The Dork Circus
This slow moving juggernaut of a river dominates The Nairn Lowlands, to which it gave its name long ago. It is formed from several major tributaries: the Glashain River, the Charagain River, and The Aol are all primary sources, with the Glashain and Charagain both splitting again into several others (most notably, the River Froth). The Nairn River proper is actually rather short, as scholars have long argued (without result) which of its tributaries should be called the Upper Nairn.
The mouth of the Nairn, where it flows into Sweetwater Bay to the Lacian Sea, is the widest river mouth in the known World, and, three leagues from the coast, one side cannot be seen from the other. The ancient city of Braucairn stretches along the northern shore, from its oldest citadel atop Glostrom Hill, with docks now abandoned to silt, to the newest docks, seven miles west.
