Kirit characters will be greatly regulated, but the main reason why I want players to take up them is because I want the kirit to be 'human', for want of a better word. I don't want them treated like mindless orcs or trolls or half-bloods. They are a people - with the same types of strengths and weaknesses as humans.

I don't know what you mean by PvP? You mean you don't want to combat with another player? Besides, this will not be an arena-style RP. As you said, it is more like Game of Thrones in that there is more politicking than fighting.
