The plot could involve Hermione learning about the Black family's dark secrets. For example, she might uncover ancient spells or curses that the family has been hiding. And as she grows up, she uses her knowledge and intelligence to either break free from the more negative aspects of the Black family legacy or to reform the family's image in the wizarding world.
I'm not sure of a specific title, but in general, such a fanfic might focus on how Hermione's intelligence and strong - willed nature would interact with the strict and often secretive Black family values. She could bring new perspectives to the family, while also being influenced by their pure - blood heritage. Maybe there's a fic where she discovers hidden Black family magic with Arcturus's guidance.
One interesting plot point could be how Harry's upbringing by Arcturus Black changes his perception of the wizarding world. Maybe he's taught different magic than what he would have learned at the Dursleys or Hogwarts. Another could be how his relationships with other characters, like Sirius, are altered. Since Arcturus is an older Black family member, he might have different views on family loyalty compared to Sirius.
One plot idea could be that Hermione discovers a long - lost spell book that once belonged to Arcturus Black. As she delves into it, she starts to have visions of his life and the secrets he held. This could lead to her unearthing a mystery within the wizarding world that was thought to be lost. Another idea is that Arcturus Black's spirit is somehow trapped, and Hermione, with her intelligence and knowledge, is the only one who can free him. In the process, they form an unexpected bond that defies time and the norms of the wizarding society.
One possibility could be that Arcturus Black imparts unique magical skills to Harry Potter. Maybe he teaches Harry some ancient and powerful spells that are not commonly known at Hogwarts. This could give Harry an edge in his battles against Voldemort and his Death Eaters.
One possible plot could be that Harry discovers a long - hidden connection between his family and Arcturus Black. Maybe Arcturus has some secret knowledge about Harry's parents or his destiny. They could team up to fight against a new dark force emerging in the wizarding world, with Arcturus using his old - fashioned but powerful magic and Harry his more modern skills learned at Hogwarts.
Well, one possibility could be that Arcturus Black uses his powerful magic skills to rescue Harry from a dangerous situation. Maybe Harry is trapped in a dark wizard's lair, and Arcturus arrives just in time to fend off the bad guys with his advanced spells.
In such a fanfiction, Harry might grow up with a different set of values and skills. Arcturus Black could instill in him a more traditional pure - blood wizarding family's knowledge. He may have different magical training compared to what he got in the original series, perhaps more focused on family - specific magic or ancient spells.
In the fanfiction, Arcturus Black is likely an important figure in the wizarding world. He might be a powerful and knowledgeable wizard from the Black family. Maybe he has a long - standing reputation for his magical abilities and wisdom, which is why he is chosen to train Harry Potter.
Arcturus Black might be portrayed as a wizard with a deep understanding of ancient magic in the fanfiction. He saves Harry Potter perhaps because he sees in Harry the potential to defeat the dark forces that are plaguing the wizarding world. His character could be a blend of mystery, power, and a sense of moral obligation towards Harry.
One plot twist could be that Hermione discovers she has a hidden connection to the Malfoy family, like she's a long - lost relative. This would add a whole new layer to her being raised by them. Another could be that she uses her knowledge of both the Gryffindor and Malfoy ways to broker peace between the two factions in the wizarding world that are often at odds. Maybe she uncovers a secret plot within the Malfoy family that goes against her new - found loyalty to them, forcing her to choose between her upbringing and what she believes is right.
