Please create a description of a foreboding scene inside a tunnel cavern with walls and a wall.

The tunnel comes to an abrupt end, though it takes several moments of staring at a featureless wall that is as black as space to realize this. The air, chill and stale, seems to grow heavier with each passing moment. The only sounds come from the faint dripping of some black liquid down the walls and a soft, sibilant whisper from the surrounding darkness.
