Human: Generate a description for where you are in a spooky scene outside of a sea cave with a skeletal hand wedged between two rocks. Assistant: 
A single crack mars the side of the tunnel here. It must surely have appeared in a fairly recent trembling of the island floating here at sea, for the wind does not seem to have smoothed its rough edges. You might be tempted to run a finger over those rough edges, but for the skeletal hand wedged between them.
