In this fanfiction, Harry Potter is probably the central figure as it seems related to his new identity as the Heir of Death. However, other characters like Dumbledore could play significant roles. Dumbledore might be guiding Harry through this new discovery, or perhaps he's been hiding some secrets about the Heir of Death all along. Additionally, we may see characters from the dark side, like Voldemort or his followers, being involved in the story, either trying to stop the heir or use their power for evil.
Obviously, Harry Potter would be one of the main characters. Since it's about him being the heir of Windsor, his character would be central to the story.

Obviously, Harry Potter is a main character as the heir of Excalibur. Hermione Granger would also likely be involved. She is always by Harry's side in the original series, helping him with research and providing intelligent solutions.

Hermione and Ron could also be main characters. They are Harry's best friends in the original series and it's likely they would be involved in the story. Hermione with her vast knowledge of magic could help research about the Anubis heritage, while Ron could provide support and his unique brand of humor. Their presence would add familiarity and also a sense of friendship and teamwork to the fanfiction.
In some versions, there could be a love interest for the heir of God. This character could add another layer of complexity to the story, as the heir has to balance their relationship with their quest for knowledge about their identity and the use of their powers.

In this fanfiction, the main characters could be quite diverse. Since it's about a 'dark heir', there would likely be a character who embodies this role.

His friends, like Hermione and Ron, could also be part of the story. Additionally, there could be other magical beings or characters from the 'Harry Potter' lore, such as members of the Order of the Phoenix or Death Eaters, who are drawn into the plot due to the emergence of the dark heir.
The heir themselves would be a main character, of course. And Harry Potter might still play a role, either as a friend or a rival to the heir. Dumbledore could also be a major character, guiding or observing the heir's journey.
Typically, the main character would be the heir of Avalon. They are often a new character inserted into the Harry Potter universe.
