in the walkthrough for Touching the Sky, after getting the Diamond Paragon from a Frost Giant, is the following:

well, there was only one hut with a mammoth skull, and it didn't have a book or a chest, it had an alchemy lab and a bunch of ingredients. i also could not find a tunnel anywhere. and as far as I can tell, this is the only area at this point in the walkthrough that has a "plethora of Falmer". what am I missing here?
