There's also, possibly, the notion of where in the world everyone is... Slee seems like she'd require Sorn already having that boat to reach her. And I haven't had the chance to read the other chars yet. I'm sure this could be easily solved, but, I mean, if Sorn's heading in a specific direction, that also seems like the sort of thing that might decide the order of introductions. ???

I do not really have any preference for how it's decided though, beyond, NOT IT! cuz, y'know, I don't even have a character finished yet. Ha!
