Kiyev-Vassia, southeast of Kiyev

These more obscure parts of the world, where there's not a single familiar name anywhere on the map, though we're drawing out an area much larger than Rhode Island.  We're still in present-day undisputed Ukraine, but in the 17th century the southern part, distinguished by the thick borderline, is the land of Vassia, occupied by the Ottoman Empire.  Thus there is a mix between Turkish names for the larger settlements and Ukrainian for the villages.

Kiyev is the last European region we'll see for awhile; hereafter, the region being mapped is a mixture of Turkic and Mongol influences, particularly as we move through the Zaporozhian hetlands, which are essentially all Cossack.
