Fanfiction about Harry Potter and Tywin Lannister: What could be an interesting plot?

Well, perhaps in this fanfiction, Harry Potter could end up in Westeros and meet Tywin Lannister. Harry, with his knowledge of magic, could be seen as a threat or an asset by Tywin. Tywin might try to use Harry's magic for his own military purposes, like using magic to enhance his army's weapons or defenses. Harry, on the other hand, would have to navigate the cut - throat politics of Westeros while trying to keep his magic a secret from those who might misuse it.

One possible plot could be that a spell goes wrong in the Harry Potter universe and he ends up in the world of the Lannisters. He forms an unlikely alliance with some of the Lannisters, like Tyrion, who is more open - minded. Together, they try to change the way the Lannisters operate, using Harry's sense of justice and magic. Harry also has to deal with the prejudices of the people in Westeros towards magic, all while trying to figure out how to return to his own world.

Harry would likely be cautious around Tywin. He's used to dealing with villains, and Tywin's cold and power - hungry demeanor would set off alarm bells. Tywin, in turn, would probably see Harry as an enigma, a boy with strange powers that could be useful or dangerous. He might try to manipulate Harry into doing his bidding.

Well, Harry is brave and selfless, while Tywin is cunning and power - hungry. Harry would be appalled by Tywin's often ruthless and self - serving ways. For example, Tywin might see the use of Unforgivable Curses as just another tool in his political arsenal, while Harry firmly believes in the right and wrong of magic. Their values are so different that it would be like oil and water.

One idea could be a political alliance. Rhaella, being a Targaryen, and Tywin, a powerful Lannister, could form an uneasy alliance to deal with a common threat to the Seven Kingdoms. They might start off distrustful of each other but gradually come to respect one another's political acumen.

One plot idea could be that Tywin, seeing Sansa's value as a political pawn, decides to use her in a different way than originally planned. Instead of marrying her off to Tyrion, he takes her under his wing to teach her the ways of politics in Westeros. This could lead to an unlikely bond between them as Sansa tries to navigate the dangerous world of the Lannisters while still holding onto her Stark identity.

One idea could be the daughter getting involved in the political intrigues of King's Landing. Maybe she has to navigate the complex relationships between the different houses while trying to uphold the Lannister name. Another could be her having a secret talent, like being an excellent strategist, which she uses to help her father in unexpected ways.

One plot idea could be Arya, in disguise, getting close to Tywin as a servant in King's Landing. She could overhear his plans and use that knowledge to try and undermine the Lannisters from within. Another could be a scenario where Tywin discovers Arya's true identity but decides to keep her alive for some strategic reason, perhaps to use her as a bargaining chip against the Starks. And a third idea might be a story set in an alternate universe where Arya and Tywin form an unlikely alliance against a common, greater threat, like a White Walker invasion in the south before the events at the Wall.

One idea could be the OC's struggle to live up to his father's reputation. He might face challenges within the Lannister family, like dealing with his siblings' envy or rivalry. Another could be his role in the political games of Westeros, perhaps trying to form alliances different from his father's.

The novelty of original characters. They can bring new perspectives to the world of Tywin Lannister. For example, an OC could be from a different social class and show us how Tywin interacts with those he normally wouldn't deal with.
