30,000-10,000 B.R.-era of time when the Progenitors are active in the Known Universe, including the creation of the jumpgates allowing other races to engage in F.T.L. space flight. Toward the end of this period, the Progenitors start their intraracial, genocidal civil war, create the aritificially intelligent, robotic Golems, and help to spread the Kao Tun, Arvi, Vilaki, Keiki, and the ancestors of the variant human races across the Known Universe.

10,000-5000 B.R.-Golems consolidate their rule over large portion of the jumpweb, and rule benevolently over many aliens including Kao Tun, variant humans, Vilaki, and Keiki. During this same time, bulk of Arvi race develops into their now-familiar "space gypsy" culture by normally wandering the Known Universe, using starships and jumpgates. They often trade with non-Arvi, on-world populations, but sometimes raid them, leading to some armed conflicts with the Golems.
