Human: Make a first person description of a foreboding scene outside town with a boom and chains. Assistant: 
Constructed of red granite, the northern harbor tower looms high above the town walls. A walkway runs along the inside of the wall, though the base is too steep to allow you to climb up to it. To the southwest, the boom -- wooden logs connected by rusting iron chains -- stretches between this and the southern tower, preventing unknown ships from entering the village unless authorized by the guards.
