In the year 2126, mostly women survive 100 years after the Cataclysm. Patriarch power has ended. Of the billions of people, only a few million survive to build a matriarch society. Mothers' Rules stress the development of humane technology for humane survival. To insure human survival, the X-Terra project creates tunnel-towns in the Moon and Mars. Visitors invite matriarchs to extend the human family back to their first homes in the Regulus, Sirius, and Orion star systems. With the help of the Visitors, matriarch technology perfects wormhole travel to speed home-making in the stars.
