Season 7 of Game of Thrones was announced by HBO on 21 April 2016. In contrast to previous seasons, the seventh season will consist of seven episodes, due to the smaller amount of story content remaining, as well as the increased production values and time required to film episodes involving larger set pieces than in previous seasons.
Like the sixth season, Season 7 will be based on an outline of the two final, presently-unpublished novels in George R.R. Martin's A Song of Ice and Fire series, The Winds of Winter and A Dream of Spring. Filming will commence in September 2016 and continue through February 2017, for a summer 2017 release.
After almost a decade-long summer, Westeros now braces itself for an equally-harsh winter, in more ways than one.
In King's Landing, Cersei Lannister has finally seized the absolute power she long craved. In one swift move, she has eliminated nearly all of her enemies, rivals and obstructions, including Queen Margaery Tyrell, Lord Mace Tyrell, Loras Tyrell, Ser Gareth Mallory, her uncle Kevan, her cousin Lancel, Grand Maester Pycelle, Lucan Blackgard, the High Sparrow and the entirety of the Faith Militant, by destroying the Great Sept of Baelor using large amounts of wildfire. Her three children, Joffrey, Myrcella and Tommen are all dead, Tommen having taken his own life shortly after the Sept's destruction, and thus Cersei has crowned herself the undisputed Queen of the Seven Kingdoms, with Qyburn as her Hand, Ser Roman Mercer as the Lord Commander of both the newly-reformed Blackwatch and her Queensguard, as well as the undead knight Ser Gregor Clegane at her side. After years of serving as the power behind the throne, House Lannister has now become the new royal house. However, Cersei is still haunted by the prophecy she was told about during her childhood, which claimed that the deaths of her children would only predate her own at the hands of a younger and more beautiful queen, making her all the more determined to crush her enemies once and for all.
Despite Cersei's rise to power, the seemingly endless War of the Five Kings continues to ravage the country.
In the Riverlands, the last bastion of King Robb Stark's independent Northern/Riverland Kingdom, Riverrun, has fallen to House Lannister and House Frey, led by Ser Jaime Lannister. Robb's great-uncle, Brynden "The Blackfish" Tully, is dead, having chosen to fight to the death rather than surrender Riverrun, a move that was made possible by his own nephew, Edmure Tully, who ordered the Tully garrison to stand down for the sake of his wife and unborn child. Despite the victory of House Frey, Lord Walder Frey is also dead, having been murdered by Arya Stark for his role in the Red Wedding, leaving the rule of the Riverlands in unknown hands. Also, Sandor "The Hound" Clegane has survived his brutal fight with Brienne of Tarth and attempted to build a new, humble life, but has been dragged back into conflict by the Brotherhood Without Banners, whose numbers also include, shockingly, Rodrik Stark, the thirdborn son of Eddard and Catelyn who was thought to have been killed at the Red Wedding. The Brotherhood have made it clear that they intend to head North to fight in the war that is coming. Brienne and her squire, Podrick Payne, were only barely able to escape the fall of Riverrun, following their failed attempt to recruit the Blackfish to their cause.
On the Iron Islands, King Balon Greyjoy is dead, having been murdered by his psychopathic brother, Euron Greyjoy. Balon's son, Theon, who returned to the Iron Islands after helping Sansa Stark escape from Ramsay Bolton, endorsed his elder sister, Yara, as their father's successor at the subsequent Kingsmoot, but Euron has usurped the Salt Throne with the promise of an alliance with Daenerys Targaryen across the Narrow Sea to help him conquer the Seven Kingdoms. In desperation, Theon, Yara, and their cousin Caspus Harlaw have stolen most of Euron's fleet and sought out Daenerys's help first, and secured an alliance between House Targaryen and Houses Greyjoy and Harlaw to help Daenerys retake the Iron Throne and execute Euron for his crimes. Euron, however, has ordered the construction of an even bigger fleet to destroy all who may stand in his way.
In the aftermath of Cersei's coronation, her cousin, Master of Laws Tybalt Lannister, has fled King's Landing and returned to Casterly Rock. Despite being Cersei's only remaining ally on the Small Council after her walk of atonement, Tybalt now realizes that Cersei has crossed the line and has renounced his allegiance to her. He has made his intentions clear: he plans to rally the lords of the Westerlands in rebellion against her rule.
Also aiding the Targaryens are the Tyrells and the Dornish. In Dorne, Ellaria Sand and the Sand Snakes have staged a coup and murdered Prince Doran Martell and his heir, Trystane, allowing the rulership of Dorne to pass to House Baerley. This was done in retaliation for Doran failing to avenge his dead brother, Oberyn, on the basis that he was killed by Gregor Clegane in a lawful trial by combat. With Cersei declaring war against the Martells for the murder of Myrcella, Ellaria and the Baerleys have turned to Daenerys and her loyalists to bring the Lannisters down. Lady Olenna Tyrell, in response to the deaths of her son, grandson and granddaughter, has also declared for Daenerys, through a meeting with Varys, facilitated by Ellaria.
Most of the strife in the Seven Kingdoms, however, lies at the North. At Winterfell, Roose Bolton is dead, having been murdered by his own son, Ramsay, along with his wife and newborn child, leaving Ramsay as the new Warden of the North and enabling him to solidify alliances with Houses Karstark, Umber, and Nyte, with Rickon Stark as a hostage. At the Wall, following a horrific mutiny, the deceased Lord Commander Jon Snow has been revived by the Red Priestess Melisandre, while Sansa Stark has escaped from Winterfell and Ramsay, to seek shelter with Jon. Having been relieved of his Night's Watch vows, Jon has built an army to retake Winterfell from Ramsay, aided by Ser Davos Seaworth, Tormund, Ser Glendon Estermont, and Lady Lyanna Mormont, and though they have achieved victory and destroyed House Bolton thanks to the Knights of the Vale, courtesy of Lord Petyr "Littlefinger" Baelish, and Grayburn's Legion, led by Dominick Dresden, House Stark's future is left in a questionable position. With Robb and Rickon dead and Bran believed dead as well, the Northern Lords have turned to Jon and named him the new King in the North, while Sansa has rejected Littlefinger's proposal to help him take the Iron Throne and serve as his queen. Given that Littlefinger was instrumental in the outbreak of the war by conspiring with Lysa Arryn to murder Jon Arryn and pit the Starks and Lannisters against each other to throw Westeros into complete chaos, and one of Littlefinger's initial goals was to become the new Warden of the North, Jon's ascension to King in the North is now a major obstacle in Littlefinger's master plan, setting the stage for a looming conflict between Jon and Littlefinger. Melisandre, meanwhile, has been dismissed from Jon's service following the discovery of her role in Shireen Baratheon's death, stripping Jon of easily one of his most valuable advisors, and is now heading to locations unknown.
Lucius Dragen has gone missing. Although many believe that Lucius has been killed by the vigilante Sarina Waters, some still believe that the former Lord of Snake Mount lives. Meanwhile, with Lucius' disappearance, his legitimized bastard uncle, Ethan Dragen, has taken control of House Dragen, all the while undoing the damages Lucius has done to the noble house. However, the Dragens now have to deal with the aftermath of the Lord of the Hunt's "death". Unbeknownst to them, an army of bastards marches onto Snake Mount, led by Lucius' first child and bastard, Lucion Black. Lucius' bastards have formed the House Black, an illegitimate "House of Bastards" made up of at least seven of his baseborn children. Also on the move is Sarina, Lucius' mortal enemy whom many believe was responsible for Dragen's "death", who is now being hunted by the Bastards in Black.
In the Borderlands, House Greyjoy's campaign to attack the Stormlands and the Wastelands have been successfully destroyed thanks to Eddin Blackgard's stern leadership. However, this does not mean that House Blackgard's fight to hold the Borderlands is over. With the destruction of the Great Sept of Baelor and the murder of Eddin's brother Lucan by Roman Mercer on Cersei Lannister's orders, the Blackgards now face a new battle; revenge against House Lannister. Conveniently, the Blackwatch was also responsible for the death of not only Lucan, but of his wife, Jenelyn Harrigon, as well. This means that House Harrigon, the new Lords of Storm's End after a successful Stormmoot, mean to attack King's Landing as well. To this end, the Blackgards and Harrigons have formed an alliance and have both declared for Daenerys Targaryen. With the full might of House Blackgard and House Harrigon supporting the Mother of Dragons, combined with the support of Daenerys' other newfound allies, House Lannister's reign may soon come to an end, and House Blackgard's revenge may soon be fulfilled.
In Brightbank, Lord Hersham Groatworth maintains his dictatorial rule over the village, but continues to face opposition from Lady Jaeneth Grayburn. Unbeknownst to the Grayburns and their loyalists, Hersham has been given orders from Cersei Lannister to create a secret army to subjugate the North under Lannister rule once again. He is unaware that Hendrick Grayburn, the rightful Lord of Brightbank, is returning to the North with an army of bordermen, ready to reclaim Brightbank for House Grayburn.
In the Reach, despite having to brave various obstacles, Samwell Tarly and his surrogate family, Gilly and her son, have finally reached the Citadel in Oldtown, where Sam intends to train as a maester to gain some insight into the White Walkers and how to defeat them. However, with Sam's theft of his family's ancestral Valyrian steel sword, Heartsbane, he will have undoubtedly incurred the immense wrath of his father; Randyll Tarly will now likely seek retribution, so Samwell must use the sword in his studies and uncover the secrets behind Valyrian steel for the coming battle against the dead, before all is lost.
In Braavos, though Arya Stark has regained her sight and favor with the Faceless Men, her code of honor has put her at odds with the guild, causing her to botch an assassination attempt on an innocent target. Despite almost being killed, Arya has escaped Braavos with her life and returned to Westeros, beginning her vengeance for her family by murdering Walder Frey and his sons, Lame Lothar and Black Walder, for orchestrating the Red Wedding that claimed the lives of her brother and mother. Arya, now possessing some of the Faceless Men's unusual techniques, sets about crossing off more names on her list of vengeance.
Across the Narrow Sea, after having finally defeated the Slave Masters and the Sons of the Harpy and acquired an army made from the Dothraki, the Unsullied, the Golden Empire of Yi Ti, Houses Greyjoy, Harlaw, Blacktyde, and Goodbrother, House Tyrell, the Knights of Aegon led by Carmine Grayburn, the Windblown, and Braavos, Queen Daenerys Targaryen has finally set sail for Westeros, with Tyrion Lannister at her side as her Hand of the Queen, though at the cost of two of her advisors: Jorah Mormont, whom Daenerys has sent to find a cure for his spreading greyscale infection, and Daario Naharis, her lover whom Daenerys has ordered to stay behind with the Second Sons on Tyrion's advice so that she may pursue a marriage alliance to aid her in her campaign. The Mother of Dragons now prepares herself for a clash of queens unlike anything Westeros has ever seen. Unknown to Daenerys, however, there is somebody across the Narrow Sea who may very well have a stronger claim than her to the Targaryen monarchy, setting the stage for either a strong allegiance or another civil war within House Targaryen.
Beyond the Wall, Bran Stark has been training in his powers in greensight under the tutelage of the Three-eyed raven and learned some devastating secrets, such as origin of the White Walkers and the true parentage of his half-brother, Jon Snow: he is the son of Lyanna Stark and Rhaegar Targaryen, which would make him the nephew and a rival claimant to Daenerys Targaryen for the Iron Throne. Following an attack which claims the lives of the Three-eyed raven, Hodor and the last of the Children of the Forest, Bran and Meera Reed have been rescued by Bran's undead uncle, Benjen Stark, and taken back to the Wall to prepare for the arrival of the Night King, who at all costs must be defeated before Westeros can dream of another spring. Helping him finish the last stages of his training are Tregar Blackgard, an ancient and long-forgotten ancestor of House Blackgard, who continues to guide the young Bran even after he leaves the lands beyond the Wall, and Aenir Targaryen, a lost prince of the Targaryen dynasty who has vowed to become Bran's protector. Both Tregar and Aenir warn the young greenseer that, since the Walkers now know of Bran's existence and purpose, they won't hesitate to hunt him down a second time.
El Punt Avui reports that Season 7 will not return to Girona for filming. However, Fresco Films has been scouting Spain for several locations containing "castles." There have also been reports of a significant number of battles taking place in and near these castles.  The Spanish locations have been confirmed so far are: Seville, Caceres, Almodóvar del Rio, Santiponce, Zumaia and Bermeo.
Producers David Benioff and D.B. Weiss have confirmed that season seven will be both filmed and released later than past seasons of Game of Thrones. This is mainly due to the desire to accurately depict the winter that now grips Westeros.
