(OOC I am hoping for a response from Lucifer, but I won't keep you all waiting. The door to the next level is hiding, literally in one of the other openings. The time to move to the next level is now. I will give you some indication of what the other tunnels look like.))
The entrance of the cave was a ways back. There were seven doors and the adventurers had explored one. Two were rather small, on the far left of the main entrance. One rat sized, the next kender sized, (where the carrion crawler had disappeared) and the third was a bit bigger. There was total darkness down that way, and the tunnel sloped down for a good ways, maybe fifty feet, before it turned to the right.
The fourth tunnel was the one they were in now. The fifth tunnel was tall and wide in the first twenty feet , then narrowed down and got a bit smaller. But it was still a good six feet in height. It sloped upwards for about thirty feet after that and then turned to the right.
The sixth tunnel was shorter in length, about ten feet tall and narrow. There appeared to be a hole at the end of a narrow passageway. It was also very dark. How deep the hole was could not be seen from the entrance.
The seventh tunnel was interesting to say the least, for it sloped upwards at a very steep rate, at an angle of such a degree that you could not see past the first twenty feet. It had a very soft blue glow coming from the end and smelled odd, like a tang of burning metal.
