A Gateway to Hell

A strange, abysmal black mist fills the air surrounding what is known as a gateway to hell. Too thick to see through, and smelling only of decaying trees, creatures are forced to use their ears to pass through this area. Until you're right upon it, you will not see anything -- 'til the mist breaks, and whatever unfortunate wanderer finds themselves in the middle of a narrow path through the trees. Branches are knitted together tightly overhead, so even without that horrible mist, light is scarce; the ground is too hard for prints to be embedded in it. If you have a good eye, you might spot the occasional skull -- prey bones, one might assure themselves, but certainly some are visibly that of a wolf.
