It’s been four months since the kinda disappointing Game of Thrones finale, but HBO is trying to make it up to us with new shows set in the same universe. Filming on a pilot starring Naomi Watts has already wrapped, and now the network appears close to ordering another.
The as-yet-untitled series would take place 300 years before Thrones and focus on the origins of House Targaryen, that of the Mad King, the Mother of Dragons, and — outdated spoiler alert — Jon Snow himself.
The concept for the show was created by writer and producer Ryan Condal and George RR Martin. It’s based on Fire Blood, a series Martin created as a spin-off to the A Song of Ice and Fire and reportedly represents a new take on one of the five prequel scripts HBO commissioned in 2017.
The tagline of Fire Blood is “when dragons ruled Westeros,” which means instead of Daenerys’s three miracle dragons the spin-off should feature way more winged beasts and, we can only presume, a healthy dose of aerial combat.
To date, only the first volume of Martin’s series has been published, which makes us wonder if Martin could be in another situation where a TV series of his lurches ahead of the books it’s ostensibly based on.
Three hundred years is a long time in anyone’s family history, so don’t be surprised if there’s some complicated family tree math to be done connecting the characters in this show to those we meet in Game of Thrones, drawings not unlike those you’d find in the front of one of Martin’s books or on your mail-in DNA test results page.
