Having never read a Drizzt novel (and never intending to, honestly), my appreciation of the drow comes mainly from the AD&D D and Q modules that dealt with them. There, they were exotic and powerful adversaries. Then came Unearthed Arcana, which gave us drow as a (somewhat overpowered) player character race. Players always like more options--particularly "cool" ones--but there the seeds were sown for over-familiarity and the contempt which usually follows.
So in trying to do a little re-imagining of the drow for my current campaign world, I wanted to chart a course between the purely villainous drow of the early D&D modules, and the posing, voluptuous viragos and emo-Elric wannabes of today. Since I've conceived the world's "high elves" as posthuman, glam anarcho-capitalists, and the "gray elves" as alien beings partaking of the melancholic sense of "passing" found in Tolkien's elves and Yag-kosha in Howard's "Tower of the Elephant," it seems proper to me that the dark elves should have pulp roots growing though Lovecraft's K'n-yan, and Clark Ashton Smithian decadence, which break the surface in the vicinity of Hellraiser, along the Left Hand Path, posted with fuzzy LaVey philosophy.
The primary goddess of the drow is Lolth, the Demon Queen of Spiders. Like all demons, Lolth seeks the destruction of all matter and form, the dissolution of the multiverse, and a return to a state of pure chaos--but she wishes to enjoy every sensation and fulfill every other desire prior to that end. She offers her faithful the same reward, and finds her chosen people enthusiastic followers.
There are legends that hold that Lolth was once an elven sorceress in a time before there were drow. In the pursuit of knowledge and experience beyond what she could find on this plane, Lolth trafficked with demons from the Abyss. Tricked by a demon lord and cast into the abyssal depths, Lolth was forced to live through a myriad of lives, deaths, and physical forms, experiencing all the inhuman horrors and pleasures that fiendish minds older than the earth can conceive. After lifetimes, she arrived at the realm of the demon lord, who she thanked--and then slew. At that moment, a new demon queen was born.
Drow are often as ambitious as their goddess. Implicit in her teachings is the opportunity for any drow to ascend and claim her power for their own.
Lolth sits at the center of her demonweb and waits, nourishing herself on the partially dissolved souls of those who have challenged her before.
