In 97 AC, Queen Alysanne Targaryen wed Prince Daemon Targaryen to Rhea Royce, the heir to Runestone. Though it was a fine, rich match, Daemon found the Vale of Arryn little to his liking, and had no love or affection for Rhea, referring to her as his bronze bitch, a mocking reference to the ancient armor of the Royces. Rhea likewise had no love for Daemon, and they were soon estranged. Rhea later became the ruling Lady of Runestone. Upon the ascension of his brother King Viserys I, Daemon petitioned the king to set aside his marriage, but Viserys denied the request.
In 115 AC, while she was hawking in the Vale, Lady Rhea fell from her horse and cracked her skull upon a stone. She lingered for nine days before finally feeling well enough to leave her bed, only to collapse and die within an hour of rising. Upon learning of her death, Prince Daemon flew to the Eyrie to make a claim on the lands, castles, and incomes of House Royce. In that he failed, as Runestone passed to a nephew of Lady Rhea and the prince's claim was dismissed by Lady Jeyne Arryn.
