The Black River

A major watercourse of the western world-continent, flowing roughly southwest from its source in the Black Mountains of northern Pictland, marking the western border of the Aquilonia frontier. It had a swift current but "sullen" aspect at Fort Tuscelan, which implies that it must have been quite deep and carried a considerable volume of water. In its lower reaches, Black River flowed into Zingara, then angled westward to the sea. Its mouth was at Kordava, capital of Zingara. This area was an ancient agricultural center; there may have been a floodplain along the course of the lower Black River, with fertile silt deposited during each spring inundation of the land.
