Daario Naharis

The Stormcrows are hired by Yunkai to defend the city against Daenerys Targaryen's forces. Daenerys offers the Stormcrows gold if they defect to her. While the Stormcrows deliberate this offer, Daario (having been won over by Daenerys) kills the Stormcrows' captains and pledges the company's support to Daenerys.[5] The Stormcrows aid Daenerys in her subsequent conquests of Yunkai and Meereen.

Following Daenerys' conquest of Meereen, she sends Daario to Lhazar to reopen trade routes between the two regions. After his return, Daenerys takes Daario as a lover but marries the Meereenese nobleman Hizdahr zo Loraq. With Yunkai besieging Meereen, Daenerys offers an exchange of hostages between the two camps to ensure peace, and Daario is amongst those given to Yunkai. However, Daenerys flies away on Drogon, and the Yunkai'i refuse to release Daario until Daenerys' other two dragons are executed.

The television series develops the backstory that Daario's alcoholic mother sold him to the fighting pits when he was a young boy. Daario was trained as a pit fighter and performed so well that he was released from slavery when his master died. After winning his freedom, Daario joined the Second Sons sellsword company.

Under the leadership of Captain Mero and second in command Prendhal na Ghezn, the Second Sons are hired by the slaver city Yunkai to fight against Daenerys' army. Smitten with Daenerys, Daario refuses to obey his superiors when they decide to assassinate her; he instead kills them and presents their severed heads to Daenerys. With the Second Sons under his command, Daario and his men pledge their allegiance to Daenerys. He then assists Jorah Mormont and Grey Worm in opening the gates of Yunkai, allowing Daenerys' forces to conquer the city.

On the march to the neighbouring slaving city of Meereen, Daario unsuccessfully attempts to romance Daenerys. At the gates of Meereen, Daario volunteers to fight Meereen's champion in single combat and swiftly kills him before taunting the Meereenese by urinating in front of the city. After Daenerys conquers the city, Daario persuades her to take him as her lover. When Yunkai begins to rebel against Daenerys' rule, Daenerys sends Daario and the Meereenese nobleman Hizdahr zo Loraq to negotiate with the city's masters.

Daario and Hizdahr are successful in their negotiations with the Yunkish, although the Yunkish insist as part of the agreement upon reopening the city's fighting pits. Daenerys initially refuses, despite Daario's pointing out that his youth as a pit fighter gave him the skills necessary to join the Second Sons and meet her. Daenerys changes her mind after the Meereenese insurgents, the Sons of the Harpy, kill her advisor Ser Barristan Selmy. She takes Hizdahr as her husband but keeps Daario as her consort. After Daenerys flies off on her dragon Drogon during an attack by the Sons at the opening of the fighting pits, Daario and Jorah decide to leave Meereen to find her. Tyrion Lannister tries to join them, but Daario points out Tyrion is better suited to govern Meereen in Daenerys' absence.

Jorah and Daario discover that Daenerys has been captured by the Dothraki, and follow her to the sacred Dothraki city of Vaes Dothrak. They infiltrate the city and meet Daenerys, but she points out that they will be unable to escape the 100,000 Dothraki in the city. Daenerys instead sets fire to the Temple of the Dosh Khaleen, killing the khals but emerges unscathed. Amazed, the Dothraki bow down to Daenerys, and Daario follows suit. While Jorah leaves to find a cure for his greyscale, Daenerys and Daario march on Meereen with the Dothraki. Daenerys flies ahead on Drogon, and Daario arrives at the gates of Meereen. There, he finds the Sons of the Harpy massacring freedmen and leads the Dothraki charge to kill the Sons. With slavery finally abolished in Slaver's Bay, Daenerys decides to return to Westeros and reclaim the Iron Throne. However, she insists that Daario and the Second Sons remain to keep the peace. Daario is dismayed and declares his love for Daenerys, but ultimately agrees, realizing that Tyrion advised her to end their relationship.
