HBO’s A Knight of the Seven Kingdoms introduces fans to a new chapter of Westeros, but with it comes a familiar challenge: keeping track of the sprawling Targaryen family tree. While the series focuses on lowborn knight Ser Duncan “Dunk” the Tall (Peter Claffey) and his squire Egg (Dexter Sol Ansell) at the Ashford Meadow tournament, the Targaryens quickly enter the story, bringing their trademark drama—and plenty of “ae” names—to the forefront.

At the top of the family tree is King Daeron II Targaryen, the great-grandson of Rhaenyra and Daemon Targaryen from House of the Dragon. Known as “Daeron the Good,” his reign brought peace to Westeros roughly 80 years after the events of House of the Dragon. He ended the Blackfyre Rebellion and peacefully integrated Dorne into the Seven Kingdoms, setting the stage for the political landscape seen in A Knight of the Seven Kingdoms.

Daeron II and his wife, Dornish Princess Myriah Martell, have four sons, but the series focuses mainly on Baelor “Breakspear” Targaryen and Maekar Targaryen.

• Prince Baelor “Breakspear” Targaryen (Bertie Carvel): The eldest son, Baelor is heir to the Iron Throne and Hand of the King. Known for his wisdom and fairness, Baelor has two sons with his wife Jena Dondarrion—Valarr (Oscar Morgan) and Matarys—with Valarr appearing in the series. Interestingly, Baelor’s darker hair reflects his Dornish heritage rather than the Targaryens’ traditional silver locks.
• Prince Maekar Targaryen (Sam Spruell): The Prince of Summerhall is harsher than his brother and has six children with Dyanna Dayne. The show highlights his sons Daeron, Aerion, and Aemon, while his daughters Daella and Rhae are largely left out.
  • Daeron (Henry Ashton), known as Daeron the Drunken, possesses the prophetic dragon-dreaming gift seen in select Targaryens, linking him to Helaena from House of the Dragon.
  • Aerion (Finn Bennett), dubbed “Aerion Brightflame,” embodies the Targaryen madness. Believing himself to be a living dragon, he is both cruel and flamboyant, with a signature fiery helmet.
  • Aemon, later known as Maester Aemon of Castle Black in Game of Thrones, is still studying in Oldtown during the events of this prequel, providing a tangible connection between the two series.

While A Knight of the Seven Kingdoms centers on Dunk and Egg, understanding the Targaryen lineage deepens the story, illustrating the complex web of power, prophecy, and personality that defines House Targaryen. From the benevolent Daeron II to the unpredictable Aerion, the family’s dynamics continue to shape Westeros and set the stage for future conflicts in the Seven Kingdoms.

This Targaryen map not only helps viewers keep track of relationships but also highlights how prequel narratives link to both House of the Dragon and Game of Thrones, offering longtime fans a richer, more connected world to explore.
