Human: Write a detailed description of a gloomy scene outside a town keep with logs and a band of the defensive palisade circle. Assistant: 
Thick slabs of roughly hewn wood securely fastened by stout diagonal battens of a darker wood make up the double massive entry gates. Centered in the line of logs spearing imposingly into the sky, the gates resemble a dark squared gem set in the thick band of the defensive palisade circle.
