Harry Potter himself could be a potential candidate. Given his unique connection to Voldemort and his own powerful magic, it's not a stretch to imagine him being the heir of some long - forgotten magic. Another could be Hermione. Her intelligence and thirst for knowledge could be signs that she has a deeper connection to a magical heritage. Ron could also be a candidate, as his family has a long history in the wizarding world and there could be some hidden magic in his bloodline.
Some fanfictions might consider a new character as the Heir of Magic. Maybe a long - lost relative of one of the founders of Hogwarts. For example, a descendant of Rowena Ravenclaw could be the heir, with their inheritance being a deep understanding of ancient magic and wisdom. Or it could be a character from a different magical community that has a connection to the magic of Hogwarts. This would open up new storylines and interactions between different magical cultures within the fanfiction.
In fanfiction, Neville Longbottom could be a strong candidate for the Heir of Magic. He has shown great courage and has a connection to the plants and the magical side of nature, which could be related to an ancient magic. Luna Lovegood is also a possibility. Her unique view of the wizarding world and her ability to see things that others can't might indicate that she is the heir of a special kind of magic. And don't forget Ginny Weasley. Her experience with the diary of Tom Riddle and her own strong will could make her a candidate for this role.
It could be a previously unknown character, like a distant relative of one of the main families in the Harry Potter series. Maybe a long - lost cousin of the Weasleys or a descendant of one of the founders of Hogwarts that has been living in hiding.
It could be a new character introduced specifically for this fanfiction. Maybe a transfer student from a far - off wizarding school with a mysterious Roman heritage.
Another possibility is a student at Hogwarts who has always been in the background. A shy or overlooked character who suddenly discovers that they are the unknown heir. For instance, Neville Longbottom could be an interesting choice. He has shown great courage and growth throughout the series, and if he were revealed as the heir, it would give his character a whole new level of importance.
Perhaps it could be a long - lost relative of Harry Potter himself. Since Harry has so many mysterious aspects to his own story, it wouldn't be too far - fetched for a relative of his to be the heir. Another possibility is a character from one of the minor wizarding families that has been overlooked in the original series but actually has a strong connection to the swords.
One potential character could be a new student who arrives at Hogwarts with a mysterious past. He shows extraordinary magical abilities that seem a bit too dark for the normal wizarding world. Another could be a distant relative of Draco Malfoy. Since the Malfoys have a history with the dark arts, it wouldn't be too far - fetched for one of them to be revealed as the heir of Sauron. Or perhaps an old wizard who has been in hiding for centuries and resurfaces as the heir of Sauron.
Perhaps it's a character from a minor magical family that was thought to be extinct. Their heir could have powers that are a combination of ancient magic that was thought to be lost. They might have the ability to communicate with magical creatures in a way that no human has been able to do before, which would make them very powerful in the eyes of both those who want to protect magical creatures and those who want to use them for their own gain.
It could be Harry Potter himself. Since he has so many special qualities and a deep connection to Hogwarts, he might be revealed as an heir. Maybe he has some latent powers related to one of the founders that haven't been discovered yet.
One interesting plotline could be the discovery of a new kind of magic that the heir of magic possesses. This new magic might be a blend of different existing magics in the Harry Potter universe, allowing for unique spells and abilities.
One interesting plotline could be the discovery of a new, hidden magical ability that the heir of magic possesses. This ability might be something that even Voldemort didn't know about and could turn the tide in battles against dark forces. Another could be the exploration of the heir's family history, uncovering secrets that have been long buried in the wizarding world. For example, they might find out that their family had a connection to an ancient and powerful magical artifact that could change the balance of power in the wizarding community.
A smart and studious character like Hermione could be a possible heir. She has a thirst for knowledge which is very Ravenclaw - like.
