OK, so a small AT trinket for a rich collector could be, say, a high-function digital watch or a touch-sensitive electric lamp, whereas the governments are trying to locate advanced weapons systems etc? That makes sense.
(I mention collectors because a wealthy collector is the sort of thing that could be a good quest NPC).
Also, in terms of post requests - how does news and information spread in Frozen Skies, especially outside military channels? I'm guessing radio exists, but is it commonly used? Are there newspapers and is there any television/film? A cool idea might be to have no TV network or broadcasts but travelling mini-cinemas that stop off in different towns and show silent films (these were common in the early C20th in realspace IIRC).
