The Broch, from above, looks like several nearby hamlets went in on a large wooden curtain wall. The buildings are generally low to the ground and wood and thatch; between them, an awful lot of informal encampment has been set up.
There's little in the way of very clear areas inside the wall; the clearest possibilities are a huge wood-pile which would make an awkward landing but is clearly free of people, the central gathering place of each hamlet with a smouldering fire-pit and wooden logs arranged as benches, which have the occasional person milling around, or the main central gathering area where the fire-pit is roaring quite impressively, which has more people but there's generally a little more space.
The wall is well supplied with archers on an internal walkway, and towers with arrow-slits facing both inwards and outwards; many of the inhabitants also appear quite heavily armed. The archers are mostly in greens and browns, whereas the other people are in a wide variety of styles, although green-and-brown and black-and-white with a single highlight colour are the dominant colour schemes.
Outside the curtain wall, the vegetation is flattened and burnt to leave a killing zone, which might theoretically be good for landing. A road suitable for two ox-carts to pass meanders out from the main gate in the wall; there are a few damaged, abandoned carts outside the gate.
Past the flattened zone, the dense jungle closes in immediately - in fact, it seems to be gradually encroaching on the empty space at a visible speed, if still fairly slowly for anything that isn't a plant.
