Speaking from someone that works in the Military, I'm curious to know what you mean by independent. Most of us have been in Tumbleweed from the beginning, and when it comes to the danger, the Military has yet to put restrictions on us. They've been very accommodating and return they only ask not to use our abilities in front of the locals. That and of coruse follow the laws, which we're all used to those, no matter which Earth we come from.
As suggested above, what about the rest of the displaced? We've been in a position before where groups kept things from the rest, and it create a lot of mistrust. I'd like to avoid going down that road again.
