Progenitors were the race that created the Jumpweb of the Known Universe by creating the ancient jumpgates that make F.T.L. space flight possible. The Progenitors also created the race of purple-metal, artificially intelligent robots known as Golems. According to the Golems, the Progenitors killed themselves into extinction in an intraracial civil war. "Progenitor" was a human label given to this race. According to the Golems, the Progenitors own racial name for themselves was Karagora, translated as the "unified people." The Progenitors, according to the robotic Golems, were blue-skinned, four-armed humanoids who stood an average of six feet tall and weighed an average of 250-300 pounds. The Progenitors were active in the Known Universe from 30,000 to 10,000 B.R. (13,000 to 33,000 years before the present time). The last of them died by 10,000 B.R.
