The Atmorans were all hunters. The Nords didn't know agriculture until they arrived in Tamriel. That's why they don't have agricultural deities like Zeht. I mentioned this.
I know, and I did not contradict it.
I never excluded the idea that they don't have farms. However, they can still raise animals in alpine regions such as mountain goat. Contemporary Nord culture is more sedentary, though more nomadic Nords would still rely on hunting.
That was my point, to say that Nords would have change since the Atmoran emigration. And Though alpine region animal raising might very well be possible, I find it much more believable that they wold herd animals in "valleys" and "open field" regions, and probably move animals such as reindeers (or anything alike), like the Sami people did and still do. But to support big cities, and even to develop a city-culture, large grain production (and supporting) seems to be inevitable. Farming is much more prosperous occupation than hunting, and when once learned from the Tamerielic people, most Nords would probably have settled and built farms of their own.
Just to make things clear, I'm no longer saying Nords would have a almost-only-grains kind of diet, more wanting to prove that they would rather have fairly balanced food culture.
