Catha isn't but Elona is forgot its apart of the desert hehe.
I looked up some things on Wiki as I like to get into lore for MMO's, does anyone know when Yokuda was destroyed ? is it in Teso timeline or before it ? does seem a lot of places to add in the future though
Yokuda
Not much is known about Yokuda since it was nearly obliterated in an unknown cataclysmic event, but it seems to have a dull, rocky, hilly, desert landscape. It is known to be the original home to the Redguards before they rendered it uninhabitable.
Atmora
Atmora is a barren and freezing wasteland. It is this extreme cold that caused the water of the Sea of Ghosts that borders Tamriel and Atmora to become icy. This frozen land is also where the Nords of Skyrim are originally from, although not many trips back are made.
kavir
Next to nothing is known about the geography of Akavir. We are aware that the continent is split into four warring kingdoms, each boasting its own race: Tang Mo, Kamal, Ka Po' Tun, and Tsaesci. Akavir is known to have been a home to dragons. ]The Blades, originally from Akavir where they were known as the Dragonguard, but turned to serve Reman Cyrodiil in their search for a Dragonborn.
Pyandonea
Pyandonea is the island-continent located to the far south-west of Tamriel and home to the elusive Maormer. The island consists of dense rain forests which provide shelter for the southern water spirits. Due to its populace being Merrish, there is speculation that Pyandonea may in fact be part of Tamriel.
Thras
Thras, also known as the Coral Kingdom has been a powerful, antagonizing power against the Summerset Isles since before recorded time. The Sload may at one time have even called Summerset part of Thras.
Aldmeris
Little is known about Aldmeris (including if it still exists). The Altmer claim that this continent was the birthplace of both elves and mankind.
