Harlan was the heir of King Qhorwyn Hoare, as Qhorwyn's eldest son had died of greyscale. When Qhorwyn the Cunning was dying, Harlan died suddenly, allegedly due to falling from a horse. Some suggested that Harlan's younger brother, Harwyn was actually to blame, while others attributed Harlan's death to a Faceless Man. Harwyn succeeded as King of the Iron Islands six days after Qhorwyn's own death.
