Harrenhal

Lore & Background

During the Dance of the Dragons, Harrenhal is a prize for both sides. In season 2 of House of the Dragon, Daemon Targaryen flies to Harrenhal and single-handedly takes the castle for Rhaenyra's cause when its castellan, Ser Simon Strong, willingly yields to him; he summons House Tully and House Blackwood there and experiences mysterious visions within its walls. In season 3, after Daemon has left, Aemond flies to Harrenhal on Vhagar looking for him and kills everyone he encounters, including Simon Strong and his sons.

The Great Council and the Shadow of Harrenhal

Harrenhal serves as a pivotal historical backdrop in the lineage of House Targaryen, specifically regarding the succession crisis that eventually fractured the realm. Decades before the civil war known as the Dance of the Dragons, this massive fortress hosted the Great Council where Viserys I was selected as heir to his grandfather, Jaehaerys the Conciliator. This choice was contentious, as it bypassed Princess Rhaenys Targaryen, who possessed a superior claim based on primogeniture, in favor of Viserys due to gender norms and political maneuvering.

The decision made at Harrenhal set a dangerous precedent that would haunt the dynasty for generations. In the narrative of House of the Dragon, the castle's influence resurfaces during Season 2, where Daemon Targaryen experiences mysterious visions while staying within its walls. These hallucinations suggest that Harrenhal remains a locus of dark prophecy and historical weight, symbolizing the unresolved tensions of the past that continue to plague the Targaryen family.

The fortress stands as a silent witness to the flawed decisions that ultimately led to the devastating war between the Blacks and the Greens.
