Complete story — includes the ending

Rhaena mounts the dragon Sheepstealer and eventually bonds with him. Aegon and Larys are captured by guards loyal to Rhaenyra. Larys reveals their identities, believing they will make valuable hostages. Alicent finds Aemond on the Iron Throne, who claims Aegon has abdicated. She urges him to seize Harrenhal. Alicent forges a letter from Aemond and sends it to Ormund Hightower to delay the Hightower army. Daemon defeats Jason Lannister's forces and gains new allies, the Winter Wolves led by Roderick Dustin, who delivers Jason's severed head. Addam, Hugh, and Ulf wait to ambush Aemond at Harrenhal, but Alys urges them to leave. The Triarchy engages the Velaryon fleet at the Gullet and sacks High Tide. Lohar breaks from the battle to pursue Corlys. Jace has Rhaenyra confined to keep her from joining the battle. He and Baela fly their dragons, Vermax and Moondancer, to stop the Triarchy. Corlys navigates a rocky pass with Lohar in pursuit. Lohar throws Tyland overboard and rams Corlys's ship, which breaks apart. Corlys falls overboard, and Alyn kills Lohar. Rhaena arrives on Sheepstealer, who attacks ships indiscriminately. Vermax is shot by a scorpion bolt and drowns. Jace is killed by Triarchy bowmen.
