How reliable is Fire and Blood, and who were Gyldayn's three sources?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Fire and Blood is not an omniscient account of the Targaryen dynasty. It is presented as a scholarly history compiled by an in-world archmaester, Gyldayn of the Citadel, out of surviving in-world accounts that flatly contradict one another: Grand Maester Munkun's True Telling, the moralising Septon Eustace, and the court fool Mushroom's Testimony.

    • I do want to stress... indeed, I want to shout... that FIRE & BLOOD is not a novel. This is not a traditional narrative and was never intended to be. Some of my fans have objected to the term "fake history" that I've bandied about in past blog posts and announcements in reference to "The Princess and the Queen" and "Sons of the Dragon" and the like. Very well; let's call this one "imaginary history" instead. The essential point being the "history" part. I love reading popular histories myself, and that's what I was aiming for here. Not historical fiction, not fantasy, no... but something more akin to Thomas B. Costain's monumental (and wonderfully entertaining) four-volume history of the Plantagenets. (But with dragons. Did I mention the dragons?)FIRE & BLOOD: On The Way - Not a Blog, George R.R. Martin (25 April 2018) Word of God

    • Eustace's writing is sober, ponderous, and less salacious than that of Mushroom, and Maester Yandel considers Eustace to have been the more accurate of the two. Eustace did not care for Mushroom's preferred monarch, Rhaenyra Targaryen, favoring instead her younger half-brother Aegon II Targaryen. Eustace considered most northmen to be savages.Eustace (Dance of the Dragons) - A Wiki of Ice and Fire primary

    • Mushroom was a dwarf who served as a fool at the courts of Viserys I Targaryen, Aegon II Targaryen, Rhaenyra Targaryen, and Aegon III Targaryen.

    • Mushroom's Testimony is filled with tales of plots, murders, trysts, debaucheries, and many other salacious claims. The fool's account is frequently cited by Archmaester Gyldayn in his Targaryen history, in which it is often compared to the accounts of other historians, like Septon Eustace and Grand Maester Munkun. Many of the wild claims of Mushroom, who according to Gyldayn loved Rhaenyra greatly, are disputed by the account of Eustace, a supporter of Aegon II, Rhaenyra's half-brother and enemy.Mushroom - A Wiki of Ice and Fire primary

  • Why Criston Cole turned on Rhaenyra has two incompatible versions: according to Septon Eustace he slipped into her bedchamber to confess his love and she refused him, while according to Mushroom it was Rhaenyra who unsuccessfully attempted to seduce Criston. The account passes over the difference with the words 'Whatever the way of it', and records that he went from being her staunchest defender to her bitterest foe.▰▰▱▱▱ likely2 points

    • According to Septon Eustace, Criston slipped into Rhaenyra's bedchamber to confess his love, offering to abscond with her to one of the Free Cities where he would pledge his sword to some merchant prince. Rhaenyra refused him, however, saying a Targaryen was meant to be more than the wife of a sellsword, and that if he could forget his Kingsguard vows, he could forget marriage vows. According to Mushroom, however, it was Rhaenyra who unsuccessfully attempted to seduce Criston in White Sword Tower. The spurned princess took solace in Ser Harwin Strong, called Breakbones. Whatever the way of it, Criston went from being her staunchest defender to her bitterest foe, and Rhaenyra soon left for Driftmark with Harwin as her new sworn shield.Criston Cole - A Wiki of Ice and Fire primary
    • According to The Testimony of Mushroom, Rhaenyra still tried to prevent the wedding by giving her maidenhead to her sworn shield, Ser Criston Cole of the Kingsguard, claiming it meant nothing to Laenor, but Criston refused her. However, according to Septon Eustace's history, it was Criston who came to Rhaenyra, offering to elope with her to the Free Cities, but she refused him.Laenor Velaryon - A Wiki of Ice and Fire primary
