Superheroes may be on thin ice at Warner Bros Discovery, but they are all in for dragons.

HBO renewed the Game of Thrones sequel House of the Dragon for a second season Friday morning. The move came after Sunday’s premiere episode scored 10 million viewers on its first night, a record season opener for HBO, and around what the network scored for the GoT season 6 debut.

Viewership for the first Dragon airing climbed to 20 million throughout the week across all platforms.

“We are beyond proud of what the entire House of the Dragon team has accomplished with season one,” says Francesca Orsi, executive vp, HBO programming said in a statement. “Our phenomenal cast and crew undertook a massive challenge and exceeded all expectations, delivering a show that has already established itself as must-see-TV. A huge thank you to [co-creator and executive producer George R.R. Martin and co-creator and showrunners Ryan Condal and Miguel Sapochnik] for leading us on this journey. We couldn’t be more excited to continue bringing to life the epic saga of House Targaryen with season two.”

This is good news for all the other planned projects from the same universe. HBO has at least seven Game of Thrones spinoff projects in development (four scripted, at least three animated). Now that Dragon has opened with good numbers and received a second-season renewal, that means at least one other project could get a series order.

Don’t expect the next season to start any time soon, though. The first season of Dragon required 10 months of filming, and on top of that a massive amount of postproduction visual effects work, which began in January and is still ongoing. A 2024 return is most likely as it will be difficult for the production to film and VFX another season by the end of 2023.

The series stars Paddy Considine (Peaky Blinders) as King Viserys Targaryen, Olivia Cooke (Ready Player One) as Alicent Hightower, Emma D’Arcy (Wanderlust) as Princess Rhaenyra Targaryen and Matt Smith (Doctor Who) as Prince Daemon Targaryen.
