'House of the Dragon' Officially Takes Its Biggest Risk With a Major 'Fire & Blood' Book Change

House of the Dragon is charting a new course in its third season. While George R.R. Martin’s Fire & Blood serves as the foundation for the series, the latest episodes show a clear intent to move away from the established source material. This shift is most evident in the storyline surrounding Corlys Velaryon.

The sixth episode of the current season features a major departure from the book. In the original text, Corlys remains in King's Landing to serve as an advisor during the war. However, the show opted for a different approach. The episode concludes with a cliffhanger that sees the Sea Snake captured by the forces of Ormund Hightower. This plot point does not exist in the novel and places the character in a position of immediate danger.

This creative choice shifts the focus toward other members of the Velaryon family. With Corlys missing, Alyn of Hull and Baela Targaryen are now positioned to take on larger roles. Alyn has already begun to navigate the complex politics of the small council, and the show appears to be setting up a partnership between him and Baela as they search for the missing lord. Their combined actions are expected to define the next phase of the narrative.

The willingness to deviate from the source material remains a point of interest for long-time fans. While the series continues to adapt the general arc of the Dance of the Dragons, these specific changes allow for new character dynamics. The absence of Corlys creates a vacuum that challenges the next generation, forcing them to step out of his shadow and into the conflict in ways that were not present in the book. It remains to be seen how these changes affect the ultimate outcome of the war, but for now, the path forward for the Velaryons is uncharted.
