The flames lit the coast for fifty leagues as hundreds of leaking, listing hulks were put to the torch and turned to ash; in the light of their burning, Princess Nymeria named Mors Martell the Prince of Dorne, in the Rhoynish style, asserting his dominion over "the red sands and the white, and all the lands and rivers from the mountains to the great salt sea."
Such supremacy was easier to declare than to achieve, however. Years of war followed, as the Martells and their Rhoynar partners met and subdued one petty king after another. No fewer than six conquered kings were sent to the Wall in golden fetters by Nymeria and her prince, until only the greatest of their foes remained: Yorick Yronwood, the Bloodroyal, Fifth of His Name, Lord of Yronwood, Warden of the Stone Way, Knight of the Wells, King of Redmarch, King of the Greenbelt, and King of the Dornish.
For nine years Mors Martell and his allies (amongst them House Fowler of Skyreach, House Toland of Ghost Hill, House Dayne of Starfall, and House Uller of the Hellholt) struggled against Yronwood and his bannermen (the Jordaynes of the Tor, the Wyls of the Stone Way, together with the Blackmonts, the Qorgyles, and many more), in battles too numerous to mention. When Mors Martell fell to Yorick Yronwood's sword in the Third Battle of the Boneway, Princess Nymeria assumed sole command of his armies. Two more years of battle were required, but in the end it was Nymeria that Yorick Yronwood bent the knee to, and Nymeria who ruled thereafter from Sunspear.
Though she married twice more (first to the aged Lord Uller of Hellholt, and later to the dashing Ser Davos Dayne of Starfall, the Sword of the Morning), Nymeria herself remained the unquestioned ruler of Dorne for almost twentyseven years, her husbands serving only as counselors and consorts. She survived a dozen attempts upon her life, put down two rebellions, and threw back two invasions by the Storm King Durran the Third and one by King Greydon of the Reach.
When at last she died, it was the eldest of her four daughters by Mors Martell who succeeded her, not her son by Davos Dayne, for by then the Dornish had come to adopt many of the laws and customs of the Rhoynar, though the memories of Mother Rhoyne and the ten thousand ships were fading into legend. -- The World of Ice and Fire
