Perhaps a major plot point is Hermione's struggle with the expectations that come with being a rich pureblood. She might have to deal with the snobbishness of other pureblood families while still staying true to her own values. Her wealth could also attract unwanted attention from dark wizards or those seeking power, and she has to navigate through these dangerous situations while still being a student at Hogwarts.
In such a fanfiction, a likely plot point would be the reactions of her friends like Harry and Ron. They might be initially shocked by her pureblood and rich background, which could lead to some interesting dynamics in their friendship. Hermione could also use her status to influence the pureblood -centric politics in the wizarding world, perhaps trying to make it more inclusive.
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.
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.
Other pureblood characters like Draco Malfoy would surely interact with her. Given her new status, Draco might be conflicted. On one hand, she's a 'mudblood' in his old view, but now as a rich pureblood, he might have to reevaluate his attitude towards her. And there could be other pureblood families' members who would either befriend or oppose her based on their family politics.
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.
Perhaps in this fanfiction, Hermione gets involved in a situation where she has to use her intelligence to outwit the Lestrange family's enemies. Since the Lestranges are often associated with the dark side, she might find herself in some dangerous and challenging scenarios that test her skills.
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.
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.
In some 'hermione adopts scorpius fanfiction', a great plot point is the relationship development between Hermione and Scorpius. Hermione, being the intelligent and kind witch she is, helps Scorpius with his schoolwork and insecurities. Scorpius, on the other hand, might bring out a more nurturing side of Hermione that we didn't see much in the original series as she was always so focused on her own studies and fighting against Voldemort. This dynamic shift can be really engaging to read about.
One possible plot twist could be that Hermione's pureblood status was hidden to protect her from a dark wizard or an old family feud. When the truth comes out, she has to face unexpected enemies.
Perhaps Hermione discovers she has some sort of connection to Dracken magic that no one else has. This could lead to her having unique powers or abilities that she has to hide from her friends at Hogwarts.
