Human: Produce a detailed written description of a chilling scene outside a wilderness guild with water, a waterfall, a lagoon, and a sheet of ice. Assistant: 
The mouth of the cavern passage leads from behind a waterfall into a frozen lagoon. Once-lush vegetation is now glazed over with a coating of ice that has sealed it in a timeless prison. A frozen sheet of ice hangs like a curtain over the outer surface of the waterfall, while beneath, the water still cascades freely down into the lagoon, its natural forces unabated by the arctic conditions.
