The Twist in the Dark Road
The dark road turns away from the hill to the south, leading north and east.
The hill to the south is topped with a black tower, whose battlements survey
the entire area. The gate to the tower is to the south of here, while to the
north the road enters a cold, dark pass. A cart track leads westwards. The
dark road looks like a black snake crawling through the grey grass.
