Who Is Alyn Velaryon? ‘House of the Dragon’s’ Bastard Son-Turned-Hand of the Queen, Explained

If you have been watching ‘House of the Dragon‘ Season 3 and found yourself asking who exactly Alyn is and why he suddenly matters so much, you are not alone. What started as a minor character has become one of the most quietly important figures in the entire Targaryen civil war.

Ser Alyn of Hull is a sailor in the Velaryon fleet and a bastard son of Lord Corlys Velaryon, originally from the portuary town of Hull on Driftmark. By the Season 3 finale, that quiet sailor has been thrust into one of the most consequential roles in King’s Landing, and his story is only getting started.

Alyn of Hull’s Origins as Corlys Velaryon’s Bastard Son

Alyn and his brother Addam are both bastard sons of Lord Corlys Velaryon, and he reportedly shaves his head to hide his telltale silver hair, a physical trait that ties him to House Velaryon despite his illegitimate status. He rose through the ranks of the Velaryon fleet and took part in the final stages of the War for the Stepstones, notably saving Corlys’ life after the Lord of the Tides was wounded and fell into the sea.

That act of loyalty planted the seeds for everything that follows. Steve Toussaint, who plays Corlys, has said his character sees himself in Alyn, despite Alyn being illegitimate. Toussaint recalled that before her death, Rhaenys told Corlys these boys need to be raised up, that it is not their fault, and that the burden of the situation rests on him.

Toussaint also explained that Alyn opened up to his father late in Season 2 about what it felt like to grow up in the shadow of the Velaryon house while never being acknowledged. That guilt clearly shapes Corlys’ choices later in the story, and it sets up Alyn’s dramatic rise.

Alyn’s Turn as Hand of the Queen in the Season 3 Finale

The Season 3 finale, titled “The Treasons at Tumbleton,” marks the true turning point for Alyn. After King Aegon II’s shocking survival created a legitimacy crisis for Queen Rhaenyra, Corlys Velaryon stepped down from his position and recommended his son Alyn to take his place.

Corlys had little left to give his sons after the brutal Battle of the Gullet, but he could offer them the protection of his name, and stepping aside as Hand in Alyn’s favor became his final gift. The decision comes shortly after Rhaenyra denies Corlys’ request to legitimize Alyn and Addam, making the promotion feel bittersweet rather than triumphant.

Rhaenyra’s own desperation deepens when she marches on the Great Sept of King’s Landing seeking official anointment, only for the High Septon to refuse her. Cornered and humiliated, she orders her new Hand to kill the High Septon, and Alyn carries out the brutal task, committing an act of religious assassination that stuns the capital.

Actor Abubakar Salim has spoken about just how heavy that decision weighs on his character. Salim admitted it was genuinely hard to pin down why Alyn would go through with the murder, pointing to the moment Rhaenyra tells him he is of a higher power as the emotional hinge of the scene. It is a chilling character turn for someone who, just moments earlier in the season, was solving the Red Keep’s rat problem rather than committing political violence.

Alyn and Baela Targaryen’s Unexpected Romance

Alyn’s personal life takes just as sharp a turn as his political one. In Season 3’s sixth episode, Alyn of Hull shares an intimate kiss with Baela Targaryen, a moment that catches many viewers off guard given the family dynamics involved. The scene comes after tension between Alyn and Corlys over Rhaenyra, with Alyn going to Baela in hopes she can smooth things over with his father.

That connection does not stay confined to Season 3 either. The relationship between Baela and Alyn sets the stage for their lasting impact on Westeros, since the couple eventually has several children together who carry on the Velaryon line. Alyn also has a notable affair during this period with Princess Elaena Targaryen, adding another thread to his complicated romantic history.

Fans of ‘Game of Thrones’ may find this detail especially interesting. Two separate lines of Alyn’s descendants survive well over a century later into the era of ‘Game of Thrones,’ the Velaryons through his children with Baela and the Longwaters through his relationship with Elaena. Notably, the Velaryon descendants become allies of the Mad King during Robert’s Rebellion, directly shaping the Westeros audiences saw in the original series.

Alyn’s Future as a Legitimized Velaryon Lord

Beyond the finale’s shocking violence, Alyn’s long-term arc paints him as one of the more fascinating legacy characters in the franchise. Corlys ultimately agrees to legitimize Alyn, allowing him to formally become a true Velaryon, a rare instance of on-screen bastard legitimization in the franchise.

That legitimization plays out very differently than the last time audiences saw it happen, referencing Ramsay Snow’s own path to legitimacy in ‘Game of Thrones.’ Unlike Ramsay, Alyn’s time as a legitimized heir lasts far longer, and after Corlys’ death, he becomes Lord of the Tides.

Alyn goes on to marry Baela and eventually serves as lord admiral under King Aegon III Targaryen, later earning his knighthood and the title of master of ships. He also enjoys several great voyages throughout his life, ultimately earning the nickname Oakenfist along the way.

It is a remarkable trajectory for a character who began the series as an overlooked bastard sailor, and one that suggests HBO may be quietly building toward a future spinoff centered on House Velaryon’s continued influence over Westeros. With only more story left to unfold, Alyn’s journey from Hull to Hand of the Queen to legitimized lord feels far from finished.

Do you think Alyn deserves to be remembered as a hero for his role in Westeros’ future, or does that Sept killing complicate his legacy for good?
