Hixinoag was an Argonian town in the province of Black Marsh. It was located north of the town of Slough Point, which served as a border crossing between Cyrodiil and Black Marsh, and was connected to Slough Point by the Commerce Road. It was a small collection of huts that were built in the mud of the swamps and possessed a site where the Underground Express could be accessed and taken to Gideon.
The villagers mainly subsisted on trodh, tiny fish that could be found in the swamps around Hixinoag. Due to it being built in the mud, Hixinoag tended to drift and change position like many other towns in Black Marsh.
