Now, if this is to have any effect, you need to let the undead pass you by, otherwise you'll just be wedged between the dead and the embodiment of malice (a variant of the rock and the hard place, only much worse). Yes, they may leave Maire in peace, but the rest of you...you're fair game!
The only pace that does come to mind is the Masela temple - it might still be hallowed ground to these monsters.
