Fan Casting Dance of the Dragons

King Viserys I Targaryen had three children by his first queen, Aemma Arryn, but only one, Princess Rhaenyra, survived to adulthood. Lacking a son to succeed him, Viserys began to train Rhaenyra to be his heir. Young Rhaenyra was included in discussions of the affairs of state, and was allowed to participate in meetings of the small council. Many of the nobles took note, and Rhaenyra soon acquired a clique of adherents and supporters. After the passing of Queen Aemma in 105 AC, Viserys named Rhaenyra his heir and hundreds of lords and landed knights paid obeisance to her. Viserys's declaration disregarded precedents from 92 AC and 101 AC. The king remarried in 106 AC, this time to Alicent Hightower, and had four more children: Aegon, Helaena, Aemond, and Daeron.
