Maybe the possiblity of CE having a civil war should it grow too big is not impossible? Remember that this game cannot be won. Even when a single nation rules an entire continent, the game isn't won. That'd simply mean that everything was reset, and in a sort of way would mean that Atamara would simply be renamed to that nation in a way, and new factions/realms would be born inside of it and fight for power. That even happens without controlling an entire continent.
I don't see any reasons to be pessimistic about this at all in fact.
