Each village would have a unique "brand" associated to it's products.
A brand is a set of buffs applied to crafted items in that village.
The brand evolves with time, the longer the village survives the better it's products will get.
Brand consists of attribute buffs, and realm like buffs as crop speed, animal ql, etc.
Brand applies to equipments and weapons that can be sold in Community Markets.
Identification of the village is optional for security reasons.
Destroying the village or taking over it would destroy the brand.
Brand is not transferable, neighbours villages could develop completely unique brands.
