In some fanfictions, Harry Potter might die by dragon in a battle. Maybe he's outnumbered by a group of aggressive dragons and they overpower him. His spells might not be enough to fend them off, and in the end, a dragon's fire or a powerful attack could be his end.
As the story progresses, the rivalry between Rhaenyra and Alicent intensifies. Rhaenyra has a claim to the throne as Viserys' named heir, but Alicent's son also has a claim. This leads to political intrigue, alliances being formed and broken, and battles for power. There are also external threats and internal dissent that shape the development of the plot. Dragons play a crucial role in this power struggle, as they are a symbol of Targaryen power and are used in battles and to assert dominance.
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.
In the 'House of the Dragon' novel, power is explored through the struggle for the Iron Throne. Different characters have different ideas about who should rightfully sit on it, leading to intense rivalries.
The real story of House of Dragon is a prequel to Game of Thrones. It focuses on the Targaryen family, while Game of Thrones had a much broader scope with multiple houses vying for power. In House of Dragon, we see the origins of some of the things that are important in Game of Thrones, like the importance of dragons. Also, the political intrigue in House of Dragon is more centered around the Targaryens, whereas in Game of Thrones it was spread across Westeros among many different players.
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.
