Lake Nykosa is the largest lake in Allansia. It is a vast expanse of water in the middle of a stagnant, reed-choked swamp which stretches as far as the Sea of Pearls to the east. In parts of this swamp, flat salt beds have formed, which are harvested by the tribes who live in the marsh to be traded. The Craggen Heights run from south of Salamonis in the west to the western edge of Lake Nykosa in the east.
