Because Humans were so spread out over the empire, a few notable cultures and 'builds' of humans populated different areas.

• Plains People: Stout and hearty folk, humans of the plains were often sturdy farmers accustomed to all kinds of weather and hard labor. 

•  Mountain people: Built for the tough mountainous terrain and frigid weather, the humans of the mountains were often taller in size. They have thicker skin, and are more accustomed to the colder weather than others. 

• Coastal People: These humans live and breath the salt air of the Ulrisin coast. Often sporting leaner builds from years of sailing, and known for their wide variety of seafood dishes. As with most who live their lives on the sea, many Coastal folk are strong-willed and resilient when it comes to the many storms of life.

You, of course, can come up with your own origins, but these are just to name a few! 

Human history is hard to follow since they are vastly spread across the world. Oftentimes humans are known for their nature of being indomitable, which is why some of the greatest rulers and kings in the world's history are human. One such human being Goldwin Ulrisin the Bold, The first Emperor of the Ulrisin Empire. He was known far and wide as a great warrior and leader, conquering the surrounding land and creating a united Empire that dwarfed other kingdoms at its time.
