Our names were based on as much as we could get possible to what they would have spoke. The Parthians did not call themselves Parthians, they (as far as we can tell) called themselves Pahlava.

For the groups of peoples, we have selected the most powerful tribe to occupy that tribe's lands, not neighbouring tribes. The exception is the Sauromatae, who were put into one faction do to the extremely fluid nature of their people. If we had an Aorsi faction, that faction would also include Scythians, Roxolani, and other peoples. By having one Sauromatae tribe (but not giving them all of the land controlled by the Sauromatae), we can represent one tribe that, as they expand, would incorporate the Aorsi, Roxolani, and other tribes without holding the land that all of those peoples controlled.
