Some fanfictions might explore a love story between Hermione and Aragorn. Given their different backgrounds, it could be a slow - burn relationship. Maybe Aragorn is initially suspicious of Hermione's magic but as they spend more time together, he comes to respect and love her. And Hermione, in turn, is drawn to Aragorn's leadership and noble character. They could also face opposition from both their worlds, which adds more drama to the story.
A really interesting plot could be a time - travel scenario. Aragorn travels to the future and ends up in the wizarding world where he meets Hermione. She teaches him about modern magic and they go back to Middle - earth together to use this new knowledge against an ancient evil. Or perhaps there's a prophecy that involves both of them, and they must figure out their roles in fulfilling it, which takes them on a journey across both their worlds, facing various challenges along the way.
One idea could be that the OC is a healer who joins Aragorn's journey. They meet during a battle where Aragorn is injured and the OC uses their unique healing skills to save him. This starts a bond between them as they travel together, with the OC providing medical aid to the whole fellowship.
One idea could be focusing on the preparations for the baby. Aragorn, as a king - to - be, would have to ensure the safety and future of his heir. He might strengthen alliances and fortify the kingdom. Arwen, on the other hand, could be shown interacting with the elven community, sharing the news and getting advice from the elder elves. Another plot could revolve around the cultural differences between Aragorn's human side and Arwen's elven side in terms of raising a child. For example, elves have a long lifespan and different values compared to humans.
A really interesting twist could be that Hermione's presence in Middle - earth is actually a key part of an ancient prophecy that no one knew about. As Aragorn's sister, she might be the one to unlock some great power or knowledge that is crucial for the victory over evil. This would make her a central figure in the story, not just as Aragorn's sister but as a key player in the fate of Middle - earth.
Another plot could be that Hermione, being the brilliant witch she is, gets sorted into Hufflepuff by mistake (or maybe it's not a mistake). She initially struggles with the idea as she has always identified more with Gryffindor. But as she spends time in Hufflepuff, she realizes that the house values are just as important and noble. She then uses her intelligence to help Hufflepuff gain more recognition in the wizarding community.
One idea could be that Hermione discovers she has a special connection to the gorgon world. Maybe she can understand their language and has to use this ability to prevent a war between the gorgons and the wizarding world. Another plot could involve Hermione being turned into a gorgon - like creature temporarily and having to learn to control her new powers while facing prejudice from some of her classmates.
A possible plot could be that Hermione gets bitten by Greyback accidentally. Instead of turning into a full - blown werewolf, she has some new abilities and a strange connection to Greyback. They then have to figure out how to deal with this new situation, while also facing the wizarding world's prejudice against werewolves. It could also involve Hermione using her intelligence to find a cure for herself and in the process, changing Greyback's view of non - werewolves.
A possible plot is that Hermione, while researching for a new spell theory, stumbles upon a long - forgotten charm that was created by Rodolphus. This draws her attention to him, and she decides to find out more. Meanwhile, Rodolphus, who has been in hiding, senses someone is looking into his past work. When they meet, there is a clash of personalities. However, as they start to discuss the charm and its potential, they find common ground. Another idea is that in a world where magic is fading, Hermione believes that Rodolphus might have some knowledge that could help. She approaches him despite the risks. He, in turn, sees an opportunity to make amends for his past deeds through helping her. Also, they could be brought together by a prophecy that only they can fulfill, which forces them to put aside their differences and work together.
One interesting plot idea could be that Krum returns to Hogwarts for a Quidditch tournament. Hermione is now a teacher's assistant, and they rekindle their old feelings while discussing the strategies of the game. They face some opposition from students who don't understand their relationship, but they work through it together.
A third plot idea is that Hermione, in a strange magical accident, gets some of Morgana's memories. She then has to deal with these new memories and the emotions that come with them. She might struggle between her own values and the things she sees in Morgana's memories. This could lead to a transformation in Hermione's character as she tries to make sense of it all.
One plot idea could be that Hermione is a powerful elf with ancient magic knowledge. She uses her elven abilities to solve mysteries in Hogwarts that normal humans couldn't. Another could be that she's a magical being from a different dimension, and she has to hide her true form while trying to fit in at Hogwarts. Maybe she's a phoenix in human disguise, and she shows her phoenix powers at crucial moments to save her friends.
