"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.
It's good. Very good. Being trained by Athena, saving Thalia, it's great. I would prefer Percy/Athena but it seems Annabeth is favoured. Keep it up. Try not to make Athena too cheerful.
