There could be some new characters as well. Maybe a mysterious old wizard who lives near Harry's new secluded place. This wizard could either be a help or a hindrance to Harry's journey of self - discovery. Or perhaps a young Muggle - born wizard who befriends Harry in his new state of mind and shows him a different perspective on the wizarding and Muggle worlds.
Perhaps it's a story where Harry has been through so much trauma that he no longer cares about the things he used to value. He could be distancing himself from his friends like Ron and Hermione because he feels they don't really understand his new state of mind. This might lead to a rift in their relationships and a journey for Harry to find himself again.
Well, it could be Hermione. She might play a big role in trying to convince Harry to go or in dealing with the consequences of his not going.
There could be his friends like Ron and Hermione. Even though he hates everyone, they would still be important characters as they might try to figure out what's wrong with Harry and how to bring him back from this state of hating everyone.
There could be his drill sergeant, a tough and no - nonsense character who has to whip Harry into shape. Maybe there's a fellow recruit who becomes Harry's best friend. They could support each other through the difficult training.
Hermione would likely be there. She is always interested in learning, so she'd be involved in any study related to magical creatures. Ron might also be around, perhaps getting into some comical situations with the creatures. Hagrid is another obvious choice, as he has a deep love and knowledge of magical creatures.
Well, depending on what 'rq' stands for, it could be a group of original characters created for the fanfiction. Maybe there's a wise old wizard who takes Harry under his wing as part of this 'rq' upbringing.
Hermione would probably be there. She might be worried about Harry and trying to stop him from getting too close to the Whomping Willow at first, but then gets involved in the adventure too.
Hermione could be involved. She might suspect Daphne of having ulterior motives regarding Harry and try to warn him, which could play into the betrayal storyline in some way, either as a catalyst or as someone who helps Harry deal with the betrayal later.
Well, Hagrid would be a great addition. He could bring in some friendly magical creatures for the preschoolers to see, like baby owls or small unicorns. The kids would be thrilled to meet them.
Hermione would probably be involved. She's always by Harry's side, and she might be researching ways to help Harry tame the basilisk. Maybe she finds some useful spells or information in the library that gives Harry an edge.
