Human: Make a concise location description of a magical scene outside a coastal area with a waterfall, a glass house, and a dock. Assistant: 
Most of the visible coastline is unapproachable black rock rising straight up from the water, but a driftwood dock attached to a small strip of sea-level land provides an entrance to the island's interior: a narrow valley lushly green with dense tropical foliage. A huge waterfall crashing down from a northern cliff is split by a jutting promontory, sending a smaller tributory rushing towards the valley. Nestled under the smaller fall is a large glass house.
