The Harrenhal fire and the deaths of Lyonel Strong and Harwin Strong were a pivotal, unresolved episode in the years before the Dance of the Dragons. In 120 AC, a fire in the tower where the lord and his heir were sleeping killed both men, three retainers, and a dozen servants. The blaze removed the king’s Hand and the heir to Harrenhal at once, while leaving the question of responsibility open to suspicion and competing explanations.

Background and the Fire

Lyonel Strong was Lord of Harrenhal and Hand of the King; Harwin, Ser and Lyonel’s heir, had accompanied his father on his return to the great, half-ruined castle beside the lake. Shortly after they arrived, a fire broke out in the tower where they slept. Both father and son died, as did three of their retainers and twelve servants. The chronicle places the deaths among the bloody seeds of the Dance, although Viserys I would reign for another nine years.

An Unresolved Cause

No cause for the fire was ever determined. Some accounts treated it as mischance; others associated Harrenhal, once the seat of Harren Hoare, with a curse that brought doom to its holders. Many suspected deliberate arson, but the proposed explanations remained allegations rather than established answers.

Mushroom blamed Corlys Velaryon, presenting the fire as vengeance against the man who had cuckolded his son. Septon Eustace instead suspected Daemon Targaryen, who might have wanted to remove a rival for Rhaenyra’s affections. Another theory pointed to Larys Strong: with his father and elder brother dead, he became Lord of Harrenhal. These suggestions assign very different motives to the same unexplained blaze, and the record does not resolve the competing claims.

The King’s Hand and the Succession

Grand Maester Mellos raised the most disturbing possibility: that Viserys himself had ordered the fire. If the king had come to believe the rumors about the parentage of Rhaenyra’s children, he might have wished to silence Harwin, whom the rumors implicated. On this account, Lyonel’s death would have been unintended: the king could not have foreseen that Lyonel would choose to accompany his son back to Harrenhal. The chronicle presents this as speculation, not proof.

Lyonel’s death also left Viserys without a trusted Hand. The king had relied on Lyonel’s strength and counsel, but, burdened by illness and the work of governing, needed someone to share that work. He briefly considered Rhaenyra, then Daemon, before choosing familiarity and recalling Otto Hightower, who had served as Hand before. The fire thus altered both Harrenhal’s lordship and the composition of the royal government, even as its own origin remained unknowable.

Significance in the Chronicle

The event is narrated through uncertainty: a documented catastrophe is followed by suspicions that cannot be confirmed. Its consequences are clearer than its cause. Lyonel and Harwin were dead, Larys inherited Harrenhal, and Viserys turned to Otto for counsel; whether the fire was accident, private revenge, political murder, or a royal command is left unsettled. That gap makes the deaths a turning point in the account of the gathering crisis, rather than a solved conspiracy.
