"Why do you think your world has always been contested ground, the arena of powers and immortals? It is Tamriel, the Realm of Change, brother to Madness, sister to Deceit."
Tamriel, also known as Taazokaan in the Dragon Language and the Arena, is one of the continents on Nirn. In Aldmeris Tamriel translates as Dawn's Beauty. Tamriel is a great melting pot of cultures and races; it is home to at least a dozen races, with dozens more having died out or changed.
