The main characters can vary widely. Sometimes it's a new student at Hogwarts who has a special connection to the founders' staff. This student might be an outcast or have some hidden power. There could also be descendants of the founders who play a major role. They might have been living in the shadows, but the discovery of the staff brings them into the spotlight and they have to deal with the responsibilities and challenges that come with it.
You'll usually find characters like Godric Gryffindor, Salazar Slytherin, Rowena Ravenclaw, and Helga Hufflepuff. They might be present in spirit or through memories stored in the staff. And then there are the modern - day students who stumble upon the secrets of the staff. They could be original characters created by the fanfiction writer or minor characters from the original books who are given more depth in these stories.
Well, Harry is the central figure through which the story unfolds. The four founders play crucial roles as they are the ones who created Hogwarts. In addition, we might also see some of Harry's friends in the original series like Hermione and Ron, but they might be in a secondary role compared to Harry's interactions with the founders.
Often, the main characters would be the heirs themselves. There could be a character who is the heir of Gryffindor, perhaps a young student who has always shown great courage and a sense of justice. Another main character might be the heir of Slytherin, who at first seems a bit of an outcast because of the negative reputation of Slytherin but turns out to have a complex and important role.
Obviously, the four founders - Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin are main characters as they are being reborn. They bring their unique personalities and magical abilities back to the story.
The apprentice is obviously one of the main characters. They are likely to be a young wizard or witch with great potential. Then there might be characters representing the different houses of Hogwarts, like a descendant of Gryffindor who is a mentor to the apprentice. There could also be a rival apprentice who has different ideas about the founders' magic.
Well, a possible plotline might involve time - travel using the founders' staff. Maybe a character goes back in time to meet the founders themselves and learn about the true purpose of the staff. It could also be that the staff has a connection to a prophecy, and the story follows the characters as they try to figure out what the prophecy means and how it relates to the staff.
It's possible that some of the more minor characters from the original series become main characters in this fanfiction. For instance, Neville Longbottom could play a crucial role. Maybe he discovers something about the Staff of Magnus that others have overlooked, and his new - found confidence leads him to be a central figure in the story.
The main characters would surely include Harry Potter. Since it's about him meeting the founders, he's central to the story. As for the founders, they are key too. Godric Gryffindor might be the most enthusiastic about meeting Harry, seeing in him the true spirit of Gryffindor. Helga Hufflepuff could be the nurturing one, teaching Harry about the importance of hard work and loyalty. Rowena Ravenclaw might offer him wisdom, and Salazar Slytherin could present a more complex relationship, as his views on blood purity might clash with Harry's, but still be an important part of the story as Harry tries to understand and reconcile different magical ideologies.
In some fanfictions, other important characters from the original series like Hermione Granger or Ron Weasley could also be involved. They might help the founders understand the modern world or play a role in the events that unfold during the time - traveling escapades. For example, Hermione's vast knowledge of magic could be useful in deciphering ancient spells that the founders use.
Well, Harry Potter is almost always a main character. He is the hero of the original story, and fans like to see his story continue. Hermione and Ron are also main characters as they are Harry's closest friends. However, in some fanfictions, Draco Malfoy can also become a main character. He might have redeemed himself after the events of the original series and is now working with Harry and his friends to face new challenges in the wizarding world.
Professor Dumbledore is often a popular character in such fanfiction. His wisdom and powerful magic make him a great addition to any story. He can be a mentor figure to Harry in different and unexpected ways, like guiding him through some ancient and dangerous magic that only Dumbledore has knowledge of.
