I think the possibility of the Bahro being mean is a red herring. For one thing, we've been nothing but nice to them, and they quite literally owe many of us their souls.
For another... to be blunt, if they had any intention to do us in, there's just no good IC reason I can think of that they haven't made a move yet, even if Live had ended yesterday with no gap of time in between. If they wanted us gone, they should have picked us off one by one when we went into the cave, but they didn't.
Plus I've never seen them act anything but kind and helpful, so I see no reason to suspect them now.
As for Yeesha, I think she's a good person, basically. She's flawed, sure, but who isn't? I like what Moke said one time about Yeesha being "all about the love," and I think that's very true, even if she shows it in odd ways. Yeesha's an odd person.
I also think Sharper is basically decent. He had a lot to learn, but he's learned some of it. He's made some bad decisions, one in particular, but I don't think he's evil. He is, however, an opportunist, without a doubt. I know a lot of people hate him, but I actually like him.
Personally, I think the peril will come either from an Esher/Kadish/D'ni-purity-ward direction, or from some as yet unknown foe. I don't think it's something natural like earthquakes exclusively. Natural disasters are devastating, but they aren't "evil" as they have no will, they just are. The only way I can see this being the threat is if the rumours were wrong (or just marketing) or someone is manipulating the natural world to cause them. Natural earthquakes would also be very difficult to stop, which would make for a rather frustrating game. ("You can't win. Ever. Your efforts are doomed to failure. Enjoy!"
