Det finns en novell som heter "Den sista kyrkan" av Graham McNeil.
Jag tycker att det här är en av de delar du kanske är intresserad av.
"‘I have,’ replied the Emperor. ‘It is my dream. An Imperium of Man that exists without recourse to gods and the supernatural. A united galaxy with Terra at its heart.’
‘A united galaxy?’ said Uriah, averting his gaze from his blazing church as he finally grasped the scale of the Emperor’s ambition.
‘Indeed. Now that Unity has been achieved on Terra, it is time to reclaim humanity’s lost empire among the stars.’
‘With you at its head, I presume?’ said Uriah.
‘Of course. Nothing of such grand scale can be achieved without a singular vision at its heart, least of all the reconquest of the galaxy.’
‘You are a madman,’ said Uriah. ‘And you are arrogant if you believe you can subjugate the stars with warriors such as these. They are powerful to be sure, but even they are not capable of such a thing.’
‘You are right,’ agreed the Emperor. ‘I will not conquer the galaxy with these men, for they are but men. These are the precursors to the warriors I am forging in my gene-labs, warriors with the strength and power and vision to bestride the battlefields of the stars and bring them to compliance. These warriors shall be my generals and they will lead my great crusade to the furthest corners of the galaxy.’
