"The greatest resource our Holy Imperium possesses is the fathomless multitudes of humanity itself. No power is mightier and no force more dreadful when turned to a single purpose. By human hands alone we have remade stars in our image. By this token the wise know that true power lies in the mastery of blood and bone, in the very meat of mankind."
