In Yet Another Fantasy Gamer Comic, Arachne is a member of the mysterious Order of the Spider (this is what her spider tattoo means, although a cursory examination does not reveal this fact to every drow). This impresses Wolf so much that he would rather renounce being prince consort than go against Arachne. Yet Arachne does not have such a high standing with Lolth.
What is the Order of the Spider? Who are the members? What do they do?
(I don't doubt that part of the answer lies solely in the mind of the author, but I'm sure there are clues I've missed in >2000 strips.)
Oh, warning, to those who mind: there are drawings of naked people. Also, giant spiders and other critter.
