Hurlen is a city built on the large number of islands where the River Tardy joins the River Silver just north of the Cataracts. It consists of about 30 islands, of which Grand Hurlen is the largest. Hurlen gets most of it's wealth from the goods Karkinor sends down the Tardy to be sent north or south on the River Road. Because of being built on the islands, Hurlen is generally considered impregnable once its bridges are up. Hurlen may be part of the princedom of Karkinor, or it may be an independent city-state; it's not clear.
