((Well, in AD&D, most drow worship the evil demon lady Lloth as the head of their pantheion. One of the worst punishments for "weak" drow, or "tratiorous" drow is transformation into a drider, via Lloth's power, and banishment into the lower caves, or wherever. A drider is..kinda like a drow/giant spider version of a centuar. One of the favorite methods of excuction of prisoners, drow or non-drow, unfit for slavery is to be tossed to the driders. If you want, I'll post or send you the Monsterus Manual description.))
