The First Dornish War was the last phase of Aegon I Targaryen's Wars of Conquest. With the peaceful surrender of House Stark and House Arryn, Dorne was the only part of Westeros that remained unconquered. Queen Rhaenys Targaryen flew her dragon Meraxes to Sunspear to demand Dorne's surrender. Princess Meria of House Martell refused, warning her to "return at her peril".
