Well, in some fanfictions, there are backstories for minor characters. For instance, the story of the house - elves at Hogwarts. How they came to serve the school, their own little hierarchies, and perhaps a backstory of Dobby's family. Also, there could be a backstory about the origin of the Forbidden Forest, like if it was created by an ancient magic long ago and what secrets it holds that are not known in the original books.
There are fanfictions that explore the backstory of the Weasley family's connection to magic. Maybe they have a long - lost relative who was a great wizard but was shunned for some reason. And then there's the backstory of the Dark Arts at Hogwarts. How certain spells came to be considered Dark, and who were the first wizards to study and misuse them. It could also include how Hogwarts has been trying to combat the spread of Dark Magic over the centuries.
Yes, 'The Founders' Tales' is a great fanfiction that delves into the backstories of the four founders. It shows how they met, what their initial ideas for Hogwarts were, and how they overcame differences in their magic beliefs. Another one is 'Hogwarts: The Beginning' which details the challenges they faced while building the school and choosing students.
One idea could be creating a character who is a muggle - born witch or wizard but has an extraordinary talent for a very rare form of magic, like time - traveling magic. Another idea is a character who is a half - giant on their mother's side and has to deal with the prejudices at Hogwarts. Or perhaps a character who is a descendant of one of the founders of Hogwarts but has been kept in the dark about their heritage until they arrive at the school.
One possibility is that it could be a result of some powerful magic gone wrong. Maybe she was involved in a spell that was supposed to do something else but ended up changing her hair color to white. It could also be a sign of her having a special connection to an ancient magic that is associated with white - haired beings in the wizarding world.
Perhaps the original family had a hidden treasure or a powerful magical artifact. In the fanfiction, Harry and his friends could go on a quest to find it. Along the way, they discover that the original family had ties to other magical creatures, like centaurs or merpeople, and these relationships are crucial in unlocking the location and power of the artifact.
Another type could be an OC who is a transfer student from a different magical school. This character could bring new spells and cultural aspects of magic to Hogwarts. They might have to adapt to the different houses and rivalries while also forming strong friendships with the likes of Harry, Hermione, and Ron.
Well, perhaps it could explore alternative universes where Harry isn't a Potter at all. It might change the whole dynamic of the story, like his relationships with other characters. For example, without the Potter name, his connection with Snape could be entirely different, as Snape's animosity towards Harry was partly due to his father being James Potter.
There's a character in some fanfictions called Lyra, a half - veela who has the power to control emotions. She becomes Harry's love interest and her powers often come in handy during battles. Another interesting one is Orion, a powerful wizard who was once a student at Hogwarts but was banished for trying to expose a dark secret within the school. He returns to help Harry in his fight against Voldemort.
There's often a character who is a powerful but mysterious new transfer student. This character usually has a unique magical ability that catches everyone's attention. Another interesting type is the long - lost relative of a main character. For example, a long - lost Potter cousin who shows up with some secrets. And sometimes there are characters who are self - taught wizards from the Muggle world, bringing a different perspective to the wizarding community.
In Harry Potter fanfiction, 'bridges' could refer to literal bridges like the ones in Hogwarts grounds. For example, the bridge over the lake might be a setting for some fan - created adventures. Maybe a character discovers a hidden passage under the bridge that leads to a secret area.
One interesting Harry Potter fanfiction could be about an alternate universe where Harry is sorted into Slytherin. This changes his whole dynamic as he has to navigate the house known for its cunning while still having his moral compass intact. Another might be a story where Hermione discovers a new branch of magic that has been long forgotten, and she uses it to solve a mystery in Hogwarts. There are also those that explore the backstories of minor characters, like Neville's grandmother and her adventures during her time at Hogwarts.
