Human: Please a ledge overlooking a cavern with a waterfall, pond, crevice, and glass wall. Assistant: 
The ledge is barely wide enough for a person to stand, but offers a good view of the cavern. To the west is a pond with a waterfall in the corner and on the opposite wall is a crevice, with haunting sounds coming from it. All the way to the south is a tall glass wall, sparkling with all the little light that hits it, illuminating the cavern.
