Human: Produce a detailed written description of a gloomy cavern setting with khor'vela vines and tendrils. Assistant: 
Rock walls extend upwards towards the ceiling which ascends towards an opening to the west. A pale green light permeates the area from the tendrils of khor'vela vine that creep across the floor. Boils and sores cover the vines, oozing fluids and emitting a sour odor.
