Plotting to avenge a massacre in England, Viking armies converge in Kattegat — but siblings Leif and Freydis exact a different kind of retribution.

With few options left, Rhaenyra summons a trusted knight for a risky venture and plots with Mysaria to catalyze the smallfolk. Meanwhile, Daemon’s unease grows, and Aemond takes steps to reshape the Green Council.

In Rhaenyra’s absence and with no word from Daemon at Harrenhal, Rhaenys tries to keep the peace on the Black Council as Cole mounts a campaign into the Crownlands. In King’s Landing, Aemond continues to undermine Aegon’s fragile hold on authority.  

As ancient grudges resurface, Rhaenys suggests that Alicent may see reason while the men around her seek bloodshed. Ser Criston proposes a bold scheme. Daemon arrives at Harrenhal to raise an army for the Blacks.

As Otto schemes to turn the public against her, Rhaenyra questions Daemon’s loyalty. Meanwhile, Ser Criston Cole concocts a misguided plan for revenge.  

While Rhaenyra struggles to come to terms with her son’s murder, in King’s Landing, Alicent grows concerned that Aegon’s Small Council may lead them to an all-out war. Larys suggests Aegon needs a new Hand, and Rhaenyra arrives at a fateful decision.  

Mourning a tragic death, Rhaenyra tries to hold the kingdom together and Daemon prepares for war.

While Alicent enlists Cole and Aemond to track down Aegon, Otto gathers the great houses of Westeros to affirm their allegiance.

Six years later. With the Driftmark succession suddenly critical, Rhaenyra attempts to strike a bargain with Rhaenys.
