Another plotline could involve Hermione trying to redeem Rowle. She could see some good in him despite his actions and attempt to turn him away from the dark side. This might include showing him the positive aspects of the wizarding world that don't involve dark magic.
Rowle is another main character. He's usually a dark wizard, so in this fanfiction, he could be a complex character with his own motives and backstory that Hermione has to deal with.
One great Hermione and Rowle fanfiction is 'The Unlikely Alliance'. It explores an alternative universe where Hermione and Rowle are forced to work together on a dangerous mission. Their initial distrust gradually turns into mutual respect as they face numerous challenges. Another interesting one is 'Rowle's Redemption'. In this story, Rowle has a change of heart due to Hermione's influence and they end up on a path of changing the wizarding world for the better.
She could save him by appealing to his better nature. Hermione is known for her intelligence and ability to reason. So, she might talk to Thorfinn Rowle, convince him to turn away from whatever dark path he was on that put him in danger in the first place. By showing him an alternative way, she could in a sense'save' him from his own self - destructive actions.
One common theme is the idea of redemption. Often, Rowle is depicted as a character in need of redemption, and Hermione plays a role in that process. For example, she might help him see the error of his ways.
He could be into the ones that focus on Hermione's academic achievements. Maybe stories where she discovers new spells or makes great contributions to the wizarding world's knowledge.
Maybe he's attracted to the unique interpretations of Hermione's character in the fanfiction. Different fanfictions might show different sides of her, like her intelligence in new and exciting ways.
Some fanfictions explore a different relationship dynamic between them. Maybe Harry has a problem that only Hermione can understand and help him with, and this brings them closer in a way that's different from their normal friendship. It could be something related to his connection with Voldemort or his family history.
One interesting plotline could be Hermione's journey of self - discovery within the pack. Maybe she discovers new magical abilities or a deeper understanding of her own strength as she interacts with the pack members.
One interesting plotline could be Hermione's struggle to hide her maledictus condition from her friends at Hogwarts. She might constantly worry about turning into the beast associated with the curse and how it could endanger those around her.
One possible plotline could be Hermione trying to find a way to break the curse on her own. She might use her vast knowledge of magic from the library. Another could be her friends, like Harry and Ron, going on a dangerous quest to find the antidote for the curse. And perhaps there's a plotline where the curse has some unforeseen side effects that change her relationships with other characters.
