Lolth, the Spider Queen

HAUNTING LADY OF THE UNDERDARK
A former member of the high elven pantheon, Lolth is the ruling deity among the Drow that reside within the Underdark— a vast realm of caverns and caves that crisscrosses beneath the whole of Faerun.

She is said to rule with an iron fist whilst driving the civilization under her control to partial madness. Her influence is present among the minds of all Drow, as Gruumsh's is present among all of orcish blood.

WEAVING WEBS IN DREAMS
Whether it was the queen herself, or merely an avatar of her— Kawli and Ryltel faced down a form of her attempting through tear through the edges of the former's dreaming. Creatures of her ilk—Arcanamites and Driders, harkened her arrival before a protective force expelled Kawli and forced Ryltel awake.
