Martin plans to continue writing more novellas about these characters, but so far, the Tales of Dunk and Egg consist of three novellas: 1998's The Hedge Knight, 2003's The Sworn Sword, and 2010's The Mystery Knight. But, if picked up, it would join the other prequel series now in production at HBO, "House of the Dragon", which covers the bloody Dance of the Dragons civil war that occurred about 170 years prior to the start of GoT. Dunk would later go on to become the Lord Commander of the Kingsguard and Egg, the king of Seven Kingdoms, Aegon the Unlikely.
While we've yet to get any of the promised Game of Thrones spinoffs, HBO is now apparently getting to work on another one.
Variety has learned that the series is still in early development at the TV network, with no creators or talent now attached to the project.
Fans have been asking for this project to come to fruition since it was announced that HBO would be making new Game of Thrones adjacent shows.
This latest development was anticipated by some and a surprise for many others, especially given how Martin stated "we're not doing Dunk & Egg" back in 2017 during HBO's initial announcement that several Game of Thrones prequel series' were on the cards.
Martin's three novellas in the "Tales of Dunk and Egg" have been published over the past 23 years. George R.R. Martin and Ryan Condal (Colony) co-created the series, while Miguel Sapochnik and Condal will serve as showrunners.
British actor Paddy Considine was cast in October 2020 in the role of King Viserys Targaryen.
That said, with Disney+ preparing to launch dozens of shows based on properties like Star Wars and Marvel, HBO's got to be feeling the pressure. Another Game of Thrones prequel, which received a pilot episode order with Naomi Watts, was passed-on by HBO in October a year ago.
