The adaptation of the book series "A Song of Ice and Fire" into a television series has brought many changes and adjustments. The following text focuses on specific deviations and inconsistencies between the books and the series, including misrepresentations of historical events, misassigned characters, and inaccurately portrayed scenes.
- Queen Alysanne was hosted by Lord Alaric Stark, not Rickon Stark. Also with her did not come King Jaehaerys.
- Queen Alysanne's dragon, Silverwing, is the only dragon mentioned that would not fly over the wall. Jaehaerys never attempted to do so with Vermitor (he was not present in the North at that time, having stayed in King's Landing to help mediate a dispute between the Archdeacon of Tyros and the Prince of Pentos).
- Rhaenyra did not venture into the Stormlands to search for Lucerys' remains
- In the books, it was Arrax's severed head and neck that washed up in the sea near Storm's End, not one of his wings.
- In the books, Otto never publicly or privately praised Aemond's actions over Shipbreaker Bay. Instead, he scolded Aemond and shouted, "You only lost one eye. How could you be so blind?", knowing that Aemond's murder of Lucerys had destroyed any chance of the Blacks accepting a peaceful solution.
- It is Jace, not Daemon, who referred to Vhagara as "a hoarse old bitch".
- Alyn and Addam of Hull did not work for the Velaryon fleet, but served on their mother's merchant train. Alyn did not save Corlys' life during the Stepping Stones War, which ended the same year he was born.
- Alyn is described as having silver hair and violet eyes.
- Floris Baratheon was not engaged to Aemond, but to Larys Strong.
- There is no mention of Alicent sending letters of apology to Rhaenyra.
- There is no character named Jerard in the books.
- Grover Tully is not described as fat.
- There is no mention or allusion to Alicent and Criston Cole having a sexual relationship.
- Hugh lived at Dragonstone, not King's Landing.
- There is no indication that Larys Strong convinced Aegon to remove Ota from his position as Hand of the King.
- Jeyne Arryn asking for a dragon to guard the Vale in exchange for her loyalty is one of two possibilities put forward, which come from Grandmaster Munkun's True Narrative. Munkun's narrative is generally considered more reliable than the other, from the testimony of the foolish Dove, who claims that the Lady Arryn offered her allegiance to Jace if he would bring her to climax with his tongue.
- Alicent's mother is never named in the books.
- Daemon did not order Rhaenys to with him to go kill Vhagar.
- Blood was not currently a member of the City Watch during the Dance of the Dragons. He was dismissed from the Patrol after he beat a whore to death in a drunken rage.
- There is no mention of Blood having a personal vendetta against House Hightower, nor that Chiza was motivated by the prospect of paying off his gambling debts.
- Daemon did not hire Blood and Cheese to carry out the murder personally, but through an intermediary, a pale stranger who turned out to be Mysaria.
- Mysaria did not leave King's Landing and she was not arrested by Daemon or anyone else.
- Krev did not use violence against Cheese.
- At this point in the story, Aegon and Helaena already had two sons, not just one. The younger, Maelor, was also present at the murder of his older brother Jaehaerys, along Jaehaera, Helaena, and Alicent. Blood and Cheese tied up and silenced Alicent (along with killing one of her maidservants to prevent her from raising the alarm, and the Queen's guards) and held her and Helaena's children hostage, forcing Helaena to choose her son to be killed. When she hesitated, Cheese warned her that Blood might get bored and rape Jaehaeru. Helaena crying, chose Maelor with the reasoning that he would be too young to understand what was going on (or perhaps because Jaehaerys was the firstborn son and heir of King Aegon). Cheese then laughed at Maelor and told him that his mother wanted him dead, and grinned at Bloody, who proceeded to chop off Jaehaerys' head with a single sword stroke. The pair then fled i s Jaehaerys' head while Helaena screamed.
- Helaena did not try to bribe the assassins, instead begging them to kill her instead, but they refused.
- The books do not state how old Erryk and Arryk Cargyll were when they joined the Kingsguard.
- The books make no mention of Torrhen Stark or anyone else initiating the tradition of sacrificing every tenth man of House Stark to the Watch.
- Torrhen Stark bent the knee to Aegon the Conqueror, not because he believed that Aegon could unite the seven kingdoms, but because he had received news of Aegon's victories (particularly the burning of Harrenhal and the Field of Fire) and decided that fighting the Targaryens would be futile.
- The encounter between Aegon the Conqueror and Torrhen Stark, during which the latter bent the knee to the former, took place not on the Wall, but on the south bank of the Trident.
- There is no mention in the books that Cheese had a dog.
