[Morsul the Dark]

This is sort of a two part question.

I've been looking for A full map of Middle Earth most I'm findingg have just the main continent f ME. So first part, How far down does Harad go and how far East does Middle Earth expand?

Secondly did Saurn just want Middle Earth (Gondr Rhohan Shire etc.) r did he want the world including Harad Far Harad the far East, etc.
