Harrenhal Fire and the Deaths of the Strong Father and Son

The Harrenhal fire of 120 AC killed Lord Lyonel Strong and his son, Ser Harwin Strong, along with three retainers and a dozen servants. The deaths removed the king’s Hand and Harwin, heir to Harrenhal, in a single disaster whose cause remained unresolved; in the histories of the Dance of the Dragons, it marks another of the bloody seeds planted before open war.

Return to Harrenhal

Lyonel Strong, Lord of Harrenhal and Hand of the King, accompanied Harwin 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 were sleeping. Both father and son died, as did three of their retainers and twelve servants.

The deaths were consequential beyond the household. Lyonel had been a trusted counsellor on whom King Viserys I had come to rely, while Harwin was his father’s heir. With both gone, Harrenhal passed to Larys Strong, Lyonel’s younger son. The king, already burdened by poor health and the demands of governing, now needed another capable Hand; he ultimately recalled Otto Hightower to court.

An Unsolved Cause

No cause for the fire was ever determined. Some accounts treated it as mischance; others repeated the belief that Harrenhal, the seat of Black Harren, was cursed and brought doom to its lords. Many suspected deliberate arson, but the proposed culprits and motives differed sharply.

Mushroom implicated Corlys Velaryon, suggesting vengeance against the man who had cuckolded his son. Septon Eustace instead suspected Prince Daemon, who might have sought to remove a rival for Princess Rhaenyra’s affections. Another suspicion fell on Larys Strong: his father and elder brother’s deaths left him Lord of Harrenhal. These remained allegations, not established explanations.

Speculation and Political Consequences

Grand Maester Mellos raised the most disturbing possibility: that Viserys himself had ordered the fire. If the king had come to believe the rumors that Rhaenyra’s sons were illegitimate, Mellos reasoned, Viserys might have wanted Harwin removed before he could expose their parentage. On that theory, Lyonel’s death was unintended: his decision to accompany Harwin to Harrenhal had not been foreseen.

The episode therefore preserved uncertainty rather than solving a crime. Its competing explanations connect the fire to rivalries around Rhaenyra, the succession, and the court, while its immediate consequences were plain: the king lost a trusted Hand, Larys inherited Harrenhal, and Otto Hightower returned to royal service. The fire’s place in the account is both personal catastrophe and political turning point, without a confirmed hand behind it.
