House Of The Dragon Season 2 Cast Guide: Every New & Returning Character

House Of The Dragon Season 2 Cast Guide: Every New & Returning Character


  • Season 1 of House of the Dragon sets the stage for the Dance of the Dragons civil war within House Targaryen.
  • The House of the Dragon cast retains many of its characters from the late episodes of Season 1.
  • House of the Dragon season 2 will delve into the action-packed conflicts of the Dance of the Dragons with familiar and new cast members.

Warning! SPOILERS ahead for House of the Dragon Season 1 and minor spoilers for Season 2.The House of the Dragon cast is composed of talented actors who bring to life the intense family dynamics at the height of the Targaryen dynasty. House of the Dragon serves as the first of many upcoming Game of Thrones spinoffs. While House Stark primarily took the lead in Game of Thrones, the prequel focuses on the height of House Targaryen’s power. Season 1 sowed the seeds of the catastrophic civil war known as the Dance of the Dragons, which has divided House Targaryen leading into season 2.

Based on the “fake history” book Fire & Blood by George R.R. Martin, House of the Dragon includes the ancestors of familiar Game of Thrones families like the Starks, Baratheons, Tullys, and Lannisters, deciding which Targaryen claim they support during the civil war. However, some of House of the Dragon’s most major families weren’t featured in the Game of Thrones story, with House Hightower and House Velaryon seeing the heights of their powers during the prequel series’ timeline. There are also more Targaryens and dragons than ever during House of the Dragon, making the family’s conflict all the more devastating.

During House of the Dragon season 1, King Viserys I Targaryen’s succession became a complex dilemma, putting to the test whether the realm would rather see bloodshed than a woman on the Iron Throne. Now, House of the Dragon season 2, set to be released on June 16, 2024, will delve into the action-packed Dance of the Dragons conflict, with major battles, dragon fights, and more on the way. Much of the main cast return for season 2, with some exciting new additions.
