Commodities

The main commodities the kingdoms share between themselves, including who has what and who lacks what.

''Meta Comment in the future some of these categories such as Spice, Dyes, Timber, etc... May get more details like it was done with the metals.''

Salt
Some say the way to a man's heart is through his stomach... And it certainly can be when you sprinkle salt on his meals! It's magic I tell you, it can make an orc grub taste like dull chicken.

Spice
A couple of wars have been started over some exotic spice, and the likelihood is, it wasn't the dumbest reason blood's been spilled.

Be it garlic, ginger, cinnamon, clove, coriander, pepper or black pepper, you can always use some spice in your life.

Timber
The mug you drink from, that plate you're eating on, that old cart on the street corner, the bustling market stalls, that flimsy house, the sturdy town palisade, you get it, everything needs wood.

Food
Beggars and peasants, soldiers and knights, nobles and clergymen, certainly all very different walks of life... Yet they all have one thing in common... They hunger.

Most food is made for local consumption, but a select few fares can withstand the journey, whether through human ingenuity or alcoholic properties. Such as salted fishes, dried meats, ale, wine, mead, and a variety of oils.
