Touch of Death
From Diablo Wiki
The Touch of Death event is triggered when you encounter a Guard in the Westmarch Commons in Act V who says "This can't be happening! We're all going to die here!". At this point you are attacked by Punishers. After they are slain, a Death Maiden appears and raises the souls of the poor Guard and his comrades.
