Unique Coat of arms for each Village

Each village could have a coat of arms basically based on their biome colours etc. with random traditional heraldry elements (animals, weapons etc.).  It would make each village unique.  It could be displayed on the village flag / banner or above the central meeting place / bar / cafe. 

Perhaps when you buy tools, armour and weapons from the village they will have the village crest on the hilt (handle). It would make purchased items more special and collectable.

Also if you are have a positive popularity (you traded and didn't hurt a villager), when you make a banner you have the option of adding the village crest small in one corner, or multiple. 

Could be a new achievement to get four coat of arms on your banner, or perhaps an item with four different crests on them (so you'd have to visit and trade with four villages!).  That would encourage traveling, trading and exploring.
