Those are fantastic! I've had a similar idea in mind, and have painted up a few of Bob's mounties and trappers. Ever since reading about the Mad Trapper of Rat River, I've found it fascinating.
I've also thought about including some nefarious Nazis, but have actually been leaning more toward some Soviet interference, perhaps Stalin's boys hunting down those who tried to escape via Alaska?
No werewolves, but I haven't ruled out the possibility of investigating those falling objects from the sky reported by Inuit generations ago...
