If its because you think azerport is overdoing it, put simply its not. the location itself allows many fertile fields, and many of the domesticated animals to breed and remain healthy, while at the same time being perfect for growing flax which is a key component in linen, which makes cloth and clothing. I would assume we have such people that have learned over the many years how to harness it correctly and make clothing.
The many mountains provide all we need in terms of stone, Sandstone, Ore, Diorite, Andestie, Granite ETC... and we have a large forest that has a lumber mill, that brings in a consistent flow of lumber constantly, of Oak, Dark Oak and Spruce.
The fresh water all comes from the delta itself, which is easily filtered by primitive purification methods to remove all the soot from it. [I.E sand crystals or stone pebbles, that sort of thing]
Also, We have many fish by the bay, In fact it is almost teeming with it, as Fisherman can be seen constantly by the delta shoreline, or the sea itself.
All in all, We have grown to be self sufficient through many years of growth and the good location [albeit bad for defense] in terms of Self-Sustainment
though, We still lack anything exotic, and normally import such things.
