255. Cesspit

As the terravore turns westward, hugging the northern border of the swamp, the waste it produces is drained through an array of many-petaled sphincters that emerge from the wall of a narrow gorge. You trudge through putrid, waist-deep muck as it mixes with syrupy ichor and swamp water. Every now and again, the sphincters disgorge more of the foul-smelling substance. The walls of the pit are covered in slimy moss and lichen, nearly impossible to cling to without slipping. Your only way out is through.
