Two of the potential 'Game of Thrones' prequels are about the Targaryens

George RR Martin may not be writing any of the Game of Thrones prequel series, but he certainly has insider knowledge about the stories they'll tell.

And he just spilled the beans on two of them.

While Martin had hinted on his blog that one of the not-yet-greenlit series has something to do with the Targaryens, he revealed in an interview with The Guardian that "at least two of them are solidly based on material in Fire and Blood. Those haven’t been greenlit yet."

Fire and Blood is a canon history of the Targaryen conquest, which is what happened when Daenerys and Jon's great-great-super-great grandparents rained, well...fire and blood on the continent of Westeros.

In the conquest, Aegon the Conquerer (who Jon Snow is named after) and his two sister-wives took over the seven kingdoms and unified them under House Targaryen by convincing their leaders to bend the knee — something their Thrones-era descendants seem to have a knack for as well.

Martin mentioned that the other prequels are "all over the map," which could mean stories taking place across the Narrow Sea and beyond.

The interview also touched on Martin's progress with writing The Winds of Winter, the long-awaited next book in A Song of Ice and Fire. Martin described Winds as "a dozen novels" and stressed that its complexity was part of the reason its release is delayed.

As for what comes after The Winds of Winter, Martin said that he's not sure if he'll go straight into writing the final book in the series.

"The Winds of Winter is next, then I’ll decide what comes after that – whether it’s to go on to A Dream of Spring, the last one, or whether I switch back into Fire and Blood II, do another Dunk and Egg story or two. But I’ll worry about that one thing at a time – that’s too far ahead.”

And so the wait continues for The Winds of Winter and the final season of Game of Thrones, but at least there's new prequel news to be excited about.
