Human: Generate for me a description of a dreary scene outside town with a large pipe belching steam thirty feet above the platform. Assistant: 
The summit of the tower spreads out in a large, round platform. The platform has been made from black marble to absorb as much ambient light as possible, and the sides of the platform are walled to a height of four feet to shut off light from the city below. Under a nearby overhang, several charts depict the nighttime constellations along with descriptions of the most popular ones. A large pipe rising from the platform's floor belches steam thirty feet above the platform.
