The notion from the OP I got was that this is Drow-only.
The problem isn't that I don't think a Good character is permitted. It's that I don't think I could play a Good character that would make sense in context. I would be too merciful, too trusting, not covering my tracks, not paranoid enough to keep the dark secret that I didn't kill all those people, but rather let them live and helped arm them etc. Having the level of CYOA that I feel you'd need to actually survive in a society as cutthroat and hyperviolent as Lolthite Drow tend to be either wouldn't be fun, or wouldn't actually happen and I'd get ganked.
