There could also be new characters introduced specifically for the fanfiction. Maybe a young wizard or witch who has a special connection to the seals from birth. This character could be an outcast in the normal wizarding world but find their place when they interact with the seals. They could then team up with Harry and his friends to explore the mysteries of the seals.
In some versions of the fanfiction, the seals themselves could be considered main characters in a way. They could have their own personalities, desires, and goals. Their actions and interactions with the human characters would drive the plot forward. For example, a particularly mischievous seal might lead Harry and his friends into a dangerous but exciting situation.
Well, Harry Potter would likely still be one of the main characters. He might be the one to discover the seals and their significance in the magical world. Hermione would also be important as she would use her vast knowledge to research about the seals. Ron could be there for moral support and also to join in on the adventures related to the seals.
It's possible that Hermione could be a main character too. She might interact with the Navy Seal character, perhaps learning from their combat and strategic thinking. Another likely main character could be a Navy Seal team leader who gets involved in the wizarding world's battles and forms an alliance with the Hogwarts students.
There might be some original characters created for the fanfic. For example, a wizard who has prior experience as a Navy Seal in the Muggle world and now brings those skills back to the wizarding world. He could be a mentor - like figure, teaching other wizards about things like discipline and combat strategies. Or maybe Ron could also take on a more prominent role, with his loyalty and courage being emphasized in a Navy Seal - inspired context.
The main characters could be put in great danger. For Harry, he might find himself facing new dark forces that were sealed away. Hermione would be scrambling to research ways to fix the broken seal or at least understand what has been unleashed. Ron could be caught in the middle of battles against the new threats that have emerged from the broken seal.
Perhaps it could be a well - known character from the original Harry Potter series who discovers a new aspect of their magic. For example, Hermione might find that she has an aptitude for seal magic while researching some ancient texts in the library. She could then use her knowledge and newfound ability to solve some of the problems in the wizarding world.
One interesting concept could be the unique bond between the characters and the seals. Maybe the seals have magical powers that interact with the wizarding world in unexpected ways. For example, they could be used as messengers in a way that owls can't, like being able to travel underwater to deliver messages to hidden underwater magical communities.
Hermione could be a main character. As a very intelligent witch, she might assist Harry in his teaching, like helping him prepare complex lessons or providing additional knowledge to the students. For example, when Harry is teaching about ancient spells, Hermione could offer insights from the books she has read.
Hermione could be one. She could come to Degrassi to help Harry. She'd be really good at handling the academic side of things there, like helping students with their studies. And also, she could use her magic knowledge to figure out any magical mysteries.
Hermione Granger would likely be a main character. She could use her vast knowledge to help Harry in his efforts to fix Hogwarts, whether it's researching ancient spells for repairs or coming up with new educational strategies.
Hermione could be there. She would be eager to study the different magics and books in Tamriel. Her intelligence would help Harry navigate the new world.
In addition to the ones mentioned, Dumbledore could be a main character in some fanfictions. He knew Flamel, so he could play an important role in stories about Flamel. Voldemort could also be a main character as he was after the Philosopher's Stone, and his actions could be intertwined with Flamel's story. There could also be original characters created by the fanfiction authors who interact with Flamel and the other known characters.
