For small locations such as ships, towers, yew groves, and etc. For provinces and cities, the fee can only be set by the ruler of the province or city. The ruler must have garrisoned the province and be the owner of the controlling castle. Fees for provinces and cities are collected only when a garrison is present and a noble is sitting in the controlling castle. New fees do not take affect until the end of the month.
Fees appear in the turn reports.
To remove the fee from a location, set the fee to zero. Fees in provinces and cities persist until removed.
