It's highly unlikely that the characters in 'House of the Dragon' would actually watch fanfiction about themselves. Fanfiction exists in our world, created by fans for fans, and the characters in the show are fictional entities within their own fictional universe. They don't have access to the fan - created stories about them.
I'm not sure specifically what the 'harwin strong fanfic' is about as there could be many different interpretations depending on who wrote it. It might be a fan - created story centered around a character named Harwin Strong in a particular fictional universe.
There's also 'Love in the Shadows: Harwin and Rhaenyra'. This one focuses on the more private and tender moments between them. It beautifully describes their love that had to be hidden from the public eye, and how they managed to find solace in each other despite all the difficulties.
Definitely not a true story. House of the Dragon is a work of imagination and creativity. It weaves a complex tale of power, politics, and dragons within a fictional realm.
You could try searching on popular fanfic websites such as Archive of Our Own (AO3) or FanFiction.net. These platforms often have a large collection of fan - created works, and there's a good chance the 'harwin strong fanfic' might be there.
One great Harwin Strong fan fiction could be one that explores his relationship with other characters in-depth. For example, a story might focus on his loyalty to a particular house and how that affects his decisions. It could show his interactions with lords and ladies, and how he maneuvers through the political intrigue of the world.
Power dynamics play a significant role as well. Their relationship can have an impact on the power balance in the kingdom. Fanfictions may depict how they use or are affected by their positions of power in relation to their love, and how they navigate through the political intrigue that surrounds their marriage.
The relationship between Harwin and Rhaenyra is full of intrigue. In fanfiction, it allows us to explore the 'what - ifs'. For example, what if they had more freedom to be together? Fanfictions can expand on their story, filling in the gaps left by the original work.
There's also 'Harwin Strong: The Unsung Hero'. This fanfiction shows his actions behind the scenes that are not always depicted in the original work. It gives a more comprehensive view of his role. It describes his skills in combat and his influence on those around him in a very interesting way.
