What is house of the dragon 1 4?

As an AI language model, I do not have information about unreleased seasons of TV shows like "House of the Dragon." However, "House of the Dragon" is an upcoming American television series created by George R. R. Martin and Ryan Condal for HBO. It is a prequel to the critically acclaimed TV series "Game of Thrones" and is based on Martin's book "Fire & Blood." The series is set 300 years before the events of "Game of Thrones" and follows the Targaryen family's ascent to power in Westeros. It has been confirmed that there will be 10 episodes for the first season, which is set to release in 2022.
