Felim collapsed into the snow, exhausted. It felt like it would be the last fall this time, his limbs stiffening and flesh numb. The adventurer had heard of natives that thrived out here, men who slew bears and made coats of seal fur. But who could build anything out here...?
Just as he felt light start to fade, Felim cast his gaze up to see the sky one last time. He was startled - or would have been, if his body had the energy - to see a furred hood and a leathery face with a toothless grin. "Ho there, brother!" it spoke. "You came to just the right place."
The party has found the source of the strange creatures roaming the countryside. The rift in this reality glows with a silver hue, rippling with the wind but never moving. They step through and are immediately assaulted with the scent of rotting meat, some have to muster all their strength not to vomit. Strange cries similar to the beasts the party had faced before can be heard in the distance. Looking around, they see they are in a forest of grey and red rather than the normal brown and green. The trees are sticky to the touch and writhe, perhaps to get away or perhaps as a warning.
The deeper the party goes, the more the forest seems to slither and move underfoot. The cries get closer and more numerous. Creatures lurk in the shadows, all the same color of their surroundings. Whatever the party came in here for, they had better do it fast.
The forest of flesh is waking up, and it is so very hungry.
