Humans are the dominant racial group on the Continent, forming the majority of inhabitants in both the Northern Kingdoms and the Nilfgaardian Empire. When humans first arrived on the already-populated Continent, they quickly set about conquering the lands already inhabited by elder races. The humans thus established themselves as the dominant race and so elves, dwarves, gnomes, and halflings are now generally referred to as nonhumans.
Hailing from a homeworld destroyed by themselves, humans first appeared in this world after the Conjunction of the Spheres. The Dauk and Wozgor peoples settled on the Continent at some time before the Nordling culture. Scholars speculate that the Empire's native inhabitants hail from a human culture predating those dominant in the North.
Humans and elves are not terribly dissimilar in appearance and generally the same height. However, elves have pointed ears, smaller teeth, and tend to be more delicately featured. While elves tend to live far longer than humans, humans reproduce at a faster rate.
The humans are at war with elves in particular and have a rather poor relationship with the dwarves, halflings, and gnomes. The races do live together in the cities, however the non-humans are forced to pay a levy just for being non-humans. Several pogroms have taken place in the cities. Many of the larger human cities were built on the ruins of elven cities which the humans had burned down, like Vizima and Novigrad.
