Another possibility is that the main character is a mysterious outsider who comes to Hogwarts. This person has been trained in the art of seal magic in a far - off land. Their arrival at Hogwarts stirs up a lot of curiosity and also some suspicion as they seem to have powers that are not well - understood in the British wizarding community. As the story progresses, they use their seal master skills to help the students and faculty deal with various threats.
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.
Maybe it's an older wizard who has been studying arithmancy in secret for years. He decides to come out of the shadows and share his knowledge at Hogwarts, becoming the central figure in the story as he mentors the students and uses his skills to solve various magical problems.
A Muggle - born student could be the main character. They might not have the same preconceived notions about magical beasts as the pure - bloods and half - bloods. Their fresh perspective could lead to new ways of handling and understanding the beasts. They could be the one to discover a new breed of beast that has been hiding in plain sight, right on the outskirts of Hogwarts.
Perhaps it could be an older version of one of the main characters from the original series. For instance, an adult Harry Potter who has become a master of certain types of magic and is now on a new adventure. He could be traveling to different parts of the wizarding world to teach or to learn more advanced magic techniques. Another possibility is that it could be a character like Dumbledore in his younger days when he was on his own journey to become the great wizard he was known to be.
It could be a new student at Hogwarts who discovers their talent for runes early on. Maybe they come from a family with a long - forgotten tradition of rune - making and they are the first in generations to revive it.
Hermione could also be a great main character. Given her thirst for knowledge, she might be the one to first study and understand the concept of Haki in the fanfiction. She could then use it to her advantage in battles and also to help her friends, perhaps even using Haki - enhanced magic to break through difficult spells or magical barriers.
It could be an original character created specifically for the fanfiction. Maybe a young wizard or witch who discovers their Shadow Master abilities by accident.
It could be an original character created specifically for this fanfiction. Maybe a young wizard or witch who has always been an outcast in the wizarding world and discovers their unique ability to connect with dark dragons.
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 hard to say for sure without reading it, but it could be the puppet master himself. Since the title mentions the puppet master prominently, it's likely that this character plays a central role in the story.
A lesser - known character like Ernie Macmillan from Hufflepuff could be the main character. As a prefect, he could bring out the unique qualities of Hufflepuff house. He might have to deal with issues like other houses underestimating Hufflepuff students. His story could focus on how he promotes the values of hard work, loyalty, and fairness within the house and the school as a whole.
