"Although Tamriel is the most well-known and important place in the world of Nirn (or Mundus), it isn't the only one. Far to the north of Tamriel lies Atmora, from which the Nords came to conquer Tamriel. Atmora, in the Elvish language, means 'Elder Wood'.
To the west of Tamriel lies the sunken continent of Yokuda, from which the people that are now called the Redguards came to take over Hammerfell.

To the east of Tamriel lies the continent of Akavir, which means 'Dragon Land'. Akavir is home to four major groups: Kamal, Tsaesci, Tang Mo, and Ka Po' Tun. It was once home to the Akaviri, a race of Man and, most notably, the Dragons, but the Tsaesci drove the Dragons and Men to extinction - it is unknown what happened to the Akaviri. Akavir has launched multiple invasions on Tamriel in the past. Although a line of Tsaesci did rule Tamriel for some time, it was replaced by the Septim Dynasty of rulers; all other invasions have failed.

Below Summerset Isle, just to the south of Tamriel, lies Pyandonea, the tropical home of the Maormer or Tropical Elves. Even farther south supposedly lies the lost Elven homeland of Aldmeris, or Ehlnofey, which was devastated in ancient times (hence the early migration of Elves to other continents, namely Tamriel).

The Coral Kingdoms of Thras, an archipelago southwest of Tamriel, is the homeland of the sload, a conservative amphibious sluglike race. The Thrassian Plague devastated Tamriel around 1E2200, after which a united Tamrielic navy ravaged and sank Thras into the sea. It has since recovered."
