Their view might expand. They'd see different takes on the wizarding world that they hadn't considered before.
The Weasleys have their own traditional view of the wizarding world. Reading fanfiction could introduce them to new magical concepts, different relationships between characters, and alternative storylines. For example, if a fanfiction focuses on a more inclusive wizarding society, it could make them think about the exclusivity in their own world. Or if it shows different ways of using magic, it might inspire them to experiment more. Ginny, being a young and open - minded witch, could be more receptive to these new ideas and might even try to bring some of the positive changes she reads about into her own life at Hogwarts. The twins could see new business opportunities in the fanfiction - inspired magical items or services. Ron, on the other hand, might be more hesitant, but still might be influenced in his thinking about his friendship with Harry and Hermione.
The Weasleys' understanding could be both broadened and a bit muddled. On one hand, they might see new interpretations of old magic or different ways characters could have interacted. For example, if the fanfiction explored a different side of Snape's actions in Book 6, it could make them think. But on the other hand, they might be confused as some fanfictions can be really out - there. They'd have to sort through what was based on real knowledge of the wizarding world and what was pure imagination.
Their view could become more confused. Fanfiction can present all sorts of alternate universes and character developments. The Death Eaters, used to a very specific view of the wizarding world under Voldemort, would find it hard to accept different versions. They might see the wizarding world in fanfiction as a chaotic and wrong place, which would make them double down on their own views to feel more secure.
It might not change at all. They are so closed - off to the idea of magic that even fanfiction about it would seem like pure fantasy to them.
His view could become more open - minded. He'd realize there are other ways to approach the supernatural world. For example, the way the hunters in Supernatural use weapons instead of wands might make him think about alternative forms of magic defense.
Their view could be altered in multiple ways. If the fanfiction presents different moral stances regarding the Deathly Hallows, they might start to reevaluate their own views. For instance, if a fanfic has a character using the Hallows for evil in a way they hadn't thought of, it could make them think about how to better safeguard against such misuses. Also, seeing how modern fans imagine the Hallows' impact on relationships could make them consider the social aspects of magic more deeply.
After reading the fanfiction, Percy could have a more in - depth understanding of the wizarding world. He might start to think about how the social structure in the wizarding world compares to that in his demigod world. He might also be more curious about the history and lore of the wizarding world, and how it developed compared to his own world of Greek gods and monsters. He could even start to imagine what it would be like to be a wizard, with all the unique spells and magical items, and how that would change his approach to dealing with his own problems.
The wizarding world would likely be plunged into a state of despair. Harry was seen as the 'Chosen One' to defeat Voldemort, so without him, there would be a sense of hopelessness. Voldemort would probably have free rein to impose his dark rule without much opposition at first.
The wizarding world would become more open to Muggle - borns. Harry being a Muggle - born advocate would ensure that there are no discriminatory practices against them. He might also make Hogwarts more accessible to students from all backgrounds, not just those with a magical family history.
In fanfiction, Harry Potter can change the Wizarding World in many ways. For example, he might introduce new spells or magical concepts that were not in the original series. He could also have different relationships with other characters, which in turn would affect the social dynamics of the Wizarding World.
They may gain a deeper understanding of how the outside world perceives their world. Fanfiction often reflects the hopes, dreams, and fears that fans have about the wizarding world. So, by reading it, the Potter family can get a sense of what others find interesting or concerning about their world. For instance, if a lot of fanfiction focuses on the social inequalities in the wizarding world, it might make them more aware of these issues and perhaps even inspire them to do something about it.
