Out of the Darst and into the night. (Screams Amongst the Stars) [ EDIT ]

Introduction:
You are Spacers, people who have been entrusted with discovering and exploring planets. Your home world isn't Earth, which has been lost millenia ago, but Darst, a terraformed and colonised planet that has seen centuries of history.

Since you were children, you were told myths of the ancient humanity. The Golden Age of Colonisation has ended when the Age of Dark Tears came. A wave of alien death and evil spread and consumed the domains of mankind. It was only through divine intervention did mankind survived annihilation, with the creation of the Creator's Light did the Darkness get repelled. By then, it was too late for many fallen regions, as most stars have been eaten by the Dark Tide.

Darst was said to be one of the planets that almost was wiped by the Enemies of Mankind. As humanity began to reorganise itself, it met bizarre beings. These creatures swore peace, and even made themselves slowly appear like humans. However, these creatures warn humanity that their relationship were to be that as long as they help mankind, mankind has to adapt and listen to their guidance. This has caused many factions to grow displeased, or greedy. Eventually, the human civilisations had their way of communication with each other lost, and their technological strength were controlled and secretly monitored.

It so happens that at least for the past 100 years, mankind finally were able to step out into space freely without "divine intervention" sabotaging their progress…

The Industrial Alliance:

Ethnic Percentage: 20% American, 20% Arabic, 20% Chinese, 20% Japanese, 10% Brazillians, 10% Others.
