"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.
good so far but timeline-wise if you want to add the Magnus chase books then it takes place after the Percy Jackson books because in book one Magnus chase is 16 like his sister Annabeth chase (confirmed in the second book to be the actual one) and in the second book which is only a few months later she was talking about how a god descended and now they have to deal with some roman emperors which is obviously the trials of apollo books which takes place a while after the great prophecy so yeah don't add Magnus chase just yet and there cousins
