Arya continues to travel north to the Wall, and makes the acquaintance of a most unusual character - Jaqen H'ghar- but when the recruits for the Night's Watch are stopped by the Gold Cloaks, a confrontation seems inevitable...

Meanwhile, Catelyn Stark must come to terms with her son, Robb, is now also the King in the North - and that sometimes family and politics conflict.

In May 2017, after years of speculation about possible successor series, HBO commissioned Max Borenstein, Jane Goldman, Brian Helgeland, Carly Wray, and Bryan Cogman to develop five individual Game of Thrones successor series; the writers were to be working individually with George R. R. Martin, who also co-wrote two of the scripts. D. B. Weiss and David Benioff said that they would not be involved with any of the projects.

Martin said that all the concepts under discussion were prequels, although he believes the term "successor show" applies better to these projects, as they are not Game of Thrones spin-offs in the traditional sense. He ruled out Robert's Rebellion (the overthrow of Daenerys's father by Robert Baratheon) as a possible idea and revealed that some may be set outside Westeros. In September 2018, speaking about the four projects (i.e. not about the Goldman's project), HBO president of programming Casey Bloys said that some of them had been abandoned completely, while others remained as possibilities for the future; Martin said that: "at least two of them are solidly based on material in Fire and Blood". In May 2019, Martin stated that two of the projects were still in the script stage, but were "edging closer". In April 2019, Cogman confirmed his prequel would not be moving forward.

In January 2021, it was revealed that HBO were developing another prequel series to be based on Martin's novella series Tales of Dunk and Egg. Steve Conrad was attached as writer and executive producer of the Tales of Dunk and Egg series in November 2021. Additionally, an animated drama is in development at HBO Max. In March 2021, it was reported that three additional Game of Thrones spinoffs were in development at HBO, they include 10,000 Ships, a reference to the voyages made by warrior queen Princess Nymeria who later founded Dorne, 9 Voyages, about the voyages of Corlys Velaryon on the Sea Snake, and a project based on Flea Bottom, the poorest slum in King's Landing. In July 2021, two more animated series were in development at HBO Max, with one being set in Yi Ti, a nation in Essos based on imperial China.

On June 8, 2018, HBO commissioned a pilot to a Game of Thrones prequel series from Goldman as showrunner and Martin as co-creator. The prequel was to take place in the Age of Heroes, a period that begins roughly 10,000 years before the events of Game of Thrones. Notable events of that period include the foundation of powerful Houses, the Long Night when the White Walkers first descended upon Westeros, and the Andal Invasion when the Andals invaded from Essos and conquered most of Westeros. Martin suggested The Long Night as a title for the series. S. J. Clarkson was announced to direct and executive produce the pilot, while Naomi Watts was cast as the female lead playing "a charismatic socialite hiding a dark secret". Other series regulars were to include: Josh Whitehouse, Toby Regbo, Ivanno Jeremiah, Georgie Henley, Naomi Ackie, Denise Gough, Jamie Campbell Bower, Sheila Atim, Alex Sharp, Miranda Richardson, Marquis Rodriguez, John Simm, Richard McCabe, John Heffernan, and Dixie Egerickx. In September 2019, Martin claimed the pilot was in post-production but in October 2019, it was announced that HBO had decided not to move forward with the series.
