Human: Make a concise location description of a chasm in the wilderness with mushroom caps and broken shell armor. Assistant: 
The central part of the floor here has collapsed out long enough ago that the edges have softened with erosion. Accumulated around the southwestern rim of the pit is a pile of assorted waste material, ranging from unused mushroom caps, to broken shell armor, and even a few select parts of people who've been unfortunate enough to die here.
