For the sake of visualization, this is a general area of appearance of the bandit camp.

Instead of a building however, the front entrance (The nearest entrance to the firepit you see in the open area) is converted to a Ravine entrance into the ground, though the underground portion is of the same size and dimension of the building, only underground. There is no other entrance/exit. The circular area is the watch tower made of wood. The area you see in that image is void of trees, but everything outside of it has numerous trees around it. The structure to the bottom left is a shack of sorts where supplies are kept, also made of wood. Also just to clarify, while Djarkel is certainly dark and deary, it's not completely barren. Have to have farm land and all. Sure it may not have as many lush forests as Eania, but that's because they have a tendency to deforest en masses.
