Black Marsh/Government

There are several possibilities that could be the ruling body on Black Marsh. One of possibilities is the An-Xileel who seemed to be in charge of Black Marsh after the Oblivion Crisis. Possibly a political faction in Black Marsh that was part of the invasion of Morrowind.

Since there are references to the King of Argonia and an Argonian Royal Court, this might be the central governing body.

Another possibility is that the Hist are in control of the government in some way, or at least have an influence in it. Otherwise, its role is unknown.
