EDIT: This is the basis of the "Rider" series, the first book being Rogue. It is updated (will be) at the same time as the second book, Rebel. Please go check those out if you like this idea!!

I don't even know where these ideas are coming from XD

I'm literally sitting doing arts and this came to mind.
(And no it wasn't HTTYD art, I'm not that good)

What if in the first movie, Stoick the Vast did not forgive Hiccup for training a dragon in secret? What if Hiccup and Toothless ended up facing the Red Death alone? Shunned and banished from Berk, Hiccup and Toothless leave the village and search for themselves alone. They found Dragon's Edge not as a place to continue discovering and researching dragons, but as a place for them to find sanctuary. Another rogue rider joins him in his journey, having also been shunned by the people of Berk just for riding her own dragon. Five years later, the original Dragon Rider pair now known as Flame and Nightmare are called to Berk by a mysterious message, and pulled back into the ones who had originally disgraced him for doing what, in the end of another time, was right.

Eventually I'm going to actually put most of these ideas into writing. Right now they're here to see how people react? I'm just kind of jotting what I think are decent ideas into this book, since I have way too much time on my hands to think but nothing to actually update event wise XD
