Another plot could be that they meet during a time of great plague in Westeros. They initially suspect each other of being the cause but then realize they need to work together to find a cure. They travel across the land, facing dangerous groups and old enemies. Along the way, they learn about each other's pasts and form a deep bond.
Their relationship could start off rocky. Yara is a fierce and independent Ironborn, while Ellaria is from Dorne and has her own set of values. But as they face common enemies, like the Lannisters, they start to respect each other's skills. For example, Yara might admire Ellaria's ability to manipulate political situations in Dorne, and Ellaria could respect Yara's leadership on the seas.
One interesting fanfiction could be about Yara leading the Ironborn in a new conquest. Maybe she discovers a hidden island full of treasures and has to battle both external enemies and deal with internal power struggles among her own people.
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.
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.
Perhaps a Futa warrior from beyond the Wall who comes to the Seven Kingdoms. This character could bring new fighting techniques and a different perspective on the war for the North, and interact with well - known characters like Jon Snow in unexpected ways. They might even have knowledge of the White Walkers that could change the course of the story.
One idea could be a story where the survivors of the Fallout world discover ancient Valyrian steel weapons and try to figure out how to use them. Maybe they think the weapons have some sort of magical power that could help them in their post - apocalyptic struggles.
