Complete story — includes the ending
After Viserys's death, Ser Otto and the Small Council plot to crown Prince Aegon. Criston unintentionally kills Lord Beesbury, who opposed the scheme. Kingsguard Lord Commander Harrold Westerling resigns in protest. Otto keeps Viserys's death a secret to fortify the council's position, then coerces the noble houses to switch their allegiance to Aegon. Those resisting are imprisoned or hanged. Otto and Alicent discuss whether to kill or exile Rhaenyra and separately rush to find and influence the missing Prince Aegon: Otto sends Kingsguard brothers Ser Erryk and Ser Arryk Cargyll, while Alicent tasks Criston and Prince Aemond. The Cargylls find Aegon first, but Criston and Aemond forcibly take him. Lord Larys tells Alicent that spies, including Lady-in-Waiting Talya, are within the Red Keep. Alicent approves of eliminating the head spy. Alicent persuades a resistant Aegon to claim his birthright. King's Landing citizens are herded into the Dragonpit to witness Aegon's coronation. Princess Rhaenys, refusing to support Aegon's claim, is held captive. Erryk frees her, and she enters the Dragonpit caverns. Astride her dragon, Meleys, she violently breaches the grand hall, causing mayhem, death, and threatening the royals; Rhaenys then flees King's Landing on Meleys.
