Port Salthar was a port city, within the Grand Duchy of Silkiah located along the eastern shore of Salthar Bay.

It was a strategically important city to the Grand Duchy, for much like Port Said on old Earth's Suez Canal, it protected the vital trade route that ran from Salthar Bay to Silkiah Bay. This trade route was the Salthar Canal, which saved travelers and goods the extra-long journey of traveling around Howard.

During the Siddarmark Civil War, it was a major supply depot for goods headed towards the war zone. (MTAT)
