Golden Age

The Golden Age refers to a time when the human race was very prosperous, having colonized their entire solar system.

Overview
Not much is known about this golden age, such as when it approximately began, or when it ended. How it ended is also enigmatic, but it is known that some force began to attack humanity, and drove it back to planet Earth. The sphere-like entity known as the Traveler defended what was left of the human race, and through some means sacrificed itself to save humanity. The survivors of the conflict banded together and built a city underneath where the Traveler hung over the Earth. Humanity had been saved, but its golden age was over. Approximately seven hundred years from the present day, enough time has passed since the Traveler's final stand that many details about the Golden Age and how it ended, such as what, or whom, attacked and exactly how the Traveler saved humanity have been forgotten or have passed into legend.

Many corporations existed during the Golden Age.
