Ancients is the name given to a race of intelligent, alien beings who inhabited various locations in this portion of the galaxy approximately -300 000. Archeological evidence recovered from excavations of the few known Ancient cities indicates that the race destroyed itself during a 2000 year conflict known as the Final War, which left only ruined cities and shattered planets.
The Ancients were responsible for several major features within the region now occupied by the Imperium. Their warfare resulted in the large proportion of asteroid belts throughout this spiral arm. There is evidence that they created the multi-world rosette at Tireen (in the Vargr Extents). Scattered empty cities (most severely damaged by war) stand as evidence of their conflict; most, however, are under investigation by the Imperium and are not open to the public.
The Ancients are generally accepted as responsible for the dissemination of Humaniti within its current domain when they transplanted genetic stock from Terra to at least forty worlds across a span of some 360 parsecs. Similarly they were also responsible for the creation of the Vargr through the genetic manipulation of carnivore/chaser animals. Apparently they used Terran canine stock acquired at the same time as Humaniti. See also Antiquity, Egg, Humaniti, Solomani Hypothesis, Vargr.
