The Free Cities are nine, powerful independent city-states located in western Essos, across the Narrow Sea. They are engaged in active trade relations with the Seven Kingdoms of Westeros, and their joint territories roughly make up the size of the Westerosi continent. Each city-state is entirely independent of the other, all of them however share a common history in that they were all former Valyrian colonies.

The nine Free Cities are as follows: Braavos, Lorath, Norvos, Pentos, Tyrosh, Myr, Lys, Volantis and Qohor.
