Emma D’Arcy as Princess Rhaenyra Targaryen: The king’s first-born child, she is of pure Valyrian blood, and she is a dragonrider. Many would say that Rhaenyra was born with everything… but she was not born a man.

Steve Toussaint as Lord Corlys Velaryon (“The Sea Snake”): Lord of House Velaryon, a Valyrian bloodline as old as House Targaryen. As “The Sea Snake,” the most famed nautical adventurer in the history of Westeros, Lord Corlys built his house into a powerful seat that is even richer than the Lannisters and that claims the largest navy in the world.

Olivia Cooke as Alicent Hightower: The daughter of Otto Hightower, the Hand of the King, and the most comely woman in the Seven Kingdoms. She was raised in the Red Keep, close to the king and his innermost circle; she possesses both a courtly grace and a keen political acumen.

Rhys Ifans as Otto Hightower: The Hand of the King, Ser Otto loyally and faithfully serves both his king and his realm. As the Hand sees it, the greatest threat to the realm is the king’s brother, Daemon, and his position as heir to the throne.

Sonoya Mizuno plays Mysaria. She came to Westeros with nothing, sold more times than she can recall, and could have wilted…but instead she rose to become the most trusted — and most unlikely — ally of Prince Daemon Targaryen, the heir to the throne.

Fabien Frankel portrays Ser Criston Cole. Of Dornish descent, Ser Criston is the common-born son of the steward to the Lord of Blackhaven. He has no claim to land or titles; all he has to his name is his honor and his preternatural skill with a sword.

Paddy Considine will play King Viserys Targaryen, who was chosen by the lords of Westeros to succeed the Old King, Jaehaerys Targaryen, at the Great Council at Harrenhal.

Eve Best plays Princess Rhaenys Velaryon. A dragonrider and wife to Lord Corlys Velaryon, “The Queen Who Never Was” was passed over as heir to the throne at the Great Council because the realm favored her cousin, Viserys, simply for being male.
