These diagrams are based on chains found in the manual. I've re-arranged them slightly, to make links clearer, and added omissions such as ships and troops. Buildings in the chain are shown as straight text. Fields, materials and goods are shown in square brackets. Buildings or units shown in normal brackets indicate the product is also used to supply part of a different chain - the other part of the chain is shown elsewhere on the diagram. Curley brackets ("{}") indicate a ground unit trained at a fortress. Goods can be taken/stored via a Main Market or Warehouse at any stage in the chain, unless indicated with a tilde ("~"). *** Indicates materials are primarily stored for general construction work and house upgrading.
