HBO’s new prequel of Dunk & Egg after the House of Dragon set to release soon with a good storyline of Aegon Targaryen “Egg” the price belongs to the lineage of Rhaenyra. A Knight Of The Seven Kingdoms is set in the era 90 years before Game of Thrones, in the time of King Daeron II. Actually, young Egg is the great-great-great-grandson of Rhaenyra by way of her son Viserys II.
So the A Knight Of The Seven Kingdoms directly connected to people from GoT and House of the Dragon. Daeron II – Egg’s grand-uncle and the series’ ruling king – would gain the epithet “Daeron the Good”.
Aegon V “Egg” Targaryen
Dexter Sol Ansell is cast as Aegon V Targaryen, “Egg”, the young prince in the trailer. Egg is introduced as a boy prince of House Targaryen, the fourth son of Prince Maekar. He is a brave, compassionate, and intelligent young man in Martin’s novels.
He shaves his head and wears a loose cap to conceal his silver-gold hair, so as not to be recognized by common men. For those of you who can’t imagine him, imagine Iggy Pop with silver gold hair. People say of him that even as a grown man he was warm and easy to approach, and loved by the smallfolk.
The trailer shows Egg with large, pure eyes and a fast smile, just as the kind and clever boy from the novels.
Prince Aerion “Brightflame” Targaryen
Finn Bennett as Aerion “Brightflame” Targaryen, Egg’s older brother with platinum hair. In the books, Aerion is pure evil. He was portrayed as The Monstrous Aerion due to his cruel and arrogant nature. He actually believes he’s a dragon trapped in a man’s body, according to Westeros, One synopsis tags him as ‘a classic case of Targaryen family madness’, In the Dunk & Egg stories, he dabbles in evil magic and bullies Egg—such as by throwing Egg’s pet cat in a well.
Bennett’s version has a helmet clad in metal flames inspired by his fire-loving ego. Aerion is, at the end of the day, the show’s crazy prince. The trailer nails his wild, sneering vibe that suits his brutal, flame-loving nature.
Prince Daeron “The Drunken” Targaryen
Henry Ashton plays Prince Daeron Targaryen, the elder brother of Egg and Aerion. Daeron is Maekar’s eldest – in fact, the official notes describe him as “the eldest son of Maekar, I… the prince of Westeros”
The following Maekar he would have been next in line to sit on the throne. His sobriquet “the Drunken” reflects his method of dealing with two prophetic visions: in the novels Daeron drinks wine to numb family tension in the Targaryen brood is a family secret. The Direct also confirms Daeron’s identity: he “is the son of Maekar I, and is… the prince of Westeros, and the crown’s next-in-line after Maekar”
From Ashton’s Daeron grin and swagger it is immediately clear that this Daeron is a roguish and charismatic man of mystery. We only see him for a moment in the trailer, but the “Drunken” prince has a lot more going on than you’d think.
Prince Aemon Targaryen
Aemon Targaryen is Egg’s eldest brother. He appears later in life as Maester Aemon in Game of Thrones. He is not going to show up in the Dunk & Egg series. At this stage, young Aemon already is in the Citadel. Still, he waits in the wings. Aemon was the elder brother of Egg. He became a maester and then joined the Night’s Watch. In the Dunk & Egg tales, Aemon dubs his brother the nickname “Egg.”
He really looks up to him. In the Game of Thrones deathbed, Maester Aemon has visions of Egg. Martin’s background says young Aemon saw Egg’s “sweetness and innocence.” So, while scholar Aemon never takes the stage, he is family. He quietly shaped Egg’s beginnings, if never announced himself to modern readers.
Prince Maekar I Targaryen
Sam Spruell is cast as Prince Maekar, the father of Aerion, Daeron, Aemon, and Egg. Take a look at him. The trailer shows him as a no-nonsense military leader. SoapCentral mentioned Maekar fought terribly hard in the Blackfyre Rebellions. He was dubbed “the Anvil” because he held his ground in the midst of chaos. Maekar is a strong and grumpy in the attitude. The books say he is irritable and impatience, difficult man with a sharp tongue and who was too quick to find fault or to punish. After killing his brother Baelor by accident in a tourney, he becomes even more severe. But he loved his children in his rugged way. In The Hedge Knight, he allows Egg to be squire to Ser Duncan. He lays down the laws: keep out of sight and look meek. No locking Egg up instead. So Spruell’s Maekar should be strict, but with a heart. A proud Targaryen dad worries about his wild boys.

Prince Baelor “Breakspear” Targaryen
Bertie Carvel is cast as Prince Baelor Targaryen. He is the uncle of Egg and the eldest son of Daeron II. In the stories, Baelor is the quintessential heroic prince. His moniker is well-earned – he gave Daemon Blackfyre’s spear a good snapping in a tournament. Then he was Hand of the King. His mercy and Knightly life was beloved of the people. An ancient writing says it all: “It is beyond question that Baelor Breakspear would make an excellent king. He was chivalrous and had a good mind.”
King Daeron II Targaryen
King Daeron II never appears on screen, but he sired a lot of these characters. Known as “Daeron the Good,” he reigned with wisdom and prudence in negotiations. He married Princess Myriah Martell and had four sons: Baelor, Aerys, Rhaegel, and Maekar. Baelor, Maekar, and even Egg, all come back to Daeron’s Targaryen line. This line goes from Viserys II to Rhaenyra’s line, and connects the princes to the Targaryens of House of the Dragon. Daenerys from “Game of Thrones?” She’s just formed one part of one side line from Egg’s great-great- granddaughter.
Princes such as the brave Baelor and the volatile Aerion share blood with the Dragon Queen. Their stories contribute to the larger Targaryen narrative.
