I have looked but couldn't find it. I downloaded the Victoria 2 demo and found a excelfile with a list of all the provinces, total of 3246 including the ocean territories which is unnecessary for Warlight.
However, I found maps with names from the original game, Victoria:

The game is supposed to be in the Victorian era (1800s) so some of the names and countries are different.
Ive copied the list to Excel and break down countries and continents to see how it can be divided
