Do people still care about Game of Thrones? If the House of the Dragon panel at San Diego Comic-Con was any indication, the answer is a roaring yes. Fans crammed into the spacious Hall H to get the latest updates on the first official spinoff of HBO’s hit fantasy show. Here’s what we learned.

The cast of House of the Dragon cast was joined on stage by executive producer Ryan Condal and George R.R. Martin, who wrote the books that inspired the entire franchise. Martin, who’s been isolating for years while working slowly on his next book in the series, told the crowd he’s seen nine out of 10 episodes and approves.

“Ryan has done a great job of adapting the book so far,” Martin said. “Our cast here is amazing. I’m very happy.”

When the topic of Winds of Winter came up, Martin admitted that he’s still working on the long-delayed book and made a surprising promise.

“I don’t see visiting the set or doing anything until I deliver that book,” the author said. “And then if the show’s still going, I’ll show up.”

If that happens, it wouldn’t be the first time he did a cameo for HBO.

“I did do a cameo of the original Game of Thrones pilot but they reshot it,” he revealed.

Dragons!

On the topic of dragons, Condal went into detail on how they worked hard to make each CGI monster stand out.

“There are 17 dragons at the height of this,” he said. “So it was important to differentiate them in how they look and behave. That was one of the earliest things we started concerting on a year before we started filming. Worked with conceptual designers. And of course George gave us the gift of specifying color and size and age. We took all that and tried to extrapolate. Caraxes is very cantankerous, always moving and flexing and never sits still. Vhaga is the biggest dragon alive right now.”

“We’ve designed dragons you won’t even see in Season 1,” Candor added. “There’s much moe to come.”

Milly Alcock, who plays Princess Rhaenyra Targaryen, revealed that the filmed the dragon-riding scenes using the Volume, the LED backdrop technology used on The Mandalorian and Thor: Love and Thunder.

“We worked on a volume stage,” she said.

What’s the House of the Dragon plot?

Based on the Fire and Blood books by George R.R. Martin, House of the Dragon recounts the political infighting among House Targaryen 200 years before Game of Thrones begins. Already ruling Westeros, the series marks the beginning of the end for the powerful dragon-riding clan leading up to a Targaryen vs. Targaryen conflict known as the Dance of Dragons. On that note, you can also expect a lot more dragons here than we got in GoT, where the beasts were rare and believed to be a myth by many.
