The samurai own south eastern states like Florida, Georgia, South Carolina, etc
The knights own Alabama, Tennessee, Kentucky, etc
The Vikings own Maine, New York, Michigan, and much of Canada etc
I came to this conclusion because these areas fit most of the geography of The myre, ashfeld, and valkenheim. The other differences can be explained by the cataclysm.
Here’s my theory: Eric the red was successful and Vikings own canada and northern states. This prompts earlier expansion of the rest of Europe, explaining knights presence. The samurai possibly came later and took land from the knights. Then the cataclysm happens a few hundred years later.
