Sorry for the lateness of this reply. The internet's been down at work and I have no phone service at home, so I've been stuck. Anyway....
The party makes its way through the jungle to the northeast corner of the wall. They climb up the tallest tree closest to the wall one by one. From here, they can see two Hostiles inspecting the wreckage of the crashed truck while three stand guard outside the gate. Looking inside the wall, the objects at location 5 were not buildings, but trucks. The trucks are parked up against the wall in a secluded area, surrounded by foliage.
One by one, the party jumps out of the tree, hoping to get over the wall and land on one of the trucks to soften the fall. train jumps first, lands safely and moves out of the way. Melkor follows, also landing safely. Spiderman jumps last, but doesn't stick his landing. He lands hard on his right leg, which bruises badly. His leg's swollen, but not broken, so he can still walk on it, but the injury is painful.
The party stands inside the wall, next to the trucks. To their right, there is a small shed, partially hidden in a cluster of trees. Directly in front of them is the largest building, which is surrounded by a row of trees and bushes, which extend around the edge of the building and appear to get more dense. There are currently no Hostiles in sight, although their voices can be heard coming from the west.
