Heroes: Moryak, Ruthinn, Tarkin, Thoradin
The Heroes take advantage of the chaos in the city, and sneak inside the tower of Sorcere. They reach Gromph Baenre's chambers, and face the magical guardians and traps put in place to protect the Book of the Nine. With the book finally in their hands, they leave Vizeran's amulet in Gromph's study, and go back to Araj.
While Vizeran prepares himself for the ritual, the Heroes go back home to rest and say their goodbyes. They receive the visit of the ancient golden dragon Prothanter, and his retinue of metallic dragons. Each of them presents the gift of a powerful magical item to use in the battle to come. Only Prothanter bears no gift, yet he assures the Heroes that he has not fogotten them.
The day after, the Heroes go back to Araj, where Vizeran informs them that the ritual will be completed in one day. The Heroes teleport to Menzoberranzan, and ready themselves for the Rage of Demons to be unleashed on the drow city.
Several hours go by, when rifts in reality start to appear, uncontrolled surges of faerzness from which hordes of demons come forth, to battle each other in a frenzy on the streets of Menzoberranzan. Eventually, the nine demon lords make their appearance, and begin to tear into each other. As the battle unfolds, the chaotic energies of the fearzness fill the demons with their power. But it's a power that means their death.
Unable to contain it, one by one the demons literally explode, leaving behind only their stench. The demon lords battle each other, until only Juiblex stands (!) triumphant. Then the fearzness surges all around the massacre, and also the ooze lord is destroyed.
The Heroes survey the carnage, thousands of elves dead, buildings destroyed. Yet it seems that the battle is won. They couldn't be more wrong. As the faerzness surges once again, a portal opens above the ruin of Menzoberranzan, and Lolth, Queen of Spiders, makes her entrance, in the form of a drow priestess.
As she laughs and gloat upon the corpses of her former servants, she notices the Heroes and battle is joined. Even though she cannot use her full divine powers on the Prime Material Plane, she's a terrible foe. The Heroes fight her with all they have, with Thoradin losing his life in the battle. When Tarkin manages to cut her head, the Heroes have a few second to rejoice.
Then, from her drow corpse, the hybrid form of Lolth arises, a gargantuan monster with a humaoid torso and a spider body. With their powers almost completely spent, Ruthinn calls for a divine intervention from Sune, goddess of Love and Beauty. The goddess answers the call, and raises Thoradin from the dead, while at the same time infusing the Heroes with renewed strength.
Battle is joined again, and this time the Heroes have an ally. Plunging on the monstrous form of Lolth from above, the golden dragon Prothanter unleashes a river of fire on the goddess, then claws and bites into her.
Dwarves and dragon fight the Queen of Spiders; after a hard battle, Moryak aims his crossbow one last time, and hits Lolth square through the eye. The form of Lolth begins to discorporate. The Heroes have won the day!
