IIRC there's another one opposite against Ermor about Marignonites acting against Ermor, right?

Yes, there's one where Marignonites go berserk and start destroying everything undead, I.E., Ermor, which is basically like the Ermorian cultist event, but only happens to Ermor.

I thought that was supposed to be because of the nature of the event - it means that the cultists have been covertly building up an underground following, which when it goes overt, has an effect on the faith of the province, even if the defenders manage to defeat them soon afterwards.

It could happen in theory, but is unlikely due to the nature of Dominion spread: Since that event only upsets dominion in one province, and doesn't actually serve as a source of dominion spread, if your dominion has spread to neighboring provinces, which it usually does, you'll remain alive, even if it were to happen in your capitol on turn 3-ish.
