King Viserys Targaryen - Played by Paddy Considine
Viserys was chosen by the lords of Westeros to succeed the Old King, Jaehaerys Targaryen, at the Great Council at Harrenhal.
A warm, kind, and decent man, Viserys only wishes to carry forward his grandfather’s legacy, but as we’ve learned from Game of Thrones, good men do not necessarily make for great kings.
Talking about Viserys at Comic Con, Paddy said: “He’s a kind man. He inherited the crown because he was a good scholar, a man of good temperament and a kind man. He’s trying to keep peace time going in the kingdom. That’s why he was chosen as king.
“I wanted to imbue him with as much humanity as I could. He’s a man who cares about things. There’s great tragedy in him. He loves his family. He’s also carrying a great secret in him that’s revealed in the show that refers to the potential fall of man in the future.”
Paddy Considine's incredible run of TV shows and movies includes Dead Man's Shoes, Hot Fuzz, Tyrannosaur, Peaky Blinders and The Suspicions of Mr Whicher.
Prince Daemon Targaryen – Played by Matt Smith
The younger brother to King Viserys and heir to the throne. A peerless warrior and a dragonrider, Daemon possesses the true blood of the dragon. But it is said that whenever a Targaryen is born, the gods toss a coin in the air.
“I hope me and Paddy found a lot of richness in their relationship”, said the former Doctor Who star. “Everything is about his brother for Daemon.”
Matt Smith is one of the most in-demand actors in the world after starring roles in Doctor Who, The Crown, Morbius and Last Night in Soho.
Young Princess Rhaenyra Targaryen – Played by Milly Alcock
She's the king’s first-born child, 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.
Austalian actress Milly Alcock has starred in dramas such as Janet King and Reckoning in her home country.
She also had a breakout performance in Tim Minchin's comedy Upright, which will return for season 2 soon.
The series is about struggling musician Lucky (Minchin) and the unlikely bond he forms with runaway teen Meg (Alcock).
Upright is streaming now on Sky Atlantic with NOW.
Alcock will be replaced in later episodes by Emma D'Arcy as the show time jumps forward several years.
Princess Rhaenyra Targaryen – Played by Emma D’Arcy
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.
"Rhaenyra is fuelled by that old Targaryen stuff," said D’Arcy.
"The journey over the course of the series is recognising when to let that fire burn and when to dampen it."
They admitted in an interview with The I that when they auditioned for the show, they believed it was a Game of Thrones spoof.
"Everyone’s making fantasy series these days, so I just thought it was some spoof version," they said.
"I didn’t realise until I was asked to send in another audition tape."

From House Arryn, Aemma marries into House Targaryen as Lord Viserys' wife and cousin. At the start of House of the Dragon, we hear about her struggles with Viserys to have a baby boy and heir to the Iron Throne.

Young Aegon Targaryen II - Plays by Ty Tennant

It's a bold performance from the young Tennant, who has to tackle an interesting scene at a windowsill. You'll know it when you've seen it.
Young Aegon is an unpleasant character, but appears happy to let Princess Rhaenyra take the Iron Throne. However, his mother Queen Alicent is determined to make sure he succeeds his father King Viserys,

Ser Criston Cole – Played by Fabien Frankel
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 honour and his preternatural skill with a sword.
Princess Rhaenyra Targaryen chose Ser Criston as her protector, despite protests from Otto Hightower. Rhaenyra believes his combat experience will come in handy if she ever finds herself in danger... she might be on to something.
Ser Criston becomes a pivotal character in season one, when he begins an affair with Rhaenyra. Despite the fact she initiated the romance, he is turned down by the Princess when he offers her the chance to run away with him.
He reacts terribly to her decision and continues to resent the Princess. As a result, he aligns closely with Queen Alicent.
Fabien Frankel has previously starred in rom com Last Christmas and as Dominique Renelleau in the BBC drama The Serpent.
Mysaria – Played by Sonoya Mizuno
She came to Westeros with nothing, was sold more times than she can recall, and she 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.
In episode 2, Mysaria came to the fore as Prince Daemon revealed plans to wed and start a family with his ally - causing quite the outcry.

Craghas was the leader of the Triarchy, which was the alliance of three of the Free Cities across the Narrow Sea - Lys, Myr, and Tyrosh.

Talking to Entertainment Tonight about how he wanted to acknowledge the great Lannister characters in Game of Thrones, Jefferson said fans could expect "tiny little drops of Tyrion or tiny little drops of Cersei".
