Eastmarch is a hold in eastern Skyrim and has Windhelm as its captial with Ulfric Stormcloak himself as its Jarl which makes it the center of the Stormcloak movement.  Winterhold is to the north, the Pale and Whiterun are to the west while the Rift is to the south and the Dunmer homeland of Morrowind is to the east, across the Velothi Mountain passes.

Eastmarch varies greatly. The central and southern parts of Eastmarch are dominated by sulfurous pools and rocky crags, as well as Bonestrewn Crest. The Velothi Mountains form a spine along the eastern edge of the Hold, and a high ridge to the south leads up from the lowland sulfur pools to the Rift.

The Darkwater River joins the White River in the west, after which the White River merges with River Yorgrim at the Windhelm bridge and flows out into the Sea of Ghosts.

Two main routes run north to south in Eastmarch. They skirt the sulfur pools on either side. The roads are connected to each other at the far northern and southern ends, forming a continuous loop. There are also major branches off of this road: one west of Fort Amol leading to Whiterun; one west-northwest of Cragslane Cavern leading south to the Rift, and two near Windhelm. One leads to the Pale and beyond, and the other past farms until you hit the Sea of Ghosts.

There are two pathways into the sulfur pools from the east road: one runs from south of Kynesgrove to Witchmist Grove, and the other starts near Steamcrag Camp and heads west to Bonestrewn Crest. Other pathways in the Hold are to landmarks such as the dragon mound above Kynesgrove or Mistwatch.
