Lolth was once Araushnee, the consort of Corellon Larethian, and the keeper of elves who shared her darkly beautiful features. She was named the Weaver of Destiny and brought him two children, Eilistraee and Vhaeraun, before she betrayed him and tried to invaded Arvandor, along with Ghaunadaur, Malar and many other fell deities. For her crimes, Araushnee was banished to the Abyss in the form of a spider demon, where she took the name Lolth and ruled the Demonweb Pits, her domain. As the original patron of the dark elves, the Queen of Spiders established herself as the unchallenged ruler of the drow pantheon.
Since the events of the War of the Spider Queen, Lolth has transformed into a greater deity, and took the Demonweb Pits out of the Abyss.
She is cruel and capricious, embodying the absolute evil of the drow who live in the Underdark. She can be kind and aid those she fancies, but she thrives on death, destruction, and torture - including those of her own worshippers who have displeased her.
She has many avatars, but her true form is that of a human-sized, exquisitely beautiful female drow.
Fear is as strong as steel, while love and respect are soft and useless. Convert or destroy nonbeliever drow. Weed out the weak and the rebellious. Destroys impugners of the faith. Sacrifice males, slaves, and those of other races who ignore the commands of Lolth and her clerics. Raise children to praise and fear Lolth; each family should produce at least one cleric to serve her. Questioning Lolth's motives or wisdom is a sin, as is aiding nondrow against the drow, or ignoring Lolth's commands for the sake of a lover. Revere arachnids of all kinds; those who kill or mistreat a spider must die.
