In fanfiction, 'Harry Potter changes Westeros' could be through his magic skills.

Well, Harry Potter might change Westeros in fanfiction by influencing the political structure. He comes from a world where there are different forms of governance within the wizarding community. His ideas about fairness and equality could seep into Westeros and make the lords and ladies think differently about how they rule. Also, his ability to face dark forces could inspire the characters in Westeros to be more courageous in their own battles against tyranny.
One way Harry Potter could change Westeros in fanfiction is through his relationships. He's used to forming strong bonds with his friends at Hogwarts. In Westeros, he could form similar friendships that cross the boundaries of the different houses or kingdoms. His loyalty to his friends could set an example. Moreover, his magical education might lead to the founding of a new school or a place where magic is studied in Westeros, which would completely transform the cultural and educational landscape of the continent.
A major impact would be on the economy. In the Harry Potter world, there are unique magical items and potions that could be introduced to Westeros. For instance, the Felix Felicis potion could be used by merchants to have good luck in their business dealings. This would change the way trade is conducted. Also, the introduction of magical beasts like hippogriffs could be used for transportation, which would revolutionize the travel and delivery industry in Westeros.
The fem Harry Potter could also change the power balance. If she aligns herself with a particular house, that house would gain an edge.

This new information would disrupt the existing plans of the different factions vying for the Iron Throne and other power positions.

Harry might see his intelligence, and Kreacher might be a bit wary of his Lannister name.
The knights in Westeros would be both intrigued and a bit intimidated. Harry's magic is something they've never seen before. Some might want to learn from him, while others might see him as a threat to their traditional way of fighting. The maesters would be very interested in studying his magic, trying to figure out how it works and how it could be incorporated into their knowledge. The children in Westeros would probably be in awe of him, especially if he shows off some cool magic tricks. They might start dreaming of becoming wizards themselves, which would be a huge change in their aspirations.
One possible plot could be that Harry Potter, through some magical accident or powerful spell, is transported to Westeros. He might use his magical abilities to quickly rise in power, perhaps by impressing the local lords with his feats of magic. He could then set out to unite the kingdoms under his rule, using a combination of wizardry and political savvy that he learned from his time at Hogwarts and in the wizarding world.
In fanfiction, Harry and Kreacher could be seen exploring the different terrains of Westeros. Maybe they stumble upon the Iron Islands. Kreacher could be fascinated by the Ironborn way of life while Harry tries to find a way to use their naval power for some greater good. Or they could end up in King's Landing and face the political intrigue there.

In a 'Harry Potter Lord in Westeros' fanfiction, the plot could center around Harry Potter becoming a lord in Westeros through some magical means. As a lord, he would have to deal with the typical issues like managing his lands, protecting his people, and forming alliances. However, his magic would give him an edge. He could use spells to improve the harvests, defend his castle from invaders more effectively, and even try to bridge the gap between the different houses by using his unique perspective from the wizarding world.

This can create new sub - plots. For example, if two students from different houses start to collaborate on a project because of a small change in the fanfiction's setup. It would add more depth to the story.
