Skyrim holds four of the five highest mountains in Tamriel (the Red Mountain being the only one outside Skyrim).
Much of the northern half of Skyrim is cold and covered in snow.
However, the southern regions of the province are relatively mild.
The Nords long ago divided the province into nine geopolitical regions known as holds, each of which has a ruling jarl.
Each hold is a large area of land roughly equivalent to a county in Cyrodiil, each individually governed by a jarl who maintains court in the hold's capital city.
There are nine of them in total: Haafingar, Hjaalmarch, The Pale, Winterhold, Eastmarch, The Rift, Whiterun, Falkreath, and The Reach.
Winterhold, Eastmarch, The Rift, and The Pale lie to the north and east of the province and are known as the Old Holds and remain isolated from the rest of Tamriel, both geographically and politically.
In contrast, the western hold of The Reach has historically been more cosmopolitan and members of all the races of the continent have made their homes there.
Eastmarch is the eastern hold of Skyrim, and one of the four known collectively as the Old Holds.
As its name suggests, it lies against the province's eastern border, close to the Dunmeth Pass, the only passage to and from Morrowind in the area due to the high and rugged Velothi Mountains.
Windhelm is the only sizable city in the otherwise rural province due to the expansive hot springs which dominate the hold.
