After Prince Daemon Targaryen conquered all but two of the islands in 509 AC during the War for the Stepstones, he declared himself King of the Stepstones and the Narrow Sea, and Lord Corlys Velaryon placed a crown on his ally’s head. The Kingdom of the Three Daughters responded the following year by sending a force led by Racallio Ryndoon. Another of Daemon’s opponents was Qoren Martell, Prince of Dorne.
