Haereg suggested that the ancestors of the ironborn were not First Men, but instead a race of unknown origin from beyond the Sunset Sea who created the Seastone Chair. He ultimately rejected the idea for lack of evidence, however. Archmaester Hake believed the Kings of the Iron Islands from House Hoare were ungodly men, but Haereg believed they were resented by the ironborn because of their tolerance for the Faith of the Seven.
A Feast for Crows
Lord Rodrik Harlaw reads Haereg's book before departing for the kingsmoot to get background information on the subject. Haereg believes it has been four thousand years since the last kingsmoot, whereas Maester Denestan believes it is two thousand.
You may dress an ironman in silks and velvets, teach him to read and write and give him books, instruct him in chivalry and courtesy and the mysteries of the Faith, but when you look into his eyes, the sea will still be there, cold and grey and cruel.—writings of Haereg
