It could be about Harry's daily life at Hogwarts, his adventures that are unique to living there, like exploring hidden passages at night or having impromptu magic lessons with his friends in the common room.
Dumbledore could also be a major character. As the headmaster of Hogwarts, he has a big influence on Harry's life at the school. And maybe some of the Hogwarts ghosts like Nearly Headless Nick would play significant roles in the story as well.
It's also likely that Harry, having faced so much darkness, decides to take a break from the wizarding world for a while. Fleur, on the other hand, is still very much involved in the magical community. She might persuade Harry to come back and they start to explore different magical cultures together. They could travel to far - flung places, discover new spells and magical creatures, and in the process, their relationship blossoms.
Well, without reading it specifically, it could be about Harry having the role of a mediwizard at Hogwarts. Maybe he's using his skills to heal students or deal with magical maladies in the school. It could also involve his adventures while being in this new role, like facing some mysterious magical illnesses that no one has ever seen before.
In this fanfiction, it might be about Harry Potter's new life in Potter Manor. It could include his exploration of the manor, perhaps finding secrets within its walls. He may also have new relationships or experiences that are unique to this setting.
I'm not sure specifically as I haven't read that exact fanfiction. But it might be a story where Harry Potter somehow ends up on Naboo (from the Star Wars universe) and has all sorts of adventures there. Maybe he uses his magic in a world that's very different from the wizarding world he's used to.
In some fanfictions, Harry might discover that students at Hogwarts are being abused by certain dark forces or corrupt individuals. For example, there could be a fanfic where a new dark wizard has infiltrated the school and is using dark magic to mentally or physically abuse students. Harry could discover this through seeing the strange behavior of the victims or finding some clues around the school.
Well, it could be that Harry as headmaster has to deal with a new generation of students who idolize him. He would have to balance being a role model and an authority figure. Maybe there would be a plot where some students try to use his name to get away with rule - breaking, and he has to set them straight. Also, he could start new Quidditch traditions or tournaments to boost school spirit.
One consequence could be that it alerts all the magical defenses of Hogwarts. This means that every protective spell, charm, and enchantment within the castle would be on high alert. For example, the portraits might become more vigilant, the secret passages might close off more tightly, and the ghosts could be more active in patrolling the corridors.
Yes, it is possible. Fanfiction allows for creative reinterpretations of established universes. In this case, imagining Harry Potter as the founder of Hogwarts could lead to some really interesting storylines. It could explore how his modern - day knowledge and experiences would shape the school in its earliest days, perhaps introducing new spells or ways of teaching that are different from what we know of the original founders.
In a lockdown at Hogwarts, there could be a fanfic where some students try to break the rules and explore the restricted areas of the castle. They might think there's some hidden magic or mystery that can solve the lockdown situation. For example, they could suspect that a certain secret passage holds the key to ending the lockdown.
