‘House of the Dragon’ Family Tree Season 3: How the Targaryens, Hightowers, and Velaryons are connected

The House of the Beast Season 3 is here, and you know what that means: It’s time to step up to the more complicated branches of the Targaryen family.

In the first two seasons of The House of the Beastsome of these branches have been pruned. (RIP to the many Tages who perished in this bloody show.) However, Season 2 also added its fair share of new shoots, further complicating the knotted web between Houses Targaryen, Velaryon, and Hightower. Season 3 has gotten even weirder, with a new death and the reveal of the face of another Daeron Targaryen. If you’re looking for a refresher on that web as you head into the second half of Season 3, we’ve got you covered.

Below, you will find the Targaryen family tree as it stands The House of the Beast Season 3, episode 4, and a list of characters and how they connect.

Which Targaryens have died since Season 2?

There were two significant deaths in the Targaryen family in Season 2: one on the side of the Greens and one on the side of the Blacks.

Queen Rhaenyra Targaryen’s (Emma D’Arcy) camp has lost Princess Rhaenys (Eve Best), also known as the Queen That Never Was. Meanwhile, King Aegon II Targaryen (Tom Glynn-Carney) and Queen Helaena (Phia Saban) lose their youngest son Jaehaerys when the gold-robed Blood (Sam C. Wilson) and the rat-catching cheese (Mark Stobbart) kill him on the orders of Prince Daemon (Matt Smith).

There are still plenty of Targaryens left standing, however. Here’s what to look out for in season 3.

Rhaenyra leads the Dark Team branch of the Targaryen family, with her husband/uncle Daemon by her side. (It was also touching for a minute in Season 2, but after a life-changing trip abroad to Harrenhal, full of witches and visions, Daemon is finally ready to accept Rhaenyra as his queen.)

Their two young sons, Aegon and Viserys, are on their way to Pentos for safety after a small pit stop in the Vale. However, Rhaenyra and Daemon’s children from their previous marriages are in Westeros and are caught up in Rhaenyra’s fight for the throne.

Rhaenyra’s son Jacaerys (Harry Collett) and Daemon’s daughter Baela (Bethany Antonia) are both dragonriders. Daemon’s other daughter, Rhaena (Phoebe Campbell), doesn’t have a dragon, which is why she was removed as a guardian for Aegon and Viserys. However, when they went to Pentos, he stayed behind in the Vale, hoping to tame its wild dragon Sheepstealer. Starting in Season 3, he successfully claimed the Sheepstealer, but at a cost: He went awry during the Battle of the Gullet, and his meddling led to Jace’s tragic death. Now, Rhaenyra wants the head of the Sheepstealer rider, and only Daemon and Lady Jeyne Arryn (Amanda Collin) know the truth about who he is.

Dowager Queen Alicent Hightower (Olivia Cooke) remains the matriarch of Team Green, though she grows to regret her role in the succession war. (In fact, he deeply regrets giving up the Iron Throne to Rhaenyra.) He had four children with the late King Viserys (Paddy Considine).

The eldest, Aegon, remains king of Westeros. His younger brother Aemond (Ewan Mitchell) tried to kill him in a dragon fight at the Battle of Rook’s Rest, and when Aegon recovered from his worst injuries, he escaped to King’s Landing with the help of Larys Strong (Matthew Needham). Aemond is now Prince Regent, and Alicent is trying his best to get himself and his daughter Helaena out of harm’s way.

Alicent’s young son Daeron (Benjamin Evan Ainsworth) makes it official The House of the Beast The first episode of Season 3, episode 4, even though he’s been hiding in plain sight since the Season 3 premiere. He is a ward of House Hightower and rides to Lord Ormund Hightower (James Norton), who hatches his own plot – involving the fake Daeron – to put him on the throne.

In addition to Alicent, the rest of House Hightower continues to be a major player The House of the Beast. Her father, Otto Hightower (Rhys Ifans), a former Hand of the King, was the first Green loyalist to be killed under Rhaenyra’s rule. Elsewhere, Alicent’s brother Gwayne (Freddie Fox) has been roaming the Seven Kingdoms with Ser Criston Cole (Fabien Frankel), a nightmare we wouldn’t wish on even our worst enemies.

The House of the Beast Season 3 also introduces a new member of the Hightower family: Lord Ormund, head of House Hightower. His late father Hobert (Steffan Rhodri) was Otto’s older brother, making Ormund Alicent and Gwayne’s cousin.

Rhaenyra’s hand is Corlys Velaryon (Steve Toussaint), also known as the Sea Serpent because of his military prowess. Over time The House of the Beasthe is survived by his wife Rhaenys, and their children Laena (Nanna Blondell) and Laenor (John Macmillan).

However, Season 2 revealed that Laena and Laenor were not the only descendants of the Corlys. He also has two bastard sons, Alyn of Hull (Abubakar Salim) and Addam of Hull (Clinton Liberty). Their mother Marilda, who does not appear in the show, was a shipwright. The House of the Beast it mainly refers to Marilda in the past tense, meaning she is dead, hence the gray in our family tree. However, at this point in the Fire and Bloodhe is still alive.

Although Corlys didn’t truly acknowledge Alyn and Addam before Season 2, the two have become a very prominent part of his life — and the show. Alyn is a notable sailor on the Corlys’ ships, and Addam became a dragonrider. Because of his Valyrian blood, he now rides Seasmoke, Laenor’s old dragon.

Characters of dragons: Addam, Ulf the White, and Hugh Hammer

Addam isn’t the only new dragonrider to join Rhaenyra’s ranks in Season 2. Smallfolk Ulf the White (Tom Bennett) and Hugh Hammer (Kieran Bew) have also sought out dragons. Ulf rides Silverwing, the dragon of Rhaenyra’s grandmother Alysanne, while Hugh rides Vermithor, the dragon of Rhaenyra’s grandfather Jaehaerys. The two, like Addam, are bastards of Valyrian blood, earning them the nickname “dragonseeds.” Although they are not yet officially recognized as Targaryens, they will have a big role to play in the upcoming wars.

The House of the Beast Season 3 premieres June 21 at 9 pm ET on HBO and HBO Max, with a new episode every Sunday.
