Generate for me a description of a foreboding tunnel cavern with strange stalactite-like structures and a ring.
assistant
Strange stalactite-like structures angle downwards from the tunnel's ceiling. Rather than being large at the source and tapering towards the end, they're the precise opposite -- thin as a strand of thread at the ceiling and the width of an opened palm at the loose end. A single circular ring is carved into the surface of each structure at varying levels of height.
