A possible fanfiction could be that Dumbledore owns a magical artifact shop in Diagon Alley. The items in the shop have their own histories and powers. Harry and his friends might visit the shop and discover something that is crucial for their fight against Voldemort, like a weapon or a protective charm.
There is a really interesting fanfiction where Dumbledore owns a house - elf training center. He believes in treating house - elves with respect and dignity and wants to give them proper education. Through this center, we see a different side of the wizard - house - elf relationship and how Dumbledore is trying to change the traditional norms.
One example could be those where Dumbledore is portrayed as having hidden motives that are not in the best interest of Harry or Hogwarts. In some fanfictions, he might be shown as being overly manipulative in his actions towards Harry, like using him as a pawn in a bigger game against Voldemort without fully considering Harry's well - being. However, it's important to note that these are just creative interpretations in the world of fanfiction and not the official view of the character from the original books.
One interesting Charon fanfiction could be about his backstory. Maybe it delves into how he came to be the ferryman of the dead in the wizarding world. It could explore his relationship with other magical beings in the underworld.
There might be a fanfiction where Hestia has a special magical ability that was never revealed in the books. For example, she could have the power to communicate with magical creatures in a unique way and uses this ability to gather intelligence for the Order of the Phoenix. It could also focus on her backstory, like where she came from and how she got involved with the wizarding world.
One could be a story where Dumbledore is magically thrust into Harry's mind during a crucial battle. In this fanfiction, Dumbledore's wisdom and magical power help Harry make strategic decisions that he might not have made otherwise. It could be an exciting read as it combines the two powerful characters in a very unique way.
Honestly, this is a very specific and not so common idea for a fanfiction. While there are countless Harry Potter fanfictions out there exploring all kinds of relationships and scenarios, this one might be a bit hard to find. You might have to sift through a lot of different stories on fanfiction platforms. Some might be more focused on their mentor - mentee relationship and use the term in a more symbolic way, like Harry being in a position where he has to balance between Dumbledore's teachings and his own instincts, which could be loosely related to the'straddling' concept.
There's 'Dumbledore's Special Training for Harry' which focuses on combat training. Harry learns advanced dueling techniques from Dumbledore, which comes in handy when facing powerful dark wizards. It also shows how Dumbledore prepares Harry for the greater challenges that lie ahead in the wizarding world.
Well, a great fanfiction in this genre is 'Dumbledore's Manipulative Ways Revealed'. In this story, it really shows how Dumbledore's actions, like sending Harry back to the Dursleys every year, could be seen as manipulative. He might have been trying to keep Harry in a state of vulnerability for some reason. Another one is 'Harry and Dumbledore's Complicated Relationship' which focuses on how Harry slowly realizes that Dumbledore may not be as pure - hearted as he initially thought. And 'Behind Dumbledore's Schemes' is also interesting as it uncovers the possible motives behind his manipulative behavior.
Some fanfictions focus on Dumbledore's mistakes in raising Harry. They might show that his distance and secrecy were not just for protection but rather a sign of his lack of true care. For example, in a particular fanfic, Dumbledore is blamed for not being more forthcoming with information about Harry's parents and the prophecy, which leads to Harry making many mistakes and facing more danger than necessary.
There could be a fanfiction where Harry Potter, as a powerful wizard, unknowingly has vassals among the students at Hogwarts. These vassals might be those who look up to him and are willing to follow his lead. They could assist him in his adventures, like when he's facing the new threats that emerge after the fall of Voldemort. This could add a new layer of complexity to the relationships within the school.
