The world's best web

I know that the herb master from Randol has learned to sew wonderful clothes from cobwebs. And even though she flatly refused to give the name of her supplier, I guess who supplied her with the web... I could tell our masters about my guesses - they have been sharpening their grudge against this mysterious benefactor for a long time - but I won't... if you bring me even higher quality cobwebs. She will have to go to the Temple of Oblivion itself... but what are the horrors of this temple compared to the anger of the merchants, right?
