magic users
I asked some questions about affiliating with the military, and was informed that if we did go that avenue, there was the possibility of them ordering us to act or not to act in a given situation. I'm glad to hear that you haven't experienced anything like that before, but I don't want to take the chance of that changing. We will continue to follow the laws, and to not display our magic in front of the locals, so that is not a problem.
The Avengers have their group, as do the X-Men, and the Guardians. Informally, people from the same universes have grouped together. The coalition will give magic users the same opportunity to similarly come together. Think of it as a sort of club or organization of people who have the same interests and skills. If any Displaced person is interested in learning how to cast magic, they may ask to be taught, we are not going to close our doors to anybody.
Tell me more about your experience - what group was formed, by whom, and what sort of mistrust was created? I'd like to avoid these things, too, and learning about what went wrong, we make sure it doesn't happen to us.
