During Aegon's Conquest, Rhaenys Targaryen discovered that the Vaiths had abandoned the castle. The Vaiths attacked the foraging parties of Lord Harlan Tyrell during the First Dornish War. After hearing of the Defenestration of Sunspear, Lord Tyrell intended to capture Vaith and continue east along the river. His army disappeared in the red sands between the Hellholt and Vaith, however. King Aegon I Targaryen and Visenya Targaryen burned Vaith in 9 AC.
At some point between the ending of The Hedge Knight and the start of The Sworn Sword, Ser Duncan the Tall and Prince Aegon Targaryen reached the Prince's Pass in Dorne, probably seeking Tanselle Too-Tall as hinted by the last few words of The Hedge Knight. Dunk's horse, Chestnut, died on the crossing from the Prince's Pass to Vaith. He and Egg rode double on Thunder for an unspecified period of time until one of Egg's brothers gave them Maester. Once in Vaith, Dunk met the aged Lady Cassella Vaith and spoke to her with such lack of grace as to put his own life and Egg's in danger. According to Egg, however, Lady Vaith was mad, so it is unclear if that danger could have been avoided.
