The inn provides the luxury of consuming ale for the peasants. An innkeeper is responsible to operate the building and distribute fresh ale from the stockpile, which is slowly consumed over time. Consumption rate is proportional to the number of peasants, however it can be raised or decreased with the help of a slider (available from the inn panel). Inn portions range from no rations to double.
Building an inn is a very costly investment, so it should be well-defended from fire hazards and enemy soldiers.
