The Ebonheart Pact stretched over the provinces of Skyrim, Morrowind and Black Marsh. Its capital was the city of Mournhold, located on the mainland of Morrowind, the homeland of the Dunmer.
Bal Foyen, on the southern coast of Morrowind's Inner Sea, was a wild expanse of marshland until recently. Now much of it has been turned over to the Dark Elves' former Argonian slaves, who plant saltrice and herd guar in the former wastes.
Bleakrock is an island off the northeast coast of Skyrim between Windhelm and Solstheim. The hardy Nords who inhabit Bleakrock are mostly farmers and fisherfolk. A small contingent of Pact soldiers keeps a sharp lookout for pirates and raiders. This is the starting area of the Ebonheart Pact. All members of this alliance begin their journey on this island.
The fertile valleys of Deshaan are home to lush fungal forests, deep kwama mines, and broad pastures where netches and guar graze. But all pales before the magnificence of Mournhold, home of the Tribunal and capital of the Ebonheart Pact.
One of the "Old Holds", Eastmarch was among the first regions of Skyrim settled by the Nords when they arrived from Atmora. Its capital, Windhelm, is the oldest continously-inhabited human settlement in Tamriel, and was founded by Ysgramor himself.
On the border with Morrowind, the Shadowfen region has had more contact with Tamrielic civilization than most of Black Marsh—due primarily to the activities of the Dunmeri slavers who once operated out of the city of Stormhold. Now the Argonians are back in charge.
The ashfall from the volcanoes of the Velothi Mountains and from great Ash Mountain itself is Stonefalls' bane and benefit, fertilizing the soil where the land isn't too arid to grow crops. It was here that the recent invading army from Akavir met its bloody end.
Skyrim's southernmost hold has a relatively temperate climate, thanks to northern mountains that block the frigid gales of the Sea of Ghosts, and warming volcanoes in the Velothi Mountains to the east. Its capital is Riften, on the shores of broad Lake Honrich.
