From the introduction:
Here before you lies the wisdom of the ages: the accumulated knowledge of the Blarch, the Notwi, the Chirga, and the magnificent Advawi; the utterances of sage and Vadabaule; the whispers of the departed dead to the movha'jiit; the howls of colliding stars and dying worlds; and the secrets of the Unknowable Other. Before you is the Encyclopedia Imperium, collected by the agents of the Emperor, in this, the sixteen thousandth year of his reign. Read, and be enlightened.
