A Godfather's Promise

***A Godfather's Promise*** is a non-crossover fanfic by The Metal Sage available at Fanfiction.net. It was first published in 2018; as of January 2021, it has 22 chapters and has reached about 250 000 words. It is rated **Mature** and contains heavy BDSM elements, primarily D/S with Harry as the dominant partner and Fleur Delacour as the submissive, but B/D is also present. The story starts with the Triwizard Tournament, but may end up covering the rest of the war.

Several AU elements are present: the Potter family is said to be the oldest in Britain, going back to an old Roman patrician family *gens Poteria*, and has always been involved in muggle military affairs. Charlus Potter is said to be Harry's grandfather and Dorea Black to have been disowned for her marriage to him (the author does aknowledge that both these facts are non-canonical), and when Sirius was disowned they took him in and raised him as their own. Finally, as the title hints, James made Sirius swear to take care of Harry, and in return Sirius made him tell Dumbledore about the change of Secret Keeper – thus, it was Peter Pettigrew who ended up in Azkaban, and Harry has been raised by Sirius rather than the Dursleys. The result is a Harry who is better built (no malnutrition), well trained, confident and focused on making himself the best he can, in order to live up to his family's illustrious heritage. He has enormous magical potential, and killed Quirrell with a burst of accidental magic that blew up his chest. After that, Harry prioritized his studies and soon passed even Hermione; an unfortunate side effect was that both she and Ron started to drift apart from him, and by the time the story starts he doesn't have any close friends at all.

## Plot summary

Initially, there are only small changes from the canon plot. The view point shifts mostly between Harry and Fleur and we see their respective reactions to each other, Fleur slowly learning to trust a man despite a history of abuse and Harry finding a target for his budding sexuality. Harry also befriends Neville Longbottom, as well as some of his year-mates in other houses – chief among them are Susan Bones and Daphne Greengrass. While the rules of the tournament prevent the school staff from giving Harry any help beyond the ordinarily scheduled classes, Sirius and Remus Lupin take up lodgings in Hogsmeade so that they can train him in the evenings. To help hide it, Dumbledore announces that both Harry and Cedric, as Hogwarts Champions, are allowed to move out of the dormitories and into private rooms.

Sirius, being an inveterate bachelor, has introduced Harry to porn by the simple expedient of not bothering to hide his collection (or even put it away when not in use). With the arrival of puberty, Harry has recently started to actually take an interest, and specifically he brought with him to Hogwarts a few bondage-themed magazines. Eventually, he starts reading the articles as well, and grows fascinated by the concept of a BDSM contract; as a joke, he starts writing one of his own, but unfortunately it is found by Fleur. She is quite upset, since she had hoped his interest was of a different kind, but at the same time she is secretly aroused – and disgusted at herself for being so. Harry, meanwhile, is ashamed of his desires and gives up hope of ever dating her.

However, a week later she is ambushed by a group of sixth- and sevent-year Slytherins intent on raping her; she manages to knock out about half of them but is eventually subdued. Then, by chance, Harry comes across the scene, sees red and attacks. He takes them by surprise, she partially transforms into her battle form, and together they take out the last assailants; when it is over she collapses in his arms and he decides that the best place for her to recover while he goes searching for Madame Maxime is his new private Champion's room. Only, Fleur doesn't want him to leave, so he sends his patronus (an Iceni Black) to the headmistress, Madam Pomfrey and McGonagal. Before they arrive, the two have a few minutes to clear the air between themselves, and when eventually everyone leaves, Harry finds Fleur left his contract behind – signed!

As Harry and Fleur start finding their way with a collar and leash, Luna comes across them and asks some embarrassing questions. Put on the spot, Harry blurts out that it is a medical treatment for "Bitch-flue", thinking it outlandish enough to fit her general worldview. However, she later corners him and asks to be collared as well, not seeing any problem with being one of several girlfriends.

After the First Task, Hermione is reconciled with Harry, but he and Fleur make their relationship official and so Ron never even tries. At the Yule ball, where Harry and Fleur go as a couple, Susan and Daphne in a moment of mutual weakness confess their feelings for Harry to one another, and end up kissing. A late night about a month later, Fleur finds a shivering Luna locked out of the Ravenclaw dorms, and brings her to Harry's room to thaw out. Luna again explains her feelings for the pair, and reveals that Harry will be expected to take two wives anyway, so he can propagate both the Potter and Black family lines. They decide to give her a chance to prove that she would enjoy their BDSM games.
