In the outgoing Dark Ages, early precursors formed of what would eventually become the entrarchies of the present day. Long stretches of expansion, consolidation, and power struggles followed, culminating in the relatively recent Third Entrarchic War, which established Arakuna-Vela as the dominant power of what is now commonly called the Entrarchic Age.
Yet, not every surveyed or populated system across the Void is controlled by entrarchies. Numerous other societies exist, from independent systems to dominions to Outskirters to freetrader networks and beyond, and there are also mobile and even nomadic societies with varying degrees of species homogeneity and specialization.
