In the finale the Iron Throne, Daenerys addresses the surviving Unsullied and Dothraki, calling for them to help her 'liberate' (from her twisted perspective) the rest of the world- something Jon Snow kills her to prevent.
The Unsullied leave what's left of King's Landing for the island of Naath but what of the Dothraki? Do they return to their homeland? Or do they claim any territory in Westeros?
