Every town has one resource. There are three resources available ingame. Harvesting any of them is a daily task and all can be more easily harvested with more strength and intelligence.
Fish[]
Fish, obtained by fishing in the sea or lake, is a two intelligence stat food. A boat is helpful in its harvest.
Fruit[]
Fruit, obtained in the Orchard, is a one charisma stat food. The use of a small ladder or large ladder can aid in harvest.
Wood[]
Wood, obtained in the Forest, is a good used in production of various objects by professions. It is the most government-intensive resource, as spare axes must be in the town hall to obtain it, and there are a limited number of spots.
