A strange cloud had been spotted drifting among the mists that form at the top of the plateau. It would form and disperse, and vanish into the trees. Eventually the cloud was seen to return time and again to the strange open area on the north side at the top of the plateau. Strange cries for help can be heard from it, the closer one gets.
They lured the group in, and they were forced to deal with visions of terror, acid and cold as they stumbled through a membrane and into a world of fog.
The world had short visibility, and was made of mostly water – fens, wetlands, marsh, bogs. A beach with strange sisters on it, a blue hydra like creature and swarms of insects, rats, fish and other things. It was hard to breathe, and some sections the group swam through caused lungs to fill with liquid.
One woman said her red haired sister had the way out, and that her beach cave held the key. She sent the group to her other sister in the dunes, where willow-wisps attacked the group while the woman watched on laughing. She bartered and wanted a trophy from a waterfall for the way in/help with her red haired sister. This trophy turned out to be a statue of the gods of light, in full protective splendor. Mark would have none of it, and forbid the group to take it and from then on took the group through the mist, from one mini-environment to another, searching for the beach. Harried and attacked by creatures, they came back to the beach, and assaulted the cave. Likely the snake familiar with the red haired witch saw them. Entering, it was dank, smelly and slippery. They entered an area where they were attacked by kelp and seaweed. A coral golem animated and attacked them just as a giant wave smashed through the caverns, sweeping half the characters and the golem into an 80 foot deep pit. Mark managed to slow the fall of the two of them, and sacrificed his life. He miraculously timed it perfectly, and while both were knocked unconscious, both lived. The rest were holding on to the remnants of a rope bridge over the pit, over 100 feet across. The sound of the cavern is filled with a familiar laugh.
