The Iron March is a trade road connecting Vludrecht and Gildoun. It is the most heavily defended trade road in all of Faerstice. The Vluds rely on trade to keep their people fed, so the safety of the road is incredibly important. This is also the main route that the armor of the Vluds and siegecraft of the dwarves flows into foreign markets.
Though it is heavily guarded, the Iron March is still susceptible to attack. The occasional pack of kobolds or dire wolves will set upon hapless merchants who choose not to hire an escort to accompany them.
