Perhaps there is a magical object that was created by Salazar Slytherin and Hermione is the only one who can figure out how to unlock its power. Along the way, she starts to have visions of Slytherin's past and his intentions for Hogwarts. She then has to decide if she should use the object's power for the good of the school or keep it locked away to prevent any potential misuse.
One plot idea could be that Hermione discovers a long - lost spellbook of Salazar Slytherin. As she delves into it, she starts to understand his view of magic in a new way. Maybe the spells in the book are different from what she has learned before, and she has to struggle with whether to use them or not, given Slytherin's somewhat dark reputation.
A possible plot could involve a time - travel scenario. Hermione goes back in time and meets Salazar Slytherin. She tries to change his views on muggle - borns by showing him the great things that muggle - born wizards can do. This would create a really interesting dynamic as she challenges his old - fashioned beliefs.
One reason could be her thirst for knowledge. Slytherin was known for his cunning and knowledge of magic. Hermione might be drawn to his intellectual side. Another reason could be a desire to break the traditional house rivalries. By becoming a fan of Slytherin, she could promote unity among the houses.
Maybe Harry time - travels back to the time of Salazar Slytherin. He has to navigate the complex politics and magic of that era. He might end up befriending Slytherin and changing the course of Hogwarts' history. This could lead to a Hogwarts that is different in many ways, like having a more unified house system earlier on.
Yes, there are likely some fanfictions out there. In the Harry Potter universe, Hermione is a Gryffindor, but fanfiction often likes to play with the idea of characters having different allegiances or interests. Some writers might explore a scenario where Hermione has an unexpected admiration for Salazar Slytherin, perhaps delving into the history and values of Slytherin house that she could potentially respect, despite the traditional Gryffindor - Slytherin rivalry.
Perhaps in a parallel universe, the Hogwarts founders had different relationships. Hermione discovers this parallel world where she and Salazar are destined to be together. She has to fight against the norms of both worlds to be with him. This could involve battles against traditional pure - blood ideas in Slytherin's world and modern prejudices in her own world.
A plot could involve Slytherin Hermione and Harry being paired for a long - term project by a teacher who wants to encourage inter - house cooperation. At first, they struggle because of their different house values, but gradually they find common ground. For example, Hermione's Slytherin cunning helps them outwit some bullies who are trying to steal their project ideas, and Harry's Gryffindor courage gives Hermione the push she needs to stand up to some of the more elitist Slytherins who look down on her for her non - pure - blood status. Or perhaps they discover a hidden prophecy that only they can understand together, and it has something to do with a new threat to Hogwarts that combines elements of both Slytherin's ambition and Gryffindor's heroism.
One idea could be Hermione using her intelligence to change the Slytherin house's reputation from within. She could start study groups that include students from all houses, gradually breaking down the traditional rivalries. Another plot could involve her befriending some of the more misunderstood Slytherin students and together they work on a secret project that benefits the whole school.
A possible plot is that Draco, who is in Slytherin, discovers a hidden secret about Hermione's family that has ties to Slytherin. This makes him see her in a new light and they start to form an unlikely alliance. They could then face challenges from their respective houses. Another plot idea is that in an alternate universe, Hermione is sorted into Slytherin and she and Draco become friends and then something more, as they strive to change the negative perception of Slytherin from within.
Hermione could be developed by having her gain some of Slytherin's traits, like his cunning and resourcefulness, in a way that doesn't compromise her Gryffindor values. She could use these new - found traits to solve problems in Hogwarts. Salazar Slytherin's character could be developed by making him more relatable. For example, if he had a love interest in the past that influenced his views, and Hermione discovers this through her research in the fanfiction.
A plot could involve FemHarry having a special connection to an ancient magical artifact that Hermione helps her research. As they dig deeper, they find out it has the power to change the wizarding world. They then have to protect it from dark wizards who want to use it for evil. This would lead to a lot of action and suspense.
Well, a plot might be that Hermione is deaged due to a magical accident in the library. As a deaged Hermione, she has a different view on things. She might start to question the rules of Hogwarts more, as she doesn't have the same level of respect for them as her older self. Her friends, Harry and Ron, would have to deal with this new, more rebellious Hermione while also trying to figure out how to reverse the deaging spell. This could cause a lot of chaos in Hogwarts.
