Vaghar attacking Lucerys in House of the Dragon

Updated Oct 23, 2026, 11:41 PM EDT

House of the Dragon's fanbase has seen quite a bit of Vhagar, the oldest and strongest dragon alive in Westeros. She instills fear in her enemies and isn't above ignoring her rider when she sees fit (or simply disappearing for large periods of time). We've seen two riders claim her so far, but Vhagar has had quite a tumultuous history well before the Dance of the Dragons in the lore of the world. This old girl has earned her stripes and seen her share of warfare.

Visenya Rode Her Dragon Vhagar Into the Conquest

Vhagar hatched from her egg on Dragonstone 52 years before Aegon's Conquest. According to George R.R. Martin's novels, A Clash of Kings and A Storm of Swords, Vhagar was named after one of the gods of the Valyrian Freehold. Vhagar's early life was relatively uneventful, but a young Visenya Targaryen eventually claimed her as her mount. Visenya would go on to marry her brother Aegon Targaryen, who also married their sister Rhaenys. For years, House Targaryen was content to exist on Dragonstone. However, everything changed when the Storm King Argilac "the Arrogant" Durrandon sought to halt the advance of King Harren "the Black" Hoare, who was King of the Iron Islands and the Riverlands.

Someone powerful is acting dishonourably and everyone knows it. What do you do? In Westeros, the answer to this question has ended more than one great house.

ACall it out, openly and on the record. If honour means anything, it has to mean something when it's costly. BUse it. Information about someone else's dishonour is leverage — and leverage is power. CAct decisively to correct it — with or without the approval of those around me. DChallenge them directly. Strength settles disputes more honestly than courtroom manoeuvring. ENavigate carefully — build alliances, apply quiet pressure, and create a situation where the right outcome becomes inevitable.

NEXT QUESTION →

What is the source of your power? Every house endures because of something. What is it for yours?

AThe loyalty of people who trust me — earned over generations, not bought with gold. BWealth, intelligence, and the willingness to use both without sentiment. CA legacy so fearsome and a vision so total that opposition becomes unthinkable. DPhysical strength, military force, and the respect that comes from being the kind of person nobody wants to fight. ECharm, connection, and the ability to make powerful people feel that my success is also theirs.

NEXT QUESTION →

Who do you truly fight for? Strip away the banners and the words. The honest answer tells you everything.

AMy family and my people — those who depend on me and have kept faith with me through everything. BMy family — the ones who share my blood, even when they exhaust me, even when they disappoint me. CMy cause — a vision larger than any single person, including me. DMyself, and those few who've proven themselves worth fighting beside. EMy house — its name, its future, the position I intend to leave it in when I'm gone.

NEXT QUESTION →

How do you deal with your enemies? A house's method reveals its character as clearly as its words ever could.

AHonestly — I face them directly, and I give quarter when it's warranted. BThoroughly — I don't leave loose ends, and I don't make the same enemy twice. CDecisively — fire answers questions that diplomacy only delays. DHead-on — I'd rather meet a threat on the battlefield than behind closed doors. EElegantly — I prefer to make former enemies into allies, or at least into people who owe me something.

NEXT QUESTION →

What kind of ruler do you believe in? Westeros is full of answers to this question. Most of them end badly.

AA just one — someone who serves the realm rather than using it, who leads by example rather than fear. BA capable one — someone smart enough to navigate the game, ruthless enough to win it, and realistic about what winning costs. CA transformative one — someone who doesn't just rule what exists but reshapes what's possible. DA strong one — someone whose authority is beyond question because the alternative is obviously worse. EA wise one — someone who understands that the realm is fed by more than armies, and that a full stomach keeps more peace than a sharp sword.

NEXT QUESTION →

You suffer a devastating loss. How does your house respond? How a house handles defeat tells you more about it than how it handles victory.

AWe grieve, properly and together — and then we endure, because endurance is what we do. BWe adapt. We reassess. And we ensure that whoever caused this loss comes to regret it completely. CWe burn hotter. Setbacks don't soften us — they clarify what needs to happen next. DWe hit back. Grief and revenge are the same motion in our house. EWe regroup quietly, rebuild our position, and return when we're ready — on our terms, not theirs.

NEXT QUESTION →

Which of these truths about Westeros do you most believe? Every house has a philosophy. This is yours.

AThe lone wolf dies, but the pack survives. Nothing matters more than the people you protect. BA Lannister always pays their debts — in gold or in kind. Reputation is built on consistency. CI am the blood of the dragon. Some destinies are written before the person who carries them is born. DOurs is the fury. When we move, we move completely — and we don't stop until it's done. EGrowing strong means knowing when to bloom and when to wait. Patience is its own kind of power.

NEXT QUESTION →

The Iron Throne is within reach. What do you do? The answer reveals not just your ambition — but your character.

AClaim it only if the realm needs me to — and rule in a way that makes it worth having. BEnsure someone who owes us sits in it. The power behind the throne is safer than the throne itself. CTake it. It was always meant to be mine — I feel that in my bones and in my blood. DSeize it — with both hands, without hesitation. Opportunity in Westeros does not wait to be asked. EPosition my house to be indispensable to whoever sits there — influence outlasts any single reign.

The Maester Has Spoken Your House Is…

Your answers point to the great house whose words, values, and way of surviving in Westeros match your own. Bend the knee — or don't. That's very much up to you.

🐺 House Stark

Winter is Coming — and you have always known it. You prepare not out of fear but out of duty, because the people who depend on you deserve someone who takes the long view.

You lead with honour even when it costs you, because you understand that a reputation built on integrity is the only one worth having.
Your loyalty to family and people runs deep — not as sentiment but as a code that doesn't bend when things get difficult.
The North endures because Starks endure — not by being the cleverest players in the game, but by being the kind of people others are willing to follow into the cold.
You are that kind of person. The pack survives. The lone wolf dies. You already know which one you are.

🦁 House Lannister

You understand the game — its rules, its exceptions, and exactly when the rules become the exception. You play it without illusions and without apology.

You are sharper than most people realise, and you have learned to use that gap to your advantage.
A Lannister always pays their debts — and you always keep your word, because your word is an instrument of power, and instruments must be kept in working order.
You love your family with a ferocity that sometimes blinds you, and you know it, and you do it anyway.
The lion doesn't concern itself with the opinion of sheep. Neither, in the end, do you.

🐉 House Targaryen

You carry a sense of destiny that is difficult to explain and impossible to ignore — the feeling that you are not simply participating in the world but meant to reshape it.

You are capable of extraordinary things, and you know it, and that knowledge is both your greatest strength and your most dangerous quality.
Fire and blood are not just words to you — they are a philosophy about what change requires and what it costs.
The Targaryens at their best were transformative rulers who broke chains and defied the limits of what anyone thought possible.
At your best, so are you. The dragon has three heads. You are one of them.

🦌 House Baratheon

You are a force — direct, powerful, and difficult to ignore when you enter a room or a conflict. You do not negotiate with challenges. You meet them.

Ours is the fury — and yours is a kind of intensity that commands attention, respect, and occasionally fear from those who underestimate what's behind it.
You value strength and straight dealing. You'd rather know where you stand in a fight than navigate a web of courtly whispers.
The Baratheons built their house on the back of one of the greatest military victories in Westerosi history — and then struggled with what came after.
The lesson of your house is that winning is not the end of the story. Governing is. You are learning that too.

🌹 House Tyrell

You understand that power does not always announce itself — that sometimes it arrives with flowers, good wine, and a smile that doesn't quite reach the eyes.

Growing strong is your house's motto, and you live it: patiently, strategically, always investing in the relationships and resources that will matter most when it counts.
You are charming by choice and calculating by nature — a combination that makes you one of the most effective players in any room you enter.
The Tyrells fed King's Landing and shaped its politics without ever sitting on the Iron Throne — and they were arguably more powerful for it.
You know that the person who controls the food controls the kingdom. And you always know where the food is.

↻ RETAKE THE QUIZ

Harren had nearly completed construction on the dreaded fortress of Harrenhal, and King Argilac wanted to keep Harren from advancing into the Stormlands. Argilac sent the offer of an alliance to Aegon Targaryen. He offered his daughter Argella for Aegon to wed (Aegon had not married his sisters yet), but Aegon refused. Instead, Aegon asked that Argella marry his best friend (and allegedly his bastard brother) Orys Baratheon. When the emissary arrived in Storm's End, King Argilac had his hands cut off and sent back to Dragonstone, with a message stating, "These are the only hands you will receive." Aegon called his banners and set his eyes on the Seven Kingdoms in response. He sent ravens to the rulers of Westeros, stating that he would unify the Seven Kingdoms under House Targaryen. He began the campaign to dominate the Seven Kingdoms with his wives, forever being symbolized in House Targaryen's three-headed sigil alongside their dragons: Aegon atop Balerion, Rhaenys atop Meraxes, and Visenya atop Vhagar.

When Aegon landed at the mouth of the Blackwater Rush (a place that would later give rise to the Aegonfort and ultimately the city we know as King's Landing), Visenya spared no time and pressed the attack. She flew north to Castle Stokeworth, where the castle's soldiers and men-at-arms attempted to take down Vhagar with crossbow bolts. In response, Vhagar set the roof of Castle Stokeworth aflame, resulting in House Stokeworth's surrender. Seeing this, one by one, the lords of Westeros began to submit. Some resisted, while others laid down their arms and begged for mercy. After the fall of Houses Darklyn and Mooton, Aegon was crowned as King Aegon I Targaryen, First of His Name, King of All Westeros, and Shield of His People, and his new royal dynasty would last for nearly three centuries.

Visenya Targaryen Took Vhagar Into War Even After Aegon's Crowning

Visenya pressed onward and took Vhagar to accompany the Targaryen fleet to Gulltown. The fleet was attacked by House Arryn's fleet, which successfully destroyed a third of House Targaryen's ships. Visenya countered with Vhagar, torching the Arryn fleet in totality. Visenya then headed to Crackclaw Point to hear more pledges of loyalty before flying to Stoney Sept to regroup with Aegon and Rhaenys. They flew to the northern portions of the Reach, where the combined forces of Casterly Rock and Highgarden were five times as large as those of the Targaryen forces. But soldiers are no match for dragons; Balerion, Meraxes, and Vhagar took flight together and descended on the enemy troops.

As men battled on foot, the dragons melted thousands of men in their own armor. The dry grass on the battlefield that day caught fire and spread quickly, killing House Lannister and Gardener's forces in droves. At the end of the battle that would be known as the "Field of Fire," House Gardener was completely obliterated; thousands died from swords, arrows, and spears, while the dragons killed thousands more. Visenya herself took an arrow to the shoulder but would recover. Loren Lannister relinquished his crown the next day, earning the name "Loren the Last," but retained the title as Warden of the West. Aegon then gave dominion over Highgarden and the Reach to Lord Harlen Tyrell, House Gardener's steward.

The war raged on, and Visenya and Vhagar would eventually fly to the Riverlands, expecting to face King Torrhen Stark and his army of battle-hardened Northmen. The King in the North had heard the news of the Field of Fire and decided that defeating the Targaryens wasn't achievable. The King in the North wisely sent his brother to negotiate. The young conqueror would allow Torrhen Stark to keep Winterfell and his lordship over the North, but he would be a king no longer. Torrhen bent the knee before Aegon, earning him the name "The King Who Knelt." Vhagar's subsequent action during the War of Conquest was to fly to the Vale, landing in the courtyard of the Eyrie. Queen Regent Sharra Arryn ran out into the courtyard to find her son, King Ronnel Arryn of Mountain and Vale, resting on Visenya's knee and admiring Vhagar. The boy king requested that his mother allow Visenya to give him a ride on Vhagar's back. The Queen Regent bent the knee, resigning House Arryn's kingship. After Ronnel Arryn rode with Visenya and Vhagar three times around the mountain known as the Giant's Lance, House Arryn pledged fealty as Wardens of the East.

The First Dornish War and the Death of Queen Visenya

At the end of the initial war, six of the Seven Kingdoms had pledged fealty to House Targaryen. Balerion's dragonfire forged the Iron Throne, and Aegon and his queens ruled from King's Landing. Unfortunately, Rhaenys and Meraxes died during their invasion of Dorne, with defenders killing Meraxes with a scorpion bolt to the eye. The dragon's crash to earth was horrific, and Rhaenys' body was never recovered. Aegon and Visenya responded to the death of their sister by redoubling their efforts to conquer Dorne. During two years that would be known as the "Dragon's Wroth," Aegon and Visenya scoured all of Dorne, burning countless castles to the ground. Only Sunspear was spared from dragonfire, though it's unclear as to why this happened. Some Dornishmen rumored that Princess Meria Martell had bought a device that could slay the dragons, but Archmaester Timotty of The Citadel surmised that Aegon and Visenya wanted to force the Dornish houses into an uprising against House Martell. Despite the acts of Aegon and Visenya, Dorne remained defiant to the crown for many years. Although only six kingdoms remained united, the Conquest was deemed complete, and it would profoundly influence the politics of the continent for the next three centuries.

King Aegon ruled Westeros until 37 years after the conquest when he died from a stroke at age 64. He was cremated on Dragonstone, with Vhagar supplying the fire. Aegon's son Aenys became king and angered Visenya by naming his son (also named Aegon) the heir to the Iron Throne. The Faith of the Seven soon rose against Aenys due to House Targaryen's practice of incestuous marriage. When King Aenys died, Visenya flew to Pentos to retrieve her son Maegor from exile. With Maegor riding Balerion and Visenya on Vhagar, the two returned to King's Landing, which broke out in riots as they approached. Maegor killed the young Aegon and usurped his brother before setting Balerion loose on the Faith Militant. Visenya also took Vhagar across Westeros to tamp down any rebellion, with Vhagar burning down the strongholds of five houses in the Riverlands in a single night. Maegor's reign of cruelty would continue, but Visenya would die in 44 AC (After Conquest), leaving Vhagar without a rider. After going for decades without war or even a rider, the two surviving original dragons had largely become relics in an era full of much younger beasts, though Vhagar still had one last major role to play in the wars to come.

Baelon the Brave and Vhagar's Final Riders

Maegor the Cruel died unexpectedly atop the Iron Throne in 48 AC, leaving his nephew, Jaehaerys I Targaryen, as the heir to the Iron Throne. The young king would go on to be known as "The Conciliator," ushering in the longest period of prosperity in the history of Targaryen rule. After 29 years, Vhagar was then claimed by Jaehaerys's son, Prince Baelon "the Brave" Targaryen, who earned his name from whacking Balerion on the snout as a child. Baelon would ride Vhagar during the Fourth Dornish War, where he, his brother Aemon, and King Jaehaerys annihilated a Dornish fleet aiming to attack the Stormlands. Balerion the Black Dread would die of old age in 94 AC, leaving Vhagar as the lone surviving dragon who had participated in the War of Conquest. Unfortunately for her, Prince Baelon would soon die in 101 AC of appendicitis, leaving her riderless again.

During the reign of Viserys I Targaryen (Paddy Considine), Lady Laena Velaryon of Driftmark (Nanna Blondell) would become a dragonrider and claim Vhagar. Laena absolutely adored Vhagar, and she and Prince Daemon Targaryen (Matt Smith) toured the Free Cities together while Daemon was in self-exile, putting on spectacles on dragonback. However, when Laena was pregnant with her third child, she dreamed of returning home to Driftmark to give birth. Sadly, Laena went into labor in Pentos. After several excruciating hours, Laena and Daemon's child would not arrive, and Daemon was faced with the same horrible decision as his brother years earlier: Perform a dangerous procedure to save the child or lose both Laena and the baby.

Before Daemon made a decision, Laena rose from her birthing bed and made her way down to a nearby shore where Vhagar rested. She cried out in pain, begging to die on her own terms with her bodily autonomy intact. Though the dragon seemed initially reticent, Vhagar finally obeyed and burned Lady Laena alive in full sight of Daemon. During Laena's funeral on Driftmark, a young Prince Aemond Targaryen (Leo Ashton) ran out to Vhagar and climbed onto her back in the dead of night. After taking to the skies, Aemond returned to the castle and was confronted by Laena's daughters Baela (Shani Smethurst) and Rhaena (Eva Ossei-Gerning), outraged by Aemond claiming their mother's dragon when Rhaena did not have one of her own. A scuffle broke out, and Prince Lucerys "Luke" Velaryon (Harvey Sadler) sliced Aemond's eye with a knife. However, Aemond saw it as a fair exchange, as he "lost an eye but gained a dragon."

Vhagar's Played a Major Role in the Start of the Dance of Dragons

After the death of King Viserys, the Targaryen war of succession begins brewing. Queen Alicent Hightower (Olivia Cooke) and her father Ser Otto Hightower (Rhys Ifans), the Hand of the King, crown Viserys' son Aegon II (Tom Glynn-Carney) on the Iron Throne, flying in the face of Viserys naming his daughter, Rhaenyra (Emma D'Arcy), as his heir. Rhaenyra and Alicent both attempt to resolve things amicably, but Rhaenyra nonetheless sends her sons to treat with the Great Houses. Luke (Elliot Grihault) is tasked with riding his dragon Arrax to Storm's End to receive the support of Lord Borros Baratheon (Roger Evans). As he touches down in the courtyard, Luke notices Vhagar in the distance, knowing Aemond (Ewan Mitchell) must have beaten him to Storm's End. Upon meeting Lord Borros, the Storm Lord spurns his request for assistance, stating that the boy showed up empty-handed. Aemond taunts Luke, wanting revenge for the loss of his eye, but Luke is protected by Guest Right and Aemond must show restraint, allowing Luke to return to the courtyard to ride Arrax back to Dragonstone.

Flying over the waters of Shipbreaker Bay, Luke spots Aemond chasing after him on Vhagar. As Aemond taunts him, Luke and Arrax attempt to escape by flying through crags in the sea where Vhagar is too large to follow. The two young dragonriders struggle to control their dragons during the storm and during the chase. Vhagar doesn't listen to Aemond's commands and soars upwards through the storm-ridden clouds to kill Arrax with a single chomp, leaving the few remaining bits of him and Prince Luke falling into the sea. Aemond stares on in horror, as he knows this act not only makes him a kinslayer but will eventually be the spark for the civil war.

In the Dance of the Dragons, Vhagar Is the Greens' Most Powerful Weapon

With war fully raging between the Blacks and the Greens, each side needs to find every dragon they can get to have any hope of victory. Although both sides manage to stay restrained during the opening salvo, the shadow of Vhagar looms large over them. During the few days between the death of Lucerys and his funeral, Daemon remarks to Rhaenys that the power of Vhagar is the only reason the Blacks cannot simply overwhelm King’s Landing by force alone, as their side has far more dragons who are larger and more experienced in combat. But Vhagar is strong enough to serve as a serious deterrent to any escalation of the war, at least initially.

While revenge is the primary factor, the Blood and Cheese plot can arguably be attributed to sheer pragmatism for this very reason. Had Aemond been killed, as the plan called for, finding Vhagar another rider would have taken weeks or months at the very least, and the jury's out on whether that rider could even control the old dragon, allowing Rhaenyra to claim a swift victory during such a window and with little violence. As an asset to the Greens, Vhagar remains their biggest advantage. While not quite as old or as large as Balerion, she is still only a few decades younger than the Doom of Valyria, and the egg from which she hatched could predate the event, which might easily explain her huge size in comparison to the many other dragons who followed. As the last dragon still alive since the era of the Conquest, Vhagar remains by far the most experienced and resilient, making her a deadly threat for anyone who might ever dare to attack her.

Rook’s Rest Shows Vhagar Is Still a Dangerous Fighter

As the war rages, battles between dragons soon become inevitable, but it is only Aemond who realizes the importance of combining their power with regular armies of men. When Vhagar finally makes her grand entrance, the sheer scale of her advantage becomes clear for the first time in the war. Whereas Arrax was still relatively young, Meleys and Sunfyre are both bigger and older dragons (with Meleys' first rider being Viserys and Daemon's mother, Alyssa), but they are still outmatched by Vhagar in size and power. In a brilliant change from the books, Aemond decides to take advantage of the chance presented to him and attacks his brother while on dragonback himself. It only takes one precise blast of fire to bring Sunfyre down along with her rider.

Despite her own size and experience, Meleys might have a more experienced rider and could have been a fair match, but Vhagar is still much larger than her. Ultimately, Vhagar kills Meleys during the battle, robbing the Blacks of one of their most important dragons. It's clear to the Blacks that should they ever hope to win the war, killing Vhagar and her rider is now their main goal, forcing them to take creative and desperate measures to overcome this as they recruit civilians known as Dragonseeds to come and claim unclaimed dragons on Dragonstone.

Thankfully for them, the battle at Rook’s Rest also hints at Vhagar's key weakness. Because of her size, she is also quite slow, and there are several points in the battle where she finds herself outmaneuvered by Meleys and Rhaenys. With a rider experienced enough, the same ambush tactics used by Rhaenys could be used to great effect. Granted, the strength behind her jaw, fire, and claws would place the opponent directly in the line of fire and could still prove fatal for the attacking dragon and its rider. On the side of the Blacks, few Targaryens or dragons remain as powerful or as dangerous to take on such a deadly challenge, but Daemon seems determined to bring his nephew down.

As of the end of Season 3, Vhagar has gone missing. After flying to Harrenhal to take the keep, Aemond is stabbed and wounded by one of the Strongs. With Daemon gone from Harrenhal, Aemond is left to Alys Waters (Gayle Rankin), who nurses him back to health. When he wakes up, his dragon is no longer close by. Because of her size, Vhagar remaining at Harrenhal would make the castle a target of the multiple assassins sent to kill Aemond. The last we hear of her is that Vhagar is rampaging over the Riverlands. Book readers know that there's still one major battle for Vhagar to fight, and we will likely see her again in Season 4 for her showdown near the end of the war.
