Looking for help in making a mod for EU III

[Caveira]

I was thinking about helping a guy make a mod for Europa Universalis III in this timeframe. I thought this would be the best place to get some help, since of you are pretty much uber when it comes to ancient history.

this is the prototype map he is using:


and things are improving quite well:


I'm really excited about this project. I figured if he got some help from this community, things would go alot smoother, not to mention realistic

Basicly, if you have any links/info about factions of this time, tribes, kingdoms, empires, republics, etc... images for flags, names, prefered unit types, etc, all of that would be cool.
