3: Demons broke into the world somewhere below the underground city Hammersdeep, because a evil necromancer known as the forked tongue traveler has made a weak spot in the fabric of reality. When the demons broke through it, they made their way up to the city and slaughtered everything and hung the bodies from the ceiling. They have since moved on and some of there minions might even have reached the surface by the time the PCs reach the area. A demon/undead horde would be a significant problem for the PCs and the residents of the Nentir Vale.
