Cast & Characters of House of the Dragon Season 3
Returning Cast: Team Black (Rhaenyra’s Alliance)
The blacks fight for Queen Rhaenyra Targaryen’s claim to the Iron Throne. These are the major players returning on her side.
Emma D’Arcy as Queen Rhaenyra Targaryen
Rhaenyra ended Season 2 reeling from loss but more determined than ever. She now has dragonriders and an army. D’Arcy’s performance carries a quiet fury that will erupt in the war to come.
Matt Smith as Prince Daemon Targaryen
Daemon spent the last season trapped in Harrenhal, haunted by visions. He emerged with a clearer sense of purpose and a renewed loyalty to his wife’s cause. Smith brings a chaotic energy that makes Daemon impossible to predict.
Steve Toussaint as Lord Corlys Velaryon (The Sea Snake)
Corlys commands the largest fleet in Westeros. His allegiance is critical for Rhaenyra’s blockade and the naval battles ahead. Toussaint gives the character a weary dignity that anchors the blacks’ war council.
Sonoya Mizuno as Mysaria
Mysaria has become Rhaenyra’s spymaster and trusted advisor. Her network of informants will shape the conflict from the shadows. She is no longer a side character but a player in her own right.
Harry Collett as Jacaerys Velaryon
Jace is Rhaenyra’s eldest son and heir. He will take on more responsibility, including dangerous diplomatic missions. The war will force him to grow up fast.
Bethany Antonia as Baela Targaryen
Baela is a dragonrider and Daemon’s fierce daughter. She already proved her courage in the skies. Season 3 will give her more to do as the fighting intensifies.
Phoebe Campbell as Rhaena Targaryen
Rhaena is still searching for her place in the war. She does not have a dragon yet, but her story is heading somewhere important. The show has been quietly building her arc.
Returning Cast: Team Green (The Hightower Faction)
The greens support King Aegon II’s claim. They hold King’s Landing but face threats from all sides. These are the key returning actors.
Olivia Cooke as Queen Dowager Alicent Hightower
Alicent’s world crumbled in the Season 2 finale. She realized her sons are monsters she cannot control. Cooke’s portrayal is full of regret and desperation. Watching her navigate the consequences is one of the most compelling parts of the show.
Rhys Ifans as Otto Hightower
Otto is the master schemer who set much of this war in motion. He was sidelined at the end of Season 2 but is far from powerless. Ifans plays him with a cold calculation that always keeps you guessing.
Tom Glynn-Carney as King Aegon II Targaryen
Aegon was badly burned at Rook’s Rest. He is now physically and mentally shattered. Glynn-Carney manages to make the character pitiable and monstrous at the same time. His desire for vengeance will be a driving force.
Ewan Mitchell as Prince Aemond Targaryen
Aemond now rules in his brother’s absence. He is the one-eyed kinslayer with the largest dragon in the world. Mitchell’s intense stillness makes Aemond terrifying to watch. Expect him to unleash chaos.
Phia Saban as Queen Helaena Targaryen
Helaena speaks in riddles that often hide brutal truths. She is grieving and isolated, yet her prophetic visions might be the greens’ only warning of disaster. Saban brings a fragile strength to the role.
Fabien Frankel as Ser Criston Cole
The Lord Commander of the Kingsguard is now Aemond’s right hand. Cole will lead armies into the field. His bitterness and blind loyalty make him a dangerous man on a mission.
New Cast Members in Season 3: Every New Character Explained
The war draws new allies and enemies out of the woodwork. Season 3 introduces several important figures from George R.R. Martin’s Fire & Blood.
James Norton as Ormund Hightower
Ormund is Alicent’s cousin and the Lord of Oldtown. He commands a powerful army from the Reach. His arrival means the greens finally have a seasoned military leader backing their cause. Norton is known for roles in Happy Valley and Grantchester.
Tommy Flanagan as Roderick Dustin
Lord Dustin leads a contingent of Northern men who march for Rhaenyra. He is a tough, no-nonsense bannerman. The North remembers its oath, and Dustin will make sure that vow is honored on the battlefield. Flanagan is famous for Sons of Anarchy.
Dan Fogler as Torrhen Manderly
The Manderlys are a wealthy Northern house with a strong navy. Torrhen represents their commitment to the blacks. His ships and gold will help sustain the war effort. Fogler is best known for the Fantastic Beasts films.
Tom Cullen as Ser Luthor Largent
Largent is the commander of the City Watch in King’s Landing. His loyalty could tip the balance of power inside the capital. Cullen, who starred in Downton Abbey, plays a character with a pivotal role in the story.
The Dance of the Dragons: What Happens in Season 3?
Where Season 2 Left Off
The Season 2 finale set the stage for total war. Rhaenyra secured new dragonriders. Aemond burned Sharp Point and prepared to march. Alicent agreed to open the gates of King’s Landing, believing surrender was the only way to stop more death. But war is already spinning beyond anyone’s control.
What to Expect in Season 3
Season 3 will adapt some of the most brutal chapters from Fire & Blood. The naval battle known as the Gullet is coming. Dragon will fight dragon. Armies will clash on open fields. Major characters will die. The showrunners have promised a season that feels like a relentless sprint toward tragedy. Without spoiling anything, the Targaryen civil war reaches its darkest moments here.
Team Black vs. Team Green: A Quick Guide for New Viewers
If you are jumping in fresh, here is the simplest breakdown. Team Black supports Rhaenyra Targaryen, the named heir of the late King Viserys. Their faction includes House Velaryon, the North, the Riverlands, and most of the minor houses. Team Green supports Aegon II, Viserys’ eldest son with Alicent Hightower. Their power base is the Hightower family, the Westerlands, and the Lannisters. Both sides have dragons. Both believe they are right. Everyone else is forced to pick a side or burn.
