Well, perhaps in this fanfiction, they might fix the future by changing the way Hogwarts educates its students. For example, adding more practical and modern magic classes. This could lead to a new generation of wizards who are better equipped to face future threats. Also, they could rewrite history to ensure that certain characters don't turn to the dark side, like by providing more support to those at risk early on.
One idea could be that the characters find a way to prevent certain dark magic spells from ever being created. This would change the future by reducing the power of the dark wizards. Another could be that they manage to unite the wizarding world and Muggle world earlier, thus avoiding future conflicts.
Perhaps a story where the magical world is trying to integrate more with the non - magical world in the future. Harry Potter's kids could be at the forefront of this movement, dealing with both the excitement and the challenges that come with it. There could be political intrigue as some wizards oppose this integration.
A plot idea could be that the Time - Turner in Harry Potter is actually an ancient magical version of the Flux Capacitor. Hermione discovers this connection while researching in the library. She then tries to build a device that can combine the two technologies. This leads to her accidentally traveling to the Back to the Future universe. There, she meets Marty McFly and they have to work together to fix the time rift that her experiment created.
In the 'female harry potter reading the future fanfiction', there could be a plot where she reads about a future full of technological advancements in the wizarding world. For example, new spells are developed using some form of magical technology. She might also read about a future where her friends have different fates. Hermione could be leading a research project on ancient magic, while Ron is in charge of a new Quidditch league. And she has to decide if she wants to be part of these new developments or go her own way.
Perhaps in the fanfiction, Neville discovers a new form of magic that can heal the damage done to the Forbidden Forest during the battles. He shares this knowledge with others, and together they restore the forest to its former glory. This not only helps the magical creatures that live there but also has a positive impact on the overall environment of the wizarding world, contributing to a better future.
Harry Potter himself would probably be a main character. After all, he's the hero of the original series and would likely be at the center of any attempt to fix the future. Hermione Granger would also be a key figure, with her intelligence and knowledge of magic.
You could write about the next generation of Hogwarts students facing a completely different kind of threat than Voldemort. Maybe an inter - dimensional invasion that requires them to learn magic from other magical cultures. This would involve a lot of world - building and creating new magical species and cultures. It could also show how the old traditions of Hogwarts adapt to this new threat.
A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.
One idea could be that Harry and Hermione find a time - turning device. They use it to go back and change key events in the wizarding war. For example, they might prevent Cedric's death, which could have a huge impact on the future of Hogwarts and the wizarding world.
One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.
To fix the story in Harry Potter fanfiction, you might need to focus on the pacing. Some fanfictions tend to rush through important events or drag out uninteresting parts. Make sure that the build - up to major events, like a big battle or a revelation, is gradual and exciting. Another aspect is the world - building. If the fanfiction is set in Hogwarts or the wizarding world, it should feel like the same world as in the books. This means including details such as the different houses, classes, and magical creatures in a believable way.
