in old worlds, you would have a large village that was supported by smaller villages and this could go out a few iterations. and in this current world we have hermits taking over old villages.
What i propose is an alliance system that will allow us to ally with a village, and then the members of the allied village will show up in our village permission list. this would allow an allied hermit to enter a friendly village and help while a player has to be away without sharing login info, as well as allowing a a king to visit cities in his realm without having to get shared permissions from a villager.
granted this is more helpful to smaller villages and hermits, but i think that it could have some decent RP and societal uses.
