- "So he had no one to warn him when his third wife, sensing an advantage, declared that his second wife had been unfaithful, and produced a list of potential fathers of the misshapen child."
Grand Maester Myros spoke against the marriage of Maegor and Tyanna, arguing that Maegor's marriage to his second wife had ruined King Aenys's reign. For this, Maegor beheaded Myros and officially declared war on the Faith.
When Queen Alys miscarried, Tyanna declared that she had been unfaithful, and wrote a list of potential fathers of the stillborn child. The king executed Alys and her father, Lord Lucas Harroway, the Hand of the King. He then marched on Harrenhal and slaughtered the entire Harroway family.
In the books
In The World of Ice & Fire and Fire & Blood, Tyanna was rumored to be the natural daughter of a Pentoshi magister. She was a tavern dancer and later a courtesan. She was the first Master of Whisperers (using the feminine title "mistress of whisperers"). She was Maegor's third wife, and the fourth to die of his six wives.
In 48 AC, she was seized and taken to the dungeons to be tortured. As the Kingsguards Owen Bush and Maladon Moore prepared their tools, she confessed responsibility for the abonimations that Alys Harroway and Jeyne Westerling produced, and vowed that the same would happen to Elinor Costayne. Maegor cut out her heart with Blackfyre and fed her to his dogs. Tyanna's promise about Elinor came true: two months later, she gave birth to a stillborn monstrosity as well.
