I think certain concepts underlying the Drow society were derived from spider behaviors in the real world. In certain spider species, the females are physically superior to the males, and sometimes they eat the males after mating! The Drow worship Lolth the Spider Queen, so it makes sense that their social behaviors correlate more to the spider's way of living. In our digital gaming world, anyone can be anything without restriction. Sometimes I think that overcoming character limitations was originally meant to be part of the fun of the game, because that sort of connects to experiences most of us have in our lives.
