Well, as long as we can at least try to stay civil, we should be fine. Our characters don't have to like each other, and I suspect many characters will all but hate everybody in the group (my character included, she's about as apathetic as they come). But as long as we can work together without pulling blades every few minutes, we don't need to like each other. It's good dynamics to have uneasy relations within the group. But for the greater good, you sometimes have to work together with people you don't like. Usually when there is a group that is greatly unliked, they also have a lot to offer and are highly useful to have around. Comprimises will have to be made, and a lot of characters are going to be perpetually pissed off, but as long as we aren't attacking each other all the time, we should be fine. No one ever said we had to like it, just have to deal with. Paranoia is good survival instinct, and I would agree that you would want to watch the Sidereals as closely as possible. Just don't attack without provocation. That's just as likely or even more likely to cause mountains of problems...
