For the short time our village managed to function, we had our LS who was the big boss and was responsible for all the inside stuff and general state of affairs. No making big decisions without telling him. Then there was the chieftain who's only concern was safety. Walls, militia, weapons, constantly reminding people not to leave their gates open
Nobody really made a fuss about who was Ls or chieftain. As long as they did their jobs properly it didn't really matter because whenever decisions had to be made they would be discussed in the village chat and everyone who had something to do with it would be asked for his opinion. And the regular villager's had just as much say as the LS..
Then the diplomats. These just chatted a lot with nearby villages and went on visits. It was 1, 2 villages per diplomat and this way we knew exactly what was happening everywhere. They weren't really chosen, just self appointed I think. We just knew who was friendly with which village so we'd ask them whenever we needed info or stuff.
Then the rest of the village. if someone needed something he'd just ask. There were specializations. Treeplanters, miners, farmers..
T'was democratic, every vote counted equal, at least to me. Everything was for mutual benefit anyway, we never did anything solely for ourselves.
