Human: Produce a detailed written description of a serene scene outside of a forest with an opening, palisade, and an arch. Assistant: 
A tall wooden palisade is formed of living trees planted so closely together, their trunks touch and their leafy crowns intertwine. The wall extends quite a ways to either side save for one spot, where there is a gap several feet wide. Branches meet and interlace over the opening, forming a natural, leaf-covered arch.
