There might be an original character created specifically for the fanfiction. This character could be an experienced runemaster who takes Harry (or another character) under their wing. For example, a mysterious wizard from a far - flung magical community who has mastered the art of runes and comes to Hogwarts to share their knowledge.
Hermione could also be a main character in such fanfiction. Given her thirst for knowledge, she would be eager to learn about runes. She might be the one who discovers ancient rune texts in the library and sets off a chain of events that leads to the exploration of runemastery in the story.
It depends on the specific fanfiction. There are countless fanfictions out there, and while some might make Harry a Runemaster, others may not. Some fanfictions might focus on his existing abilities from the original story, while others could take a completely different turn and give him this new role.
The main thing that makes it unique is the combination of Harry Potter and runemaster. In the original series, runes are not as prominently featured as other forms of magic. So, in this fanfiction, it gives a new dimension to Harry's character and the magic in the Potterverse.
It could be. Fanfiction is a vast world where fans get to play with the existing elements of a story and create something new. In the case of 'harry potter is a runemaster fanfiction', it offers a different perspective on Harry's abilities. Since the Harry Potter series has such a large and diverse fan base, there will always be some who are interested in this kind of creative re - imagining. Those who are particularly fascinated by the more esoteric aspects of magic, like runes, would likely be drawn to this type of fanfiction.
One interesting idea could be the exploration of new magical runes and their powers. In the 'Harry Potter' universe, magic is already diverse, but fanfiction might introduce runes that can control elements in unique ways, like a rune for instant water - making during a drought - like situation at Hogwarts.
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.
It could be that Dumbledore plays a more prominent role in this fanfiction. Since it's about 'the truth', perhaps Dumbledore has some secrets that are finally revealed, and he becomes a central figure in guiding Harry towards understanding. Additionally, some minor characters from the original series might be elevated to main characters if they hold key pieces of the truth.
I'm not sure specifically as it depends on the particular fanfiction. But it could include Harry Potter himself, perhaps having a special connection to Ancalagon. There might also be new characters created specifically for this fanfiction that are key to the Ancalagon - related storylines.
It's hard to say for sure without reading it, but it's likely that Harry Potter himself would be one of the main characters. He could be at the center of the story, dealing with the brimstone - related events. Hermione and Ron might also be involved, using their skills and knowledge to help Harry figure out what's going on with the brimstone mystery.
The main characters are usually James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew. They are known as the Marauders. James is often depicted as a confident and talented wizard. Sirius is the rebellious one, with a bit of a wild side. Remus is the more reserved and intellectual one, due to his condition as a werewolf. And Peter is the tag - along, though his character can be quite complex in different fanfictions.
Hermione Granger might also be a main character. Given her intelligence and thirst for knowledge, she would probably be involved in researching about Phobos and its implications in the magical world. She could be the one to figure out how to use or counter any threats related to Phobos.
