House of the Dragon Season 3: The Strongest Houses in Team Black, Ranked by Military Strength

House of the Dragon Season 3 will see Team Black rely on more than just dragons to win the civil war. From powerful fleets and massive armies to strategically important castles, Rhaenyra’s allies bring a wide range of military assets to the battlefield. Some houses can field thousands of soldiers, while others punch above their weight through wealth and naval power.

As the Dance of the Dragons intensifies, the strength of these noble houses could prove just as important as the dragons flying overhead. Here’s how Team Black’s major supporters rank based on their overall military power.

11 House Celtigar Is A Modest Force with Ancient Roots

House Celtigar may boast ancient Valyrian blood, but it enters House of the Dragon Season 3 as one of Team Black’s smaller military contributors. From their seat on Claw Isle, the Celtigars can provide ships, wealth, and loyal troops, though their numbers fall short. Their true value lies in supporting Rhaenyra’s war effort rather than leading major campaigns themselves.

As longtime allies of House Targaryen, their loyalty helps strengthen Team Black’s hold over the Crownlands and surrounding waters. They may not field the largest army in the Dance, but the Celtigars remain a dependable piece of Rhaenyra’s coalition.

10 House Massey Is The Sentinel of the Narrow Sea

House Massey may not command one of the largest armies in Team Black, but its strategic location makes it an important ally of the Blacks. Ruling from Stonedance along the Narrow Sea, the Masseys help protect the waters between Dragonstone and the mainland. Their forces are relatively modest compared to major houses, yet they provide reliable soldiers and local knowledge of the Crownlands.

More importantly, their loyalty helps secure key coastal routes that support Rhaenyra’s cause. In a conflict where control of the sea can decide entire campaigns, House Massey serves as one of Team Black’s vigilant sentinels.

9 House Darklyn Is The Harbor’s Defender

House Darklyn is one of Team Black’s more solid Crownlands supporters, anchored in the port city of Duskendale. Their strength comes from a well-trained local garrison and their ability to control one of the region’s key harbors. While they cannot match the massive armies of the North or the Vale, they are far from insignificant when it comes to protecting the coastal areas.

Their troops are experienced in defending walls, holding ports, and resisting naval pressure along Blackwater Bay. When it comes to supply lines and sea control, the Darklyns stand as reliable defenders of the harbor.

8 House Blackwood Has Elite Riverland Warriors

House Blackwood stands out as one of the most battle-tested fighting houses in the Riverlands on Team Black’s side. Though not the largest in numbers, they make up for it with fierce, disciplined warriors and a long tradition of blood feuds that sharpen their edge in war.

Their forces are well-suited for brutal riverland skirmishes, ambushes, and close-quarters fighting where experience matters more than scale. When the war turns messy and personal, House Blackwood is exactly the kind of house Rhaenyra can rely on.

7 House Frey Has A Strategic Stronghold

House Frey may carry a bad reputation for Game of Thrones fans, but during the Dance of the Dragons, they supported Rhaenyra’s claim. While they are not a top-tier military powerhouse in raw battlefield strength, their control of the only major crossing over the Green Fork gives them enormous leverage over movement and supply lines.

In a civil war like this, whoever holds the Twins can slow armies, cut reinforcements, and shape entire campaigns. For Team Black, House Frey is less about brute force and more about turning geography into a weapon.

6 House Manderly Has Wealth & Maritime Strength

House Manderly is undoubtedly one of Team Black’s strongest northern allies. From White Harbor, they can fund large-scale war efforts while also fielding ships that extend Northern influence along the eastern coast. Their levies are some of the strongest in the North after House Stark, making them powerful in land battles.

In Season 3, Torrhen Manderly is expected to serve as a key northern commander, helping organize White Harbor’s forces in support of Rhaenyra’s campaign. With both coin and coordination, House Manderly stands as a crucial backbone of Team Black’s northern strength.

5 House Tully Holds the Command of the Riverlands

As the central authority in the Riverlands, House Tully has real military weight despite the region’s instability. They don’t rely on elite troops, but on numbers. The Riverlands can raise one of the largest combined armies in Westeros when united.

The only problem is control, since Riverlords are often divided, making Tully strength dependent on diplomacy as much as military force. In House of the Dragon Season 3, Oscar Tully—who is now the new Lord Paramount of the Riverlands—is expected to strengthen that fragile unity, bringing the Riverlands’ scattered loyalties under clearer coordination for Team Black.

4 House Arryn Has The Strongest Defensive Position

House Arryn holds the ultimate strategic advantage by being completely locked behind the impenetrable mountains of the Vale. While other Black allies suffer brutal pillaging and territorial losses across the Riverlands and Crownlands, the Vale remains entirely untouched and pristine.

Because their borders are impossible to breach, Jeyne Arryn can safely hold back her massive army until the perfect moment. They may not always move first in the Dance, but their armies are well-trained, heavily armored, and capable of dominating any open-field battle once deployed.

3 House Stark Is A Northern Military Giant

As the dominant military power of the North, House Stark rules from Winterfell with vast territory and hardened soldiers. Its strength comes from scale and discipline, as the North can raise large armies that are tough, experienced, and loyal once called to war.

We do remember Jace serving as the diplomatic force, traveling north to secure House Stark’s support for Team Black. His alliance with the Starks and the Northern forces leads to Season 3’s introduction of the Winter Wolves, which are not only a political victory but also a promise of military reinforcement.

2 House Velaryon Possesses Naval Superpower

House Velaryon is, without a doubt, Team Black’s undisputed naval powerhouse, controlling the seas from Driftmark with unmatched maritime strength. Their fleet dominates key waterways like the Narrow Sea and Blackwater Bay, making them essential for movement, supply lines, and blockades.

In Season 3, House Velaryon’s ships will be crucial for the upcoming Battle of the Gullet, which will see their fleet clash with the Triarchy. What makes them especially dangerous in Season 3 is how their naval dominance pairs with dragon power. While dragons control the sky, the Velaryon fleet controls the water below.

1 House Targaryen Has Dragon Supremacy

Of course, the members of House Targaryen are the main players in the Dance of the Dragons, with its greatest weapon still unmatched in Westeros: dragons. Their military strength isn’t measured in soldiers or fleets, but in airborne dominance.

After the events in Season 2, Team Black seemingly has the upper hand in the next season, as not only have they found new riders for their dragons, but they are also set to move to King’s Landing. With several fire-breathing beasts at their disposal—far more than the Greens—they are certainly positioned to dominate the war this Season 3.
