Altmer (High Elves): The inhabitants of the Summerset Isles, the Altmer are skilled in the magickal arts, maintaining long lifespans through a combination of lifestyle choices and magic. They are known for their aforementioned magickal arts, pride and their recent victory over the Imperial Empire.
Argonian: Dwellers of the Black Marsh, the Argonians are the lizard-tree people in service to the Hist. They are immune to most diseases, able to breathe in water and are skilled in stealth both on the battlefield and in the homes of the unwary. They are known for their alien minds, their adaptability and being the only race on Nirn to successfully beat back a Daedric (alien non-ancestor spirits) invasion through sheer force of arms.
Bosmer (Wood Elves): Natives of Valenwood, they guard it's plant-life with zeal, refraining from using it for food or material, relying on meat or imports to survive. Skilled archers, sneaky and competent mages the Bosmer also have the almost universally reviled custom of cannibalizing the dead, striking fear into their foes. They are known as cunning primitives throughout Nirn.
Breton: The inhabitants of High Rock, the Bretons are the result of generational interbreeding between the Nords and Altmer. Human in appearance, the Bretons have a natural resistance to the effects of magic. They are known throughout Tamriel for their politics, refined culture and food.
Dunmer (Dark Elf): The native populace of Morrowind, the Dunmer are the ash-skinned cousins of the Altmer. Worshiping the Daedra and respecting the dead, the Dunmer are versatile, skilled in magic, intrigue and combat. Known for their religion, assassins and games of intrigue.
Imperial: The natives of Cyrodiil, the Imperials lead the Empire that has for many years, ruled over the continent of Tamriel. The Oblivion Crisis (a Daedric invasion and succession crisis) of the last era has however, seen Hammerfell, Summerset Isles, Valenwood, Elswyr, Black Marsh and Morrowind leave the Empire. Even with these losses, the Imperial people are still crafty, being great merchants, refined diplomats and disciplined soldiers.
Khajiit: The cat-folk of Elswyr, the Khajiit form is determined by the
phase of the moon when they are born. Agile, cunning and crafty, the Khajiit have earned a reputation as thieves wherever they go. They treasure Moon Sugar, a substance which is used to make the illegal drug Skooma; both have addictive properties.
Nord: The warlike inhabitants of Skyrim, the Nords were the first humans to inhabit the continent of Tamriel. While a core region of the Empire, Skyrim's people fiercely maintain aspects of their culture, with a few mastering the Voice, the throat-magic of dragons. Though the Voice is honoured and held sacred, other magickal arts are seen as wrong or evil by most Nords.
Orsimer (Orcs): The cursed children of Trinimac, the Orcs have always been outcasts. With a homeland that has repeatedly been burnt down, rebuilt and moved, most Orcs master the arts of the forge, the mortar and pestle or the hammer simply to survive. Orcs mostly worship the Daedra Malacath or the Aedra (ancestral spirits) Trinimac, both being the same deity in different forms.
Redguard: The former inhabitants of sunken Yokoda and now settlers of Hammerfell, these men of dark complexion are known throughout Tamriel as great swordsmen. Like the Nords, the Redguards look down upon most magicks, save those of the Destructive nature.
