Whoa :o This actually sounds really cool and thought-through! I hope it'll go really well, and from the sounds of it, it would be. It reminds me a little of the Shattered Era, that I was/am the co-GM for. It's kind of dead now, along with everything else, but it was an RP where there were two sides of Pokémon. The Knights, and the Mechanists. The Knights are the traditional 'curfew, strict rules, no freedom and 'peace'', and the Mechanists are alot more freeminded, like, they allow their members to wear clothes and whatnot.
I -really- loved that RP, because I had a super cool character named Caedmon, who was a Lucario. I usually play very happy/upbeat characters, or a kind of underdog sort of thing, but Caedmon was more or less emotionless. Not entirely, of course, but the way he -acted- seemed emotionless

He was going through quite alot of stuff by the time the RP ground to a halt, and I really wished I had seen the end of it all.
