This is a large cavern. The ceiling of the cave is 20' high (about the about they went down the stairs). There are three tunnels extending out from the far wall. One to the left, one to the center, and another to the left.
In this cavern are 4 Carrion Crawlers (or Carcass Crawlers).
They will attack as soon as the characters are nearby. They have a small treasure horde nearby.
