Copied from IRC from a talk about towns with Caspian:
The mayor is whoever is assigned Mayor during the chartering. Cities have Magistrates. Towns have Mayors. Villages have Elders.
When a Village is promoted to a Town, the Elders must sign a Town Charter and appoint a Mayor. You register your Town with the County. As part of the registrations, one Elder becomes the Mayor, the rest of the Elders become members of the Town Council.
And it continues as you go up to City, etc... Magistrate & City Council.
Generally the Elders are the land owners who form the Village.
Example:
So let's you, me, and Magus buy land next to each other and put buildings on it. That's a "Hamlet". Then, after there's enough land, and certain buildings we can become a Village. Each of us become Elders. As Elders, we've got certain abilities. Mostly around Village management. If the Village continues to grow, and we get certain other buildings, as well as the necessary resources, we can register as a Town. Now one of us is made Mayor, and the rest become Councilmen. Again, we get certain abilities, and as Councilmen are considered Lesser Nobility. Both mayor and councilmen are now Aristocrats.
Right now the 30 players would buy land near each other, and then register to form a Village. The Village Elders can vote on stuff, with the vote weighted by the amount of land the Elder owns.
So the more land you own in the village, the more powerful you are within the village. If you own 51% of all the land in the village...
Selling land:
So let's say I owned 20% of the town's land. I could sell that land, thus making someone else an Elder. If I sold it to an existing Elder, they may become a majority shareholder, and could vote out the current Mayor and take over.
This is at a parcel level. So if you own multiple parcels, you could sell some of them. But you can't sell sections of a parcel, only lease.
