Olivia Cooke as Alicent Hightower. She’s 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.
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.
