The shaded tome reads as follows : Bauric has gone completely insane now. Yesterday we were attacked by some kind of wormlike creatures. The smaller ones weren't too much trouble but the larger ones nearly overcame us. Perhaps my time in the ruins has played with my sanity, but i would have sworn that i could feel the worm's presence in my mind. Stealing my essence and my sanity. I am now almost certain that i'll never make it out of here with my humanity. Sometimes i hear a great rumbling beneath the stone floors, as if some great beast is moving beneath the earth. Bauric has taken to sewing the hides of the giant worms on to the material from the shades. He has nearly an entire set of clothing made from them now. How he can stand to touch the hides i'll never know.
Clearly just a lead to tailoring research.
