What are the Lands of The Sun?

[Mandos]

I got this book (I think its called Tolkien Atlas) and on the map of Arda it shows this land east of Middle Eart called the "Lands of The Sun. Does anyone know what that is?

[bmilder]

It's probably Harad and the desert countries.

[Inoldonil]

I think he has seen some attempt at a world map in the Ages of Starlight, or something. If that's the case I'd guess it's just another continent, that is scorched by the Gates of Morning.
