The world of Westeros keeps expanding on screen, but only one member of the Targaryen family tree has managed to appear in every single live-action show set in this universe. With the arrival of the newest HBO spin-off A Knight of the Seven Kingdoms, fans are discovering that a single character connects the Dance of the Dragons era all the way to Daenerys Targaryen’s story.
That character is Aemon Targaryen. But before you get confused, this is not the same Aemon from House of the Dragon who lost an eye. This is Maester Aemon, the blind old man from the Night’s Watch who mentored Jon Snow in the original Game of Thrones series. And here is the surprising part — he is also a key off-screen figure in the latest spin-off that just premiered.
Who is the Targaryen that bridges all three shows?
The answer is Aemon Targaryen, but understanding his place in the timeline explains why he is so special. In Game of Thrones, viewers met him as an elderly maester at Castle Black. He was kind, wise, and one of the few people who knew Jon Snow’s true value long before anyone else.
What the original show did not fully explain was his royal background. Maester Aemon was actually a prince of the Targaryen dynasty. He was the older brother of Aegon V Targaryen, who is the main Targaryen character in the new series A Knight of the Seven Kingdoms.
In the books, Aemon was the one who gave his little brother the nickname “Egg.” That young boy, Aegon, grows up to become king, and his descendants include the Mad King Aerys and eventually Daenerys Targaryen. So Aemon, who chose a life of service over the throne, lived long enough to see his family nearly destroyed.
Aemon’s role in the new series A Knight of the Seven Kingdoms
The new HBO show A Knight of the Seven Kingdoms premiered on January 18, 2026, on HBO and is streaming on HBO Max . It is set about 100 years before Game of Thrones and follows the adventures of Ser Duncan the Tall (Peter Claffey) and his young squire Egg (Dexter Sol Ansell), who is actually Prince Aegon Targaryen in disguise .
While Maester Aemon does not physically appear in the first season of the show, his presence is felt. In the source material, it was Aemon who gave Egg his nickname because he thought his little brother displayed a sweet and innocent nature . Fans of the original series will remember that on his deathbed in Game of Thrones, an old and failing Maester Aemon called out for his brother, saying, “Egg, I dreamed that I was old” . That emotional moment now carries much more weight because viewers will soon see young Egg in his own series.
The actor playing young Egg, Dexter Sol Ansell, has been praised by showrunner Ira Parker as “the best child actor on planet Earth” . The show also features a host of Targaryen characters including Finn Bennett as the cruel Prince Aerion “Brightflame” Targaryen, Sam Spruell as Prince Maekar Targaryen (the father of Aemon and Egg), and Bertie Carvel as Crown Prince Baelor “Breakspear” Targaryen .
How Aemon connects to House of the Dragon
The connection does not stop with the original show and the new spin-off. Maester Aemon is also directly linked to the characters in House of the Dragon, which is set about 200 years before Game of Thrones.
Aemon is a direct descendant of Rhaenyra Targaryen. Through his lineage, he comes from Rhaenyra and Daemon’s son, Viserys II Targaryen . This means that the civil war viewers are watching in House of the Dragon directly impacts the family line that produces both Aemon and his brother Egg.
In fact, all the Targaryens appearing in A Knight of the Seven Kingdoms come from Rhaenyra’s side of the family, not from Alicent Hightower’s children . So when fans watch the new show, they are seeing the descendants of the “Black” faction from the Dance of the Dragons.
Why this matters for fans watching all three shows
Understanding these connections makes watching all three series a richer experience. When Aemon talks about his brother Egg in Game of Thrones, he is referring to the young boy viewers now get to watch grow up in the new series. And when fans see the Targaryen civil war in House of the Dragon, they are watching the events that shape the family that eventually produces both Aemon and Egg.
The timeline works like this: House of the Dragon takes place around 200 years before Game of Thrones. A Knight of the Seven Kingdoms is set roughly 100 years before the original show, placing it right in the middle . Aemon was born during this middle period, lived through the events of A Knight of the Seven Kingdoms as a young man, and then lived all the way to the time of Game of Thrones.
That means one character’s lifetime spans the entire on-screen history of Westeros so far.
What we know about A Knight of the Seven Kingdoms release
For those wanting to start watching, the first season of A Knight of the Seven Kingdoms consists of six half-hour episodes. It premiered on January 18, 2026, at 10:00 p.m. ET/PT on HBO and is available to stream on HBO Max . In the UK, it airs on Sky Atlantic and NOW from January 19, 2026 .
The show is based on George R.R. Martin’s novella The Hedge Knight, the first of the Dunk and Egg stories . A second season has already been confirmed and will adapt the next novella, The Sworn Sword, with production underway for a 2027 premiere .
The cast includes Peter Claffey as Ser Duncan the Tall, a former Irish rugby player turned actor who has appeared in Bad Sisters and Vikings: Valhalla . Dexter Sol Ansell plays Egg, and fans might recognize him as a young Coriolanus Snow in The Hunger Games: The Ballad of Songbirds & Snakes .
The Targaryen family tree explained simply
For those trying to keep track, here is how it all connects:
- Rhaenyra Targaryen (from House of the Dragon) → her son Viserys II → several generations later → Maekar I Targaryen (appears in A Knight of the Seven Kingdoms) → his sons include Aemon (the maester) and Aegon V (Egg)
- Aegon V (Egg) → his grandson is Aerys II (the Mad King) → Aerys II is the father of Daenerys Targaryen, Rhaegar Targaryen (Jon Snow’s father), and Viserys (her brother)
So Aemon, who never took the throne, was the great-uncle of the Mad King and the great-great-uncle of Daenerys. He lived through the fall of his dynasty and still chose to serve the realm until his death at a very old age.

What makes this Targaryen different
Unlike most of his family members, Aemon Targaryen was never interested in power. When he was a young man, he was passed over for the throne several times due to succession laws, but he had already chosen to become a maester. Maesters give up their family names and titles, so he willingly set aside any claim to the Iron Throne.
This makes him unique among the Targaryens we have seen on screen. While his relatives fought and died for power, Aemon lived a long life serving others. He ended up at the Wall, far from the political games of King’s Landing, and died surrounded by brothers of the Night’s Watch rather than scheming lords and ladies.
In Game of Thrones, he told Jon Snow, “Love is the death of duty.” That line comes from a man who loved his family but chose his duty instead.

So whether you are watching the dragon battles in House of the Dragon, the adventures in A Knight of the Seven Kingdoms, or rewatching Jon Snow’s journey at the Wall, remember that one old maester connects them all. For more updates on Game of Thrones universe, keep reading VvipTimes.
