Introducing Endless Mode: A New Games & Anime Site from Paste
In early May, we reported that HBO was developing four separate Game Of Thrones prequels, with the plan being to take the best one and turn it into a proper new TV series. Shortly after that, George R.R. Martin that there was a fifth potential prequel in the works, and while the others all had writers attached, Martin would only say that the fifth one was being worked on by a “great guy and a fine writer” who knows more about Westeros than pretty much anyone else. Now, thanks to Entertainment Weekly, we know that this mysterious fifth writer is Game Of Thrones co-executive producer Bryan Cogman, a former assistant to showrunners David Benioff and D.B. Weiss who has been with the show since the first season.’
