"The Leiden River Valley" is known for its excellent livable environment and has many cities of various sizes along its route,
but aside from Water City Nisk, which guards the estuary, and Brandenburg, the capital of Salt Lake County, the city with the most special status is the City of Wealth, "Golden Lion City," located in the midstream of the valley!
Though it's also known as the City of Wealth, and indeed many commerce associations and trading companies reside here, its main business has little to do with the thriving maritime commerce of this era.
In fact, it is a financial city led by great bankers!
Even the governor of Golden Lion City is the chairman of the board of a group called the "Netherlands Banking Group," and the garrison in the city has little connection with the Kingdom, as they are all elite private armies employed by the Bank Group.
