HBO doesn’t currently have plans for a Game of Thrones spinoff show, but series author George R.R. Martin has some suggestions for them anyway.
“There is certainly no lack of material,” Martin told Entertainment Weekly about a potential spinoff. “[There’s] a whole world full of stories, waiting to be told… if indeed HBO is interested.”
Martin then said specifically what he think would make most sense as a television continuation of stories from Westeros: his Dunk & Egg stories. EW reports that these tales take place about 90 years prior to the current series, and follow a hedge knight, Ser Duncan the Tall, and his squire Egg.
“The Hedge Knight and its sequels are lighter [in tone] than A Song of Ice and Fire, more in the realm of action/adventure,” Martin said.
