Au Ra are believed to be native to Othard with the Azim Steppe being viewed as the ancestral homeland for both clans.

It seems reasonable to assume that they spread from there in all directions (Though it was mostly the Raen who decided to seek greener pastures), including westward into Ilsabard where they eventually ended up adopting the names and cultural customs of the people in that region, much as they did when they moved east.
