"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.
I'm angry at myself for not finding this gem of a fanfiction. It checks all the boxes - it has adventure, action, comedy, romance(mc is a bit dense at the beginning but when he figures it out it's worth it) and mystery. All in all a good fire emblem Isekai fanfiction with legend of Zelda elements.
