A plot could be about a new student who arrives at Hogwarts just as Hermione is petrified. This new student has some special knowledge or ability related to the petrification curse. They team up with Harry and Ron to figure out how to save Hermione and also discover that the new student has a connection to the one who cast the spell in the first place. Maybe they find out that the new student's family has a feud with the heir of Slytherin.
The fanfic could focus on Hermione's state while petrified. What she is actually experiencing inside. Maybe she can still perceive the world around her in a limited way. She could be trying to communicate with the others through her thoughts or some sort of magic that she discovers while petrified. This could lead to a whole new level of mystery and adventure as the others try to figure out how to receive her messages.
A possible plot is that a spell gone wrong makes Queen's music the only thing that can calm a dangerous magical creature. Hermione, being the clever witch she is, uses her love for Queen to figure out how to tame the creature and in the process, she also uncovers a long - lost magical connection between Queen's music and ancient wizarding magic.
One idea could be a time - travel plot where Hermione goes back in time and teams up with a young Dumbledore to solve a mystery that has implications for the future of Hogwarts. Another could be a story where Dumbledore entrusts Hermione with a special mission that no one else in the wizarding world can handle due to her unique skills and knowledge. Maybe a plot where Hermione discovers a long - lost spell in the Hogwarts library that was created by Dumbledore in his youth, and she has to figure out how to use it to save the school from a new dark threat.
A plot could revolve around Viktor inviting Hermione to visit his home country to learn about a different kind of magic.

For example, they might encounter a local magical creature that only they can figure out how to deal with. And through this adventure, their relationship blossoms.
How about a fanfiction where the petrification spreads a strange magic across Hogwarts? As Harry and Hermione are petrified, their magic starts to seep out and affect the castle and its inhabitants in strange ways. The other students then have to deal with these magical anomalies while trying to find a cure for their friends.
One plot idea could be Hermione facing discrimination within the wizarding world not just for being a Muggle - born but also for being a person of color. She could use her intelligence to fight against this double - edged prejudice and work towards changing the views of the wizarding society. Another idea is that Hermione discovers a part of her family's non - white magical heritage that has been hidden. This could lead to a journey of self - discovery as she explores this new aspect of her identity while still dealing with the challenges of Hogwarts life.
One idea could be Hermione using her magical knowledge in the world of a hitwoman. For example, she could use spells to enhance her stealth or disarm opponents in a non - magical way that would seem like the skills of a hitwoman. Another plot could involve Hermione having to take on the role of a hitwoman to protect the wizarding world from a dark force that is using the muggle underworld to its advantage. She would have to adapt to the hitwoman's code while still maintaining her own moral compass from the wizarding world.
One idea could be that in a world where werewolves are more accepted, Hermione discovers Minerva was once bitten and becomes determined to help her during the full moon. She could research new spells to ease the transformation pain.
One idea could be that during detention, Hermione discovers a hidden magical artifact in the classroom. This leads to an adventure where she has to figure out its purpose and keep it safe from those who might misuse it.
They could start a magical school of their own. As a married couple, they would pool their resources and knowledge. Hermione's love for learning and Harry's practical experience would make for a great curriculum. They would face opposition from the traditional wizarding schools at first, but eventually prove that their new way of teaching magic is beneficial for young wizards and witches.
One idea could be that Hermione is switched with a pure - blood witch from a dark family. She then has to navigate the different values and expectations of this new family while still holding onto her own intelligence and thirst for knowledge. For example, she might be expected to participate in dark magic studies, but she uses her wits to find a way around it and secretly study light magic instead.
