On the back of the box, it says that there are a total of 49 above-ground levels (seven for each Province) and 230 below-ground ones. My question is, how many below-ground levels does each province have? Thanks.
There is no fixed number of underground levels per province. As far as I know there is no map of the entire game aside from the castle maps I made when translating the game and perhaps some partial ones. The game is very big and there are many small one or few screen underground corridors.
