During the War of Conquest, Queen Rhaenys Targaryen flew upon Meraxes to Vaith but found the castle abandoned. During the First Dornish War, Lord Harlen Tyrell and his army marched from the Hellholt to capture Vaith, but they disappeared in the sands.
Cassella Vaith was the third mistress of King Aegon IV Targaryen. Old Lady Vaith was reportedly mad during the reign of King Aerys I Targaryen, though according to Egg, Ser Duncan the Tall could have been more courteous in what he said to her.
