Sayell (🔊), the great river of the north, has its source in the springs of the Hills of Mansui near the northern border of the Kingdom of Evenhold. From here it flows north through the Tiaga Gorge and Davelmar Forest, then into the vast and scattered woodlands of the Northern Reaches, passing through several lakes as the land flattens. It finally reaches the territory of Sayell for which it's named, a region of bogs and marshland, and spreads into a delta as it empties in the Cold Seas roughly 100 miles west of Andport. From source to mouth is a distance of 600 miles, though the Sayell's winding path covers nearly 1,000.
