What Happened Here?
Béar kneels next to one of the bodies, carefully examining the area around it first for tracks and spoor. He finds nothing around the body that would give a clue as to what happened but when he examines the body he finds it's been dead for awhile - he's unable to tell exactly how long, but it's pretty messy. He also determines that the body has been crushed. Most of the bones in the torso are broken in several places, one arm as well. Enough remains of the internal organs to see that most of them have been pulped.
The party eventually finds 20 bodies, obviously miners. They had set up camp next to a clear, cold stream with a rocky bed. Their tents have been shredded, plainly most of them were killed in their sleep. There are a couple of overturned carts, some woven baskets, and some sort of shattered mining device next to the stream.
Cerallos' examination of the camp yields a little additional information. He determines that only six of the miners had a chance to flee whatever attacked them, and that they ran every direction except north - none of them got very far, anyway. There are no tracks or signs of what attacked them - presumably the tracks of the men and the elements have obfuscated any such.
