Please describe a spooky cave setting with a small rut, a rock barrier and a guard post.

The remains of an old guard post are here. From the positioning of a small rock barrier, it seems that this post was made to prevent anyone from entering the caves in this direction. A small rut has been worn behind the barrier, apparently from the repeated pacing of sentries at this point. To the west the cave seems to open into a much larger cavern. Dim light can be seen coming from the northeast.
