Maybe Hermione tries to educate the people of Westeros about things like hygiene and basic science using her vast knowledge, and Harry uses his courage and dueling skills to face the threats in this new world.
One possible plot could be that Harry and Hermione somehow end up in Westeros through a magical portal.

For example, they could help a certain house in the Game of Thrones - like scenario, using spells to protect their allies or uncover the secrets of their enemies.
In this fanfic, perhaps they arrive in Westeros during a time of great chaos, like when the White Walkers are approaching. Harry and Hermione could bring a new element of magic that the people of Westeros have never seen. They might join forces with some of the key characters, like Jon Snow or Daenerys Targaryen. Harry could teach the people how to better defend against the undead with his Patronus charm, and Hermione could use her intelligence to figure out the weaknesses of the White Walkers.
The White Walkers could be major antagonists. They are a huge threat in Westeros and Harry and Hermione would have to use their unique magical abilities to combat them. Their cold - based magic and army of the undead would be a great challenge for Harry and Hermione.

In a 'Harry Potter Lord in Westeros' fanfiction, the plot could center around Harry Potter becoming a lord in Westeros through some magical means. As a lord, he would have to deal with the typical issues like managing his lands, protecting his people, and forming alliances. However, his magic would give him an edge. He could use spells to improve the harvests, defend his castle from invaders more effectively, and even try to bridge the gap between the different houses by using his unique perspective from the wizarding world.
One possible plot could be that Harry Potter, through some magical accident or powerful spell, is transported to Westeros. He might use his magical abilities to quickly rise in power, perhaps by impressing the local lords with his feats of magic. He could then set out to unite the kingdoms under his rule, using a combination of wizardry and political savvy that he learned from his time at Hogwarts and in the wizarding world.
In a fem Harry prank in a Westeros fanfic, a lot could occur. Maybe fem Harry uses her magic in unexpected ways to play pranks on the Westerosi nobles. For example, she could make their elaborate wigs fly off during a formal gathering, causing chaos and hilarity. It would be a great way to add some humor to the often - serious Westeros setting.
Well, perhaps it could be a fanfic where they are on a secret mission together. After getting dirty during the mission, they find a single shower area in an old, abandoned building.

Harry might be the first to notice something odd, Hermione would try to analyze it, and Draco would be reluctantly involved.
In a 'Harry and Hermione run away fanfic', they could be running away from the pressure of their pre - destined roles. Harry is always seen as the 'Chosen One' and Hermione as the brilliant sidekick. Fed up with these expectations, they decide to run away and explore the wizarding world on their own terms. They might travel to different wizarding schools across the globe, learning new spells and making new friends outside of Hogwarts.
Perhaps the toy is a little magical animal figurine that can move and talk, and it's designed to keep Hermione company during her long hours in the library. Harry might have made it as a way to make her smile during her stressful study times. He could have spent a lot of time researching spells and materials to create something truly special for her.
Well, perhaps the ritual is related to enhancing their magical abilities. Harry might be providing moral support and practical help like gathering rare ingredients for Hermione. Maybe they need to perform the ritual to protect Hogwarts from a new dark threat.
