Generate for me a description of a gloomy scene outside a sea cave with a bulge and a stone.
assistant
A huge bulge curves out of the wall, filled with gently rocking sea water. The dark pool of water gurgles with every thrust of the waves, but the walls of its confinement keep it mainly separate from the freedom of the wide ocean. One large stone, reinforced with wooden supports, sits directly across from the bulge on the other side of the channel that guts the middle of the road.
