Another possibility is that she could be a foreign princess who came to the North for some diplomatic reason. Brandon might have been chosen to host her, and over time, they developed feelings for each other. This would add an interesting dynamic as their son would have a connection to a foreign land.
There's also the chance that it was a commoner. Brandon, being a Stark, might have seen the strength and kindness in a simple village girl. Their relationship could be a secret at first, and when she gives birth to their son, it causes a stir in the North as the Starks are expected to marry within a certain social class.
It could be a northern girl, someone who Brandon met during his travels in the North. Maybe she was a daughter of a minor lord, and they fell in love while he was on a mission to secure the North's borders.
Well, in fanfiction, the story could be about how Brandon Stark's son grows up in a post - Game of Thrones world. Maybe he has to deal with the remaining political unrest. He could be trained in the ways of the North, learning how to be a strong leader like his father.
Brandon Stark is a very important character. He has the power of the Three - Eyed Raven. He starts as a young boy full of curiosity. After many hardships like the fall of his family, he goes on a journey of self - discovery and power - gaining. He witnesses a lot of the dark secrets and power plays in Westeros through his visions.
In the 'Game of Thrones' series, there is no clear indication of a romantic love story between Brandon Stark and Meera. Their relationship is more of a comradeship. Meera helps Bran on his journey, protecting him and being his companion as he discovers his powers and his role in the larger events of the story.
In the normal 'Harry Potter' and 'Game of Thrones' universes, there is no such connection. But in some wild and creative fanfiction, it could be possible. Fanfiction often bends and twists existing universes to create unique and unexpected relationships. However, this is not part of the official lore of either series.
It could be about an original character who is the son of Brandon Stark and has some sort of visionary abilities. Maybe it explores his role in the world of Westeros, his relationships with other characters, and how his unique heritage and abilities shape his destiny.
One significant event was when he discovered his ability to have visions, which was a major step in his transformation into the Three - Eyed Raven.
There could be some characters from outside the North as well. For example, a wandering knight who is impressed by Harry's courage and Stark - like qualities. Or perhaps a foreign noble who has heard of the Starks' reputation and sees Harry as a means to gain influence in the Westeros. These unexpected allies could bring new perspectives and resources to Harry's cause.
Well, often there's the theme of identity. As an original character who is the son of Brandon Stark, he has to figure out his place in the world. There could also be themes related to honor, like how he upholds the Stark honor in difficult situations. Maybe he has to deal with the dark side of the political games in Westeros while still staying true to his family's code. And sometimes, themes of love and friendship also play a part, like how he forms relationships with other characters in the story.
Another fanfiction could be about Jon Snow (who is later revealed to be Ned Stark's son). In this story, he could fully embrace his Targaryen heritage much earlier. He might form an alliance with Daenerys not as an equal but as a leader, using his knowledge of the North and the loyalty of the Night's Watch to help her claim the Iron Throne in a more peaceful way.
I'm not sure about specific 'oc son of brandon stark fanfiction' off the top of my head. However, if you join some Game of Thrones or Stark - related fan communities on social media platforms like Reddit or Discord, you can ask the members there. They are often very knowledgeable and can point you to some really good fanfictions in this area. They might even have written some themselves.
