Their relationship might become stronger as they face new and strange challenges together in Forks. They would have to rely on each other more without the support of their usual wizarding friends.
Hermione's character might develop a more independent side. In Forks, without the constant presence of Hogwarts and her friends, she has to rely on herself more. She could become more self - assured in her decisions. Sirius, he might become more calm. The quiet of Forks could soothe his usually restless nature. He might find a new sense of purpose, perhaps in protecting the town in his own way.
One possible plot twist could be that they discover a hidden magical community in Forks. Since they are from the wizarding world, they might sense some strange magical energy there. Another twist could be that they get involved in a conflict between the local vampires and werewolves in Forks, using their magical skills to mediate or perhaps even take sides. Maybe they also find a way to combine magic with the unique properties of Forks, like the constant rain and the dense forest, to create new spells or potions.
Harry might become more reserved. In Forks, he's in a completely new environment. He may not want to draw too much attention to himself and his magical abilities. He could become more of an observer, which is different from his more action - oriented role in the wizarding world.
The story would change a great deal. Their presence would disrupt the existing power dynamics in Forks. For example, the vampires might view Harry's magic as a threat or an opportunity. And Remus' werewolf nature could either create an alliance or a conflict with the local werewolves.
The vampires in Forks would likely be very curious. They've probably never encountered witches like Hermione and Luna before. They might be initially cautious, seeing them as potential threats to their secrecy. The werewolves would also be on guard. However, some of the more open - minded locals, like Charlie Swan, might be friendly and just see them as two new, if a bit odd, girls in town.
Well, if Harry and Hermione move to Forks in fanfiction, it would be a very interesting crossover. They would bring their wizarding world knowledge and skills. Maybe they would try to keep their magic a secret from the locals at first. But eventually, they might use magic to improve the lives of the people in Forks, like helping with the local environment or something. And they could also form unique friendships with the characters from Forks, who would be very intrigued by their magical abilities.
In this type of fanfiction, it could be really interesting. Hermione's intelligence and magical skills from the wizarding world would contrast with the new environment in Forks. Draco, with his complex personality, would also have a lot to adjust to. Maybe they go there to start a new life away from the wizarding world's drama. They could encounter all sorts of new characters and situations that are unique to Forks, like dealing with the normal humans there while still having their magical abilities hidden.
It would become much more complex. Snape, who is usually a solitary and somewhat brooding character, would have to step up and be more involved. Ginny, being young and from a different generation, might expect different things from him. Their relationship would likely face a lot of external pressure from the wizarding community too.
A lot could happen. For starters, Hermione would likely try to find ways to blend in while also exploring the new place. She might befriend some locals and share her knowledge in a very discreet way. Draco would probably struggle more with the idea of living among Muggles. He might be a bit of a loner at first. But as time goes on, they could both get involved in the local community in different ways. Maybe they start a small business together, using Hermione's smarts and Draco's charm (in his own way).
It could be some traditionalist wizards who don't like the idea of Hermione and Teddy leaving the wizarding world and living among muggles. They might try to bring them back by force or create problems for them in Forks. Another possibility is some local dark forces in Forks that are threatened by Hermione's magic and Teddy's abilities.
