Along the roads into Gwymr/Frina the scattered lamp- and sign-posts mixed with bright-colored signs warning of trenches and sudden drops. Little glider-scorpions emerged from the deeper crevices, flitting in the night with the short, sporadic glides that named them. Often the whirring of bats rose with the calls and buzzes of the scorpions, but when one appeared, the other would grow silent, hiding or hunting.
We passed a few houses dotting the ravine at its widest, where the posts instead fenced off their yards. Here, netting rose from the fence-posts, and blocked any inward flight. The nets met big poles rising from the roofs, making the houses like spiderly pyramids.
