Miron
A Miron is a unit used in the Wurm's economy logging system. It basically stands for a Million iron. (Iron coins are the currency unit in Wurm). This means that a Miron is equal to a Gold coin. In the beta version of Wurm, the Miron values would stay exactly the same throughout the map, unless the developers or game masters spawned some extra money. Now, because of the Wurm store, you can buy silver coins which can increase and decrease the values of Mirons in the economy.
