Lolth

Lolth, the Spider Queen, is the primary deity of the dark elves. She is the goddess of deceit, shadows, and spiders. From her Demonweb in the Abyss, Lolth influences her worshippers and pulls various strings to implement her schemes across the Planes.
Many Lolthite icons and idols show an alluring woman with dark purple skin and silver hair, her abdomen swelling into the terrifying body of a monstrous spider. Her primary commandments are as follows:

It is better to be loved than feared, but you may certainly try to be both.

Misdirection, slander, and shadowed steps have more function than direct conflict.

Death to the elves who live under the sun, and death to all their allies!
