Daeron II, known as Daeron the Good, was the twelfth Targaryen King to sit on the Iron throne. Born the eldest son and heir to Aegon IV and his sister and wife, Naerys, in . After the failed Conquest of Dorne, King Baelor the Blessed, arranged the marriage of his cousin Prince Daeron to Princess Myriah Martell of Dorne as part of a dual marriage pact between the two kingdoms. He also officiated at the wedding ceremony.
Princess Myriah brought many of her native manners and customs with her, and many noble Dornishmen and women flocked to his court, all serving to give life in the Red Keep a foreign flavor, and alienating many of Daeron’s nobles and courtiers. In 170AL they had their first son, whom they named Baelor in Baelor the Blessed’s honor. Three other sons and at least one daughter followed.
Daeron founded a new castle at Summerhall, in the Dornish Marches, roughly where Dorne, the Reach, and the Stormlands come together.
