Following the success of "", a prequel of the medieval series may also head to HBO. According to author George R.R. Martin, he has come up with an idea to develop a new show based on his "Dunk and Egg" novellas, which are also set in the world of Westeros, but a hundred years earlier than the events in his "A Song of Ice and Fire" series.
"I have been writing for a number of years a series of novellas set in the same world, the world of Westeros, but a hundred years earlier, about two characters called 'Dunk and Egg'," he says when asked by IGN about the other projects he's developing for HBO. "I published three of those novellas, 'The Hedge Knight', 'The Sworn Sword' and 'The Mystery Knight', and I have in mind about nine or 10 more novellas about the adventures of 'Dunk and Egg'."
