HBO is nearing a pilot commitment for a prequel series based on the “Game of Thrones” companion book “Fire & Blood,” sources have confirmed to Variety. The book tells stories of previous Targaryen kings, like Aegon the Conqueror, the first ruler of Westeros, and Aegon the Dragonbane, all of whom are ancestors of Daenerys Targaryen (Emilia Clarke) and Jon Snow (Kit Harington) who appear in the recently finished mega-hit series.
The prospective pilot hails from Martin and “Colony” co-creator and executive producer Ryan Condal, and would be set 300 years before the events of the original series, exploring the beginning of the end for House Targaryen.
HBO declined comment. Author George R. R. Martin had previously hinted via his blog that one of the prequel series would be based on the companion book.
The cabler originally announced that five spinoff series were in the works.
