Humans are present almost everywhere in the Cylinder. From the northenest points, following the Great Herd, to the great South, touching the Boiling Ocean under the Circle, they have migrated in almost every possible location. The first tomes of our encyclopedia will describe human groups as several ethnicities, settled or nomadic, nordic or southerner, fishing or farming. The general aspects of these human cultures will be discussed here : their naming traditions, their geographic location and trades, their notable empires. Thanks to the comparison of the current data with more than fifty four other encyclopediae going back up to 3201 AR, a history of thoss ethnicities and their genealogic links to one another could be constructed as well.
