Who’s Who in Westeros: A House of the Dragon Character Guide

Seven kingdoms, one Iron Throne, and a whole lot of people with odd names to keep track of: That was the formula for Game of Thrones. Now House of the Dragon, HBO’s blockbuster prequel to its most successful series of all time, is following suit.

The good news for fans of the world created by novelist George R.R. Martin is that Dragon features way fewer houses to keep track of; it tells the tale of a budding conflict and eventual civil war within the ruling family of House Targaryen itself. The bad news is that everyone is someone else’s aunt or uncle or brother or cousin or spouse — often more than one at once — and most of them share the same surname. It’s a lot for even a maester to keep track of.

But don’t worry! With the help of the show’s source material, Martin’s faux-historical novel Fire & Blood, we’ve got your quick-and-easy guide to all of Dragon’s major players. Sit back, relax, and keep up with the Targaryens.

This article contains spoilers up through the season-one finale.

The (disputed) King of Westeros and family, ensconced within the Red Keep

Queen Alicent Hightower (Emily Carey as a youth, Olivia Cooke as an adult)

Daughter of Otto Hightower, the once and future Hand of the King. Having lived in the Red Keep most of her life, she is a fixture at court, making her a natural companion for the young Princess Rhaenyra. Acting on the orders of her father Ser Otto, Alicent comforts King Viserys after the deaths of his wife and newborn, and under pressure to remarry, Viserys passes over a more politically advantageous union in favor of Alicent. Together the couple have two sons, Aegon and Aemond, and a daughter, Helaena. Their union alienates both Corlys Velaryon and Princess Rhaenyra while furthering the political ambitions of Ser Otto.

After learning from Ser Criston Cole that Rhaenyra lied about her “virtue,” Alicent turns on Rhaenyra, recruiting Cole to her side and rolling up to Rhaenyra’s wedding welcome feast in the green of House Hightower, rather than the black and red of House Targaryen. As the years pass, Alicent remains a steadfast foe of her former friend, constantly arguing that Rhaenyra’s children are bastards and that her son Aegon should be named heir to the Iron Throne.

At the funeral for Laena Velaryon, Alicent seizes Viserys’s legendary dagger and tries to stab out the eye of Rhaenyra’s son Lucerys after he stabs out the eye of her own son Aemond. Instead, she wounds Rhaenyra and disgraces herself before the assembled aristocracy. Her father the Hand, however, is proud of the fire she showed — and prouder still of Aemond for winning over the massive dragon Vhagar to their side.

Alicent is prepared to back Ser Vaemond Velaryon’s claim to the Driftwood Throne until Daemon Targaryen’s sword puts an end to the matter. At the royal gathering that follows, Alicent reconciles with her old friend Rhaenyra. But Alicent misinterprets the dying words of the senile Viserys to mean that her son Aegon is meant to unite the realm as king.

In the immediate aftermath of Viserys’s death, Alicent reluctantly joins the preexisting conspiracy, led by Otto, to crown Aegon II. She attempts to do so on terms that will be acceptable to Rhaenyra; she tasks Ser Criston Cole and her younger son, Aemond, with tracking down the missing Aegon before her father persuades him to order Rhaenyra’s execution. Successful, she sees Aegon crowned but also witnesses the escape on dragonback of Rhaenys Velaryon, whose support she’d hoped to gain.

In a last-ditch effort to keep the peace, Alicent extends generous terms of clemency to Rhaenyra, and has her father, Ser Otto, present her old friend with a torn-out page from a history book they’d studied together. She hopes this reminds Rhaenyra of their former closeness and continued love.
Alicent appears to suffer from severe anxiety that causes her to pick at her cuticles until she draws blood.

King Aegon II Targaryen (Ty Tennant as a youth, Tom Glynn-Carney as an adult)

King Viserys and Queen Alicent’s eldest child. When we meet him as a teenager, he’s into teenage-boy things, like pranking his younger siblings and jerking off. He seems reluctant to follow his mother’s advice and prepare for a life on the Iron Throne in place of his half-sister Rhaenyra. At Laena’s funeral, we learn that Aegon and his sister Helaena are betrothed and that Aegon is something of a drinker. By the time we see him again six years later, it’s clear he’s a habitual sex criminal.

On the night of the death of his father King Viserys, Aegon is MIA, out drinking and participating in lethal fight clubs involving literal children. He is captured and secured by Mysaria, the White Worm, and retrieved by Erryk and Arryk Cargyll, Kingsguard knights in service of his grandfather Otto Hightower. He is kidnapped once again by Ser Criston Cole and brought to his mother, who browbeats the reluctant prince into accepting his new role as king, granting him the iron crown of Aegon the Conqueror as well as the ancestral Valyrian steel blade Blackfyre. Just as he’s warming up to the idea, Rhaenys Targaryen rains on his parade by busting up the coronation ceremony with her dragon.

His dragon is Sunfyre the Golden.

Queen Helaena Targaryen (Evie Allen as a youth, Phia Saban as an adult)

King Viserys and Queen Alicent’s middle child. She seems more interested in hobbies like studying insects than matters of the royal court. Though Princess Rhaenyra proposed to Queen Alicent that Helaena marry her eldest child, Prince Jacaerys, the king and queen instead betroth Helaena to her elder brother, Aegon. When we meet her again six years later, she counsels her cousin Baela that her fiancé, Jacaerys, won’t demand too much of her sexually unless he’s drunk.

Helaena is prone to mysterious, prophetic utterances; she appears to have inadvertently predicted the loss of her brother Aemond’s eye and the escape of Rhaenys from beneath the floor of the Dragonpit.

Her dragon is named Dreamfyre.

Prince Aemond Targaryen (Leo Ashton as a youth, Ewan Mitchell as an adult)

King Viserys and Queen Alicent’s younger son. A target of bullying not only by Princess Rhaenyra’s children Jacaerys and Lucerys but also his own older brother, Aemond is relentlessly teased for his failure to bond with a dragon. He rectifies this in spectacular fashion by seizing the oldest, biggest dragon alive, Vhagar, at Laena Velaryon’s funeral. The resulting physical altercation between him and his cousins costs him an eye.

Six years later, an eye patch–wearing Aemond is taller, stronger, and a more formidable warrior than his older brother, Aegon. Taunted by his young nephews with a roast pig, a reference to the pig they once dressed as a dragon and dubbed “the Pink Dread” to mock him, he provokes a fight by not so subtly referencing the Velaryon boys’ “Strong” heritage, a reference to Rhaenyra’s rumored affair with Harwin Strong. Only a face-off with Daemon makes him back down.

Following the death of his father Viserys, Aemond aids Ser Criston Cole in the search for his brother Aegon. After Aegon II’s coronation, Aemond beats Lucerys Targaryen to Storm’s End, seat of House Baratheon. Aemond’s offer of a marriage pact between the two houses leads Lord Borros Baratheon to favor the Greens over the Blacks. He dismisses Luke, and Aemond follows the younger aboard his massive dragon, chasing Luke and his smaller steed through the storm clouds. A fight between the dragons that seems beyond Aemond’s control ensues, and Luke and his dragon are both killed by Vhagar.

Ser Otto Hightower (Rhys Ifans)

Viserys’s (and then Aegon II’s) Hand, a most powerful — and ambitious — adviser. Otto is a scion of House Hightower, one of the Seven Kingdoms’ richest families, and despite his influence at court, is still under pressure from his even more powerful older brother, Lord Hobert Hightower. When he reports tales of Rhaenyra and Daemon’s public dalliance to King Viserys, he is stripped of his office and ordered to return to Oldtown. On his way, he warns Alicent that a future Queen Rhaenyra will put Alicent’s children to death in order to secure her hold on the throne.

After Larys Strong kills his own father, Lyonel Strong (who replaced Otto as Hand), to curry favor with Alicent, Otto returns to his old job. Following the debacle at Laena’s funeral, he tells Alicent he’s proud of her for showing some moxie by attacking Rhaenyra on Aemond’s behalf.

After the death of Viserys, Otto’s long-laid plans to crown his grandson Aegon king in place of Rhaenyra take effect. Though he is unable to persuade Alicent and Aegon to order the execution of Rhaenyra and her children, he does see Aegon ascend the throne. The escape of Rhaenys, however, puts something of a damper on the proceedings.

Otto leads a diplomatic mission to Rhaenyra at Dragonstone, offering terms of clemency that would retain Aegon II as monarch. She does not acquiesce, but she also avoids making any immediate moves against the Greens.

Ser Criston Cole (Fabien Frankel)

One of the most formidable young knights in the Seven Kingdoms. Of Dornish descent (though he seems to have fought against the Dornish on behalf of the lord he serves), he is of common birth and has little power beyond the fast-rising fame he acquires via his prowess as a swordsman. He emerges as a major figure — and heartthrob — in the king’s tourney when he defeats Prince Daemon in hand-to-hand combat.

When a slot in the Kingsguard opens up, Cole is hand-selected by Princess Rhaenyra to join the order as her sworn shield. The two become friends, and he helps Rhaenyra defend herself when a wild boar attacks her during a hunt held in honor of her little brother.

When Rhaenyra is spurned by her uncle Daemon, she seduces Ser Criston, who is so smitten with the princess that he proposes they run away together. When she rejects this offer, he turns on her and beats the lover of her fiancé Laenor Velaryon to death. He also confesses his affair with Rhaenyra to Queen Alicent, who keeps his secret and thus spares his life. As time passes, he becomes the fiercest ally of Queen Alicent and her contingent, known as “the Greens,” and Rhaenyra’s most implacable enemy. Cole’s devotion to Alicent and hatred for Rhaenyra is so total that he nearly stabs out the eye of Rhaenyra’s son Lucerys on Alicent’s orders. He is thwarted by the king and Ser Harrold Westerling, then Lord Commander of the Kingsguard.

When King Viserys’s death is revealed to the Small Council, Cole bashes in the head of Lord Beesbury, who objects to the Council’s plan to crown Aegon II instead of Rhaenyra, drawing first blood in the conflict. Cole subsequently hunts down Aegon, who had gone missing, and personally sets the crown on the new king’s head.

Lord Larys Strong (Matthew Needham)

Nicknamed “the Clubfoot” after the deformity that’s left him with a limp, Larys is the son of influential Lord Lyonel Strong. He informs Alicent that Princess Rhaenyra received a dose of moon tea the night she was accused of fornicating with Prince Daemon, eventually leading to Ser Criston Cole’s confession of inappropriate relations with the princess. Having ingratiated himself with the queen, Larys acts on her desire that his father, Lord Lyonel, be replaced by her own father Ser Otto as Hand of the King. He has Lyonel and his own brother Harwin assassinated by arsonists, making him the new Lord of Harrenhal.

After King Viserys’s death, we learn how and why Larys relates his intel to Alicent: He trades information for glimpses of the queen’s feet. During one such exchange, he reveals the role of Daemon’s former lover Mysaria, the White Worm, in relaying information to Ser Otto. His minions set fire to Mysaria’s compound in hopes of killing her on Alicent’s behalf.

Larys is an enthusiastic torturer who personally cuts the tongues out of criminals’ mouths.

Ser Arryk Cargyll (Luke Tittensor)

One-half of a pair of twin brothers sworn to service in the Kingsguard, he is virtually indistinguishable from his twin brother, Ser Erryk. Arryk remains loyal to the Greens during the hunt for Aegon II, and is part of the Green contingent that travels to Dragonstone to offer Rhaenyra terms of surrender.

Grand Maester Orwyle (Kurt Egiyawan)

Chosen to be the successor of the late Grand Maester Mellos on Viserys’s Small Council, Orwyle’s medical methods are significantly more modern than his predecessor’s, though was not able to prevent the king’s declining health.

Orwyle appears to have been a part of Ser Otto’s conspiracy to crown Aegon II in Rhaenyra’s stead; he joins the mission to Dragonstone to broker a peace with Rhaenyra.

Lord Jasper Wylde (Paul Kennedy)

The successor to Lord Lyonel Strong as Master of Laws on the Small Council. Strong was promoted to Hand of the King after King Viserys banished Otto Hightower from court in the wake of allegations of fornication between Princess Rhaenyra and Prince Daemon. Wylde returned to Master of Laws after King Viserys re-appointed Otto as hand, and the two men have become allies on the Council. It falls to Wylde to explain to Queen Alicent that her father’s plan to name Aegon II heir in place of Rhaenyra was best maintained without her knowledge.

Ser Tyland Lannister (Jefferson Hall)

Tyland is the first member of the Small Council to admit that plans to crown Aegon II in Rhaenyra’s place have long been in effect. In Daemon’s eyes, Tyland’s long service with Ser Otto on the Small Council ensures House Lannister’s loyalty to the Greens.

Lord Jason Lannister (Jefferson Hall)

The young, rich, and obnoxious head of House Lannister and Lord of Casterly Rock. Jason desperately wants to marry Rhaenyra, even though he believes her half-brother, Aegon, should be crowned in her place. His open ambition alienates both Rhaenyra and Viserys.

Daemon assumes that, due to Jason’s brother Tyland’s close ties to Ser Otto Hightower, the Lannisters will back the Greens against the Blacks.

Lord Hobert Hightower (Stefan Rhodri)

Head of one of the oldest, richest, and most influential families in Westeros. As lord of the city of Oldtown, he exerts influence on both the maesters and the Faith, both of which are headquartered in the city.

Lord Borros Baratheon (Roger Evans)

Lord of Storm’s End and head of House Baratheon following the death of his father, Lord Boremund. Despite Boremond’s allegiance to Rhaenyra, the proud and illiterate Borros entertains the marriage offer presented to him by the Greens. While he will not permit the visiting Prince Aemond to stab out the eye of Prince Lucerys when both arrive to court his support, he does not stop Aemond from pursuing the younger boy on dragonback once Luke departs.

A.k.a. the One True Queen and her court, exiled to Dragonstone

Queen Rhaenyra I Targaryen (Milly Alcock as a youth, Emma D’Arcy as an adult)

King Viserys’s sole surviving child at the time the series starts. Known as “the Realm’s Delight,” Princess Rhaenyra is a popular figure among both the nobility and the smallfolk … or was, until Viserys and his new wife, Rhaenyra’s former friend Alicent Hightower, had a son, Prince Aegon.

Viserys named Rhaenyra heir to the throne over his unpredictable brother, Prince Daemon, despite the fact that she’s a woman. Viserys entrusts her with the secret of “The Song of Ice and Fire,” a prophetic dream in which the Targaryen dynasty’s founder, Aegon the Conqueror, foretold the conflict with the White Walkers that drove Game of Thrones.

After a wild night out with her estranged uncle Daemon that ends with the two nearly having sex in a brothel, Rhaenyra seeks the companionship of Ser Criston Cole, her sworn Kingsguard shield. Confronted about her deeds by the king, who received word of her adventures from Otto Hightower, she denies the charges and agrees to marry Laenor Velaryon in order to unite the Seven Kingdoms’ two major Valyrian houses. Despite working out an arrangement with her semi-closeted husband, she can’t account for her lover, Ser Criston, who beats Laenor’s boyfriend, Ser Joffrey Lonmouth, to death.

While married to Laenor, Rhaenyra gives birth to three sons: Jacaerys, Lucerys, and Joffrey. Their real father, fairly obviously, is Ser Harwin Strong, Prince Daemon’s successor as Lord Commander of the City Watch. When rumors of the children’s true parentage, spread in part by Queen Alicent and Ser Criston, make life in King’s Landing unbearable, the family retreats to the ancestral Targaryen fortress of Dragonstone. But when the extended families reunite to attend the funeral of Daemon’s wife, Laena Velaryon, all hell breaks loose. In a late-night fight among the children over Aemond Targaryen claiming Laena’s dragon Vhagar, Aemond loses an eye and the legitimacy of Rhaenyra’s children is questioned in front of the assembled court. Rhaenyra herself is wounded when Alicent tries to stab Lucerys out of vengeance. Amid all this, Rhaenyra and Daemon become sexually and romantically involved. Rhaenyra proposes to Daemon, and together they remove Laenor from the picture by faking his death.

Six years later, Rhaenyra returns to King’s Landing to defend her son Lucerys’s claim to the Driftwood Throne of House Velaryon. To garner support, Rhaenyra promises Rhaenys Targaryen, her cousin and the mistress of Driftmark, that she’ll betroth her sons Jacaerys and Lucerys to Rhaenys’s grandchildren Baela and Rhaena. After Viserys and Daemon settle the matter — by proclaiming Lucerys the heir and killing his rival claimant, Vaemond Velaryon — Rhaenyra attends a dinner for the royal family. Despite the conflict that breaks out between the younger generation, Rhaenyra reconciles with Alicent and escorts her children home to Dragonstone, with plans to return to King’s Landing as soon as she can. But Rhaenyra’s plan is thwarted when Alicent and her father crown Viserys’s son Aegon II as ruler of the Seven Kingdoms. The news causes Rhaenyra to miscarry her third child with Daemon.

Reluctant to start a civil war, both because of her knowledge of the Song of Ice and Fire and her lingering affection for Alicent, Rhaenyra dispatches her sons Jacaerys and Lucerys to visit various powerful lords to ensure their support. Luke is accidentally killed by Alicent’s son Prince Aemond and his dragon, Vhagar, triggering the conflict Rhaenyra sought to avoid.
Rhaenyra is bonded with a creature called Syrax.

Prince Daemon Targaryen (Matt Smith)

Viserys’s younger brother, a rogue prince who doesn’t much care what anyone thinks of him. As lord commander of the City Watch of King’s Landing, Daemon whipped the proto-police force into brutal military shape; it took the name “the Gold Cloaks” from the new uniforms he issued.

Banished from the capital for making light of the death of Viserys’s son, Daemon fled to the ancestral Targaryen fortress of Dragonstone with his paramour, the sex worker Mysaria. After a series of moves designed to provoke his brother failed to produce any political gains, Daemon forged an alliance with Lord Corlys Velaryon to wage war against the eastern alliance called the Triarchy and its admiral, the vicious Crabfeeder. The war dragged on for years until Daemon, spurning a long-delayed offer of aid from his brother, ended it, picking a fight with the Crabfeeder directly and chopping him in half with his Valyrian steel longsword, Dark Sister.

Returning to King’s Landing, Daemon reconciled with his brother, offering him the crown he won by conquering the Stepstones, but a risqué night out with his niece Rhaenyra caused Viserys to banish him once again. Daemon returned for her wedding celebrations after killing his wife, Lady Rhea Royce of the Vale, and flirted heavily with Lady Laena Velaryon, whom he subsequently married. Living abroad in the Free City of Pentos, Daemon and Laena had twin daughters, Rhaena (a dragon-rider bonded with a young beast called Moondancer) and Baela. Laena committed suicide-by-dragon while suffering from lethal complications during her third childbirth; unlike his brother Viserys, Daemon refused to order a fatal Cesarean section, allowing his wife to choose her own fate.

At Laena’s funeral, Daemon and Rhaenyra rekindled their romance from years earlier, getting Rhaenyra’s husband Laenor out of the picture by faking his death. (Daemon personally murders the man whose corpse they use in Laenor’s place.) He and Rhaenyra marry in a traditional Valyrian ceremony with their nervous children looking on and have two sons, Aegon (known as Aegon the Younger, in reference to his uncle, Alicent’s son Aegon) and Viserys (named after his grandfather the king). Daemon kills Vaemond Velaryon for questioning the legitimacy of Rhaenyra’s children Jacaerys, Lucerys, and Joffrey.

When news of Aegon II’s coronation reaches him, Daemon leads the charge in rallying support for Rhaenyra; when she proves to be more cautious than him, he assaults her. Having already distanced himself from Rhaenyra during the stillbirth of their third child, Daemon abandons the Black Council to seek more dragons to aid in the war effort. It is he who tells Rhaenyra that her son Lucerys has been killed by Prince Aemond.
Daemon’s dragon is a sinuous red beast called Caraxes.

Princess Rhaenys Targaryen (Eve Best)

Cousin to King Viserys and wife to Lord Corlys. Rhaenys was one of the two leading candidates for heir to Old King Jahaerys at the Great Council, but she was passed over in favor of her younger, male relative Viserys in order to maintain Westeros’s patriarchal tradition. This earned her the nickname “the Queen Who Never Was.”

An astute political observer, she is loyal to her legendary husband — who pushes for her to be named heir when the new succession crisis emerges — and rides a dragon called Meleys. She and Corlys have two children, a daughter named Laena, whom Corlys advances as potential queen for King Viserys, and Laenor, a son. Rhaenys is an enthusiastic backer of Laenor’s marriage to Rhaenyra, though she warns her daughter-in-law that the men of the realm would sooner burn the Iron Throne than seat a woman upon it.
When it becomes clear that Rhaenyra’s children are not Laenor’s, Rhaenys asks her husband to declare Baela, the elder daughter of the late Laena Velaryon, heir to the throne of Driftmark, the family stronghold. Corlys argues that this will only reinforce the damaging rumors about Rhaenyra’s sons, whom he still considers the best shot at preserving the Velaryon legacy despite their true paternity. Rhaenys also blames Daemon for Laena’s death; she claims the medical experts in Pentos failed where her own maester, Kelvyn, would have succeeded.

When Corlys is gravely wounded during the new war for control of the Stepstones, his brother Vaemond tries to persuade Rhaenys to support his claim to House Velaryon’s Driftwood Throne. Despite believing that Rhaenyra and Daemon conspired to kill her son Laenor, she instead backs the claim of Lucerys Targaryen, whom Rhaenyra has offered as husband to Rhaenys’s granddaughter Rhaena.

Following the death of King Viserys, Rhaenys’s support is courted by Queen Alicent, who acknowledges that Rhaenys would have made a better monarch than Viserys. Spirited out of the Red Keep by Ser Erryk Cargyll, Rhaenys breaks up the coronation of Alicent’s son Aegon II by escaping on Meleys. Rhaenys flies to Dragonstone and relates the news of Viserys’s death and Aegon II’s coronation to Rhaenyra. Impressed with the younger woman’s restraint over launching a civil war, Rhaenys successfully urges Corlys to back the Blacks against the Greens.

Lord Corlys Velaryon (Steve Toussaint)

Lord of the Tides, former adviser to King Viserys, and commander of the realm’s largest navy. Corlys Velaryon is the head of a great and noble house which, like the Targaryens, traces its ancestry directly to Valyria. The most skilled seafarer in the history of the Seven Kingdoms, he embarked on a series of famous journeys to distant lands dubbed the Nine Voyages, which earned him the nickname “the Sea Snake” (also the name of his flagship vessel) and made the Velaryons the richest house in Westeros. (Yes, even richer than the Lannisters.)

King Viserys refuses to aid the Sea Snake in his battles with the Triarchy — led by Craghas “The Crabfeeder” Drahar — for control of the Stepstones and rejects Corlys’s offer of marriage to his daughter Laena. So Corlys quits the Council and seeks a new alliance with Prince Daemon. Together, the two men defeat the Crabfeeder. In denial about his son’s homosexuality, Corlys brokers a union between House Velaryon and House Targaryen by agreeing to the betrothal of his son, Laenor to Princess Rhaenyra.

Some six years after his daughter’s funeral, he is gravely wounded in the latest war for control of the Stepstones. This leads to a succession crisis for control of House Velaryon, the Driftwood Throne, and the stronghold of Driftmark. Corlys’s brother, Ser Vaemond, ultimately loses the contest — and his head — in favor of Corlys’s nominal grandchild, Prince Lucerys Velaryon.

After recovering from his wounds, Corlys joins Rhaenyra’s cause at the urging of Rhaenys. He announces that he has won the war for the Stepstones, controls the Narrow Sea, and is prepared to blockade King’s Landing on Rhaenyra’s behalf.

Prince Jacaerys Velaryon (Leo Hart as a child, Harry Collett as a teen)

A.k.a. Jace. The eldest of Rhaenyra and Laenor’s three children. He is the first of the kids to realize his biological father is Harwin Strong.
In an attempt to reconcile with Queen Alicent’s side of the family, Princess Rhaenyra proposes marrying Jace to Alicent’s daughter Helaena; Helaena’s parents instead engage her to her brother Aegon. Jace participates in the vicious fight against Aemond after Aemond “steals” the dragon Vhagar.

Six years later, he is betrothed to Baela Targaryen in a last-ditch but successful effort by Rhaenyra to retain control of Driftmark on her family’s behalf. Following the news of Aegon II’s coronation, Jace’s mother entrusts him to relay her commands to Prince Daemon and the rest of her council when she goes into labor. It’s Jace’s idea to use dragons to rally the realm’s major houses to the Black’s cause; he is tasked with flying to the Eyrie and Winterfell on his dragon, Vermax, to recruit House Arryn and House Stark.

Prince Joffrey Velaryon

The youngest child of Rhaenyra Targaryen and, officially, Laenor Velaryon. Joffrey’s birth father, like that of his older brothers Jace and Luke, is actually Ser Harwyn Strong. He is named after Laenor’s slain lover, Ser Joffrey Lonmouth, and is bonded with a dragon named Tyraxes.

Lady Baela Targaryen (Shani Smethurst as a child, Bethany Antonia as a teen)

The older of Daemon Targaryen and Laena Velaryon’s twin daughters. Her grandmother Rhaenys wants her named heir to Driftmark, the Velaryon castle, because she’s of true Velaryon blood — unlike her cousin Jacaerys. Baela participates in the bloody fight against Prince Aemond over the dragon Vhagar, siding with her sister Rhaena and her cousins Jacaerys and Lucerys in the tussle.

Six years after her mother’s funeral, she is betrothed to Jacaerys Targaryen in a ploy to unite Rhaenyra’s branch of House Targaryen with House Velaryon. Following Viserys’s death and Aegon II’s coronation, Rhaenyra includes both Baela and her sister Rhaena in her strategy meetings, which seems to help earn the queen the respect of Rhaenys.

She is bonded with a dragon called Moondancer.

Lady Rhaena Targaryen (Eva Ossei-Gerning as a child, Phoebe Campbell as a teen)

The younger of Daemon and Laena’s twin daughters, Rhaena feels neglected by her father following her mother’s death.

Rhaena is dismayed to discover Aemond making off with Vhagar, Laena’s enormous dragon, after her funeral. The fight among the children that follows costs Aemond an eye and causes an irreparable rift between Alicent, Rhaenyra, and their respective allies.

Six years later, Rhaena is betrothed to Rhaenyra’s son Lucerys, heir to Driftmark and future Lord of the Tides, as part of the plan to unite Rhaenyra’s branch of House Targaryen with House Velaryon. Rhaenyra encourages Baela, like her sister Rhaena, to be a part of her war council after the coronation of Aegon II. The presently dragonless Baela, whose egg failed to hatch at her birth, seems particularly intrigued by Daemon’s description of all the dragons currently without riders.

Prince Aegon Targaryen the Younger

The first of Rhaenyra’s children with her uncle Daemon. He is named after the dynasty’s founder, Aegon the Conqueror, despite the fact that Alicent and Viserys had already named their own first son Aegon.

Prince Viserys Targaryen

Rhaenyra and Daemon’s second son. He is named after Rhaenyra’s father.

Ser Erryk Cargyll (Elliot Tittensor)

The other half of a pair of twin brothers in the Kingsguard, he is virtually indistinguishable from his brother, Ser Arryk. As Aegon II’s sworn protector, he is aware of the prince’s sinister proclivities and has no wish to see him crowned. He argues with his brother as they attempt to retrieve Aegon on Ser Otto’s behalf, then helps Princess Rhaenys with her escape from the Red Keep.

Though he is separated from Rhaenys as the people of King’s Landing are shepherded to the Dragonpit to witness Aegon II’s coronation, both manage to escape and make their way to Rhaenyra’s headquarters on Dragonstone. Ser Erryk brings her the golden crown of her father, King Viserys, and swears his fealty to her as part of her Queensguard.

Maester Gerardys (Phil Daniels)

A maester in service to Princess Rhaenyra. He helps instruct Prince Jacaerys in the High Valyrian language. Gerardys seems a likely candidate for Grand Maester should the Blacks succeed. He is a crucial and vocal component of Rhaenyra’s war council.

Ser Steffon Darklyn (Anthony Flanagan)

One of the Kingsguard knights assigned to protect Rhaenyra as princess. With some encouragement from Prince Daemon and his dragon Caraxes, Ser Steffon declares his loyalty to Rhaenyra and becomes part of her Queensguard.

Ser Lorent Marbrand (Maxim Wrottesley)

Like Ser Steffon, Ser Lorent is a Kingsguard knight assigned to Rhaenyra. He chooses to take her side in the conflict with the Greens.

Maester Kelvyn (Haqi Ali)

House Velaryon’s maester.He attends to the wound incurred by Aemond Targaryen during the fight with Lucerys Velaryon and the other children. He’s the person who informs Alicent that her son permanently lost his left eye.

Lord Bartimos Celtigar (Nicholas Jones)

Ruler of Claw Isle and close ally of House Targaryen.

Lord Bartimos stays loyal to Queen Rhaenyra in the split between the Blacks and Greens and becomes a vocal part of her council.

Lord Simon Staunton (Michael Elwyn)

Another of Queen Rhaenyra’s loyal bannermen. Staunton rules from a castle called Rook’s Rest in the Crownlands, the area surrounding King’s Landing. It is under direct control of the ruling monarch.

Those who remain unaffiliated, uncommitted, or otherwise uninterested in choosing a side.

Mysaria (Sonoya Mizuno)

A relative newcomer to the Seven Kingdoms who has lived the difficult life of a sex worker. One of the few characters on the show not directly descended from either Westeros or Valyria, Mysaria rises to become one of the star attractions at a chief King’s Landing “pleasure house.” She counts Prince Daemon Targaryen not just as a client but a confidante and becomes arguably his most trusted adviser. When he is banished by Viserys, she joins him in exile on Dragonstone. After learning that Daemon has (falsely) announced their marriage and pregnancy as a ploy to provoke his brother, she reprimands him for putting her at risk.

After returning to King’s Landing, Mysaria becomes a source of intelligence for Ser Otto Hightower using the nickname “the White Worm.” In the 16 years that follow, she remains a formidable spymaster in King’s Landing, counting even Queen Alicent’s own handmaidens among her informants. Mysaria quickly becomes aware of the death of King Viserys, which his close circle had hoped to keep secret, and kidnaps and transports Aegon II to a safe location before relaying his whereabouts to Sers Erryk and Arryk for a price. When her role is found out, Lord Larys Strong attempts to murder her via arson on behalf of Queen Alicent. Her fate is currently unknown.A relative newcomer to the Seven Kingdoms who has lived the difficult life of a sex worker. One of the few characters on the show not directly descended from either Westeros or Valyria, Mysaria rises to become one of the star attractions at a chief King’s Landing “pleasure house.” She counts Prince Daemon Targaryen not just as a client but a confidante and becomes arguably his most trusted adviser. When he is banished by Viserys, she joins him in exile on Dragonstone. After learning that Daemon has (falsely) announced their marriage and pregnancy as a ploy to provoke his brother, King Viserys, she reprimands him for putting her at risk.

Talya (Alexis Raben)

Queen Alicent’s handmaiden and an informant in Mysaria’s spy network, she is imprisoned along with many of the Red Keep’s other servants in order to keep Viserys’s death a secret until Aegon can be crowned. Larys Strong outs Talya as a spy to Alicent. Her current fate is unknown.

Ser Laenor Velaryon (Theo Nate as a youth, John Macmillan as an adult)

Son of Lord Corlys Velaryon and Princess Rhaenys Targaryen. Of Valyrian descent on both sides of his family, Laenor is a firm supporter of Daemon Targaryen during the war for the Stepstones and helps win the final battle atop his dragon, Seasmoke. After a wild night out with Daemon, Rhaenyra marries Laenor to please her father. The two nobles agree to maintain their respective extracurricular relationships, but Ser Criston Cole explodes at this arrangement and beats Laenor’s lover, Ser Joffrey Lonmouth, to death.

As the years pass, Laenor “fathers” Jacaerys, Lucerys, and Joffrey, but he is quite obviously not the boys’ biological father. Though he’s supportive of his wife, he seems to prefer the life of a sailor and soldier, as well as the company of Ser Qarl Correy, his most recent boyfriend.

Devastated by his sister Laena’s death, Laenor seeks comfort in Qarl’s arms and is thus absent from the fracas after the funeral. Feeling guilty that he wasn’t there to support his wife and sons, he rededicates himself to his marriage — just as Rhaenyra plots a new wedding to her uncle Daemon. Daemon murders a Velaryon servant and burns his face off, making it look like Laenor was killed and set ablaze by a jealous Qarl. In truth, Laenor shaves off his unmistakable white locks and escapes to Essos with Qarl in hopes of living a freer life.

Ser Qarl Correy (Arty Froushan)

Laenor Velaryon’s sparring partner, friend, and lover. Ser Correy accompanies Rhaenyra and Laenor’s family, at Rhaenyra’s own invitation, when they travel to Dragonstone to avoid the drama at King’s Landing. After the funeral for Laena Velaryon, Rhaenyra and Daemon engineer Qarl and Laenor’s escape from Westeros.

Ser Harrold Westerling (Graham McTavish)

A member of the Kingsguard, Ser Harrold serves as sworn shield and friend to Princess Rhaenyra, which he does in stalwart, loyal, and good-natured fashion. Ser Harrold takes over as the Kingsguard’s lord commander after the death of the order’s previous leader, Ser Ryam Redwyne.
At the disastrous funeral for Laena Targaryen, it falls to Ser Harrold to stand between Ser Criston Cole and Princess Rhaenyra’s children. Westerling quits the Kingsguard after being ordered to kill Rhaenyra and her children, vowing to return to service only when a new ruler is crowned.

Prince Reggio Haratis (Dean Nolan)

The largely ceremonial ruler of the Free City of Pentos on the western shore of the continent of Essos. Prince Reggio is the benefactor of Daemon and Laena during their stay in the city; he entreats Daemon to go to war on Pentos’s behalf against the rival alliance called the Triarchy.

Our season-one casualties.

Prince Lucerys Velaryon (Harvey Sadler as a child, Elliot Grihault as a teen)

A.k.a. Luke. Rhaenyra and Laenor’s middle child. Luke participated in the hazing of Aemond with his older brother Jace and Aemond’s elder brother, Aegon, and put out Aemond’s eye during the children’s fight at Laena’s funeral, leading Queen Alicent to call for one of his eyes to be put out as well. Both Ser Criston Cole and Alicent herself attempted to carry out this act but were thwarted.

Six years later, Luke was betrothed to Rhaena Targaryen in a successful effort to unite House Velaryon and Rhaenyra’s branch of House Targaryen. It was Luke’s prank on Prince Aemond that precipitated one last tussle among the younger generation. When Luke’s brother Jace was ordered to broker agreements with the Great Houses to Dragonstone’s north, Luke was dispatched on a shorter and ostensibly safer route to Storm’s End to ask for the aid of House Baratheon. He arrived to find Aemond already there, having successfully wooed Lord Borros Baratheon to the side of the Greens. When he took off on his small dragon, Arrax, he was pursued by Aemond aboard the massive beast Vhagar, who killed Luke and Arrax with a snap of its jaws.

King Viserys I Targaryen (Paddy Considine)

The First of His Name, King of the Andals and the Rhoynar and the First Men, Lord of the Seven Kingdoms and Protector of the Realm — the ruler of the continent of Westeros when the series begins. Selected as heir to the throne over his older female cousin, Rhaenys, after a dispute over the line of succession, this kind but weak monarch faced a similar crisis even as the Targaryen dynasty reached the height of its power. After losing his wife and newborn son and falling out with his younger brother, Daemon, Viserys named his sole surviving child, his teenage daughter Rhaenyra, the future queen of Westeros. His decision flew in the face of centuries of patrilineal tradition within House Targaryen and across the majority of the Seven Kingdoms, including the dispute that led to Viserys becoming king in the first place.

Encouraged by his advisers to remarry in order to strengthen his line, Viserys spurned 12-year-old Laena Velaryon, daughter of proud and powerful naval commander Lord Corlys Velaryon, in favor of his teenage confidante Alicent Hightower. Alicent gave birth to Viserys’s first surviving son (and potential male heir), Prince Aegon, as well as a baby girl, Princess Helaena, and a second son, Prince Aemond. Aegon’s birth complicated Viserys’s plans for Rhaenyra to succeed him; he was also tormented by a potentially prophetic dream about his son wearing the crown of Aegon the Conqueror, founder of the Targaryen dynasty.

Beset by pressures on all sides — complicated when Otto reported to him that Rhaenyra and Daemon were seen fornicating, for which Viserys fired Otto — Viserys banished Daemon a second time and ordered Rhaenyra to marry Laenor Velaryon, heir to the Driftwood Throne. The increasingly ailing king presided over a rushed wedding between Rhaenyra and Laenor after their lovers, Ser Criston Cole and Ser Joffrey Lonmouth, interrupted the celebrations with a lethal fight.

Ten years passed, during which Rhaenyra bore three sons; Viserys refused to hear any challenges to his grandsons’ legitimacy and insisted the two sides of the family and their supporters remain close despite obvious fractures, which widened before Viserys’s eyes at the funeral for Daemon’s wife, Laena Velaryon.

Six years after the funeral, the infectious wounds he incurred from the Iron Throne had cost him an arm, an eye, and any hope of living free of pain. Nevertheless, he adjudicated a dispute over which of his relatives should inherit the throne of House Velaryon — ultimately resolved when Daemon Targaryen sliced half of Vaemond Velaryon’s head off — and presided over a forced family dinner with all sides. The tension gave way to celebration until a fight between his children and grandchildren resumed the hostilities. That night, the ailing king confused his wife, Alicent, for his daughter Rhaenyra. His garbled words about “Aegon’s dream,” referring to the prophecy foretold by Aegon the Conqueror, convinced Alicent that their son Aegon is meant to rule the Seven Kingdoms, not Rhaenyra. He died later that night.

Lord Boremund Baratheon (Julian Jones)

The head of an important house of partial Valyrian descent. He accompanied Rhaenyra on part of her tour of the Seven Kingdoms in search of a suitable king consort. Lord Boremund died at some point prior to Viserys’s death and Aegon II’s coronation, leaving his proud and illiterate son Lord Borros in charge of House Baratheon.

Lord Allun Caswell (Paul Hickey)

The Lord of Bitterbridge in the Reach. Lord Caswell welcomed Princess Rhaenyra, her husband/uncle Prince Daemon, her three children from her first marriage, and her two with Daemon, home to King’s Landing. After Viserys’s death was revealed and the conspiracy to crown Aegon II took effect, Caswell was caught attempting to escape the Red Keep in order to warn her. He was hanged in the courtyard as a warning to others of dubious loyalty.

Lord Lyman Beesbury (Bill Paterson)

The aging Master of Coin on King Viserys’s Small Council. Not included in Ser Otto’s long-held scheme to crown Aegon II in Rhaenyra’s place, Beesbury was outraged to hear the idea put forth and announced plans to alert the princess. In response, Ser Criston Cole bashed in his head, killing him.

Ser Vaemond Velaryon (Wil Johnson)

The younger brother and close ally of Lord Corlys Velaryon, Vaemond participated in the war for the Stepstones, though he was dubious of the tactics embraced by the Velaryons’ ally in the conflict, Daemon Targaryen. His distaste for Daemon deepened following the death of his niece Laena, for which he appeared to blame the Prince.

When his brother Lord Corlys was gravely wounded during the most recent war in the Stepstones, Vaemond advanced his claim as heir to the Driftwood Throne, arguing — first implicitly, then explicitly — that Rhaenyra’s children with his nephew Laenor are bastards. For this, King Viserys demanded his tongue; Daemon sort of obliged by cutting off most of his head.The younger brother and close ally of Lord Corlys Velaryon. Vaemond participates in the war for the Stepstones, though he is dubious of the tactics embraced by the Velaryons’ ally in the conflict, Daemon Targaryen.

Lady Laena Velaryon (Nova Foueillis-Mosé as a child, Savannah Steyn as a teen, and Nanna Blondell as an adult)

Daughter of Lord Corlys Velaryon and Princess Rhaenys Targaryen. Her full-blooded Valyrian heritage and connection to her powerful parents led many on the Small Council to urge Viserys to marry her despite her young age. He rejected the proposal in favor of Alicent Hightower, infuriating Laena’s father.

During Rhaenyra and Laenor’s wedding celebration, Prince Daemon flirted heavily with Laena; the pair married, moved abroad, and had twin daughters, Rhaena and Baela. Laena died while giving birth to their third child, opting to order her massive and ancient dragon Vhagar to burn her to death rather than succumb to complications. Her funeral was a shitshow with massive ramifications for the future of the realm.

Lord Lyonel Strong (Gavin Spokes)

A member of King Viserys’s Small Council. Serving as Master of Laws, he was a forceful opponent of Rhaenyra’s claim to the throne, noting that it would break years of precedent and potentially destabilize the realm. He also scoffed at Lord Corlys’s suggestion of Rhaenys as a potential alternative. Later, however, he advised Viserys to marry Corlys’s young daughter, Laena, in order to bridge the gap between the two powerful Valyrian houses, advice Viserys ignored. He went on to urge the king to marry Rhaenyra to Laena’s brother Laenor, once again hoping to end the strife. In doing so, he deliberately rejected her possible marriage to his own son, a powerful knight named Ser Harwin Breakbones, which King Viserys had cynically assumed was Strong’s goal.

Lyonel seemed to be the only member of the Small Council whose advice did not directly benefit himself or his family, earning him the position of Hand of the King after Ser Otto Hightower’s dismissal. But it did not save him from scandal as his son Harwin not-so-secretly fathered Princess Rhaenyra’s three sons. After King Viserys refused his resignation, Lyonel asked permission to escort Harwin back to their home, the infamous castle of Harrenhal. There, they were killed by assassins deployed by Lyonel’s other son, Larys.

Ser Harwin Strong (Ryan Corr)

Son of Lord Lyonel and brother of Larys, Harwin was nicknamed “Breakbones” due to his incredible strength. He personally rescued Princess Rhaenyra from the chaos that broke out when Ser Criston Cole and Ser Joffrey Lonmouth fought during the welcome feast for Rhaenyra and Laenor’s wedding. He subsequently became her enthusiastic guardian and, uh, companion.

Harwin is the biological father of Rhaenyra’s children Jacaerys, Lucerys, and Joffrey, an inescapable fact that all at court except King Viserys seemed to acknowledge. After trying and failing to resign his post as Hand of the King over the scandal, Harwin’s father Lord Lyonel personally escorted Harwin back to Harrenhal, where they were both killed by Larys’ assassins.

Lady Rhea Royce (Rachel Redford)

Heir to one of the oldest and most powerful houses in the region called the Vale. Rhea was married to Daemon Targaryen, but the arranged marriage pleased neither party and was never consummated. After murdering Rhea to free himself from the marriage, Daemon claimed to be new heir to the Royce stronghold, Runestone, and its riches, but this is legally dubious due to the nature of their union.

Ser Joffrey Lonmouth (Solly McLeod)

A handsome young knight nicknamed “the Knight of Kisses” and romantically linked to Laenor Velaryon. After trying to forge a pact with Ser Criston Cole, he was beaten to death by the Kingsguard knight, leaving Laenor bereft.

Grand Maester Mellos (David Horovitch)

Scholar, healer, and member of King Viserys’s advisory Small Council. Mellos frequently found himself refereeing the power struggles between the other members of the Council and offering the king harsh advice when necessary. It’s Mellos who suggested the C-section that costs Queen Aemma her life. After the baby’s death, he firmly opposed the prospect of Daemon as heir. Mellos was one of the voices in favor of a marriage between Viserys and Laena Velaryon. He also oversaw the gruesome treatments for Viserys’s nonhealing wounds and offered Rhaenyra “moon tea,” a sort of Plan B pill, after her liaison with Daemon (alleged) and Ser Criston (real). Mellos died at some point during the show’s ten-year time jump.

Craghas “the Crabfeeder” Drahar (Daniel Scott-Smith)

The masked, heavily scarred admiral of a massive fleet assembled by the Triarchy, an alliance of three of the powerful Free Cities on the continent Essos. Earning his nickname from his penchant for feeding his wounded enemies to swarms of crabs, he commanded the string of islands called the Stepstones and dealt severe damage to the fleet and fortune of Lord Corlys Velaryon. An alliance between Corlys and Prince Daemon Targaryen put an end to the vicious naval commander, who was killed by Daemon in single combat.

Queen Aemma Arryn (Sian Brooke)

Viserys’s wife and Rhaenyra’s mother. A descendent of both House Arryn (the Lords of the Vale) and House Targaryen, she married her cousin Viserys in keeping with the Targaryen tradition of incestuous intermarriage to keep the royal bloodline pure. After enduring several difficult pregnancies that ended in tragedy, she died during a C-section ordered by Viserys and the royal physician Grand Maester Mellos in order to save the life of their unborn son. The child did not long survive his mother, and the events left Viserys devastated and the realm without a queen, until Alicent came along.

King Jaehaerys I Targaryen (Michael Carter)

Grandfather and predecessor to King Viserys. Known as both the Good King for his many works in improving the realm and the Old King for his eventual advanced age, he is considered the greatest monarch in the Targaryen dynasty with the possible exception of Aegon the Conqueror himself. No king ruled longer or had more of an effect on the lives and laws of the Seven Kingdoms. Faced with a difficult question of succession after the deaths of his sons, he convened the Great Council of Westeros lords to settle the matter in a vote held at the massive castle of Harrenhal. It was there that his grandson Viserys was selected over his granddaughter Rhaenys.

Though he appears in the premiere’s opening sequence, he is long dead by the time the core events of the series begin.
