The RP hasn't started yet, but I've put up the Evolution Phase intro for you guys to have a little look at -start gathering ideas. Hopefully it answers some questions, and sets the general tone. 

Technology-wise, the phase ends at 400 A.D. I've allowed for gunpowder, but disallowed its widespread use, along with metals stronger than iron. 

I understand that some of us may develop technologies unique to our own peoples and civs, my Dwarves for one will be looking at the cultivation of fungus. All I ask is that your peoples do not invent anything that might launch them centuries ahead of the rest.
