Candle has things right regarding slots.
And I don't really mind y'all making too much history behind your culture, if there even is such a thing. I believe that, given that y'all will be dictating for the better part your own peoples' futures, there is not too much of a problem with writing a decently in depth history given that once the RP starts, you will be doing the same thing anyways, only with a tiny bit of poking and prodding here and there from me with my huge soup pot of GMship.
