Human: Produce a detailed written description of a spooky scene outside a road in a valley with a tower, guards, and a road. Assistant: 
The hillside climbs steeply northward, as sheer cliffs tower overhead to a dizzying height. The well-worn cobblestoned road winds its way towards the cliffs from the valley floor. To one side of the road, a small guard tower houses two elven guards, each of whom is diligently observing the few travelling this road at night. A lone torch burns at the base of the tower, casting a dim glow across the features of those who pass.
