There could be original characters created specifically for the fanfiction. For instance, a mysterious weapon master from a far - off land who comes to Hogwarts to share his knowledge. This character could be very popular as they bring in new elements and a sense of mystery to the story. And of course, some fanfictions might focus on the darker characters like Draco Malfoy, who could be tempted by the power of these new weapons and have a complex character arc related to them.
Harry Potter himself is obviously still very popular in these fanfictions. People love to explore different aspects of his character. Hermione Granger is also quite popular as she is often given more complex storylines, like her delving deeper into ancient magic. Draco Malfoy is another one. Fanfic writers often like to give him a redemption arc, showing his character growing and changing in ways that were not fully explored in the original books.
Hermione Granger is also a common focus. Her intelligence and knowledge of magic can play an important role in stories where Harry is becoming a master of magic. She could be helping him research or even be involved in his magical training in some unique ways.
Harry Potter himself is obviously a very popular character in these fanfictions. Writers often explore different aspects of his character, like what if he had been sorted into Slytherin. Hermione Granger is also a common focus. Fanfic authors might give her new magical achievements or put her in situations where she has to use her intelligence in even more creative ways. And then there's Draco Malfoy. Many fanfictions explore his character in more depth, perhaps showing a more sympathetic side to him, or his struggle to break free from his family's dark influence.
Hermione might also be a main character. Her intelligence and knowledge of magic would be invaluable in dealing with whatever the weapon in Gringotts is. She could be the one to figure out how to unlock the secrets surrounding the weapon, like deciphering ancient runes or understanding complex magical texts related to it.
Harry Potter himself is often a central and very popular character. He's usually the one on the journey to become a master enchanter. Hermione Granger is also popular as she often aids Harry with her extensive knowledge. And sometimes, Severus Snape can be a key character, perhaps as a mentor or an obstacle in Harry's path to enchanter mastery.
Another concept might be the idea of a weapon master character who has special abilities to train others in the use of these magical weapons. This character could introduce new fighting styles and strategies that are different from the traditional magic used in Hogwarts. They might teach how to combine physical combat with magic through these special weapons.
Obviously, Harry Potter is one of the main characters as it's about his mastery of illusions. His friends like Hermione and Ron are likely to be important as well. They would probably support Harry in his journey to master this new skill and use it for good.
Well, surely the illusion master would be one of the main characters. But there could also be some of the original Harry Potter characters like Harry, Hermione, and Ron. They might interact with the illusion master, either as friends or as people who are initially skeptical of this new form of magic.
Obviously, Harry Potter would be one of the main characters as it's in his name. He's likely to be the one with the power of the master of storms. Hermione Granger and Ron Weasley would probably also be important characters as they are Harry's closest friends and are often involved in his adventures in any Harry Potter - related story.
In addition to the core trio, we might see some other characters like Dumbledore playing important roles. Dumbledore, with his great wisdom, could either guide Harry in his journey of manipulation or try to prevent him from going too far. Voldemort would also be a significant character. Harry could be using his manipulation skills against Voldemort and his Death Eaters. There could also be new characters introduced, such as a mysterious wizard who teaches Harry the art of manipulation in the first place.
