So, this was the forest that they were gonna be exploring today?
Millie had heard rumors floating around that it was supposed to be a place that you normally shouldn't ever go into. Not unless you were prepared to get yourself lost somewhere inside. It had this odd quirk of making people lose their sense of direction, and only experts already familiar with the place, or those in possession of a decent Pokemon, have the best odds of making it out successfully.
Obviously something like that should deter any sane person the very moment they'd hear such stories, but...
