Looking o the feature list and some other quotes about game mechanics it seems to me there is a real seperation between Towns and tribes. Unlike what we usually see in games where onl a tribe can start a town. Is this true? If so, to what extent is the seperation? Can a town change its leaders outside of control from a tribe? Can i create an open town which anyone could join? Perhaps i misread into the features.
Players become registered members of a tribe. 10 players or more must come together to form a town.
As towns increase in membership, they can claim more land and gain town abilities.
Hierarchical political system for towns.
These just suggest that in some instances there might be a seperation.
