This system will function similar to a mini economy within nations. This auction will be accessible from shop plots in all towns. The rank number is insignificant, as everyone can put up to a maximum of 10 items at a time, and each item will remain for a maximum of 1 day. If not purchased within 3 days, the item will be deleted. I believe this feature can enhance secure trade and interaction among people within the nation. However, if a town within the nation is under siege, the surrounding towns and the sieged town will not be able to utilize this feature. If this feature is used from a occupied town, a certain amount of tax will be deducted and given to the occupier nation. Apart from that, the tax system will remain the same as the global one.
