Nasun River

The Nasun River is the greatest river of the Empire of Tieros. It flows south from the huge freshwater lakes bordering the Hordelands, through the marshes, out to the sea. The industrial city of Hama lies on the Nasun. It uses the power of the river to drive its industry via waterwheels. The noria at Hama irrigate many towns further from the river along the road. The fertile band along the Nasun, fed by its annual floods, is the main source of Lenthinar's food.

A nasunometer is located on the isle of Kifi, not far south of Hama.

At Hagari, an ancient system of locks brings boats down beside the cataract, which is decorated with a huge carving of a god.

Most of the population of Lenthinar and all of its cities, with the exception of those near the coast, lie along those parts of the Nasun valley south of Hagari; and nearly all the cultural and historical sites of Ancient Lenthinar are found along the banks of the river. The Nasun ends in a large delta that empties into the sea.
