The rules are badly written (e.g. 'I could find very little on the Mongol Pantheon being that they were shaman not
much of their religion has been pasted down that I could find.') and could do with a good proof read (e.g. The god Ares is spelt as the star sign Aries).
Even worse, the rules for combat are incomplete and therefore the game is unplayable. I am guessing that you roll a D10 less than or equal to a unit's attack value, and defend by rolling a D10 less than or equal to their defense value. This does not, however, explain if there are any limits of which units attack which.
