The Season 1 finale of A Knight of the Seven Kingdoms confused viewers by mentioning nine kingdoms in Westeros instead of seven. This detail stems from historical changes in the continent's political divisions. The planned Aegon's Conquest spinoff will provide on-screen clarification of this lore.
In the finale of A Knight of the Seven Kingdoms Season 1, the character Egg corrects Dunk, stating there are nine kingdoms, not seven, accompanied by a title card reading “A Knight of the Nine Kingdoms.” The series title remains unchanged, but the reference puzzled audiences unfamiliar with George R.R. Martin’s books.
The term “Seven Kingdoms” originated before Aegon’s Conquest, an event occurring about 209 years prior to the series' timeline. Aegon the Conqueror, along with his sister-wives Rhaenys and Visenya, arrived from Dragonstone on three dragons to unify mainland Westeros, then divided into seven kingdoms. These included regions ruled by various houses, though the landscape had previously featured up to 100 kingdoms.
Dorne successfully resisted the conquest, leading Aegon to be titled “Lord of the Seven Kingdoms” for symbolic reasons tied to the Faith of the Seven, where seven holds cultural significance in Westeros. Post-conquest, House Tully received rule over the riverlands, separating it from the Iron Islands assigned to the Greyjoys. The area around King’s Landing emerged as the eighth major region, the crownlands, while some territories were renamed.
The upcoming Aegon’s Conquest prequel, scripted by Mattson Tomlin, may take the form of a TV series or films. It will depict the pre-conquest divided Westeros and the Targaryen unification process, featuring rulers of individual regions. However, it cannot cover Dorne’s integration as the ninth kingdom, which occurred 161 years after the conquest—still within the timeframe for Egg’s reference nearly 50 years later in A Knight of the Seven Kingdoms.
All six episodes of A Knight of the Seven Kingdoms Season 1 are available on HBO Max, with Season 2 slated for 2027.
