The recordings of the third season of House of the Dragon are already underway, and with that, three more important names were announced, faces that we know from several other series. After all, the Dance of the Dragons is not just a war of succession—it is a conflict that tests what it means to be loyal, noble, and useful to a crown that devours its own defenders.

Tom Cullen (Knightfall and Becoming Elizabeth), Joplin Sibtain (Andor), and Barry Sloane (Sandman) have joined the cast and are now officially part of the Game of Thrones universe, promising to be in remarkable scenes in the story.

Cullen will play Ser Luthor Largent (who should have appeared in both seasons by now, but oh well), Sibtain will play Ser “Bold” Jon Roxton. Sloane will play Ser Adrian Redfort, who ends up being distorted reflections of each other: the traitor out of pragmatism, the martyr out of idealism, and the knight out of duty. Their destinies intersect with the fire of dragons, but are forged in the silence of broken oaths and spears stuck in the earth. I’m inspired [laughs]

The truth is that these characters promise to expand even further the human dilemmas of the Targaryen civil war, because, in the end, it is the common men who sustain the shadows of the dragons.

The duplicity – but also loyalty – to Daemon and Rhaenyra

With two new names, the confirmation of Tom Cullen as Ser Luthor is extremely interesting because he, SPOILER ALERT, turns against the Greens, kills Gwayne Hightower (Freddie Fox) and, depending on the series’ version, will also be implicated in the highly suspicious death of Helaena Targaryen (Phia Saban).

Ser Luthor Largent is a name that resonates between the lines of Fire & Blood as one of the men who carried the weight of loyalty on their shoulders – albeit to the wrong side of history, depending on who tells it. A Knight of the Kingsguard during the end of the reign of Viserys I Targaryen (Paddy Considine), Largent was known for his imposing stature and almost legendary physical strength. Fierce, burly, and disciplined, he was not only a man-at-arms but a symbol of the brute force that upheld the order of the Iron Throne.

When King Viserys I died, the line of succession should have been clear: his daughter Rhaenyra, named heir by royal decree and oath of the entire court, including the Kingsguard, was destined for the throne. But in the silence of the royal chambers and in the shadows of power, a silent coup was being planned. Ser Luthor Largent was supposed to be in the picture in Season 1 because he was among the seven who formed the core of the Kingsguard, and among the few who knew immediately of the king’s death. So he chose at that moment to side with the greens, supporting the ascension of Aegon II Targaryen (Tom Glynn-Carney) to the throne, even if it meant breaking his oath to protect the rightful heir.

Largent’s decision was both pragmatic and political. He was a man of action, and the greens, led by Ser Criston Cole (Fabien Frankel) and Queen Alicent Hightower (Olivia Cooke), did not hesitate to act. In the days following Viserys’s death, while Rhaenyra (Emma D’Arcy) remained aloof on Dragonstone, Largent helped keep the king’s death a secret from the Red Keep. The plot culminated in the impromptu coronation of Aegon II at Baelor, before Rhaenyra could even claim the throne. It was a defining moment—and Ser Luthor Largent was there, as a guard, a force, a traitor, depending on whose side you’re on.

In the television adaptation, the casting of Tom Cullen in the role promises to bring additional layers to this figure, who, although secondary in the book, represents the moral and political dilemmas that plague all the characters in Westeros: honor versus pragmatism, oath versus survival. If the series follows the text, we’ll see Largent play a key role behind the scenes of the coup, perhaps even more prominent than in the records of the masters and chroniclers, giving face and emotion to one of the guards who shaped the beginnings of the Dance of the Dragons.

SPOILER ALERT

In the book, Luthor was captain of the City Watch, that is, he worked directly with Daemon (Matt Smith) and commanded one of the seven city gates. But when the Greens took power, he was promoted to Commander and was seen by the council as the most fearsome of the officers sympathetic to the cause of Prince Aegon Targaryen. Still, the Hand of the King, Ser Otto Hightower (Rhys Iphans), distrusted him and so appointed his son, Ser Gwayne Hightower, as Luthor’s second to watch over him. All of this has been eliminated from the narrative so far.

Among Ser Luthor’s several significant participations in the story is proving that Otto was right because he changes sides during the fall of King’s Landing in loyalty to Daemon. In a typical war move, Luthor personally kills Gwayne, and as a reward, is made a Ser by Rhaenyra, forming House Largent.

Later, when Helaena commits suicide, rumors were that Ser Luthor threw her out of the window on Rhaenyra’s orders, but there is also testimony that he was in the barracks, with three hundred men in gold cloaks, so he could not have participated in the crime.

When the riots in the city begin, it is Ser Luthor who leads the resistance for the Crown and tries to stop the Shepherd, the religious leader who incites the population to kill all the dragons. But, not only does he not arrest the Shepherd, but the crowd begins to attack the guards. Even trained, the men were a minority and are decimated.

In the confusion, Luthor is pulled from his horse, stabbed, and beaten to death to the point that his face is completely destroyed.

From Andor to House of the Dragon

Ser Jon Roxton, nicknamed “Bold” Jon Roxton, will be played by Joplin Sibtain, who we now know as Brasso from Andor. In House of the Dragon, Roxton is a crucial figure in the power play and violence that marks the Targaryen civil war. His nickname, “Bold” (bold, courageous), is not only an allusion to his bravery in battle, but also to his fierce, impetuous and loyal nature to the end — a man who lives by the sword and dies for his cause. In this case, that of the Greens.

Ser Jon fought alongside Aegon II and, after the death of Lord Ormund Hightower (James Norton) at the First Battle of Tumbleton, Jon will attempt to assume leadership of the Hightower army. He also “claims” Lady Sharis Footly as a “war prize” after killing her husband.

As hot-tempered as he was, Jon was among those who wished to advance quickly on King’s Landing after the Taking of the Dragonpit and Rhaenyra’s escape from the capital. Other green leaders, however, were cautious, and the host remained at Tumbleton.

When Ser Ulf White and Ser Hugh Hammer demanded Highgarden and the Iron Throne, respectively, Jon joined the Caltrops conspiracy, which sought the death of the dragonriders. During the Second Battle of Tumbleton, Jon killed Hugh Hammer when he least suspected it, slicing him open from groin to throat with his sword. Shortly afterward, he was attacked by a dozen of Hugh’s men, but managed to kill three of them. Legend has it that Jon slipped on Hugh’s entrails before he was finally killed.

One of Rhaenyra’s protectors

Ser Adrian Redfort will be one of the Kingsguard once Rhaenyra takes the Iron Throne, and will be at her side when she is surprised – and killed – by Aegon at Dragonstone. He was killed by Ser Alfred Broome’s men defending his Queen, stabbed in the back with a spear.

In short, they are vital characters in the third part of the story.
