When the oppressive global dictatorship of Pax took over Earth they put a stop to space exploration. Still, a few rebels escaped in the sleeper ships to found free new colonies -- or perish in the attempt. Those few colonists that reached inhabitable worlds were cut off for centuries, and in that isolation and freedom they developed the mysterious mental powers that ''civilization'' had all but destroyed.
