It's probably harder for most people to stay off the grid than you would think, but when you have unusual enough (and useful enough) talents, there's always someone willing to help you out, in exchange for something only you can give them. (Incentives. Supply and demand. The carrot is so much more useful than the stick--and so much less likely to get you hurt in return.) And their magic (it has to be their magic, even when they're a her instead of a they, otherwise the investiture would just fall apart) is uncommonly useful.

Right now they (definitely a they, right now) are kicking back and relaxing in a little no-tell motel. There's free wifi, at least, and the employee who discretely got them a room in exchange for clearing up a few issues also snuck them some decently filling snacks, so they're pretty much good to go until they decide to do something else. Or something interesting happens.
