One thing first. Don't be so afraid of saying something I won't like. I'm not afraid of a little bit of healthy argument, especially if it will lead for a better idea. I'm not looking to have you accommodate me, really. I'd rather create a great, believable, realistic world. Cool? Before we continue, though, there is one thing I would like to understand a little better. What separates the Nightwalkers and the Daywalkers? I agree that it wouldn't be just one thing, but I also don't think it would just be our random selections, right? I mean, we couldn't just flip a coin, and if it is tails the are Nightwalkers, right? So, what does separate them? I'm thinking, if I know this, it may help me quite a bit in understanding the question with which we are dealing right now.
