i know cyrodiil is basically a country and so are the other areas. tamriel is the world tho right? tamriel is earth basically? or just like a continent and nirn is the whole world?

Nirn is the world which Tamriel the continent is on.
Cyrodiil is a province of Tamriel.

Morrowind is a province of Tamriel.

Skyrim is a province of Tamriel.

and more

Yeh, I thought he'd get the idea when I mentioned province, given that those places are stated as provinces in all the games

i knew morrowind and skyrim and cyrodiil were like countries or what ever you wanna call them. i was just confused on tamriel and nirn

they are not countries per say, more like regions.
