Let's look at what we know. There is a Siberia, Africa, Paris, Indian, Egypt. We know this because it states this is where the magicians came from. We know there is an Italy, Turkey, Three Kingdoms, something know as the Empire, and a Southern America. We know this is because those were the building styles noted when they crossed the Breach into Malifaux the first time. This was all in 1787. So Earthside is pretty similar to earth for the most part.
