Aalun, Skyka, and Wryy'ethh:
Continuing to follow the wall, but now heading north through the sparse trees instead of west, you notice that the larger lights are actually much closer to the wall on this side. While the south side you had approached at first was mainly dark, not far in front of you the brighter lights were illuminating the trees outside the wall. You could also see large, skeletal looking objects that could only be the basic frameworks of capital-sized starships in construction.
The sounds can still be heard distantly, but they aren't what really catches your attention. Before reaching the section of trees under the bright lights, the three of you can see two points where the wall rises up well above the tree level. At the tops, they spread out into flower-like platforms with what could only be defense turrets on the two outer corners.
Since the two towers are still a good distance away, you can't actually see if there's anyone up on top. However, near the ground between the two towers you do see what looks to be a large gate. The only hint to that is the large creese down the center of it that shows it most likely opens up. Its looks to be big enough to easily accomodate Master Kanas' ship if it could be moved through, and you do notice that there don't seem to be any trees at all in front of it.
