396 CCCXCVI. The Groan

Walking, he noticed that the lowest point of that vertical and almost a hundred meters deep cave, was a circumference similar to the breach on the surface, but smaller, the diameter of which was only a few tens of meters.

"I have a mission for you, my friend..." 

"A mission? I thought I was already on a mission... what is it?"
