"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.
This is honestly my favorite HP fanfiction I've read, the amount of world building is insane with all aspects of magic being expanded upon in a reasonable in universe appropriate manner. One prime example is the fact that the Masters of magic actually feel like masters in their subjects not just slightly expanded upon characters that can be equivalent to a housewife.
