Human: Generate for me a description of a foreboding scene outside a cave with a stone arch and symbols. Assistant: 
A chill breeze bearing a faint odor of decay wafts through the huge stone arch that dominates the eastern end of the tunnel. The arch is worn by dark rivulets of water dripping from somewhere above, the acidic liquid etching deep streaks in the ancient grey stone and nearly obliterating the many symbols of dark gods carved into its pockmarked surface.
