How to Train Your Dragon

[You are a guy]

You are a Viking, this is a very, very old world, with dragons, Vikings, etc.

You are the son of your tribe's chieftain and are soon to become the new chieftain...but will you? That's the question, since your tribe has been at odds with the dragons for many years.

It was another night and dragons attacked you, everyone defended themselves, etc., you tried to help but everyone drove them away and drove them away... at the moment of the whole House, you saw a night fury, the rarest and most dangerous species.

And you shot him down! Soon it was all over, but no one believed it. The next morning, you went looking for him in the forest. There were signs that something had fallen—trees were broken and there was a large trail on the ground. You followed it, reaching a cliff where there was a hole with a small lake... and you saw him—a real Night Fury!.. Only he wasn't quite a dragon, but in human form? Yes... dark with large wings and a tail... shields on some parts of his body, and some kind of armor? covering his body.

He was bound in the nets you'd caught him in. When you came down, he was unconscious, about two meters long. You got closer, drew your knife, and was about to kill him...but something kept you from doing so.

(the rest of the action is up to you)
