You are right, I knew that the Sturgians were going to be descendants of the Nords who land 200 years later. Somehow, they are also part Russian so I am not surprised that parts of the Kingdom of Sturgia would divide off to become the Vaegirs, who are the Russians in Warband. Otherwise, who else would be the descendants of the Nords? My hunch was right and those who told me that Sturgians were not viking like are invalid. Obviously, the Sturgians are a mix of the early Nords/Vikings and the Vaegirs/Medieval Russians.
well you claim that sturgian is nord ancestor and split up into vaegir, thats what i want to correct about.
i mean the effect of the weather something like getting overheat, hypothermia, frostbite,(on battlefield) hard movement in snow (i know camel can move faster in sand but not sure is it also in battlefield), or in rain that will be disadvantageous for archer and crossbow, stuff like that.
maybe stuff like that will give some pro to sturgian and aserai which look weak compare to other that have better armor and such.
beside both this culture major historical advantage is due to their climate.
about the flag, i agree with innocent flower, i dont know how rus or slav symbol look like, but the flag is to viking like, at least try mix both, i think this flag is better put on the nord mercenary faction one since its still look good but feel out of place.
