Halfling

(lived with early humans, though slowly began to diverge away as there cousins began to build cities and larger settlements, preferring to live in small, close-knitt communities. There origin is just as unknown as that of humans, but they remained more secluded and didn't trade and interact with other races)

(Living in the shadows most of history, living in small, agricultural communities often under the control of other powers in return, usually getting the ability to self govern, often in return for paying a tax in the form of food.)

(Think if Amish)

(Halflings used to live as great nomadic warriors, living in a variety of tribes)
