Neithan02 is right, if the Emperor dies then the Astronomicon would also, thus rendering communication between the different human worlds nigh on impossible. A new age of strife would probably begin with humanity split into thousands of small kingdoms consisting of a simple planet, others of a couple of star systems. The Great Crusade reunited mankind, if "we" were split up again then mankand would be easy prey for the alien, the heretic and the ambitious.
