The plot could revolve around Harry being 2000 years old and having to adapt to the modern wizarding world. He has seen so many changes in magic and society. He might struggle with modern technology in the wizarding world while also trying to pass on his ancient knowledge to the new generation. There could be a conflict where some people want to use his knowledge for wrong purposes and he has to protect it.
It could change the entire timeline. For instance, the events that happened in the original story might be just a small part of a much larger, millennia - long history. Characters' motives and actions could be re - evaluated in the context of this long - term view.
Well, it could be. In the normal Harry Potter universe, we have a set timeline. But in fanfiction, anything goes. This concept might bring in new elements such as ancient magic that was lost over time and how Harry, being 2000 years old, has seen the rise and fall of different magical cultures. It's definitely not something you see in the original books.
Well, in this type of fanfiction, Harry could go back and redo the seven years with a different approach. He may decide to be more open about his experiences with Voldemort right from the first year. This would lead to Dumbledore taking different actions and perhaps training Harry more intensively in magic. Also, Harry could use his knowledge to help his friends like Hermione and Ron develop their magical abilities faster. He could also try to change the way the wizarding world views half - bloods and Muggle - borns, starting from his early years at Hogwarts, which would have a big impact on the overall story.
The plot could involve a situation where a new form of dark magic is unleashed in the wizarding world, which spreads like wildfire and causes destruction similar to 911. The Ministry of Magic is caught off - guard. Hermione, with her vast knowledge, starts researching a way to counter this magic. Meanwhile, Ron and Harry lead the effort to protect the civilians. They set up shelters in places like the Room of Requirement and use Patronuses to guide people to safety. As they dig deeper, they discover that this dark magic was a planned attack by a long - hidden dark wizard group who wants to take over the wizarding world.
In this fanfic, Harry Potter could be raising the first - years in a way that involves preparing them for the wizarding world outside of Hogwarts. He might introduce them to different magical creatures, not just the ones they study in class. He could also be mentoring them in how to deal with the politics and rivalries within the wizarding community. This would include teaching them how to handle encounters with Slytherins who may not always be friendly, and how to build bridges across house divides, just as he did during his time at Hogwarts.
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.
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.
Well, it might not be entirely new. There are always various wild and creative ideas in the fanfiction world. However, the idea of Harry Potter being thousands of years old is quite distinct. It could potentially add a whole new layer of mystery and history to the familiar story. For example, it could change the relationships between characters and how magic has been passed down through the ages.
Maybe it could be an ancient magical being like a centaur. Centaurs are known for their knowledge of the stars and ancient magic. They might take Harry under their wing and teach him old magic that has been passed down through their generations.
Maybe Harry could be the host of the Kyuubi's power in the wizarding world. He would have to deal with not only the threats from Voldemort but also the power of the Kyuubi inside him. His friends might be both amazed and a bit scared of this new power source.
