"Holding aloft the Phial Frodo looked and before him he saw a greyness which the radiance of the star-glass did not pierce and did not illuminate, as if it were a shadow that being cast by no light, no light could dissipate. Across the width and height of the tunnel a vast web was spun, orderly as the web of some huge spider, but denser-woven and far greater, and each thread was as thick as rope."
