The Coven of Spiders

After the great scourge, most drow cities drifted away from the influence of Lolth as her powers were contained enough to keep them safe from the will of the spider queen. But there are some who remember, some who are still beholden to worship the old goddess of the drow. The coven of spiders is the remnant of the old religion among the drow. It consists of the most powerful drow who still follow Lolth. Lolth has gifted them with incredible power and tasked them with ascending her to new greatness above the blood of those who betrayed her. With the help of the dreadlord Adellum, the coven has taken control of Ungethal and plans to use it as a staging ground for their plans. The coven has the resources of about 50 elite, trained warriors who serve them but the real power of the coven lies in their priesthood and high council, where powerful magic assists them in their task.
Matron Briga The leader of the coven as well as a very powerful cleric of Lolth. 
Consort Phydrael The favorite mate of Briga and her second in command, a potent warrior in both magic and steel. 
Nylrhina A favored soul of Lolth, gifted with the powers of arachnomancy. Acts as a scout for the coven.
Inquisitor Inaxe A priest of Lolth who acts as overseer of Ungethal and roots out traitorous elements of the city.
Captain Valnos The leader of the Coven's forces and personally responsible for the safety of Matron Briga
Dro: The assassin of the coven, eliminating problematic figures who Inaxe can't easily get to.
