Humans are gonna be pretty self-explanatory. They're basically humans just like us. They will populate most of the planet. That being said, I'm not planning on having a strict segregation of species, so there will be other species living with them, and the will live where the other species do. The majority of human settlements, however, will reside in the more temperate climates. They do, however, reside on every continent, in the icy tundra of the Jotdäl, the deserts of Draedunn and the thick forests of Delphion.
Humans originated on The Desolate Continent, before it became the barren wasteland that it is now.
