This certainly explains why only this one continent would be affected, rather than anything in a circular area around the first Face.

Maybe the Mages will only manage to blow up some of them and the others create some magic free zones in the more remote areas away from where people live in which the Demons can revive E.N.D. and do whatever else they plan on doing, while all the mages can keep their magic at the same time.
