10 Things Every Fan Should Know Before House of the Dragon Season 3

House of the Dragon Season 3 now escalates the Targaryen civil war in ways fans have been waiting for since the first episode. This month, a new chapter begins, bringing more fire and blood. We’re getting an all-out war, so it’s good to remember a few things from previous installments before we charge ahead.

The Dance of the Dragons has completely fractured the royal house. As Team Black and Team Green gather their own armies and alliances, we’re also seeing more dragon action. Here are ten things every House of the Dragon fan should know before stepping back into the fire.

1 The Dance of the Dragons Officially Begins In Season 3

The Dance of the Dragons is no longer looming on the horizon—it’s officially in full motion in Season 3. Showrunner Ryan Condal has teased fans that the show won’t waste a second this time around, as it will open with “arguably the craziest episode of television ever made,” via Entertainment Weekly.

For two seasons, the Blacks and the Greens have been tiptoeing around open war, but that ends now. Every major house has picked a side; dragons, fleets, and armies are being deployed with deadly intent. This is the point of no return, where the Targaryen civil war turns fully into all-out devastation.

2 Vengeful Rhaenyra Is Here & She’s No Longer Playing Defense

After seasons of loss, betrayal, and restraint, Rhaenyra is now entering her new phase with a far more hardened and vengeful mindset. The days of reacting to the Greens are over, which means no more secret meetings or cautious diplomacy. She is now set to take King’s Landing on her own terms.

Fans expressed dismay in the past over Rhaenyra’s hesitation to go fully into “villain mode.” In Fire & Blood, she is more ruthless and uncompromising. The usurpation of the Iron Throne and Lucerys’ death should push her toward a more vengeance-driven approach to reclaim what she believes is hers.

3 Daemon Recommits to Rhaenyra After His Experiences at Harrenhal

Daemon’s time at Harrenhal, though slow for some fans, changes how he sees the civil war and the future. He leaves with a clearer purpose after being forced to face his past and the cost of chasing power without direction.

Reaffirming his loyalty to Rhaenyra means we’ll see him fight side by side with his queen and aid her in seizing the capital. On the other hand, it brings a lot of tension, as the Rogue Prince has always been unpredictable, so we’ll have to see how far he goes when ambition, loyalty, and personal desire inevitably collide.

4 Aemond Becomes Team Green’s Most Dangerous Weapon

From how Aemond acted in Season 2, fans can already tell he will have a lot of shocking scenes in the upcoming installment. Now acting as the Prince Regent, he has become the Greens’ most formidable weapon. With Vhagar at his command, he has the realm in his grasp.

Aemond has also shown he’s willing to act recklessly, even against his own family. After his supposed attempt to end Aegon’s life, it has become clear that he wants the throne for himself. At this point, he isn’t only a threat to the Blacks but could be a danger to the Greens themselves.

5 The War Cannot Be Won by Dragons Alone

Season 2’s final episode gave us a glimpse of the different houses fighting for the warring royal family. Dragons may rule the skies, but they can’t hold land on their own. As the war escalates, castles, cities, and supply lines depend on ground armies.

This new season, we’ll be seeing all the recruits and alliances made by each team, from the Winter Wolves and House Blackwood to the Hightower host and the Triarchy. Indeed, battles in Westeros are won not just with dragonfire, but with soldiers willing to march, fight, and die for their cause.

6 Corlys Velaryon’s Fleet Is Now The Most Important Military Force

The Battle of the Gullet marks the beginning of a war with no turning back. To secure the blockade, House Velaryon’s fleet will have to fight to the death. As one of the strongest naval forces in Westeros, Corlys’ ships will have to ensure the Greens don’t break their hold on the eastern coasts of Westeros.

The Sea Snake may be one of the most overlooked characters in the series, but Season 3 teases that he will get more screen time as he leads the fight against the Triarchy forces, led by Admiral Sharako Lohar. In many ways, Corlys’ fleet becomes the foundation of Team Black’s entire war effort.

7 New Characters and Powerful Allies Are Entering The Story

House of the Dragon Season 3 will bring new faces into the fold, and there will be quite a few of them. Ormund Hightower and Daeron Targaryen will join the Green forces, while Roderick Dustin of the Winter Wolves and Luthor Largent of the City Watch fight for the Blacks. Others debuting include Alysanne Blackwood, Torrhen Manderly, Adrian Redfort, and Jon Roxton.

The Northern and Riverlands forces joining the war prove that the conflict has become more serious than ever, and that each side is more intent on securing the Iron Throne. Some of these new names are also expected to remain until the final season.

8 The Opening Battle Can Rival Game of Thrones’ Greatest War Scenes

The Battle of the Gullet is set to open Season 3 with a massive clash that could potentially rival Game of Thrones’ Battle of the Bastards or Battle of Winterfell. This isn’t just a skirmish at sea—it’s a full-scale naval battle backed by dragonfire and fleet warfare.

The scale of destruction is expected to be enormous, with ships burning and dragons turning the sky into a battlefield. If it delivers on its promise, the Battle of the Gullet could become one of the most unforgettable moments in the entire franchise.

9 The Next Phase of the War Will Be Fought on Land, Sea, and Sky

Season 3 is expected to feature several storylines depicting brutal battles, and it seems like we’re going to see them all unfold on the ground, above water, and across the sky. The Fishfeed and Butcher’s Ball will be fought on land, while the First Battle of Tumbleton will see Tessarion, Vermithor, and Silverwing take to the skies. The Fall of Dragonstone teases a showdown between Aegon and Sunfyre versus Baela and Moondancer.

This feels like the season where the scale finally matches the promise of the Dance of the Dragons. Every battlefield is active at once, and no corner of Westeros is untouched by the war.

10 The Dragonseeds Are Changing Westeros’ History Forever

The Red Sowing was one of the most memorable events in Season 2, as Rhaenyra successfully found new dragonriders in the form of Targaryen bastards. This strengthens the Blacks’ firepower and gives them an advantage over the Greens.

As readers know, Hugh Hammer and Ulf the White will switch sides and betray Rhaenyra, shifting the course of the conflict. Season 3 will let us know if these dragonseeds will remain loyal or turn against her completely.
