The land in the country all belongs to the state or a citizen entity, which sells it for money.
Namely that a land requires taxes of 500,000 FCOIN per year to guarantee its protection by the prefecture of Folium, Morithan and BellVerre.
Under no circumstances is it allowed to install a structure of any size on land that does not belong to you. Very serious consequences could follow.
To buy a plot of land, all you have to do is apply to the Folium government or in-game, send them a letter or make an appointment.
