Slowly, the group heads towards the source of the grinding sound. It has stopped now and in its stead clacking bones and footsteps can be heard. Many of them. It doesn't take long until the dwarves and Elmus (Oog), who seems to get along in the dark rather well for a halfling, can see the first undead ahead. They come straight for the group and there is maybe a dozen of them, animated corpses, skeletons, hunched figures.
Overhead the thunder and lightning have grown in intensity, every now and then a lightning flash illuminates the area for an eye-blink and even more movement can be seen at the sides and behind the advancing undead, but it is quickly obfuscated by the shadows again. It does become apparent, however, that some of the undead are circling the group, trying to get into their back.
