Additionally, blacksmiths and trading posts offer items that cannot be obtained at the Guild. In the capital city of your contract nation, you can propose the invasion point of the next War, vote on war treaties, and allocate resources to create armaments and weapons. Each nation's focus is not determined by a single player, but by every player who is contracted with that nation.
