I think it was route 9 but I'm not sure. It was the swampy route.
And what is it with the horde of faceless men?
You mean on Route 14?? Where you are forced to walk in with your three travelling partners?
If so, then no, not really. Pokemon always adds something creepy into their Pokemon games, just to scare little children and entertain adolescent ones. Dunno why, it must be fine in Japanese media. xD
Hope I helped. :)
