Well, a possible storyline is Hermione getting involved in a pureblood family's internal power struggle. Maybe she discovers a long - hidden secret within a pureblood family and has to decide whether to expose it or keep it for the sake of the family's reputation. Also, she could befriend some outcast purebloods who share her views on equality and together they try to reform the pureblood culture from within.
One interesting storyline could be Hermione trying to navigate the complex social hierarchies within the pureblood culture. For example, she might have to deal with ancient family traditions and etiquettes that are completely new to her. Another could be her using her intelligence to challenge some of the archaic beliefs held in the pureblood culture, like ideas about blood purity and family status.
Another character could be Blaise Zabini. He is also from a pureblood family. Fanfictions might pair him with Hermione as they explore the pureblood culture together. He could introduce Hermione to different aspects of pureblood society, and they might develop a friendship or something more as they interact.
Well, one possible plot point could be how Hermione's rich pureblood status affects her relationships in the wizarding world. Maybe she uses her wealth to fund some secret magical research.
The idea allows for a new exploration of Hermione's family history. In the original series, her muggle - born status is a big part of her identity. But in this fanfiction, as a pureblood, we could see a whole different family tree, with ancient wizarding lineages, secret family magic, and different cultural traditions that she would inherit and navigate.
A possible plot is that the Pureblood Society has a prophecy about Hermione and Harry that they are destined to either destroy or save the society. As they interact with the members of the society, they start to question their own beliefs about blood purity and the role they are supposed to play according to this prophecy.
If Hermione was a pureblood, it might change how she's perceived by others and her own sense of identity. Maybe she'd have more privileges and face different challenges and expectations.
One idea could be Hermione discovers she has a long - lost pureblood heritage that has some ties to the Death Eaters. Maybe her family was involved in some secret Death Eater plot in the past, and she has to uncover the truth to clear her family name.
Perhaps a storyline where Hermione is a mother in a post - war wizarding world. She has to raise her children in a society that is still rebuilding, teaching them values of peace and unity. This could involve her sharing her own experiences from the war to instill important life lessons.
One interesting storyline could be Hermione finding herself in Gotham City and having to use her magical skills to outwit the Joker. Maybe she tries to stop his evil plans without revealing her magic to the non - magical inhabitants of Gotham. Another could be the Joker getting his hands on some magical item from Hermione's world and she has to retrieve it. For example, if he got a powerful wand, Hermione would need to use her intelligence and magic to get it back before he causes chaos with it.
One interesting storyline could be where Deadpool somehow gets transported to the wizarding world. He'd be his usual chaotic self, confusing the hell out of everyone, especially Hermione. She might initially be put off by his insanity but gradually see his good side as he helps in some sort of magical - mutant mash - up adventure, like fighting a new dark wizard - mutant hybrid villain.
Another custom could be the formal balls and social events. Purebloods often hold grand balls where there are specific rules of etiquette. Hermione in fanfiction might discover that there are proper ways to greet, dance, and engage in conversation at these events. For instance, the order of introduction based on family status and magical power.
