Among the lowborn bastards swept into the fire and fury of the Targaryen civil war, the story of Addam of Hull Seasmoke stands out as a beacon of honor. While the Sowing of the Seeds elevated self-serving opportunists who betrayed their oaths for titles and gold, Addam of Hull chose a different path. Armed with courage and unbroken fidelity, he became one of the most heroic figures in the Dance of the Dragons.
The television adaptation of House of the Dragon has brought Driftmark’s lowborn brothers into the spotlight. As established in our character breakdown of Black Aly Blackwood, the later stages of the war introduce figures whose moral compass defies the corruption of the royal court. Addam does not fight for petty power; he rides into battle to prove the honor of his blood.
Here is the complete canonical story of Addam of Hull, his majestic dragon Seasmoke, and how his ultimate sacrifice saved the realm from destruction.
The Origins of Addam of Hull: Secret Velaryon Blood
The tale of Addam of Hull Seasmoke begins in the shipyards of Hull on the island of Driftmark. Addam and his younger brother, Alyn, were raised by their mother, Marilda, the beautiful daughter of a common shipwright. Marilda claimed her boys were fathered by Ser Laenor Velaryon, the first husband of Queen Rhaenyra Targaryen.
However, archmaesters and court gossips in Martin’s lore strongly disputed this claim. Laenor’s sexual orientation was widely known across the realm, making it far more likely that the boys were the secret bastard sons of the Sea Snake himself, Lord Corlys Velaryon. Corlys kept them close, ensuring they learned seamanship, navigation, and statecraft.

(Rider of Seasmoke) (Future Lord of the Tides)
When Prince Jacaerys Velaryon called for Targaryen and Velaryon bastards—known as “dragonseeds”—to claim riderless dragons, Marilda brought her sons forward. While Alyn attempted to tame the wild dragon Sheepstealer and suffered severe burns, Addam approached a dragon that had once lived at Driftmark: Seasmoke.
Claiming Seasmoke: The Silver-Grey Hunter
The partnership between Addam of Hull Seasmoke was immediate and harmonious. Seasmoke was a gorgeous pale silver-grey dragon that had once been the pride of Ser Laenor Velaryon. Following Laenor’s supposed death, Seasmoke nested quietly in the sea caves of the Mont Dragon on Dragonstone, restless and riderless.
Unlike the wild cannibal dragons of the island, Seasmoke was accustomed to men, bridles, and commands. When Addam entered the dragon’s cavern, the beast accepted him without hesitation.

Thrilled by Addam’s success, Lord Corlys Velaryon petitioned Queen Rhaenyra to remove the taint of bastardy from both brothers. Rhaenyra formally legitimized them by royal decree, christening them Ser Addam Velaryon and Ser Alyn Velaryon, making Addam the lawful heir to Driftmark and the seat of High Tide.
The Shadow of the Two Betrayers
The reputation of Addam of Hull Seasmoke was tested not on the battlefield, but in the halls of power. When Queen Rhaenyra captured King’s Landing, she dispatched dragonriders to halt the Green army advancing under Lord Ormund Hightower and Prince Daeron Targaryen.
At the First Battle of Tumbleton, two dragonseeds turned cloak. As chronicled in our report on Ulf the White and the First Tumbleton betrayal, Ulf the White and Hugh Hammer turned their dragonflame upon Rhaenyra’s loyalist garrison.

News of this treachery shattered Rhaenyra’s mental stability. Convinced that all bastards were naturally treacherous, the Queen ordered the immediate arrest and execution of Ser Addam Velaryon and Nettles.
Lord Corlys Velaryon refused to allow his legitimized son to be murdered. Defying his queen, Corlys warned Addam in secret, giving the young knight time to mount Seasmoke and escape King’s Landing into the night mist before the Gold Cloaks could seize the Dragonpit.
The Second Battle of Tumbleton: Proving Loyalty with Fire
Rather than fleeing into Essos or joining the Greens, Addam of Hull Seasmoke embarked on a daring mission to prove his honor. Addam flew across the Riverlands, landing at keeps throughout the godswood to rally broken Black forces.
He gathered an army of four thousand fierce Riverlords under the command of the Blackwoods and the Tullys. Under cover of deep midnight darkness, Addam led his host down upon the encamped Green army at Tumbleton.
The Green forces, drunk on stolen wine and caught completely off-guard, were thrown into chaos. When the enemy dragons Vermithor and Tessarion took to the air without clear commands, Addam did not retreat. He dove Seasmoke straight into the fray, engaging Vermithor in a catastrophic duel on the ground.
- Seasmoke used his agility to slash at the massive bronze beast.
- Vermithor’s crushing bulk ripped into Seasmoke’s neck.
- Tessarion joined the chaotic brawl, resulting in a three-way dragon collision.
All three dragons perished in the mud of Tumbleton. Ser Addam Velaryon died fighting alongside his beloved beast, but his surprise attack completely shattered the Green host and saved King’s Landing from a devastating sack.
The Epitaph That Echoed Through Westerosi History
The legacy of Addam of Hull Seasmoke is carved into the very stone of Driftmark. Following the end of the civil war, Lord Alyn Velaryon sailed to Tumbleton to retrieve his brother’s scattered remains.
Alyn brought Addam back to Driftmark and interred him in a white marble tomb overlooking the sea. On the tombstone, Alyn carved a single word:
“LOYAL”
In an era defined by broken oaths, shifting allegiances, and dynastic murder, Addam of Hull proved that true nobility does not originate from royal birth, but from the choices a warrior makes when honor demands the ultimate price.
Frequently Asked Questions About Addam of Hull

Seasmoke was accustomed to Velaryon blood through his previous rider, Laenor Velaryon. Addam possessed the necessary Valyrian heritage and approached the dragon with confidence and respect, allowing an immediate bond to form.
What happens to Alyn of Hull after Addam dies?
After Addam’s death at Tumbleton, his brother Alyn becomes the legitimate heir to House Velaryon. He succeeds Lord Corlys as Lord of the Tides, earning the legendary moniker “Alyn Oakenfist” for his daring naval victories across the Stepstones.
