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.
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.
For Hermione, her character can be developed by showing her struggle to adapt to the different time period if it's a time - travel scenario. Her intelligence could be put to the test as she tries to understand the more archaic magic and social norms of Arcturus's time. For Arcturus, his character could start as a rather traditional pure - blood wizard, but as he interacts with Hermione, he could start to question his long - held beliefs. Maybe he begins to see the value in Muggle - born magic and the importance of a more inclusive wizarding society.
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 interesting arcturus black fanfiction could be about his adventures during his school days at Hogwarts. It might explore his relationships with other characters like his family members or friends in a unique way.
One great regulus arcturus black fanfiction is 'The Lost Heir of Black'. It delves into Regulus's hidden life and his relationship with his family secrets. Another is 'Regulus's Redemption' which shows his journey towards making amends for his past deeds. There's also 'In the Shadow of Arcturus' that explores his character in a unique magical setting.
In some Harry Potter fanfiction, Arcturus Black might help by using his family's influence. For example, the Black family has a long history and certain political power within the wizarding world. He could use this to protect Harry Potter from some of the more dangerous pure - blood supremacist groups. He may also offer Harry guidance on the complex politics and social hierarchies of the wizarding world, drawing on his own experiences as a member of an old and influential family.
