There's no way to tell without reading the fanfic. However, it might feature some of the more popular secondary characters from the Harry Potter books like Luna Lovegood or Draco Malfoy. They could be given a more central role in this fanfic, with the story revolving around their own means and ends.
Since it's a fanfic, the author could choose to focus on entirely new characters within the Harry Potter universe. Or it could be an alternate version of the main characters where their personalities or actions are different. It could also be a story that focuses on the teachers at Hogwarts as the main characters, exploring how they use their teaching and influence as the means to an end, such as shaping the future of the wizarding world through their students.
The main characters could include some of the new generation as well. For example, Albus Potter or Scorpius Malfoy. They could be at the center of this 'war' in the fanfic, perhaps dealing with the consequences of their parents' actions. Ginny Weasley could also be a main character, as she's a strong witch in her own right. And then there are the Hogwarts professors. Professor McGonagall could be leading the defense of Hogwarts in this war - like situation, and Professor Flitwick could be using his magical expertise to help the side he's on.
I'm not sure specifically as there could be many different interpretations. It might be a fanfic that focuses on characters in Harry Potter using certain means to achieve their ends, like a character using magic in an unexpected way to reach a goal.
I don't know for sure as I haven't read this particular fanfic. But it could have the main character be an original creation with the 'lionheart' trait, or it might center around a well - known Harry Potter character like Harry himself with some new 'lionheart' - inspired story arc.
Well, in many Harry Potter fanfics, even those named 'the change', the main characters often include Harry, Hermione, and Ron. However, depending on what the 'change' is about, new characters could be introduced or existing minor characters could be promoted to main character status. For example, if the change is about the Slytherin house becoming more inclusive, we might see Draco Malfoy taking on a more central role in the story, along with the usual trio.
It could be a Muggle - born protega. This character would face unique challenges as they try to protect the wizarding world while also dealing with their own identity issues. They might have friends among the Hogwarts students, and together they form a group to counter a new evil force that targets both Muggles and wizards.
Without reading it, it's hard to say. But it could feature the main characters from the original series like Harry, Hermione, and Ron as they are usually central in most Harry Potter fanfics. They might be the ones trying to solve the conundrum.
Since it's a fanfic, the main characters could be a mix of new and existing characters from the Harry Potter world. Maybe it has Harry, Ron, and Hermione in some sort of mentoring role to the new hunters. Or it could be entirely new characters who are on a journey of their own, exploring parts of the wizarding world that haven't been fully explored in the original series, like some hidden areas where they need to hunt for something important.
Most likely, the main character is the healer. They could be an original character created for the fanfic. There might also be appearances from well - known Harry Potter characters like Harry himself, Hermione, and Ron. Maybe the healer has to work with them to solve some sort of magical health crisis in Hogwarts or the wizarding world at large.
In addition to Harry, there could be a unique snake character that is a main character. This snake could have its own personality and motives. It might be a magical snake that has been around for a long time and has knowledge of hidden secrets in the wizarding world. Dumbledore could also be a main character as he often guides Harry in the original series and would likely do so in this fanfic as well, especially with Harry's new snake - related situation.
Well, Harry Potter himself is likely to be one of the main characters. He might be involved in the rebuilding of the wizarding world or dealing with the after - effects of the war. Hermione Granger would probably also be a main character, using her intelligence to help solve new problems that arise.
