Taphae-Nes river system
The Taphae-Nes river system is the entire river system, including tributaries, bounded within the watershed of the rivers Theph and Nes. The name comes from the Arithide. The Taphae-Nes originates in the Alerryagi separately as the Theph and the Nes, its drainage basin covering much of the northern and western Eastern Seaboard of Arophania, the two rivers merging only mere kilometres away from the rivermouth, at the Calagian Pass in the Ordaryagi. The sheer size, length and volume of this river system makes it one of the Great Rivers of Arithia.
