Humans

The humans of Khor are both the most mundane and the most interesting of all the races. They are the most mundane because of their lack of magical prowess and the absence of any particular, unique, defining trait. They are, or rather, were, at one point the powerhouses of the land, and had spread across the great world to the farthest reaches they could possibly go. It's this, that makes them interesting. They are the only species of Khor with a truly unique and varied history from place to place. 
See, the fae haven't been around long enough yet to establish a long, complex history. The Hill Dwarves will all tell you the same story about their original departure from their mountain home. Mountain Dwarves will insist that whatever story the current Dwarf King is telling about the past is the absolute truth. Humans, though, you can ask the merchant in Fästnüng, and the fisherman in Seagraves, and the nobleman from Mediera, and they will all tell you a very different, yet cohesive story about their culture and where they have come from. You can ask the Vrykul of the south, or the Khamsin of the north, and you would be hard pressed to find any similarities between their cultures.
