"An everyday man gets thrown into the world of twilight thousands of years before the start of the plot. With immortality and incredible abilities. How will this man's presence change the outcome of the original story?" [ this is a slow-burn fanfiction; the MC is just trying to experience life and enjoy it, not to take over the world and rule from the shadows.] I do not own twilight or the characters of the twilight world, all that belongs to me are my own characters.
to be honest, I haven't seen many HTTYD fics, and the ones I have seen are part of some kinda multiverse fic and stay in the world for only a couple chapters,or a fic that was dropped or on hiatus, or the MC is trying to do their own hiccup arc and is some Soy boy in the beginning.
