Tatzelwurm are about the only dragons that populate the wild around Skelsaugh, more so the closer you get to the Tonumskel mountains. There are also the usual normal animals: Polar bears (though mostly near the ocean, where it's frozen by ice), wolves, etc.
It's fine if you finish after it's up, really. I'm just saying so it's easier for you to keep up o3o Until it comes to the Dragon Tamers having to interact, no one else will really be affected.
