In some fanfictions, Harry might become a very influential Auror, traveling around the wizarding world to fight dark magic remnants. He could also be involved in reforming the Ministry of Magic, ensuring fairness and equality for all magical beings.
In other fanfictions, new relationships might form. For example, Harry could develop a deep friendship with some of the children of his former enemies. This shows how the wizarding world is trying to heal and move forward. Also, his relationship with Hermione and Ron might evolve in different ways, such as going on new adventures together as a trio even in their later years.
It could be about Harry, Ron and Hermione's careers. Maybe Harry is now a high - ranking Auror, leading teams to fight the remaining dark wizards. Ron could be running Weasley's Wizard Wheezes successfully, and Hermione might be making great changes in the Ministry of Magic with her intelligence.
The main characters are often the children of the original Harry Potter characters. For example, Albus Severus Potter, James Potter, and Lily Potter. Also, Scorpius Malfoy is usually a central character as he is part of the new generation at Hogwarts.
One interesting story could be about the next generation of Hogwarts students facing a new dark threat that the original characters have to help them with. It might involve new spells and magical creatures.
In '19 years later' in Harry Potter fanfiction, we might see the next generation of wizards at Hogwarts. Harry's kids could be getting into all sorts of adventures, just like he did. Maybe they'd be facing new threats to the wizarding world.
It depends on how you look at it. Fanfiction is a place for creativity to run wild. While creating life in a Harry Potter fanfic might not be something J.K. Rowling would do in the official series, in the fan world, if it's done in a way that respects the characters and the overall tone of the story, it can be okay. For example, if it's a magical experiment gone wrong or right in a way that still ties into the magical laws of the Potterverse, it could be an exciting addition to the story.
In most cases, it is legal. Fanfiction is often considered a form of derivative work. As long as it doesn't violate J.K. Rowling's copyright in extreme ways, such as mass - producing and selling it without permission. Many fans create fanfiction as a way to explore different aspects of the Harry Potter universe, and the general reading of it for personal enjoyment is usually okay.
One lesson could be about friendship. In many Harry Potter fanfictions, just like in the original books, characters rely on their friends. They face challenges together and learn that true friends are there through thick and thin. For example, they might help each other study magic or fight against dark forces. This shows that in real life, having good friends is crucial for support and growth.
