Currency

There is 2 types of Currency in the game: Except plot driven events, for game balance you can't convert Sx to ProN or ProN to Sx.
 * Sx: You use Sx to buy things (mostly). In the Stineford magical library you can learn that this currency is generated naturally by monsters and that in very large amounts it can be used to ward against monsters but this power declines with time. So countries with huge amount of monsters are potentially rich and banks are not attacked by monsters.
 * ProN: Provisionary Notes are bill of exchange created by banks. ProN are used for Investments (mostly).
