> there had been forewarning of "Gods" from the east who would conquer the Aztecs

I'm reading a history of Christianity right now, that says this. Apparently the Aztecs had wiped out an earlier civilisation (Toltecs), and the legend is that the defeated king would return as a god and take revenge. The return would occur in a certain year of the 53 year Aztec cycle, and the avenging god-king would come from the East, and be light-skinned (all of which matched up).
