Dumbledore could still be an important character. Even though the focus is on Harry being taken in by the Blacks, Dumbledore's overarching influence on Harry and the wizarding world in general would still be present. He might be monitoring Harry's situation with the Blacks, guiding him from a distance, or even interfering when he thinks things are getting out of hand. His wisdom and power would be a contrast to the more family - oriented and often morally ambiguous world of the Blacks.
Bellatrix Lestrange could also be a main character in some versions of this fanfiction. Despite her being on the 'dark side', her complex relationship with the Black family and her powerful magic could make for some intense storylines. Harry might have to deal with her in some way, either trying to redeem her or facing her as an enemy. And of course, Remus Lupin could be involved too, as he was friends with Sirius and has a connection to Harry. His werewolf nature might add another layer of complexity to the story.
One possible plotline could be Harry learning about the Black family secrets that were long hidden from him. Maybe he discovers some ancient magic that was passed down within the Black family and uses it to his advantage in his fight against Voldemort.
In this kind of fanfiction, Neville Longbottom could also emerge as a key character. He has shown great courage and growth throughout the Harry Potter series. When Hera enters the picture, Neville could be the one who has an unexpected connection with her. Maybe his family's long - forgotten magical heritage has some link to the Greek mythology that Hera represents. And then there are the Death Eaters. If the story is set during the darker times in the wizarding world, the Death Eaters might see Hera as a new threat or a potential ally, making them important characters in the fanfiction as well.
Definitely characters from both 'Charmed' and 'Harry Potter'. From 'Harry Potter', Harry, Hermione, and Ron are very likely to be main characters as they are the central figures in the original series. In 'Charmed', the Halliwell sisters, Prue, Piper, and Phoebe, would be prime candidates. Their different powers and personalities would create interesting dynamics when interacting with the 'Harry Potter' characters.
Obviously, Harry Potter would be one of the main characters. He's the central figure in the original series. And Ophis, as the other part of the fanfiction's title, would also be a main character. Her unique abilities and personality would play a big role. Hermione and Ron could also be important as they are Harry's closest friends and would be involved in any new adventures that come about due to Ophis's presence.
Harry Potter himself could still be a main character. He has faced many enemies and situations where he has to make tough decisions. In a 'no forgiveness' scenario, he might be more hardened and less likely to give second chances. For example, when dealing with Voldemort's followers, he could be more ruthless.
The main characters would surely include Harry Potter. He's the center of the story as he is the one with the Veela aspect. Ginny Weasley could also be a major character. If Harry is a Veela, it would change their relationship dynamics. Additionally, Dumbledore might play a significant role as he would be guiding Harry through this new discovery and helping him understand and control his Veela powers.
Ron Weasley would be there too. He would add a bit of humor to the story. He might be the one who is a bit clumsy at first in the MMO but then has some unexpected moments of great skill, like when he discovers a new way to use a simple in - game tool in a creative way during a battle.
Harry Potter for sure. And then, there could be a young local witch or wizard who becomes Harry's friend and helps him understand the North better. Dumbledore might also play a role, perhaps he sends Harry on this mission to the North in the first place. Additionally, there could be some antagonists, like a group of dark wizards who are causing trouble in the North and are opposed to the changes Harry is trying to bring.
Well, Harry Potter himself is very likely to be one of the main characters. Since it's about a second chance, he could be the one to experience this chance and make different choices. Hermione Granger and Ron Weasley are also likely to be main characters as they are Harry's closest friends and would be involved in any major changes he makes.
There could be new characters introduced as well. For example, a young wizard or witch who has been living in the magic sanctuary all their life and knows all its secrets. They could be the guide for Harry and his friends when they enter the sanctuary. And, of course, some of the magical creatures in the sanctuary, like a centaur or a phoenix, could have personalities and roles that are almost like characters themselves, helping or hindering the human characters in their adventures within the sanctuary.
