‘House of the Dragon’ Official Trailer Brings ‘Games of Thrones’ Violence and War Back to HBO

HBO has released the first official trailer for “House of the Dragon,” the network’s “Game of Thrones” prequel series debuting on Aug. 21.

The show, set 200 years before the events of “Game of Thrones,” follows the tumultuous story of House Targaryen under the rule of King Viserys I.

“House of the Dragon” will follow the Dance of the Dragons, the Targaryen civil war between siblings Aegon II and Rhaenyra, who fought for the throne after the death of their father.

The war pits Westeros’ great houses — including the Lannisters and Starks — against each other, resulting in the death of House Targaryen’s most powerful dragons.

It would take centuries until Westeros would see another dragon, all thanks to Daenerys Targaryen (Khaleesi).

While there are other Westeros-related series in development, “House of the Dragon” is the only confirmed “Game of Thrones” spinoff show — so far.

House of the Dragon comes from co-creators and showrunners Ryan Condal (Colony) and Miguel Sapochnik (Finch) and is based on Martin’s book Fire & Blood.
