Arcturus Black as Harry Potter's heir in fanfic: How is it possible?

It might also mean that Harry inherits certain magical abilities or knowledge. Since Arcturus Black may have had his own set of skills and secrets, Harry as his heir could gain access to them. This could change the way Harry approaches challenges in the wizarding world, like fighting against Voldemort. He might have new spells or strategies at his disposal. Also, it could affect his relationships with other characters. Some might view him differently, either with more respect or with envy. And it could open up new plotlines in the fanfic, such as Harry having to deal with the expectations and responsibilities that come with being Arcturus Black's heir.

The Death Eaters who still hold onto the old pure - blood supremacist views could be main antagonists. They might see the Heir of Arcturus Black as a threat to their ideology, especially if the Heir is trying to change the Black family's ways.

One idea could be exploring how the Heir of Arcturus Black discovers hidden Black family magic. Maybe they find a secret chamber in the Black family home filled with ancient spells and artifacts. Another could be their interaction with Harry Potter. They might team up to fight against the resurgence of dark wizards in Hogwarts.

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.

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.

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.

It could be a previously unknown student at Hogwarts. Maybe a shy Ravenclaw who has always been good at spells that require great intelligence and wisdom, which are traits often associated with Merlin.

He would likely be more reserved. Growing up with Arcturus Black, he'd be influenced by the Black family's rather aloof and traditional ways.

In fanfiction, Arcturus Black may help Harry through magical artifacts. The Black family is likely to have a collection of powerful and rare magical artifacts. He could give Harry access to these artifacts, like a magical amulet that offers protection or a wand with special properties. This would give Harry an edge in his battles and his overall growth as a wizard.

He might be a character who was involved in the politics of the wizarding world. Fanfiction could explore how his influence, either positive or negative, affected the balance of power. And this could in turn impact the events that Harry has to face. For example, if Arcturus Black had made certain alliances, it could change the dynamics of the war against Voldemort.
