It would be interesting to be able to create a new village in a specific location by piling enough of certain supplies in one spot. It would give you a reason to stockpile large amounts of certain things. For instance, to establish a village which specializes in fishing, you might need to pile up:
10 fishing rods
20 nets
1000 days worth of food
10 bags of salt
500 stones
1000 logs
2 of each type of axe
10 assorted knives
500 pounds of fur
250 pounds of leather
100 cords
100 pounds of any combination of seeds
Put that all in one space, use the [M]ake menu to to make a fishing village, and poof! To make it more interesting and useful, you could also add certain cultural items to give you the ability to make it a certain desired ethnicity. So if you want a Kaumo village to trade with near your Owl-region homestead, you could build one and create a Kaumo cultural area around it. With enough time and tenacity, you could transform an area by creating multiple villages of the same ethnicity in the same general area.
