The knights in the Kingsguard play a vital role in House of the Dragon.

At present, Ser Harrold Westerling (Graham McTavish) has served King Viserys I Targaryen (Paddy Considine) loyally as Lord Commander, while Ser Criston Cole (Fabien Frankel) has gone from being the sworn protector and lover of Princess Rhaenyra Targaryen (Emma D’Arcy) to the right-hand man of Queen Alicent Hightower (Olivia Cooke).

However, two rather memorable knights of the Kinsguard are set to play an even more important role in the events to come: Ser Arryk Cargyll and Ser Erryk Cargyll.

Yet, who plays these characters in House of the Dragon?
