  The episode was written by series co-creators David Benioff and D. B. Weiss.
  This episode was written by David Benioff and D. B. Weiss, the series' creators. It contains content from George Martin's novels ''A Feast for Crows'', chapters Cersei X and Cat of the Canals and ''A Dance with Dragons'', chapter The Ugly Little Girl.
  Like other episodes this season, "Hardhome" contained a large amount of original material that does not appear in Martin's novels. This includes the battle scene in which the Wildlings and Night's Watch are ambushed by the White Walkers and army of the undead, as well as the meeting of Daenerys Targaryen and Tyrion Lannister. According to Erik Kain of ''Forbes,'' "We have now fully parted ways with the books. If the rest of Season 5 hadn't convinced you that the show was forging its own path, this episode is the final nail in the coffin."
