The Three Lands is what the Masters call their world.

They are, in order of importance:

Osrakum (the Black Land)

the Guarded Land (the Red Land)

the lands of the barbarians which lie around the Guarded Land (the Green Land). Of which the Earthsky is one example.

The Commonwealth consists of Osrakum, the Guarded Land and the Naralan, a land corridor linking the Guarded Land to the sea.
