Please generate a brief description of a foreboding scene inside a tunnel cavern with cracks and a deep fissure.

A steady *drip-drip-drip* echoes off of every facet of the surrounding rock walls, lending a near-deafening reverberation to the cramped, enclosed space. Directly overhead and continuing down one wall, a deep fissure proves to be the source of the watery incursion. A spiderweb of cracks spreading from it lend an air of impending danger to this part of the tunnel.
