You see, from the ridge line, a small camp surrounded by sturdy stone walls. The walls are only about ten feet high, but they have an unusual structure. Instead of the temporary buildings of the mercenaries (tents and small cabins) being contained within the wall like a normal fort, everything appears to have been built on top of earth that fills the entire 10 foot box. What you have is a 10 foot tall plateau with stone walls and an earthen middle.
It appears that there are around twenty tents that would fit a man and a half each. Other than the tents, the only structures are the corner towers (which are each 15 feet taller than the walls, and made of stone) and one center tower that is 10 feet wide, but has a diameter of at least 60 feet.
The entire base appears to be roughly 600 feet on each side, and it appears that temporary wooden bridges are set down near each tower, but none of them have been lowered to allow incoming traffic. The walls of the buildings look very old, and very stoic. There are large cracks that run along the side of the wall you face, and they seem to run very deep into the structure. The shape of the walls form an almost perfect square, and from your angle it gives the slight appearance of a crown studded with fire, due to the small campfires spread about.
