There's 'Jaime's New Path' which is really interesting. This fan fic focuses on an alternate universe where Jaime makes different choices early on. He teams up with characters he normally wouldn't, and it completely changes the trajectory of his story, exploring his relationships in a fresh way.
You could also follow blogs or social media accounts that are focused on 'Game of Thrones' fan fiction. Some bloggers are really into Jaime Lannister's character and regularly feature and review the best fan fictions related to him.
He could marry a foreign princess. This would bring a new dynamic as she might have different cultural values and beliefs, which would create interesting storylines as Jaime adjusts to being with her.
I really liked 'Jaime Lannister: A Different Path'. In this fanfiction, Jaime decides to side with the Starks early on. It's an interesting take as it completely changes the course of his character in a believable way. There are some great character interactions that are not in the original show.
One great 'Jaime Lannister OC Wife Fanfiction' is 'The Lion's Bride'. It delves deep into the relationship between Jaime and his original character wife. The story shows how she changes his perspective on life and honor in the complex world of Westeros.
A popular 'Jaime Lannister x Reader Fanfiction' is 'Bound to a Lannister'. It's unique in that it starts with an unexpected encounter between the reader and Jaime. The story then unfolds to show how their relationship blossoms in the midst of all the chaos in Westeros. 'Jaime's Secret Affair' is another interesting one. It plays on the secrecy and danger of their relationship, which adds an extra layer of excitement. The author does a great job of building up the sexual tension, without it being too over - the - top.
Redemption is also a theme in some fan fictions. Given their often - immoral actions in the original story, some fan fictions explore the idea of Jaime and Cersei seeking redemption, either together or separately, and how this affects their relationship and their place in the world of Westeros.
A great one might be 'Jaime's Magical Redemption'. In this, Jaime gets magic that helps him atone for his past sins. He uses his magic to help the common people, which is a big change from his previous self - centered actions. It's a story that really delves into his character development with the added element of magic.
Sure, many fanfiction authors like to play around with different character combinations and scenarios. Jaime Lannister is a complex character, and Lyanna has her own allure in the story. The idea of her being pregnant in a fanfiction involving Jaime could be used to explore themes like love, honor, and the consequences of actions. It might show how these two characters from different houses and storylines interact in such a situation.
There's also an OC that was a priestess. She had a very different world view from Jaime, and their interactions were really interesting as they debated about morality and faith. The author did a great job in making her character complex and multi - faceted.
I also like 'Cersei and Jaime: A Different Path'. This fan fiction explores an alternate universe where Jaime and Cersei make different choices early on in their lives. It shows how those choices could have changed their relationship and the entire course of events in Westeros.
