  ====Season 6====
  Tyrion discovers that the Sons of the Harpy are funded by the slavers of Yunkai, Astapor, and Volantis, and arranges a meeting with representatives of those cities to give them seven years to abolish slavery. Despite Tyrion's insistence that compromise is necessary, this solution is met with disapproval by Daenerys' other advisors and the freedmen of Meereen. Tyrion also enlists the assistance of the red priestess Kinvara, who believes that Daenerys is a messianic figure prophesied by her faith and offers the support of the followers of R'hllor. Meereen begins to prosper, but the city's success attracts the ire of the slavers, who fear it will undermine the legitimacy of slavery, and so launch a massive naval attack against the city. Daenerys returns in the chaos, and though she is displeased with Tyrion's failure, she is persuaded by him to obliterate the slavers' fleet and force their ultimate surrender rather than destroy them outright. Soon after, Theon and Yara Greyjoy arrive in Meereen offering Daenerys the Iron Fleet; they are joined by the fleets of Dorne and the Reach, who have defected from the Lannisters. Daenerys names an honored Tyrion as her Hand of the Queen. Tyrion then joins her, the dragons, and her army as they sail to Westeros.
