Post Greyhawk Wars: 585 CY
This is the longest river in the Flanaess. Its headwaters are high in the Barrier Peaks, flowing through the Valley of the Mage before it flows all the way to Monmurg. It is not navigable by large vessels beyond Cryllor, and with the Keoland-Sea Princes enmity, little trade crosses this border. Of its tributaries, the Hool is broad with swampy banks, with only intermittent navigable and safe stretches of water; the Davish is a cold, rapid, narrow river unnavigable to larger vessels; and the Realstream is a rapid flow north of the Dim Forest and slower within that woodland, which allows excellent fishing.
