The mighty Beyne River is one of the largest rivers in the heartlands, if not THE largest. It is a avenue of commerce, travel, and defense. The North Merchant Cities fall squarely on its banks (Karolak controls the sea exit), flood plains, tributaries, and adjacent lands. Although it is a shared resource, the Merchant Cities are considered its primary Sheppard. Many of the tributary Rivers of the Great Forest of Rhyl end of in the river or Lake Caolite that feeds it directly. The Beyne River is the primary trade route of the North Heartlands of the Steel Realms.
The river current is strong and swift, and boats (usually Beyne River Skidbarges) traveling west move at great speed. More travels east overland against the course of the river, though large boats with bound elementals ply the Beyne River in both directions.
The entry point of the Beyne River from Lake Caolite is referred to as Sillin’s Way.

A species of Giant Salt Rats developed on the Beyne River – ‘giant water rats’. They are almost as adapt at swimming as otters. They dwell in the sewers under major cities along the shore of river. They are now sacred to the goddess of rats – Irrigi and to the sect of the Runnel Rats.
