What could be the implications if Hermione Granger was of a noble house in fanfiction?

Yes, there are many such fanfictions. Some authors like to explore different family backgrounds for Hermione. In these fanfictions, she might be part of an old and noble wizarding family, which can bring a whole new set of storylines. For example, it could change her relationships with other characters like Harry and Ron. Her status in the wizarding world would be elevated, and she might have access to different kinds of magic knowledge or artifacts that are exclusive to noble houses.

Well, it could be about Hermione and Crookshanks having some sort of magical adventure together. Maybe they discover a hidden part of Hogwarts that only Crookshanks' cat - like senses could detect. And Hermione uses her vast knowledge to solve the mysteries they encounter there.

Well, it could symbolize a new beginning. Just like in real life, a new haircut can mark a change in a person. In fanfiction, Hermione getting a haircut might show that she's ready to break free from her old self, perhaps be more daring.

The plot could revolve around the older sister being a secret agent of the Order of the Phoenix. She could be involved in dangerous missions while also trying to protect Hermione from getting too involved in the dangerous wizarding politics. For example, she might try to keep Hermione away from Harry Potter's dangerous adventures at first.

Maybe she leaves because of a conflict. It could be with a teacher who doesn't support her unorthodox ways of learning or a fellow student who makes Hogwarts an unpleasant place for her. In fanfiction, there could be a lot of creative interpretations of such conflicts.

She could make a spell - powered communication device. This would be like a magical version of a smartphone. It could allow wizards to communicate instantly across long distances, even in places where normal communication spells don't work. It would be a great invention considering how often wizards need to communicate in the wizarding world.

Well, as a centaur, Hermione would likely gain some centaur - specific magical powers. She could use her enhanced speed and strength to explore areas that were previously difficult for her as a human. And she might communicate with other centaurs in a way that reveals new magical secrets about Hogwarts or the Forbidden Forest.

Well, in a Hermione Granger family reunion fanfiction, perhaps Hermione gets to introduce her wizard friends to her Muggle parents in a really fun way. Maybe they have a big dinner where they share magical stories that Hermione's parents are just amazed by.

It's a really strange concept. In the original 'Harry Potter' universe, Hermione is firmly on the side of good. But in fanfiction, if she's a Death Eater, it could be a result of a time - travel gone wrong. She might have made a different choice in an alternate timeline that led her down the dark path. But again, this is very much against the essence of her character.

Well, one way it could work is by having Hermione's love for knowledge translate into an interest in the Shadowhunter world. Maybe she stumbles upon some Shadowhunter lore in the Hogwarts library. Since she's always eager to learn, she becomes a huge fan. She could start comparing the magic in the Shadowhunter universe with that of the wizarding world, like how their runes are different from spells.
