On the right of the first sketch is a kraal at the intersection of the earth roads or tracks, whose grid covers the Guarded Land. On the left is a diagram showing how this arrangement interfaces with the roads and their watchtowers.
The second sketch shows a typical kraal from above and from the side. A kraal is a circular space enclosed by a high, thick fence of woven hri-wicker, having a gate at one end, that is guarded by an overseers’ tower. A wide ditch surround the kraal and acts as a fire-brake during the burning off of the stubble (occurring every year at the end of the 6th and 12th months).
I used this diagram when I was writing the scene in The Standing Dead showing Carnelian and Osidian’s first night in a kraal. Their positions, and that of the sartlar, are shown. To help me get a feeling of the scale, I included a 2m high man, and a small rectangle representing the study I was writing in at the time.
