If Hermione was Dumbledore's granddaughter in fanfiction, it would likely make her an even more important figure at Hogwarts. The teachers might treat her differently, perhaps with more respect or higher expectations. And she could have a different role in the Order of the Phoenix too, being related to Dumbledore. She might be given more dangerous or important tasks.
Well, if Hermione were Grindelwald's granddaughter in a fanfiction, it could completely change the power dynamics. Hermione's intelligence might be seen as a legacy from Grindelwald. Maybe she would have some hidden, dark magical abilities that she has to struggle with. This could also put her in a difficult position with her friends, especially Harry and Ron, as they've been fighting against Grindelwald's ideology. It would add a whole new layer of conflict and self - discovery for Hermione.
One possible plot could be that Hermione starts having strange dreams or visions that lead her to discover a hidden family connection to Merlin. She then embarks on a journey to learn more about her heritage, which takes her to ancient magical places and uncovers long - lost spells or powers related to Merlin.
It would change a great deal. First off, McGonagall would probably be more involved in Hermione's academic progress on a personal level. She might give her special assignments or extra tutoring. As for the other professors, they might view Hermione as having an 'inside track'. For instance, Professor Flitwick could be more lenient with her in Charms class. This new dynamic would add a whole new layer to Hermione's Hogwarts experience and how she interacts with the faculty.
One possible plot could be that Hermione discovers a hidden family secret that reveals she is Dumbledore's sister. This leads to her having access to new knowledge and powers that Dumbledore left for her, which she uses to fight a new dark force in the wizarding world.
Perhaps she could have a special connection to the magic of Hogwarts itself, just like Dumbledore did. So she could be able to control certain aspects of the castle that others can't, like opening secret passages more easily or sensing when something is wrong within the school's wards.
One way it could develop is if Dumbledore withholds important information from Hermione about her family or her own magical abilities. He might do this because he fears she will use that knowledge in a way that could disrupt his grand plan for the wizarding world. For instance, Hermione discovers she has a special power that could defeat Voldemort easily, but Dumbledore has kept it from her all along, making her feel extremely betrayed as she could have saved many lives if she knew earlier.
Sure. There's a whole world of fanfiction out there, and the concept of Hermione being Merlin's granddaughter is an interesting one that could attract many writers. It could involve stories where Hermione discovers her relation to Merlin through some ancient magic or a hidden family secret. This could lead to all sorts of new plotlines and character developments within the fanfiction.
Dumbledore might be motivated by his over - arching plan to defeat Voldemort. He could see Hermione as a sacrifice that needs to be made. Maybe he believes that by betraying her, he can gain some crucial information from the enemy that will ultimately lead to Voldemort's downfall.
If Hermione was born in the Marauders era in fanfiction, it would be really interesting. Maybe she could use her knowledge of magic, which is quite advanced even for her own time, to help the Marauders in their pranks and also in more serious matters. She might be able to influence the way they deal with Snape, for example. And who knows, she could even be the one to discover some of the secrets that the Marauders had, like how to become Animagi, and use that knowledge to their advantage.
Well, if Hermione was a spy for the Dark Lord, it would completely turn the story upside down. For one, the trio's dynamic would be shattered. Harry and Ron would be in great danger as Hermione could pass on all their plans to Voldemort. Hogwarts would no longer be a safe haven as she could leak information about its defenses. And the final battle might not even happen in the way it did in the original, because with Hermione on the Dark Lord's side, he would have a much greater advantage in terms of intelligence and strategy.
