The River Brecclain is the largest of the rivers in Norica. Its source is the glaciers in the Shadowspine Mountains  as well as its tributaries the Whitefoam and Greyfoam Rivers. At Ardmore, the Lesser Brecclain branches off and flows into Blackwater Lake while the greater Brecclain continues east and then south into the  the Tescari Dominion, where it dissappears underground.
