The Drow, or dark elves, live in the Underdark for most of their lives, effectively enslaved by their cult-like worship of the Spider Goddess Lolth. They spend their days in a perpetual trance-like state (the Saol). Those who have broken from the Saol (the Dhúi Seacht) are considered abominations by the Drow communities and are ruthlessly hunted and slaughtered by the Spider Goddess’s personal assasins, the Bás.
