'Game of Thrones' Prequel Series 'Tales of Dunk & Egg' in Development!

Tales of Dunk and Egg is in the works at HBO, which is great news for Game of Thrones fans as it is a prequel series to the events that happen in the smash hit series!

Here’s what you can expect, direct from Variety: “Based on the series of fantasy novellas by George R. R. Martin, which follow the adventures of Ser Duncan the Tall (Dunk) and a young Aegon V Targaryen (Egg) 90 years prior to the events of ‘A Song of Ice and Fire.’”

The publication noted that the show is in “early development,” but noted it is a “high priority for HBO” to build on Game of Thrones‘ mass appeal.

There is another Game of Thrones prequel series in the works that has just announced a main cast recently, but will not debut this year.
