Shadowfen is the northernmost region of Black Marsh, homeland of the Argonians. The region is bordered by Deshaan in Morrowind to the north, and Cyrodiil to the west. The Ebonheart Pact is in control of Black Marsh, but there is a large presence of the Aldmeri Dominion in the region trying to take the province, and a powerful artifact known as the Mnemic Egg, for themselves. Shadowscales, Argonians born under the sign of the Shadow and sometimes taken into the Dark Brotherhood, can be found in this region.
