Slaver's Bay is a marginal sea of the Summer Sea, lying to the south of the Dothraki Sea, to the west of Lhazar and thousands of leagues to the east of the Free Cities. The climate is very hot. After a first mention in "A Game of Thrones" in relation to slavery, Daenerys Targaryen conquers the three great Slaver's Bay port city-states Astapor, Yunkai and Meereen in "A Storm of Swords". She stays in Meereen throughout most of "A Dance with Dragons".
