Yes, it can be. Many fanfiction writers like to explore unique perspectives, and having Hogwarts as an observer or an active part in Harry's life stories can be very appealing. It allows for a different take on the familiar storylines.
In the world of Harry Potter, Hogwarts is a school, not a sentient being that can 'watch' fanfiction. However, students at Hogwarts might be interested in reading or writing Harry fanfiction as a form of creative expression related to their magical world.
It could be a very creative and interesting concept. Maybe it represents the idea of the magical world of Hogwarts being an observer or a kind of inspiration for the fan - created stories in Harry Potter fanfiction. It might imply that the essence of Hogwarts, its characters, and its magic are so strong that they seem to 'watch over' the various interpretations and stories written by fans.
I haven't come across any myself. But the world of fanfiction is so huge that there could potentially be some out there. You should search for it on fanfiction platforms.
I'm not entirely sure about fanfictions specifically where Hogwarts watches AVPs. However, there are many great Harry Potter fanfictions out there. You could start by looking on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Try searching for unique crossovers or alternate universe stories that might have an interesting take on Hogwarts and the characters.
Fanfictions about Hogwarts watching Potter family memories can also attract new fans to the Harry Potter fandom. People who are interested in family - centric stories or those who like the idea of exploring hidden histories within a magical world may be drawn to these fanfictions. Once they start reading, they may become more interested in the overall Harry Potter franchise, thus contributing to the growth and continued popularity of the fandom.
One interesting aspect could be the unique interpretations of the characters. Since it's fanfiction, the author might show a different side of the Hogwarts students. For example, they could explore how the characters react to the events in 'A Very Potter Musical' in ways that the original source didn't. Another aspect could be the new storylines that are created. It might introduce new magical elements or relationships within the Hogwarts setting that add depth to the 'Potter' universe.
He might also be a bit confused at times. Some fanfictions deviate a lot from the real events in his life. For example, if there's a fanfiction where he has a completely different upbringing, it would be strange for him to read about. He could also feel a sense of flattery that so many people are interested in his story and want to create their own versions of it.
It contributes by adding new stories. Fans are always hungry for more content, and this fanfiction gives them exactly that. It keeps the Potter world alive in different ways.
In the fanfiction world, Harry might be the heir to Hogwarts if there was some sort of magical pact made generations ago. For example, perhaps one of his ancestors had a special role in the creation or protection of Hogwarts, and this role was passed down through the family. It could also be that his unique magical abilities, like his ability to resist Voldemort's attacks from a young age, are signs of a deeper connection to Hogwarts itself. This connection could be what designates him as the heir in the fanfiction's plot.
