The Marches be a vast sea of grass dividing the civilized parts of The Land.
Corvis is a western region of The Land, comprising several small counties. It is a magical place, filled filled with fruitful farms, green rolling hills, low stone walls built up over centuries, and a number of small forests. The people are happy and content. It is an ideal place.
Most of the time. And it depends on what you think is ideal…
A world where, instead of aging in years, the people age in knowledge. So, instead of dying once a general age was reached, they die once they achieve a certain amount of knowledge. A man could live forever if he never learned anything, or could die after reading a few choice books. Of course, the knowledge of the land would be regulated, like medical drugs.
