oc. This story takes place in httyd 3-ish. In my personal opinion, the story could have been better so I am writing this as how I would somewhat want the story to go.*
