Bear with me on the fog of war here. MapTool kind of sucks so I'm doing the vision manually, and considering angles on a 2D surface between multiple levels is not incredibly intuitive!
The rope ladder proves trustworthy, and the five of you ascend it one-by-one to regroup with Hadrurus near the top, who looks no worse for wear. Now standing on the southeast tower, you peer around the fort to get a better understanding of its layout.
To your north along the battlement is the northeast tower, which stands a story taller than your current level. To the west is the southwest tower, which sits at a similar height. You can see the ruins of a watchtower there, but from the current angle, the sentry previously seen there does not have a straight shot to you without leaving their post.
Further west is another circular tower at your level, though it stands empty for now. Josie would recall seeing the light from another lantern just north of there, around the northwestern portion of the battlements.
Inside, the fortress looks to be in various stages of disrepair. What may have once been well-kept grounds has been reduced to packed dirt, swollen and unsteady by the constant rains.
There appear to be three buildings set inside the fort. The one to your immediate west is made of stone, and flat-rooved with wooden planks. It is quite squat in shape — possibly storage of some sort. The larger building to your north is of similar construction, though much larger, and with an angled wooden roof. A chimney puffs smoke, and you can see the glow of light coming from what must be windows beneath the eaves. You can hear the sound of merriment even through the storm: sailor song, shouting, and the occasional whistle.
Far to the northwest is a more densely-build structure with a flat, stone roof much like the one you stand on now. In addition your knowledge of a dock of some sort past the northern walls, you can also tell there is some sort of open area or courtyard near the northwest corner, though your vision of it is limited from your current vantage.
