Generate a detailed description of a spooky scene outside of a cave with ground, serpentine, and a cavern.

Dim moonlight filters in from above, barely illuminating the area. It is clear, however, that each wall of the cavern is spliced with thick veins of serpentine. A thin coat of serpentine dust covers both the ground and the vines that hang down through the overhead crevice. Lack of light makes further progress into the dark cavern impossible.
