Write a short description of a spooky cavern with water and a tunnel.
assistant
The sound of dripping water carries in faintly from the north, though curiously flat in tone. The tunnel here seems to have a strange acoustic quality, making it easy to blame the most ordinary of sounds for that of something breathing, watching just outside the field of vision. It is, however, harder to dismiss the darker patches of gloom that seem to move along the walls as any natural phenomena.
