An Inheritance of Stars
Imperium of Man
The Imperium of Man is a galaxy-spanning interstellar human empire, the ultimate authority for the majority of the human race in the Milky Way Galaxy in the 41st Millennium AD, and is ruled by the living God who is known as the Emperor of Mankind. However, there are other humanoid species classified as Imperial citizens, mainly mutant offshoots of genetic base-line humans who are known as Abhumans and include such human sub-races as the Ogryns, Ratlings and Squats. The founder and ruler of the Imperium is the god-like Emperor of Mankind, the most powerful human psyker ever born. The Emperor founded the Imperium over 10,000 Terran years ago, and the Emperor continues, at least nominally, to rule the Imperium as both its political master and its primary religious figure, though his badly damaged body is interred within the cybernetic life support mechanisms of the arcane device known as the Golden Throne. Because of this, the Emperor is incapable of interacting with others on a day-to-day basis.
The Imperium of Man is a war-torn empire, teetering on the brink of collapse. For 10,000 Terran years it has been ruled by the deathless Emperor, a being of incredible power, to whom thousands of souls are sacrificed daily. The peoples of the Imperium live in a place where Daemons are real, mutation is frequent and death is a constant companion. To be alive in the 41st Millennium is to know that the universe is a terrifying and hostile place. It is a place where you are but one amongst billions and, no matter how heroic your death, you will not be missed. A truly vast domain, the Imperium is spread amongst the many stars of the galaxy. Its territories encompass untold millions of stars and countless more human lives. In its name, terrible wars are fought and desperate sacrifices made, yet even this river of carnage and blood is a small price to pay, for the Imperium is the guardian of Mankind. Were it to pass into nothingness, so too would the human race, destroyed by enemies uncountable.
The Imperium entered the Argylian Expanse in the year 7017. The first Rouge Traders to enter the sector were surprised to find it already heavily populated by humans. They were told a tale of the Fall of Mankind, and subsequent escape through The Cauldron. The humans of the Expanse were delighted to learn of the survival of the human race and eagerly embraced the tenants of Imperial rule.
In actual fact however, life continued much as it had always gone on; the same people ruled the same worlds with the same old prejudices. On one hand they eagerly accepted Tech in the forms of weapons, ships, and even the mighty Space Marines. Even the Inquisition found welcome in its Ordos Xenos and Ordos Hereticus.
