A mysterious ancient race of extra-terrestrial beings that had at least some influence in Aquarius, around 100 thousand years before humanity arrived. While by far the most recent of the "Ancient" classification, Antaequan civilisation almost completely disappeared and there remains very little data concerning them. The most widely accepted theory is that the Antaequan were responsible for the xeno-AI known as "Antaeus", upon which most forms of Terran Artifical Intelligence are based on.
