If Hermione is Orion's daughter in a fanfic, her character might become more complex. She could have a stronger sense of loyalty to her family's legacy, which might conflict with her loyalty to her friends at times. Also, she might develop a more regal or commanding presence, as if she has a birthright to lead or influence.
She might become more conflicted. Knowing that Severus is her father could make her question her identity. She was always seen as a Muggle - born witch, but now with a pure - blood father, her self - perception could change.
It would change the plot a great deal. Hermione's origin being Orion's daughter could mean she has access to different resources or knowledge. Her role in the fight against Voldemort might be more strategic as she could draw on the family's secrets or influence. And her friendships, like with Harry and Ron, could be affected as they might see her in a new light, maybe with more mystery surrounding her.
One possible setting could be a charming French village near the Beauxbatons Academy. They might live in a cozy cottage surrounded by magical gardens filled with French - native magical plants.
Another plotline could be Hermione exploring her dark magic heritage. She might be tempted to learn some of the spells that Bellatrix was known for, but then struggle with the moral implications. This internal conflict could be a major part of the story, as she tries to balance her Gryffindor values with her new - found connection to a dark past.
Hermione might develop a stronger sense of loyalty towards her family's name. As Sirius was from the Black family, she would want to uphold the family honor, which was previously tarnished. So she could be more protective of her family's legacy in the wizarding world.
The possible implications are quite serious. Firstly, it distorts the characters. Hermione should be seen as a free - thinking and strong - willed individual. This kind of fanfiction would change her into a submissive and oppressed figure, which is a huge departure from her true nature. Secondly, it can be offensive to fans who love the original positive and progressive themes of the series. It might also encourage wrong ideas about power and subjugation in relationships among readers, especially younger ones who are fans of 'Harry Potter'.
Hermione's relationship with her friends would be full of challenges. Ron, in particular, might have a hard time getting over the fact that she's related to Voldemort. Harry, on the other hand, might be more understanding due to his own complex family history. They would all have to re - evaluate their friendship. Hermione would have to work hard to show that she's not like her father and that their friendship means more to her than any dark family ties.
For Hermione, she might develop a more empathetic side towards Snape. She could start to understand his past traumas and the reasons behind his cold exterior. This could make her less judgmental and more open - minded. As for Snape, he could soften up. With Hermione's influence, he might show his more vulnerable side and let go of some of his grudges, especially towards the students he disliked at Hogwarts.
One possible plot could be that Hermione fakes her death to go undercover and spy on the Death Eaters. She might have discovered a crucial piece of information that can only be obtained by infiltrating their ranks secretly, so she stages her death to avoid suspicion.
If Hermione was Yaxley's daughter in a fanfic, her Hogwarts experience would be full of challenges. She would be constantly torn between her family's dark reputation and her own desire to do good. She might be sorted into Slytherin instead of Gryffindor. In Slytherin, she would have to navigate the complex politics of the house which is known for producing dark wizards. But at the same time, she could also find some allies within the house who are against the Death Eaters' extreme ways.
