Tensions in Perrenland are boiling to the surface. The Southern Clans are mustering their troops as loyalty to Clan is tested against loyalty to Canton, the Voormann and a united Perrenland. You have been dispatched by the Voormann to investigate rumors of brewing civil war in the eastern Canton of Clatspurgen, specifically in the Kershane pass. It seems your fates are becoming ever more entwined with the destiny of Perrenland as a unified nation.
