[Okay, that's a fair amount of questions. He tries to commit them to memory and think on them before replying.]

Not sure who the Fog God is, or what she wants. Just that she brought us here, and after a while we start changing. You won't know what kinda monster you'll be until it starts happening, and as far as I know nobody knows why she wants us like this. She might have a plan, she might just be bored.

[He sounds irritated at the thought of just being here on account of some god being bored.]

All I know is that once you've started changing, you'll feel hungry eventually. Only way to keep yourself from going insane is to feed on the people here. If you don't, you'll just lose your mind and attack someone anyway.

[He did it several times while in electric form, thanks to the Fourth God. At this point, Boone's opinion is that both gods can go to hell.]

And no. No way of leaving now, even if you try. Sorry.
