Human: Make a concise location description of a room with two large boards listing the commodities for trade and a lithe Elf covered with chalk. Assistant: 
Traders move about this room, talking and haggling. The chatter in here is rather low, and tension can be felt in the air as deals are made and goods are traded. Two large boards listing the commodities for trade are suspended from twin chains bolted to the ceiling. A lithe Elf covered with chalk stands ready to change the boards at a moment's notice.
