Rhaenyra - who is the daughter of Viserys and his first wife, Aemma Arryn - is played by Australian actress Milly Alcock in the opening episode of the series and flashbacks, while Emma D'Arcy plays an aged-up version of the character for the rest of the series.

Rhaenyra is Daenerys' ancestor

Rhaenyra's father is the fifth Targaryen ruler of the Seven Kingdoms, making him the great, great, great-grandson of Aegon the Conqueror, the first Lord of the Seven Kingdoms and inhabitant of the Iron Throne.

And although Rhaenyra and Daenerys bear a very strong resemblance, they are only distantly related. There are a dozen Targaryen rulers between King Viserys I and Aerys II (Daenerys' father, who later became known as the Mad King, meaning that Rhaenyra is Daenerys' great, great, great, great, great, great grandmother.

However, their relation to one another is a little bit more complicated due to the incestuous practice in the Targaryen house of marrying sister and brother to keep the bloodline pure. As a result, Rhaenyra and Daenerys are also first cousins seven times removed.

In the first episode of House of the Dragon, we see Rhaenyra is only named heir to the Iron Throne at the age of eight after her father struggles to conceive a male heir. As a result, she grows up assuming she will eventually be crowned Queen of Westeros - something that has never been done before.
