So, recently on the IRC, there's been lots of discussion of the Ancient World, so I figured we might as well make an official thread to discuss and plan exactly what happened, before putting it on the wiki or whatever.
What has been determined:

Note2: It was decided to scrap the name "Haradrim" for the big Southern Empire due to a wish to minimize borrowing from Tolkien. A current name many people have liked is "Ardharin" for their replacement.
Things to be determined:
The exact nature of these empires
A more precise timeline, especially of the spread of the Bronze and Iron Age
