After passing through, they'll see a twisted landscape that resembles nothing like the real world. There are ruins here, older than thought. Some places are darker.
Others are brighter.
But the one thread in common is that none of it makes sense. The landscape shifts and changes on a whim, the denizens of this place are completely mad, up can be down, down can be up, powers may or may not work--which is a problem because there may be something out there in the mists. Something...waiting for them. Waiting for them all to venture deep enough in.
