For five thousand years, earthlings have been locked by the Higher in their solar system Barrier. Human civilization, devoid of access to large space, was forced to develop towards improving its own mind and body.

Mastered psi technologies that allow you to communicate, control your own body and other objects through thought. Huge megacities - an ugly creature of the twentieth centuries - have disappeared from the face of the planet.
