There are currently three types of villagers:
Guard - wears iron helmet and a sword, defends village. Is recruited by the Mayor and
can only capiture 25% of the village population.
General - Controls guards in combat, can order retreats and attacks. Guards are assigned on them. One per village and are promoted guards, promoted by the Mayor
Mayor - Sets taxes (broken for now), wears a leather helmet and if you kill it, you will become the mayor, therefore being able to set tax rates which directly affect village morale. If the mayor dies themselves a new one is elected with time.
GUI for the villages can be accessed by shift + right clicking a bell. There are more then one bell in some villages, therefore some bells wont open GUI, you have to find the correct one.
If you break a bell, the village will be dissolved, and if you place one a new village will be created.
This is the Alpha stage of the mod, therefore it will not have all the expected features other then what is listed above.
