In a 'Harry Potter marries Rhaenys Targaryen' fanfiction, the plot might be centered around a new threat that can only be defeated by the combined powers of the wizarding world and the Targaryen magic. Harry and Rhaenys are brought together by fate or some powerful magic. As they meet, they are both fascinated by the other's world. Harry shows Rhaenys the wonders of Hogwarts and magic wands, while Rhaenys introduces Harry to dragons and Valyrian steel. Their relationship blossoms into love, and they decide to marry. However, there are political intrigues in Rhaenys' world and dark forces in Harry's world that try to prevent their union.

The plot could center around a love story that overcomes many obstacles. They come from different regions with different traditions. Rhaenys might face challenges in adapting to the cold and harsh North, while Robb might have to deal with the expectations of his bannermen regarding this foreign bride. However, their love could grow as they learn about each other's strengths and weaknesses. They could start to see the similarities between their two families in terms of loyalty to their own, and this mutual understanding could form the basis of a strong relationship.

Among the common people, it could be a cause for celebration in some areas. If the fanfiction portrays their marriage as a union for peace and prosperity, the people might welcome it. They would hope that the combined strength of the Starks and the Targaryens would mean better protection from threats such as bandits and invaders. Among the nobles, there would be a lot of political maneuvering. Some might try to use their marriage to their own advantage, while others might fear that they would be left out of the new power structure that would surely form as a result of this union. For example, smaller houses might try to ally themselves quickly with the couple to gain favor.
Perhaps the plot could involve the two coming together to fight a common enemy.

They would then have to navigate the power struggles in Westeros, with many houses vying for control.

In the 'Harry Potter marries Blackfire' fanfiction, it could start with Harry being sent on a diplomatic mission to Blackfire's homeland.

As they work together on some magical problem or task in her land, their relationship grows. Their marriage could then be a symbol of unity between the Hogwarts - associated wizarding world and Blackfire's people.
