Demonweb Pits The Demonweb Pits was originally the 66th layer of the Abyss . By the end of the Silence of Lolth , Lolth had moved her domain in the Demonweb Pits to its own planar space . The realm is ruled over by Lolth , the primary drow deity , who resides in a huge iron fortress that moves under its mistress ' s will on spider - like legs . Her deific consort Selvetarm once lived with her there until he fell before a wielder of the " Crescent Blade " . Now every creature who resides in the Demonweb Pits answers solely to Lolth . Description . Old Demonweb Pits . The Demonweb Pits was a huge inverted cone of webbing formed of planar materials and inhabited by spider fiends , drow petitioners and the Spider Queen Lolth . It served as Lolth ' s dominion within the Astral Sea . When Quenthel Baenre and her companions visited the Demonweb Pits in the Abyss during the Silence of Lolth in 1372 DR , they found the realm unusually empty of souls . The realm consisted of black emptiness with an acrid smell and giant spider web . It was very hot there . The Pits were covered in corpses of monsters and demons dead and dying , particularly goristo s . Lolth dwelt in a black temple suspended in the web . Her stone face covered the entrance . When Quenthel ' s expedition returned to the same location in 1373 DR , they found the Demonweb Pits abandoned and in ruins . A gate guarded by abyssal widow s led to the new Demonweb Pits . New Demonweb Pits . The new Demonweb Pits was a plain of rocks with chasms and rocky gorges . There were many pits and craters . The land looked dead . There were giant petrified spiders with webbing over everything from the songspiders . There was a distant red sun during the day and eight bright red stars at night . There was a river of souls flowing to Lolth ' s city , an iron citadel in the Infinite Web . Lolth stood atop a dais in a temple on a pyramid with webs on the walls . There were a number of geographical features on the plane , including the Plains of Soulfire and the Pass of the Soulreaver at the base of the Mountain of Eyes . The plane was inhabited by spider s ( including songspider s ) , chwidencha . The Soulreaver dwelt in the Pass of the Soulreaver and was a gray spectral form , with a bloated serpentine body containing screaming drow souls . Gods and domains . All drow gods were originally located in the Demonweb Pits Lolth claimed to be the queen of them all . Lolth ' s son , Vhaeraun , maintained a realm named Ellaniath where he schemed against his mother almost constantly , an activity Lolth actually encouraged . His death by his sister gave her all of his dominion as well as his portfolio . Lolth ' s other child , Eilistraee , also had a place in the Demonweb when she was living though she rarely , if ever , visited it , having defected to the Seldarine long ago . However , with her death at Lady Penitent ' s hand , her dominion has ceased to be . Kiaransalee had her own citadel made of bones called Thanatos in a desolate area of the plane . She grudgingly worked for Lolth as her servant since her own layer of the Abyss was stolen from her by the reincarnated demon prince Orcus . However with her death due to the high magic of Q ' arlynd Melarn , she was forgotten by all her worshipers and her dominon now belongs to Lolth ' s will . Ghaunadaur resided at the very bottom of the pits , surrounded by slime and fungus that caused multicoloured lights to appear . However , in 1379 DR , fed up with the Spider Queen , he removed his dominion to the Deep Caverns .
