The Heirs of the Dragon

With both his sons dead, old King Jaehaerys I Targaryen convenes a Great Council to choose an heir. The Westerosi lords select Jaehaerys' eldest grandson, Prince Viserys, over Princess Rhaenys, the eldest grandchild. Nine years into his reign, King Viserys organizes a tournament to celebrate Queen Aemma Arryn's pregnancy, confident she is carrying his long-awaited male heir. The Small Council disregards Master of Ships Lord Corlys Velaryon's warning that the Triarchy, an alliance of Essos' Free Cities, threatens to cripple Westerosi shipping lanes. Hand of the King, Ser Otto Hightower, criticizes Viserys's brother and heir, Prince Daemon, for his brutality as the City Watch commander. At the tournament, the young, handsome Ser Criston Cole, a common-born knight, outcompetes Daemon. Meanwhile, Viserys sacrifices Aemma in childbirth, performing a C-section. Their newborn son, Baelon, dies shortly after. Viserys refuses the council's pleas to appoint a new heir until Otto reveals that Daemon mockingly styled Baelon as, "The Heir for a Day." Outraged, Viserys banishes Daemon from King's Landing and appoints his only living child, Princess Rhaenyra, heir to the Iron Throne, revealing to her Aegon the Conqueror's dream that inspired him to unify Westeros.
