There was a feeling of innumerable hairy spiders running over him from head to foot. The vague shape of a net formed and vanished in the gloom before him. He lashed out and hit the dark and the fog.
Swish-swish. It was moving away.
He stood still while the sound faded to a whisper and was gone. Then he started to walk. He was sure that what had just happened meant something, but what it meant was a different question. At least, he thought ruefully, he was wider awake now.
He walked on as the sky grew lighter. Then the fog shifted to show a solid mass of low blocky buildings across the road ahead. The road itself disappeared into a tunnel under one of the buildings. To one side, a waist-high metal rail closed off the end of one of the city's streets. Dan walked off the road toward the rail. His eye was caught by the building ahead. Each was exactly the same height, about two to three Earth stories high. They were laid out along a geometrically straight border with no transition between city and farmland.
There was a faint hum. Then a long, low streak, its front end rounded like a horseshoe crab, shot out of the tunnel under the building beside him and vanished along the road where he'd just been walking.
Now Dan saw a small modest sign beside the road.

—Swept—
Dan crossed the rail at the end of the street with great caution.
The Porcyn clothing he was wearing consisted of low leather boots, long green hose, leather shorts, a bright purple blouse and a sky-blue cape. Dan bunched the cape in his hand and thrust it ahead of him as he crossed the rail, for some races were finicky about their exits and entrances. The straight, sharp boundary between city and farmland, and the identical buildings, suggested to Dan that here was a race controlled by strict rules and forms, and he was making an obviously unauthorized entrance.
It was with relief that he stood on the opposite side, within the city. He glanced back at the sign and wondered what "Swept" meant. Then he gave his attention to the buildings ahead of him.
