- "A broad river divided itself into two streams and on the island between them stood the city of Tashbaan, one of the wonders of the world."
- ―Chapter 4[src]
It notably surrounded the island on which Tashbaan was located. The river was broad and deep, the only passable fords being far to the west of the city. It ultimately dispersed into the Bight of Calormen of the Great Eastern Ocean.

After their arrival at Tashbaan, Aravis suggested swimming the river to avoid traveling through the city itself, but the idea was dismissed as impractical due to the apparent size of the river mouth. Inconspicuously fording the river downstream from the city was impossible, due to the many gardens and pleasure houses that lined the bank.
