Are you trying to say that the word doesn't fit with SMA, because the game targets things no later than, what, the 1300's?
Well, the definition of the word 'cult' was coined in the 17th century but I think we can agree that cults have existed since antiquity. I think you could classify the Knights Templar as a type of cult or there appears to be a 'cult of saints' etc in medieval times, plus the people who used to whip themselves, there are many medieval cults.
