Jhernarth is a product of numerous waterways converging along its extensive voyage from the shadowy valley of Emeldimir to the shorelines of lake Rumak. It stands as the most prolonged west to east flowing river across the entirety of Brucrumus. The river bears the moniker of the renowned halfling explorer who meticulously navigated its entirety.
