Most cities buy or sell one or more common trade goods, such as wool, beans or pipeweed.
It should be possible to earn a decent living buying and selling these items locally. Some trade goods, such as ivory and myrrh, are extremely rare, and may only be bought and sold in a few cities. These rare items may need to be transported across vast distances to find a buyer. Trade in these items is extremely profitable, and knowledge of such routes is jealously guarded by players. While ordinary trade goods are produced and sold though city markets on a monthly basis, rare trade items are only produced once each game year.
