The series is expected in 2022, HBO programming chief Casey Bloys told select media outlets at the Television Critics Association winter press tour in January 2020. The network picked up the series, based on author George R.R. Martin’s A Song of Ice and Fire book series and its companion materials, WarnerMedia announced to investors in late October 2019.

House of the Dragon has been in development for several years (though the title has changed a couple of times during that process),” Martin wrote on his blog in response to news of the series pickup. “It was actually the first concept I pitched to HBO when we started talking about a successor show, way back in the summer of 2016.”


What It’s About

Set 300 years before the events of Game of Thrones, the series tells the story of a turbulent period for House Targaryen, one that set sibling against sibling and dragon against dragon. The point of contention: who should rule on the Iron Throne, of course.

“If you’d like to know a bit more of what the show will be about… well, I can’t actually spill those beans,” Martin teased in his blog, “but you might want to pick up a copy of two anthologies I did with Gardner Dozois, Dangerous Women and Rogues, and then move on to Archmaester Gyldayn’s history, Fire & Blood.”

Dangerous Women includes what press materials describe as a “35,000-word novella” by Martin called “The Princess and the Queen, or, the Blacks and the Greens,” which is “about the Dance of the Dragons, the vast civil war that tore Westeros apart nearly two centuries before the events of A Game of Thrones.”

Rogues, meanwhile, includes Martin’s story “The Rogue Prince, or, a King’s Brother,” which chronicles “the early life, adventures, misdeeds, and marriages of Prince Daemon Targaryen,” considered “one of the biggest rogues in the entire history of Ice and Fire.”

Finally, the novel Fire & Blood, released in November 2018, is the first novel of a two-part history of the Targaryens in Westeros.

“Centuries before the events of A Game of Thrones, House Targaryen — the only family of dragonlords to survive the Doom of Valyria — took up residence on Dragonstone,” according to the book’s description on the author’s site. “Fire & Blood begins their tale with the legendary Aegon the Conqueror, creator of the Iron Throne, and goes on to recount the generations of Targaryens who fought to hold that iconic seat, all the way up to the civil war that nearly tore their dynasty apart.”

Martin and Condal serve as co-creators of the series, while Emmy-winning director Sapochnik and Condal will be showrunners and executive producers. Martin, Vince Gerardis, Sara Lee Hess, and Ron Schmidt are also executive producers. Sapochnik will direct the pilot and additional episodes of the series, which Condal will write.

Sapochnik won the 2016 Primetime Emmy award for Outstanding Directing for a Drama Series for Game of Thrones episode “Battle of the Bastards” and shared the 2019 Outstanding Drama Series Emmy award with Martin, Gerardis, series creators David Benioff and D.B. Weiss, and other producers on the final season.

Clare Kilner (The Alienist: Angel of Darkness) and Geeta V. Patel (The Witcher) will also direct the series. Greg Yaitanes (Banshee) will also direct and is also a co-executive producer.

Martin introduced more series’ contributors in a blog post, noting Wes Tooke (Colony), Claire Kiechel (The OA), and Ti Mikkel, a writer’s assistant for Martin’s Fevre River Packet Company.

“Even Aegon the Dragon couldn’t conquer the Seven Kingdoms all by himself,” Martin wrote. “He needed the help of his sisters Rhaenys and Visenya. Ryan and I had some great assistance as well, and I wanted to give a tip of the crown to three talented and hard-working young writers who helped to bring this one home. ”

Game of Thrones announced on social media on February 2 that original series’ composer Ramin Djawadi will compose the score for House of the Dragon.

Djawadi talked to Rotten Tomatoes about composing for TV: “Main titles seems to be coming back…with Westworld and Game of Thrones, it’s a minute 45. That’s a dream for any composer to have that long in the beginning to set up a show. When I write my main themes, I still treat it like — I remember when I was a kid, and I want the main title to drag you into the room. When the show comes on, when the melody comes on, you go, ‘OK, my show is on, I have to come in now and watch.’”

Casting reportedly began in July 2020, and HBO describes Considine, Cooke, D’Arcy, and Smith’s roles as follows:

“Paddy Considine as King Viserys Targaryen. 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.

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 (pictured) 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.

Matt Smith (pictured) as Prince Daemon Targaryen. The younger brother of King Viserys and heir to the throne, Daemon is a peerless warrior and a dragonrider who 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…”

In February, HBO announced additional stars (pictured in order above):

“Rhys Ifans as Otto Hightower, the Hand of the King, who 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.

Eve Best as 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.

Sonoya Mizuno as 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.

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

And in April, Martin announced on his blog the casting of another character:

Fabien Frankel as Ser Criston Cole, who Martin describes as: “He is the common-born son of the steward to the Lord of Blackhaven. He has no claim to lands or titles, all he has is his honor and his skill with sword and lance. He is a challenger, a champion, cheered by the commons, beloved of the ladies. He is a lover (or is he?), a seducer (or is he?), a betrayer (or is he?), a breaker of hearts and a maker of kings.”

Release Date

A video teaser for HBO Max confirmed in December that House of the Dragon will be released in 2022. The teaser shows only a dragon roaring fire and a new glittering gold logo. But what a dragon!


SPOILER ALERT: WHILE INFORMATION THAT FOLLOWS WILL BE FAMILIAR TO FANS OF THE SONG OF ICE AND FIRE NOVELS AND THEIR COMPANION MATERIALS, INCLUDING FIRE & BLOOD, SOME OF IT MAY BE CONSIDERED SPOILERS TO ANYONE WHO HAS NOT READ THE BOOK SERIES.

For those who’ve read the books, the following is a refresher on some of the names, places, and conflicts in the source material. We won’t spoil some of the deaths with too much detail, but if you want that information, you can find more at A Wiki of Ice and Fire.


When It Takes Place

The Targaryens landed on Dragonstone more than four centuries before the events of the original Game of Thrones series. The Dance of the Dragons was a war of succession fought from 129 to 131 AC — that is, after Aegon I’s conquest of Wasteros.


What’s the Big Conflict?

The Targaryen civil war was a conflict over primogeniture, the system of inheritance by a firstborn child; often, the first-born son. A lord’s first child will inherit the castle and lands of his or her father over an older sibling no matter what his or her aptitude for governance compared to a sibling’s abilities. The Targaryens generally followed primogeniture, though there were exceptions, as during the rule of King Jaehaerys I.

When King Jaehaerys I’s eldest son, Prince Aemon, died, he left a daughter, Rhaenys. King Jaehaerys I then chose his next eldest son, Prince Baelon, to be new Prince of Dragonstone and heir to the throne rather than bestowing the honor on his granddaughter, a move that even Queen Alysanne disapproved of. When Baelon died unexpectedly — as well as Queen Alysanne and one of their daughters — grief-stricken Jaehaerys convened the Great Council to vote on succession, and the council chose Baelon’s son Viserys instead of Rhaenys’ son Laenor.

During his reign, Viserys had named Rhaenyra, his daughter by his first wife, as his heir, but upon Viserys’ death, his eldest son, Aegon, by his second wife instead ascended the throne, causing a great rift in the kingdom. By this time, Rhaenyra was also married to her uncle, the “rogue prince” Daemon Targaryen who had long sought the throne himself.

Fire & Blood recounts the battles between the siblings, their spouses, their offspring, their loyal followers, and, most viciously, the Targaryen dragons.


Who Are the Characters?

*confirmed

King Viserys I (103–129 AC)* – his death in early 129 began a great struggle of succession between his eldest child Rhaenyra and his first-born son, Aegon. Viserys’ dragon was especially notable: Balerion, the Black Dread, who King Aegon I Targaryen rode back during the Conquest of Westeros. Born in Valyria, Balerion was the last living dragon to have seen the Freehold, which the Targaryens left 12 years before the Doom. He was black-scaled with black wings and even black fire, which burned so hot that it melted the stone towers of Harrenhal (you saw the ruins in Game of Thrones when Arya Stark served as cupbearer to Tywin Lannister). Balerion died at around 200 years old in 94 AC, less than a year after Prince Viserys claimed him and while the prince was still very young; therefore, it is unlikely that House of the Dragon will show Balerion alive, unless the writers change the story or in flashback.

Alicent Hightower* – Viserys I’s second wife whose followers who would see Aegon crowned and were called “the greens” after a green gown the queen wore during a great tourney in which Rhaenyra wore traditional Targaryen black and red.

Daemon Targaryen* – Viserys I’s brother, Daemon was mad, bad, and dangerous to know — a skilled warrior and a denizen of disreputable Flea Bottom establishments. Rumored to have taken his teenage niece Rhaenyra’s virginity, he was sent into exile by Viserys. Years later, he would marry Rhaenyra, and upon the death of Viserys, he crowned his own wife, which touched off the bloody civil war known as the Dance of the Dragons. Dragon: lean, but fearsome red Caraxes, also called “the Blood Wyrm.”

Rhaenyra* – Viserys I’s daughter and first-born child by Aemma Arryn, Viserys I’s first wife who died in childbirth with her second child, a son, who also died. Rhaenyra was beautiful and beloved by her father and the people and was nicknamed “the Realm’s Delight” when she was young. As she grew older, she grew headstrong and competed with her ambitious stepmother Alicent. Her followers were called “the blacks” because of the gown the princess wore on the king and queen’s fifth anniversary tournament. Dragon: young yellow-scaled Syrax.

Ser Laenor Velaryon – Married his reluctant cousin Rhaenyra, who remarked to her father, “My half-brothers would be more to his taste.” Dragon: Seasmoke.

Rhaenys Targaryen and Lord Corlys Velaryon* – Parents of Laenor Velaryon. She was known as The Queen Who Never Was, because she was passed over as heir to the throne in favor of her uncle. Corlys was known as “The Sea Snake,” because of his prowess at sea.

Harwin Strong (aka “Breakbones”) – son of Lord Lyonel Strong and heir to Harrenhal, he was Rhaenyra’s lover while she was married to Laenor.

Ser Criston Cole* – A member of the Kingsguard, he became embroiled in the Targaryen civil war by switching allegiances from Rhaenyra, for whom he was once sworn shield (and perhaps loved), to Queen Alicent Hightower and her offspring.

Princes Jacaerys “Jace,” Lucerys “Luke,” and Joffrey “Joff” Velaryon – Rhaenyra and Laenor’s children, though rumored to have been fathered by Strong because they had dark hair like Strong, while cousins Laenor and Rhaenyra both had the Targaryen light silver/gold hair. The boys’ dragons were, respectively: Vermax, Arrax, and Tyraxes.

King Aegon II (129–131 AC) – Viserys I’s eldest son by Alicent, married his sister. Dragon: Sunfyre, “the Golden.”

Helaena – Aegon II’s sister-wife, had three children with Aegon. Dragon: Dreamfyre.

Twins Jaehaera and Jaehaerys and their younger brother Maelor – the offspring of Aegon II and Helaena.

Blood and Cheese – hired killers who murdered Jaehaerys in front of his mother, sparking her descent into madness.

Mysaria* – a prostitute who served as Daemon’s mistress of whisperers in Flea Bottom. The prince impregnated her, but she lost the child during a voyage to Lys to escape Viserys I’s anger over Daemon’s attempts to give the child a dragon egg, per Targaryen custom.

Aegon III (131–157 AC) – the son of Daemon and Rhaenyra Targaryen, he ruled after his uncle Aegon II, and at a very young age, married his cousin Jaehaera, who died young. His rule marked the end of the Dance of Dragons. He had five children by his second wife, Daenaera Velaryon. As a child, he grew melancholy after escaping a naval attack by mounting his dragon, but leaving his brother Viserys behind and believing that he had died. The brothers reunited later in life. Dragon: Stormcloud.

Mushroom – a fool in the courts of Viserys I Targaryen, Aegon II Targaryen, Rhaenyra Targaryen, and Aegon III Targaryen. His accounts of his days at court teemed with tales of debauchery and scandal.

Dragonseeds – Nettles, Hugh the Hammer, and Ulf the White were purportedly bastard Targaryen offspring. They each claimed dragons and fought for Rhaenyra, though Hugh and Ulf later switched allegiance.

Prince Qoren Martell – Dornish ruler who supported the Triarchy (an alliance of the Free Cities of Myr, Lys, and Tyrosh) in a war for the Stepstones against Prince Daemon Targaryen and Lord Corlys Velaryon.


Locations We’re Likely to See

Much of the drama takes place in King’s Landing and Dragonstone, but the fighting and bloodshed primarily happens in the Riverlands (led by House Tully at Riverrun). Many of the bloodiest battles occur around Harrenhal and The God’s Eye.

  • King’s Landing – the capitol
  • Dragonstone – House Targaryen’s family home
  • Driftmark – House Velaryon’s family home
  • Dorne – The southernmost kingdom in Westeros, it was not under Targaryen rule during the Dance of the Dragons.
  • Oldtown – kept safe the Targaryen riches during the Dance of the Dragons
  • Lys – one of the Free Cities of Essos; known for its brothels
  • The Stepstones – the broken land bridge between Dorne and Essos
  • Harrenhal – the massive fortress above Gods Eye melted by Balerion the Dread.
