- Main article: Skyrim
The original home of Men in Tamriel, Skyrim is located in the frigid north of Tamriel, between Morrowind and High Rock, and is the home of the oldest race of men, the Nords. Skyrim is a rugged, harsh, and unforgiving place of snow-capped, jagged mountains and wind-blasted ice fields standing in contrast to the verdant forests of the Rift and Falkreath Holds. The Fourth Era saw a dramatic change to Skyrim's northern coast during The Great Collapse of Winterhold when the glacier on which the capital city was built shattered and fell into the sea, taking much of the city with it. The College of Winterhold was unharmed however, and this has fostered a great deal of anger, suspicion, and resentment between the local Nords and the College Mages who insist they had nothing to do with the Collapse. The fact that the Nords have continued to dwell here is testament to their resilience and fortitude.

Called Argonia by its inhabitants, Black Marsh is home to the reptilian race of the Argonians. It is located in the south-eastern corner of Tamriel and is covered by vast, festering marshes, rainforests, waterways, and immense, impenetrable forests of Hist and mangrove trees.

Many cities of Black Marsh, such as Gideon, were originally founded by the Ayleids . Little else is known about this mysterious and ill-documented place.

- Main article: Orsinium The home of Orsimer, more commonly called "Orcs", is offically a territory, and not currently recognized as an independent nation and therefore not shown on any modern official map, encompasses a small area in the Wrothgarian and Dragontail Mountains. A difficult environment to thrive in as much of the landscape lies above the tree line, there are few abundant resources aside from rock and metals that require mining. Its geography, however, make it a place easy to defend against skirmishes and invading armies. This is fitting as Orsinium is no stranger to conflict and bloodshed which is exemplified in the ancient conflict which resulted its "birth" and the ascension of the Orsimers' king Gortwog in 3E who rediscovered the ancient location and reclaimed it for the Orcs of Tamriel.
