A more complex plot idea would be a love triangle situation where a new character, perhaps a noble from a Westerosi house, becomes interested in Irri. Rakharo then has to deal with his jealousy and also prove to Irri that he is the better choice. This could bring out different aspects of the Dothraki culture regarding courtship and loyalty, and also show how Irri navigates through this unexpected situation.
One interesting plot idea could be Irri teaching Rakharo about the ways of the Dothraki that he might not be familiar with, despite being a Dothraki himself. Maybe she shows him a more spiritual side of their culture that he had overlooked in his focus on being a warrior.
Their relationship could develop through shared experiences. For example, if they go on a dangerous journey together, like through the Red Waste. During this journey, they rely on each other for survival, which deepens their bond.
One common theme is loyalty. Rakharo is often depicted as being extremely loyal to his khalasar and those he respects. Another theme is survival in the harsh world of Westeros.
One idea could be exploring what would happen if a minor character like Gendry had been secretly trained in magic. He could use his newfound powers to unite the smallfolk against the warring nobles. Another plot could revolve around a female knight from the North who disguises herself as a man to fight in the wars, and along the way, she discovers secrets about the White Walkers that no one else knows. Or perhaps a fanfiction where Daenerys and Sansa form an alliance much earlier and together they reshape the power dynamics of Westeros.
A really cool 'Game of Thrones fanfiction' plot could involve the resurrection of some of the dead characters in a different way. For example, what if Ned Stark was brought back not as a vengeful wraith but as a wise advisor to a new king or queen? His honor and wisdom could shape the future of Westeros in a completely new direction. And it would be interesting to see how the other characters react to his return.
Perhaps a fanfiction where Daenerys Targaryen lands in Westeros earlier and forms an alliance with the Starks before the events of the main series. This would completely shift the political landscape and the fight for the Iron Throne. She could bring her dragons to help fight the White Walkers from the start.
One idea could be exploring what would happen if a minor character, like Gendry, had a more central role in the fight against the White Walkers. He could lead a group of common folk and prove that the power doesn't always lie with the nobles.
One great 'Game of Thrones Rakharo fanfiction' is 'Rakharo's Journey'. It delves into his adventures beyond what we see in the show. Another is 'Rakharo and the Lost Tribe' which creates an interesting backstory for him.
One interesting plot idea could be the return of a long - thought - dead character with a new mission. For example, if Ned Stark somehow came back and had to navigate the even more complex political landscape of Westeros. Another could be the exploration of the relationship between Daenerys and Jon Snow in a more in - depth way, perhaps with some new challenges that test their alliance.
Another plot could involve a goddess who was once worshipped in ancient Westeros but forgotten over time. She resurfaces during the chaos of the Game of Thrones. This goddess has the power to manipulate the elements and she decides to test the worthiness of the claimants to the Iron Throne by sending various trials their way.
Perhaps a plot where the gamer character discovers a hidden aspect of the magic in the Game of Thrones world through their unique 'gamer' perspective. This could lead to new powers being unlocked and changing the power dynamics among the different houses.
