Nairn's character, who can only say his name in the popular series, however, assured fans that they will return in the next seasons, said the Hollywood Reporter.
"We have a season off and we have a year's hiatus, solely because I imagine our storyline is up to the end of the books," Nairn said in an interview with Australia's The ABC.
Fans of George RR Martin's epic fantasy series saw Bran, one of the youngest of the Ned Stark's children, meet the three-eyed-raven and the Children of the Forest. These characters are set to become important in the plotline eventually.
