Human: Create a foreboding scene in the wilderness with thick gnarled roots and strips of leather. Assistant: 
Thick, gnarled roots protrude from one side of the tunnel and create a tangled mess that makes traveling through it difficult. Strips of leather and softer materials are interwoven in the writhing mass, each having been ripped from the garments of those who tried to pass through. After brushing against one of the roots, it becomes clear why the passage is so difficult -- the roots have been petrified from countless years in the damp tunnels.
