Fanfiction often creates new characters, places, and spells. It can explore different corners of the wizarding world that J.K. Rowling didn't fully cover in the original books. For example, it might focus on a small wizarding village in Scotland that was only briefly mentioned. Writers of fanfiction can also expand on the magic system, perhaps creating new types of magic related to nature or emotions. This way, it gives readers a broader view of the magical universe.
