Well, Harry Potter is likely to be one of the main characters. He's always been an important part of Hermione's life in the original series, and in this fanfic, he might play a crucial role in the events related to the Half - Blood Prince. Maybe he and Hermione are on a joint mission to uncover the secrets of the Half - Blood Prince.
In many fanfictions, Hermione Granger's family plays important roles. Her parents, who are dentists in the original series, might be depicted with more magical involvements in fan stories. For example, some fanfictions could explore how her parents adjust to the wizarding world after Hermione reveals her magical abilities to them more fully. This can add new dimensions to Hermione's character as well, as her family background and their relationship can shape her actions and decisions within the fan - created plots.
A notable one is 'Werewolf Encounters with Hermione'. This fanfiction delves into the magical politics surrounding werewolves and Hermione's role in it. It's a long - form story that gradually unfolds, with Hermione using her intelligence to navigate the complex situation. The author does a good job of integrating werewolf lore into the wizarding world we know from the original series.
In a fanfic, Hermione could be invited to a special event at Beauxbatons. She gets to see the beautiful architecture and unique magical practices of the school. There, she meets a Beauxbatons student who becomes her study partner. Together, they explore different ways of magic and Hermione brings some of her Hogwarts knowledge to share, creating a story of cross - school cooperation.
It differs mainly in the role assigned to Hermione. In most other fanfictions, she is often depicted as a heroic figure or a brilliant student. Here, as a 'house slave', her focus is more on the domestic aspects of the wizarding world, which is quite different from her typical roles.
Well, another option could be to ask in relevant fan communities. For example, on Reddit, there are subreddits dedicated to Harry Potter fanfiction. Post a request there asking for fanfiction about Mr Granger and his daughter Hermione. People in those communities are usually quite helpful and might be able to point you to some great stories.
There could also be themes related to the wizard - Muggle divide. Mr Granger, being a Muggle, might have some unique perspectives on the wizarding world that he wants Hermione to consider. This could lead to stories where Hermione has to navigate between the two worlds, trying to bridge the gap in some way. Maybe Mr Granger wants Hermione to bring some of the positive aspects of the wizarding world back to the Muggle world, or he might be worried about how the wizarding world could change his daughter in ways he doesn't understand.
In the fanfiction, it might be shown through Snape secretly watching over Hermione during dangerous situations. For example, in a battle or when she's being harassed by other students who are prejudiced against Muggle - borns.
In such fanfictions, we might see Hermione having a different kind of connection to knowledge. Since Athena is the goddess of wisdom, Hermione could have an even deeper understanding of magic and its history. For example, she might be able to decipher ancient spells more easily or have insights into the origins of magic that others don't. This could also change her relationships with her friends. She might become more of a leader, guiding Harry and Ron with her enhanced wisdom.
One idea could be that Hermione turns into a centaur as a result of a misfired spell during a Defense Against the Dark Arts class. She could then struggle to adapt to her new form, having to deal with the physical differences like running on four legs and having a horse - like body. Meanwhile, her friends Harry and Ron would be trying to find a way to reverse the spell.
