[IC] New Crobuzon & the World Beyond

[GM Marvel]

You spot a distant pinkish fog hanging over a body of water.  Suddenly you realize the background noise of a waterfall you heard earlier is gone.  While wondering if it were possible if the sound was swallowed up by the eerie fog, your eyes are drawn to the path.  The pinkish fog  is creeping slowly down the tunnel, inching toward all of you.
