Like his father, he is deeply respected and considered wise and fair. He has two sons with his wife Jena Dondarrion: Prince Valarr (Oscar Morgan) and Prince Matarys, but only Valarr appears.

Maekar and his wife Dyanna Dayne have six children together: Daeron, Aerion, Aemon, Daella, Aegon and Rhae. Knight of the Seven Kingdoms mainly focuses on her sons, leaving Daella and Rhae out of the story.
His first son, Daeron (Henry Ashton), is also known as Daeron the Drunken, and has the gift of dreaming of the chosen dragon of the Targaryens. The House of the BeastHelaena Targaryen has a similar gift.
Maekar’s second son, Aerion (Finn Bennett), fits the bill for a classic Targaryen “madman”. Thinking he is a dragon in human form, he calls himself “Aerion Brightflame” and wears a flaming helmet, which means he is very ill. However, her fashion choices cannot cover up her cruelty and sadness.
Game of Thrones fans have already met Maekar’s third son Aemon: He is none other than Maester Aemon of Castle Black. Don’t expect to see him in Season 1 Knight of the Seven Kingdomshowever, as he is currently studying to get the master chain in Oldtown. However, his presence in the world Knight of the Seven Kingdoms it serves as a reminder of how the show connects Game of Thrones, their events are less than a century apart.
As episode 3 of Knight of the Seven Kingdoms revealed, Maekar’s fourth son, Aegon, is none other than Egg himself. He’s been going Dunk all this time, and has shaved his head bald to hide his trademark Targaryen hair. Based on the show so far, Aegon has missed the sad streak of his brother Aerion, or of his many Targaryen ancestors. Instead, she is curious, loyal, and protective of the little people Dunk meets in Ashford Meadow. Yes, he is still young, and there is definitely time for the world to strengthen him, but for now, he is a good egg.
New episodes of Knight of the Seven Kingdoms premieres Sundays at 10 pm ET on HBO and HBO Max.
Update: Feb. 1, 2026, 10:47 pm EST This story was published on Jan. 18. Updated to reflect the reveal of Egg’s true identity as Aegon Targaryen.
