The implications are vast. Hermione's relationship with Harry and Ron could be strained as they have a long - standing feud with the Malfoys. She might also have access to resources and knowledge within the Malfoy family that could help in her studies or in fighting against the dark forces. However, she would also have to deal with the Malfoy family's less - than - savory reputation and values.
This could be a really interesting concept in fanfiction. Fanfic writers often like to play with established relationships and create new ones. If Hermione is Lucius Malfoy's niece, it could bring a whole new layer of conflict and drama. For example, how would Hermione deal with the Malfoy's pure - blood ideology? And how would the other characters react to this unexpected family connection? It could lead to some great character - development stories and new adventures within the wizarding world.
Well, if Hermione were Lucius' niece in fanfiction, it would create a huge shift in relationships. For one, Hermione's connection to the Malfoy family would put her in a very different social position within the wizarding world. The Gryffindors might view her with more suspicion as she has ties to a well - known Slytherin family. Harry and Ron might initially be distrustful, but as they know Hermione well, they would likely try to understand. Draco, on the other hand, would have a complex reaction. He might be less antagonistic towards her as family ties could force him to be more civil, but at the same time, he would be confused about how to deal with a Gryffindor relative. And Snape would probably be extremely intrigued as Hermione is now related to one of his former students.
Hermione's new family life would be very different. She would be part of the Malfoy family, which is known for their pure - blood pride. Lucius would likely have mixed feelings about having a Muggle - born niece. He might try to 'civilize' her according to his pure - blood values. Narcissa would probably be more accepting, especially if she saw Hermione's intelligence as an asset to the family. Hermione would have to get used to the luxurious but somewhat cold Malfoy Manor. There would be a lot of formalities and expectations that she would have to learn to deal with.
For Lucius, his development could be a slow process. At first, he resents being around Hermione, but as he witnesses her magic and her kind heart, he starts to question his own values. He may begin to see the error of his ways regarding blood purity. Hermione might develop more patience. Dealing with Lucius, who has such different views, makes her learn to tolerate and try to change someone rather than just oppose them.
Hermione could also use her magic skills to her advantage. She is a powerful witch, and in the Malfoy household, she may use her magic to create a space for herself where she can be true to herself. She might also use magic to subtly influence Lucius and make him more accepting of her and her beliefs.
One interesting plotline could be the clash of their different ideologies. Hermione, with her strong beliefs in equality and justice, and Lucius, from a traditional pure - blood family with elitist views. Their marriage, forced by the law, might lead to a power struggle within the Malfoy household as Hermione tries to assert her values.
Lucius has a sense of entitlement that comes from his pure - blood upbringing and family wealth. Hermione, being a Muggle - born (in the original story), has had to fight for her place in the wizarding world. So in fanfiction as siblings, Lucius might initially look down on Hermione's more inclusive views, while Hermione would be appalled by Lucius's prejudice. However, as the story progresses, they could learn from each other. Lucius could become more open - minded and Hermione could understand the pressures of a pure - blood family.
In fanfiction, the relationship between Hermione and Lucius can be quite complex. Some fanfictions might explore a scenario where they are enemies forced to work together due to certain circumstances in the wizarding world. For example, they could be paired in a mission to save Hogwarts from a new dark threat. Their different backgrounds, Hermione being a Muggle - born Gryffindor and Lucius a pure - blood Slytherin, would create a lot of tension and interesting character dynamics.
Another idea is that Hermione is there by accident. She could have been exploring the Malfoy Manor (where Lucius's office is located) out of curiosity or in search of something related to Harry Potter's past. Once in the office, she discovers a hidden secret about the Malfoy family that could change the course of the wizarding war.
