Dumbledore would probably still be a significant character. He might be one of the first to suspect Harry's changeling status and guide him in the right direction. And Voldemort could also be involved, either fearing Harry's newfound potential or trying to use it for his own evil purposes.
Well, Harry Potter himself would be a main character, of course. His friends like Ron and Hermione would also likely play important roles as they try to understand and support Harry in his discovery of being a changeling.
Well, it's hard to say for sure without actually reading it, but I'd expect Harry Potter to be one of the main characters, since it's in the title. And perhaps there could be a new character who is the changeling, someone who has to deal with their dual identity of being part of the wizarding world and having this connection to the Dreaming.
In many 'the changeling fanfic' stories, the main characters are likely to be changelings. They might be portrayed in different ways, like a young and naive changeling trying to find its place in the world, or an older, more experienced changeling who is trying to change the ways of their kind. Other possible main characters could be those who are affected by the changelings' actions, like a human village leader who has to deal with the presence of changelings near their village.
The changeling queen is surely a central figure. She might have unique abilities as a changeling that are explored in the fanfic. There could be other characters such as a wizard or a warrior who cross paths with the queen due to the allure of the ambrosia. Their interactions with the queen would shape the story and their own character arcs.
One main character could be a half - blood who has some knowledge about changelings. They act as a sort of mentor to the changeling main character. There might also be a house - elf who befriends the changeling. The house - elf could offer a different perspective on the wizarding world and help the changeling in times of trouble. Additionally, a magical creature like a centaur might play a role, as they are known for their wisdom and might be able to give the changeling some important advice.
I'm not entirely sure as I haven't read the specific 'The Changeling Novel'. But usually in such a novel, there would be the changeling character itself, perhaps a human who has been transformed. There might also be a mentor - like figure who helps the changeling understand their new state.
It could be Harry Potter himself still being a main character. He might be the one exploring the combination of magic and nen. Hermione would also likely be there, using her intelligence to figure out how nen works in the wizarding world. Ron might be involved too, perhaps struggling a bit more to adapt to the new nen concepts compared to the others.
It's hard to say without reading it, but it could be Harry, Hermione, and Ron. They are the central characters in the original series, so they might be the focus in this fanfic too.
In most teddy harry potter fanfic, Teddy Lupin is at the center. But other characters like Hermione Granger could also play important roles. Maybe she helps Teddy with his studies or gives him advice. And Ron Weasley could be there too, adding some humor to Teddy's adventures. Also, characters from Teddy's family, like his grandmother Andromeda, might be included to show his family background and support system.
Well, Harry Potter is most likely still one of the main characters. He would be the protagonist adapting to the new gaming - like situations in the fanfic.
I don't know for sure as I haven't read it, but it's likely to include some of the well - known 'Harry Potter' characters like Harry, Hermione, and Ron. Maybe it also has some original characters created specifically for this fanfic who interact with the main trio around the mystery of the ladder.
