Skyrim is a region set in the northern part of old Tamriel. It is the home of the Nords, large and hardy men and women who have a strong resistance to frost, both natural and magical. It is bordered by Morrowind to the east, Cyrodiil to the south, Hammerfell to the southwest, and High Rock to the west; the island of Salesroom lies to the northeast of Skyrim.
Many Nords from Skyrim emigrated to Bruma during the Imperial Invasion, to become citizens of Cyrodiil, in fear of being killed or imprisoned.
The region of Skyrim is also the location of the game, Elder Scrolls V: Skyrim.
