Change without consequence

Hermione will use time magic to go back in time, and impregnate the women in her male friend's life. She'll breed their lovers in the past with the very children that exist in the present, before returning to the present. All those of whom trusted her, are oblivious to the deception and traitorous plans of the well-respected friend and honorary sister.

(If you want to write a story strand pls read the first strand to get an understanding of the time travel mechanics. Remember that Hermione is not trying to change the future, because it's unpredictable after the past has been changed, and not in her hands. I've invented a fictional future protection shield that means that as long as Hermione does the rectifications, her future and now her child's future remains as it would've been naturally.

I've also not really given any thought into her motivations, I just had a concept and wrote it. If you wish to write up your own versions of her motives, feel free to do so)
