By the time Game of Thrones wrapped up its record-breaking eight-season run in 2019, it was a no-brainer that HBO would be producing another GoT series to keep the success going. The first announced show in the works, which was reportedly picked from a few prequel ideas, was going to chronicle a time thousands of years before the start of GoT, and was set to star actress Naomi Watts. Unfortunately, that project was eventually scrapped after the pilot was shot—but a new prequel series, House of the Dragon, was announced in October 2019. Here's what we know about it so far.

1. House of the Dragon will be based on George R.R. Martin's book Fire & Blood.

George R.R. Martin's novel Fire & Blood, which tells the story of House Targaryen, will serve as the source of inspiration for the plot of House of the Dragon. The first of two volumes was published in 2018, and takes place 300 years before Game of Thrones.

2. House of the Dragon will likely chronicle the Targaryen family's tumultuous past.

Game of Thrones showed that the Targaryen family has a long-standing history of inbreeding, secrets, betrayal, war, and insanity. Fire & Blood covers topics like the first Aegon Targaryen's conquest of the Seven Kingdoms and his subsequent reign, as well as the lives of his sons. Seems like we'll probably be meeting Dany's ancestors, and Martin confirmed there will definitely be dragons present—maybe even Balerion the Black Dread, the biggest dragon in all of Westerosi history.

Martin shared on his blog that he's been working with writer and producer Ryan Condal (Rampage, Colony), on the show. "Ryan Condal is new to Westeros, but not to me," the acclaimed author wrote. "I first met Ryan when he came to New Mexico to shoot a pilot for a fantasy western that was not picked up. I visited his set and we became friendly ... He’s a terrific writer … and a fan of my books since well before we met." In another blog post, Martin said that the show's script and bible were "terrific, first-rate, exciting." Sounds like we'll be in good hands.

5. A Game of Thrones director is returning for House of the Dragon.

Per a tweet from the Game of Thrones Twitter account announcing the show, Miguel Sapochnik, who directed many of the original HBO series' biggest episodes, such as "Battle of the Bastards" and "Hardhome," will be returning for House of the Dragon as showrunner alongside Condal. Sapochnik is also known for directing a handful of other notable shows, such as True Detective, Masters of Sex, and Altered Carbon.

6. House of the Dragon could be coming in 2022.

HBO ordered 10 episodes of House of the Dragon, and HBO president of programming Casey Bloys said he thought that the show would debut "sometime in 2022." However, with the film industry facing major delays due to safety concerns surrounding the coronavirus pandemic, there's no word on when the show will begin filming.

Meanwhile, Martin revealed that he won't be writing any scripts for House of the Dragon until he finishes The Winds of Winter, which has been in the works since A Dance With Dragons, his most recent book in the A Song of Ice and Fire series, debuted in 2011. The good news, however, is that Martin says he has been "writing every day" while keeping indoors and social distancing, leaving fans with the hope that The Winds of Winter will come soon.
