Nithiach is a wide and fast flowing river with headwaters in the Sinarag swamp.
In the Second Epoch, the Ningizzida Empire extended this river when they excavated a channel through a series of hills. With magic and slave labor, Ningizzida's military carved a canyon through the Aglak Rampart. This flooded the valley behind these hills, creating more wetlands. A decade later, the water had carved a path all the way to the Pearl Sea. Ningizzida's effort to block Farinteen's northern expansion failed. On their side the Farinteens went on to channel the river's flow to farmlands, bolstering game population, and turning Phanax into an important commercial port.
