WE also now know that some geographical factors (natural barriers) can indeed deter the Grimm and that is what determined the current location of the Grimm.

It kinda explains why Vale is between the coast and the forest, Atlas on a frozen continent, Vacuo on a desert... All we are missing is what kind of geography Mistral has. But it seems that very extreme natural conditions are what deters the Grimm.
