It is midnight in the Imperium of mankind. Monsters stalk the void, alien reavers descend upon colonies without mercy, and unwary ships can get lost between stars. What historical records survived The Darkening tell us it wasn’t always this way. Long ago Earth was the central hub of a galactic empire that kept expanding in its quest for precious minerals and proof of other life.
Planet after planet they explored, only finding first dust and microbes then only ruins and remains. It was among these ruins that the earthlings first discovered the means to unlock their full mental potential. Those now awakened fused Psychic power and human technology giving rise to the Psions, a ruling caste of warrior psychics. The rose to power and fueled an unprecedented era of peace and prosperity.
What happened next no one is certain of. All that is known is that a great blanket of darkness swept out of a distant black hole and spread across the galaxy. This darkness settled on some worlds and ignored others, it targeted those worlds that had more psychic potential. Ships trying to enter the darkness were destroyed, light could not penetrate, nothing could get through or lift the darkness. These worlds were cut off and the great empire was scattered and divided. Beginning an Era known as The Darkening, during which the once united ruling Psions fragmented into separate ruling houses (each a master of one discipline) fighting amongst each other for dwindling resources.
For one thousand years this darkness stood before it began to dissipate. The psions of today are merely a former shadow of the great ones of before. With The Darkening fading, the remaining psion families leapt at the chance to recover lost disciplines and technologies. To wrest power from the space graves and leverage it against the other houses.
